  3. 0:25hello dear friends welcome again to nptl
  4. 0:28online course on Logistics and Supply
  5. 0:30Chain management so today in this
  6. 0:32session we'll extend our discussion
  7. 0:35we've started on reverse and Green
  8. 0:37Logistics we'll go into next the lean
  9. 0:40Logistics which is somehow will
  10. 0:42contribute in ensuring the reverse
  11. 0:45Logistics as well and Green Logistics
  12. 0:47and overall sustainable Logistics right
  13. 0:50so the basic concept under lean
  14. 0:52Logistics is how we can minimize the
  15. 0:55waste right so that is the basic concept
  16. 0:58of lean Logistics so we'll try to uh
  17. 1:01address the various aspects of lean
  18. 1:03Logistics in this session we'll discuss
  19. 1:05about the history we'll discuss about
  20. 1:07three M of uh how Japanese Industries
  21. 1:11are doing that because major uh if you
  22. 1:14talk about the Quality Concepts or major
  23. 1:17standards uh performance mattresses have
  24. 1:20come from the Japanese industry and then
  25. 1:24this lean PR uh manufacturing or lean
  26. 1:26Logistics concept is also implemented by
  27. 1:28Japanese organization first and then
  28. 1:31obviously now word is following these
  29. 1:34quality practices so we'll talk about
  30. 1:36the performance matters uh and uh what
  31. 1:39are the key indicators we'll talk about
  32. 1:41what are different methodologies and
  33. 1:43framework what are the challenges for
  34. 1:45implementing lean Logistics and then
  35. 1:47obviously we'll discuss about the case
  36. 1:49study so we'll spend couple of session
  37. 1:51on uh this lean Logistics as this is
  38. 1:54very very important part how we can go
  39. 1:58with more efficiency and effective iess
  40. 2:00and ensuring that the every time we can
  41. 2:03be uh 100% on time if you are talking
  42. 2:07about the delivery and if you are
  43. 2:09talking about quality also then 100% we
  44. 2:12should meet the quality as well as per
  45. 2:15the requirement of the customer so lean
  46. 2:18Logistics is to streamline the flow of
  47. 2:20material right so streamlining means
  48. 2:23when it is required let's say this is
  49. 2:26the supply
  50. 2:27chain uh and here our raw material
  51. 2:30suppliers are there and this is
  52. 2:33production line This is production line
  53. 2:35so many different stages are there and
  54. 2:38from here we are going for the
  55. 2:39distribution of the final product so raw
  56. 2:43material instead of storing the
  57. 2:46inventory here in your uh storage room
  58. 2:50right if why can't this happen that
  59. 2:52whenever I need 10 pieces so line wise
  60. 2:5610 pieces are coming on my production
  61. 2:58line so one by one I'll keep on
  62. 3:00processing those pieces and then the
  63. 3:02output will be there right so how that
  64. 3:05will be helpful in avoiding the
  65. 3:07inventory not only avoiding the
  66. 3:09inventory but also handling cost when
  67. 3:12you are storing in the store also the
  68. 3:15damages when you can do with the
  69. 3:17components when you are storing the
  70. 3:19product right and then the inventory you
  71. 3:22are maintaining all the time so that is
  72. 3:24also kind of capital you have invested
  73. 3:27which you will never utilize right if if
  74. 3:29you are maintaining that much inventory
  75. 3:31so lean Logistics uh focuses on
  76. 3:36eradicating all the inefficiencies or
  77. 3:39you can say if you are doing something
  78. 3:41in that Network in in any if you are
  79. 3:44doing some activity in Warehouse if you
  80. 3:46are doing some activity during
  81. 3:47Transportation or in manufacturing which
  82. 3:50is not adding any value to the End
  83. 3:52customer then that is something
  84. 3:54inefficient right so if you are saying
  85. 3:57that this for in invent
  86. 4:01you stored this product for 10 hours as
  87. 4:04a customer whether you stored for 10
  88. 4:07hours or 1 hour or you did not store you
  89. 4:09are directly shipping to me how it will
  90. 4:12you know add any value as a customer to
  91. 4:14me right so you are storing maybe
  92. 4:18because your supply chain is not smooth
  93. 4:21to ensure the smooth flow of the
  94. 4:24material maybe you are not insure about
  95. 4:26your demand then you are keeping the
  96. 4:28inventory but but you are keeping
  97. 4:30inventory how much you are keeping
  98. 4:32inventory as a customer as long as I'm
  99. 4:35going to your shop or your website I'm
  100. 4:38getting the product hardly matters for
  101. 4:40me what how much inventory you are
  102. 4:43keeping with your Warehouse right same
  103. 4:46is the case with packaging if I'm
  104. 4:48getting my product safe quality
  105. 4:51standards are met I will hardly bother
  106. 4:54about whether you are using uh single
  107. 4:56layer packaging double layer packaging
  108. 4:58or multi-layer Packaging
  109. 5:00right so these are some of the things we
  110. 5:02need to identify which are those
  111. 5:04activities which are adding value and
  112. 5:05which are non- adding uh nonv value
  113. 5:08adding activities so these are some of
  114. 5:10the definition you can just go through
  115. 5:12this lean Logistics focuses on
  116. 5:14eliminating waste improving efficiency
  117. 5:17in that way streamlining processes
  118. 5:19creating constant flow enhancing
  119. 5:21collaboration and achieving quality
  120. 5:24right so collaboration among
  121. 5:26stakeholders will be there throughout
  122. 5:27the supply chain only then this lean
  123. 5:30Logistics can be implemented right so if
  124. 5:33you are doing that you are more
  125. 5:35efficient and cost effective in that way
  126. 5:37if you are ensuring the lean Logistics
  127. 5:40so there is another definition which is
  128. 5:42describing lean Logistics to recognize
  129. 5:44and eliminate wasteful activities from
  130. 5:47the supply chain in order to increase
  131. 5:48the product flow and speed see these
  132. 5:52based basas of activities or byproducts
  133. 5:55you are producing like packaging this is
  134. 5:57not going to add any value so if you'll
  135. 5:59reduce this so that will also increase
  136. 6:03the speed of delivering the products and
  137. 6:05services so in that way you will be more
  138. 6:07efficient and then you can cut down the
  139. 6:09cost because you are not consuming those
  140. 6:11many resources so when if you are
  141. 6:13keeping the inventory for 10 hours you
  142. 6:15are consuming the resources for 10 hours
  143. 6:17so why to keep that uh inventory so
  144. 6:20there is one small video on just how you
  145. 6:23can utilize the maximum capacity in the
  146. 6:26container this is one way of
  147. 6:27implementing lean Logistics the same
  148. 6:30concept can be implemented in
  149. 6:31manufacturing and same com concept
  150. 6:34during your distribution and when you
  151. 6:36are moving through uh that distribution
  152. 6:39Network right so here is another video
  153. 6:41link you can just go through this video
  154. 6:43and you can relate the concept more
  155. 6:45closely with this right so uh dear
  156. 6:49students I'm again I'm assuming that
  157. 6:51that whenever I'm uh refering these
  158. 6:54video links you are going through
  159. 6:55because sometimes I'm including examples
  160. 6:57from there so you can for these videos
  161. 7:00okay so just you go through this link
  162. 7:03and we'll uh continue the discussion how
  163. 7:06using uh softwares or technology you can
  164. 7:09ensure the full utilization of the
  165. 7:11capacity of the container and how easily
  166. 7:14smoothly you can move the you know
  167. 7:16pallets inside the container and you
  168. 7:18just imagine when you are doing it
  169. 7:20manually how many hours you are taking
  170. 7:22to you know load that much capacity
  171. 7:25pallets those many pallets inside the
  172. 7:27container and then if you are talking
  173. 7:29about this kind of this is just simple
  174. 7:31arrangement of whatever uh uh these
  175. 7:35lifts you are using they have arranged
  176. 7:37just lift in that way that they are
  177. 7:39keeping inventory on that and within
  178. 7:41less than 2 minutes you are loading one
  179. 7:44full container right and then you are
  180. 7:46ensuring the maximum utilization of the
  181. 7:48capacity of the container but inside
  182. 7:51that pallet boxes whether you are
  183. 7:54utilizing fully those boxes or not that
  184. 7:56is another point so there also there is
  185. 7:58opportunity whether we can reduce the uh
  186. 8:01packaging whether we can make it more
  187. 8:03compact right so that you can uh in that
  188. 8:06way you can save some space inside the
  189. 8:09container this container traveling long
  190. 8:11distance so instead of maybe uh you are
  191. 8:15shipping 1,000 items can I ship maybe
  192. 8:171,50 items so then I will be more
  193. 8:20efficient so that per unit cost will
  194. 8:22come down because earlier whatever cost
  195. 8:24was we were dividing by 100 ,000 now we
  196. 8:27can divide by if you shipping 150 items
  197. 8:31and then per unit cost will come down
  198. 8:34right so if you'll Implement lean
  199. 8:36Logistics your efficiency will be
  200. 8:38improved you will reduce the cost and
  201. 8:41when you are efficient and reducing the
  202. 8:44cost obviously the customer is getting
  203. 8:47the product within less time and because
  204. 8:50you have having more margin in that so
  205. 8:52those margin can be used maybe you can
  206. 8:56keep some part as profit and some part
  207. 8:58you can share with your customers and uh
  208. 9:01maybe the customer will be more
  209. 9:03delighted with some offers and all that
  210. 9:05so that you can use or maybe you can
  211. 9:06provide some Advanced Services on that
  212. 9:09and then increased profit overall
  213. 9:10profitability you can ensure so and
  214. 9:13obviously more aile and responsive you
  215. 9:16will be uh uh in the market because now
  216. 9:21customer whatever customer is expecting
  217. 9:23in terms of services you are very quick
  218. 9:26handling all the disruptions you have FX
  219. 9:29exible supply chain distribution Network
  220. 9:31and you are responsible also at the same
  221. 9:33time you are efficient because you have
  222. 9:34eliminated all the waste so this lean
  223. 9:38term was uh coined by John krack and uh
  224. 9:43he discussed about this in his master
  225. 9:45thesis in 1988 where uh try to you know
  226. 9:49implement this lean Concept in
  227. 9:51manufacturing in warehousing shipping
  228. 9:54and various other functions but this was
  229. 9:56just uh the theoretical concept and and
  230. 9:59uh uh the just instructions were given
  231. 10:03how we can go for this what can be the
  232. 10:05different steps right but uh the
  233. 10:08properly this lean manufacturing concept
  234. 10:11was used by Toyota taii Ono uh engineer
  235. 10:15in Toyota who is well known in you know
  236. 10:17setting up the new quality standards and
  237. 10:20uh you know this lean manufacturing as
  238. 10:22well and they they try to you know
  239. 10:24eliminate the waste enhance the safety
  240. 10:26of the product and also touching the
  241. 10:28waterm line line for the Improvement
  242. 10:30where you will be more efficient and
  243. 10:32sustainable right so if we'll talk about
  244. 10:35this uh history now it organizations are
  245. 10:38also using lean Logistics right and uh
  246. 10:42because obviously this will happen only
  247. 10:45when just in time so just in time means
  248. 10:48again another tool which will help to
  249. 10:51ensure the lean
  250. 10:53Logistics so uh in that way we will try
  251. 10:56to optimize the value adding AC
  252. 10:59activities and will eliminate the non
  253. 11:01value adding activities like I told you
  254. 11:03you are keeping your inventory in your
  255. 11:06refrigerator in your Warehouse in your
  256. 11:08cold storage as a customer I'll hardly
  257. 11:12drive any value out of that you are
  258. 11:14putting uh double layer or triple layer
  259. 11:17packaging on your product it I'll not
  260. 11:19get any value as a customer out of that
  261. 11:22what value I'll get how many features
  262. 11:24extra you are adding into the product
  263. 11:26how is the quality of your product how
  264. 11:28quickly you are delivering the product
  265. 11:30and then how you are cost efficient in
  266. 11:32terms of what is the price right so
  267. 11:35talking about lean concept why we are
  268. 11:37talking about lean in logistics this is
  269. 11:40quite obvious so the share of this
  270. 11:43Logistics expenses somewhere 5 to 15% in
  271. 11:46some Industries somewh reach 25% also in
  272. 11:49retail right and we have talked about
  273. 11:52the reverse logistic concept also which
  274. 11:54is adding more uh uh you know verden on
  275. 11:58the uh Logistics industry to be more
  276. 12:01efficient in in terms of you know cost
  277. 12:03efficient so these are three quick
  278. 12:07pictures if you'll first see this I'm
  279. 12:10just giving you two three seconds you
  280. 12:11can just think about these pictures and
  281. 12:13what is happening and the terms are
  282. 12:16explained because these are again
  283. 12:17Japanese terms so mura muri mura so
  284. 12:21quick view first is you can see waste is
  285. 12:23happening overflow of the water second
  286. 12:26is the person is overburden what is his
  287. 12:29capacity he's taking more than that
  288. 12:31third is it is not balanced uneven so
  289. 12:35these three terms are muda muri mura how
  290. 12:38we can avoid these will lead to lean
  291. 12:40Logistics right first we'll take about
  292. 12:43muda this is the total capacity and we
  293. 12:45are utilizing this much only so rest of
  294. 12:48the capacity is waste this is waste how
  295. 12:50we can ensure that this if the room is
  296. 12:55that 100 people can sit and we are
  297. 12:57ensuring the AC facility for those 100
  298. 12:59people but only 10 are sitting at that
  299. 13:01time so then even the cooling facility
  300. 13:03is going in full way right so that way
  301. 13:07that small room can be used so that is
  302. 13:09unutilized capacity which is waste so we
  303. 13:13have identified seven types of waste in
  304. 13:17lean under lean first is your
  305. 13:20transportation T stands for
  306. 13:22transportation I stands for inventory m
  307. 13:25stands for your motion W stands for
  308. 13:29ating your o stand over production over
  309. 13:32processing and defects so anything you
  310. 13:35are doing here inventory again I told
  311. 13:38you the example is waste if I'm waiting
  312. 13:41for my product that waiting time is
  313. 13:43waste if let's say two workers are
  314. 13:46sitting on stage one stage two right now
  315. 13:49he is processing the product taking 2
  316. 13:51minutes and for that time he is just
  317. 13:53waiting because once he will process it
  318. 13:55will be shift to the de person so that
  319. 13:57means for 2 minutes he is sitting I so
  320. 13:59that is waiting if you are waiting in
  321. 14:01your maybe distribution network if you
  322. 14:03are waiting your career partner is
  323. 14:05baiting you you are placing the order
  324. 14:07through Jato so then Jato person career
  325. 14:10partner is standing outside the
  326. 14:12restaurant for 10 minutes or 15 minutes
  327. 14:14at that time you are preparing the food
  328. 14:16and it is taking time so how we can
  329. 14:18reduce that time how you can you know uh
  330. 14:22half cook item should be there that as
  331. 14:25soon as you are clicking on the order
  332. 14:26and your career partner is reaching at
  333. 14:29your restaurant your packet should be
  334. 14:31ready so how we can minimize if that can
  335. 14:33only happen if you have quick
  336. 14:34information sharing system right so if
  337. 14:37you are producing anything defect
  338. 14:39obviously is waste you cannot utilize
  339. 14:41that even if you will say we will repair
  340. 14:44we'll replace if as a customer I'm
  341. 14:47paying for new product why I should get
  342. 14:49the repaired one right so that is simple
  343. 14:51concept over production if you are
  344. 14:53producing something extra which is not
  345. 14:55required then it is waste motion if you
  346. 14:58are
  347. 14:59moving here and there in the workstation
  348. 15:01that means it is not designed properly I
  349. 15:03have included some examples also quickly
  350. 15:05we'll go through yes these are examples
  351. 15:07are there transport already we talked
  352. 15:09about if unnecessary movement is there
  353. 15:12during transportation that is waste
  354. 15:14customer is not going to uh derive any
  355. 15:16value out of that inventory you are
  356. 15:18keeping in terms of raw material in
  357. 15:20terms of work in uh in process in terms
  358. 15:23of finished good that is complete waste
  359. 15:25as a customer for me I cannot derive any
  360. 15:28value how how much raw material
  361. 15:29inventory you are keeping inside that
  362. 15:32motion this is what I was talking about
  363. 15:34waste of motion now this person is
  364. 15:36moving sometime to this bin sometime to
  365. 15:38workstation sometime he's carrying the
  366. 15:40product so jig Jag motion is there so
  367. 15:42that means while moving he is wasting
  368. 15:45time that is kind of extra motion extra
  369. 15:47waste this person is waiting for the
  370. 15:49call only then he'll respond to that so
  371. 15:52that is waste how you can ensure that
  372. 15:54smooth channel so that everyone every
  373. 15:57workstation should have some work to do
  374. 16:00and as a producer if you are producing
  375. 16:02more and then you are expecting that
  376. 16:03your customer should bear more than one
  377. 16:05cloth at a time that will not happen
  378. 16:07right if it is designed in that way only
  379. 16:10one t-shirt you can wear at a time so if
  380. 16:13other accessories you can wear over
  381. 16:14t-shirt or shirt you can wear some other
  382. 16:16stuff but you cannot wear two T-shirts
  383. 16:19at a time so even if you're producing
  384. 16:21more that will not help you then over
  385. 16:24processing let's say if you need to
  386. 16:26treat something at maybe 100°
  387. 16:29temperature and you you are using 150°
  388. 16:32right so that is something extra waste
  389. 16:34if you're cooking a simple example if
  390. 16:37you're baking your bread more than that
  391. 16:39temperature even in that process you are
  392. 16:42damaging that product as well and even
  393. 16:45you are wasting the energy so you
  394. 16:47consume more energy than required defect
  395. 16:50if anything is uh passing through your
  396. 16:53line which is defected so is kind of
  397. 16:56waste so some few based kind of waste
  398. 17:00have been included over the time if
  399. 17:02Talent is not utilized in mean Talent is
  400. 17:04also one kind of resource in the
  401. 17:06organization that is waste any resources
  402. 17:09I'm moving out of this uh recording room
  403. 17:12and still AC is on lights are on that is
  404. 17:14waste so how we can ensure that so
  405. 17:17sensor based lights you can use sensor
  406. 17:19based AC condition air conditioning
  407. 17:21facility you can use as long as you are
  408. 17:24there that will be functioning and after
  409. 17:26that it will be automatically turned off
  410. 17:29byproducts if you producing anything
  411. 17:31that is waste and if I'm saying I'm
  412. 17:34doing nothing in this organization still
  413. 17:36I'm getting salary is uh not something
  414. 17:39to be proud of that means you are not
  415. 17:41aligned to the goal of that organization
  416. 17:44and the problem is with the designing of
  417. 17:46the roles and responsibility of the that
  418. 17:49particular worker who is feeling that he
  419. 17:50is Idle not getting enough stuff to work
  420. 17:53right how we can implement this in
  421. 17:57inventory how we can
  422. 17:59uh minimize the inventory just to meet
  423. 18:02the demand we should not ensure the
  424. 18:04excess inventory right so just in time
  425. 18:07you can do that warehousing in Warehouse
  426. 18:10how F utilization of the warehouse in
  427. 18:13terms of capacity of the warehouse you
  428. 18:15are ensuring right and then minimum
  429. 18:18handling you can ensure right how you
  430. 18:21can ensure the proper stock rotation in
  431. 18:24the warehouse so that it should not be
  432. 18:27Obsolete and expired in the warehouse
  433. 18:30only right so those are we have
  434. 18:33discussed in warehousing uh session that
  435. 18:36what are the key performance indicators
  436. 18:38so all those indicators if you'll manage
  437. 18:40properly in that way you can be
  438. 18:42efficient how in your Warehouse you can
  439. 18:44use uh sustainable or renewable sources
  440. 18:46of energy to lighten your Warehouse
  441. 18:49right those kind of initiatives you can
  442. 18:51do trucks how you can ensure the full
  443. 18:53capacity you are utilizing the truck
  444. 18:56while rooting uh during your truck
  445. 18:58Transportation how you can ensure the
  446. 19:01minimum distance your truck should cover
  447. 19:04right so those many things travel if you
  448. 19:06are traveling somewhere for any work the
  449. 19:09travel time is wastage right so how I
  450. 19:12can reduce the travel time if I'm coming
  451. 19:15to you personally somewhere to your
  452. 19:16place so addressing those many audience
  453. 19:19will be time taking right so it is uh
  454. 19:22better way that we can record the
  455. 19:24lectures we can have the interactive
  456. 19:26sessions as well and then sitting at
  457. 19:28different places we can share the
  458. 19:30knowledge and information right people
  459. 19:33if people are there who like I told you
  460. 19:36waiting for their turn and uh for
  461. 19:39getting the product to be processed so
  462. 19:41that is waste if you're not using the
  463. 19:43you know skills of the of your Manpower
  464. 19:46even then that is waste so electrical
  465. 19:49Vehicles how electrical vehicles uh
  466. 19:52obviously can help you to develop the
  467. 19:54sustainable Transportation solution so
  468. 19:56this is all about muda waste how we can
  469. 19:59reduce the waste now
  470. 20:01muuri this this session will talk about
  471. 20:05what are the different types of uh
  472. 20:07issues are there when we are talking
  473. 20:08about lean manufacturing or lean
  474. 20:10Logistics in the next session we'll talk
  475. 20:13about what are the different
  476. 20:14methodologies we can use where we can
  477. 20:16ensure the lean practices within the
  478. 20:18organization so overden so this is
  479. 20:21because of why you are feeling overden
  480. 20:24because maybe last two days you did not
  481. 20:26work so now you are over occupied that
  482. 20:28is one reason right or maybe there was
  483. 20:31no demand for uh if you are barber or uh
  484. 20:35you are doing some giving some Services
  485. 20:37right so for 2 hours there was no
  486. 20:40customer for next 10 minutes maybe 10
  487. 20:43turned up right so then how you will
  488. 20:45manage that you are overburden then
  489. 20:46right but in Services you cannot avoid
  490. 20:49those things right so if you are doing
  491. 20:51overburden kind of thing there will be
  492. 20:53breakdowns there will be absentismo
  493. 20:55[Music]
  494. 20:56are now feeling over burden and these
  495. 20:59are some of the example when you will
  496. 21:01fear
  497. 21:02overburden when you are doing those
  498. 21:04processes you are not trained for you
  499. 21:06don't know how to do that poorly laid
  500. 21:09out workplace where the workplace is not
  501. 21:12designed efficiently and because of that
  502. 21:14you are lacking with your work unclear
  503. 21:16instructions out obviously if you are
  504. 21:18not clear about the job how you'll feel
  505. 21:20you will be feeling all the time uh
  506. 21:22overloaded right lack of proper tools
  507. 21:25and equipment obviously will lead the
  508. 21:27pending of the work fluctuating demand
  509. 21:29is mura right so if fluctuating demand
  510. 21:33is there even then sometime demand there
  511. 21:34is no demand and then there suddenly
  512. 21:37demand will come so overburden will be
  513. 21:38there lack of proper maintenance will
  514. 21:40lead to overburden unreliable processes
  515. 21:43poor communication roots in terms of
  516. 21:45because you could not identify that how
  517. 21:48much demand could be for maybe the next
  518. 21:51few uh months so then you predicted it
  519. 21:54wrong for the season and then now you
  520. 21:57are overburdened doing extra shifts and
  521. 21:59double shifts and all that in that way
  522. 22:01you are putting extra load on your
  523. 22:03system Your Capacity is this much but if
  524. 22:05you'll stretch Beyond Your Capacity so
  525. 22:08then beer and teer and one out will be
  526. 22:10there third point is unevenness now
  527. 22:13unevenness is sometimes because I did
  528. 22:15not work so now sometimes I'm not
  529. 22:18working at all and then maybe for next
  530. 22:20two days I'm uh all on the work from
  531. 22:24morning to evening so if that thing is
  532. 22:26happening so that means that you are
  533. 22:28inconsistent in that way so you should
  534. 22:32smooth out this right the very basic
  535. 22:34reason why you should smooth out your
  536. 22:36production process because when you have
  537. 22:39overburden in that process you'll
  538. 22:42quickly you know process the things and
  539. 22:44then you will produce the defected items
  540. 22:46you may damage the products so quality
  541. 22:48will be compromised and this is very uh
  542. 22:52common uh example or obvious things if
  543. 22:55I'm giving you assignment and I'm saying
  544. 22:58that maybe after 4 weeks you you need to
  545. 23:00submit it in the very first week you
  546. 23:03will be just thinking about the
  547. 23:05assignment oh we have one pending
  548. 23:07assignment second week then you'll start
  549. 23:09calculating okay these many days are
  550. 23:11left okay I need to you know work out
  551. 23:13little bit for that what is that topic
  552. 23:15okay what can be there in that we will
  553. 23:17think just third week now you are
  554. 23:19approaching next week is the submission
  555. 23:22date okay let's start something working
  556. 23:24on that let us start at least the
  557. 23:26introduction part of that and in the
  558. 23:28last last week we are targeting 17 to
  559. 23:3080% right so this is the human tendency
  560. 23:34so we are usually stretched up in the
  561. 23:38last week of the month when we need to
  562. 23:39meet the your uh whatever targets were
  563. 23:42set in the initially and because this is
  564. 23:45happening with all uh stakeholders even
  565. 23:49we will feel the shortage of the raw
  566. 23:51material supplier because raw material
  567. 23:53suppliers are also behaving in the same
  568. 23:55pattern that Hy stick kind of graph you
  569. 23:58are get getting that in the first week
  570. 24:00uh so in that way we need to smooth out
  571. 24:02the production throughout right so in
  572. 24:04that way we can avoid the
  573. 24:07unevenness principles of lean Logistics
  574. 24:09eliminating waste is the basic principle
  575. 24:12if you are doing something you don't
  576. 24:14know how it is adding value that is
  577. 24:17waste improving efficiency if you will
  578. 24:20eliminate the waste obviously the cycle
  579. 24:22time will be reduced if you are keeping
  580. 24:24the inventory uh minimum inventory or
  581. 24:28you are making minimum stoppage in the
  582. 24:30warehouse Center you are just doing the
  583. 24:32cross talking so that means that much
  584. 24:34time you are not wasting you can make
  585. 24:35the quick delivery so one step is
  586. 24:38related to The Next Step if you'll
  587. 24:40improve the suppliers automatically your
  588. 24:42next chain will be improved your
  589. 24:44manufacturing will be smoo out if you'll
  590. 24:47ensure the smooth manufacturing your
  591. 24:49next distribution network will be uh in
  592. 24:52that way streamlined so you need to
  593. 24:55streamline the full distribution Network
  594. 24:57so this is what I talked about
  595. 24:58streamline the processes all unnecessary
  596. 25:01steps which are not adding value so for
  597. 25:04that which are not adding value you need
  598. 25:07to improve the visibility what is
  599. 25:09happening if 100 people are coming in my
  600. 25:12organization daily I need to analyze
  601. 25:15what the people all those people are
  602. 25:17doing what is the work on their
  603. 25:18workstation I cannot design workstation
  604. 25:21for a one person who where he is heavily
  605. 25:24loaded and the other person he is
  606. 25:26enjoying all all the day right so that
  607. 25:28cannot happen so then creating constant
  608. 25:31flow so if those those many stages are
  609. 25:34there all should have almost equal work
  610. 25:36to work on the workstation right so that
  611. 25:40constant flow we need to ensure and I
  612. 25:43told you this will start with your
  613. 25:45supplier and if your supplier is in that
  614. 25:48way smooth your manufacturing will be
  615. 25:50smooth and if your manufacturing is
  616. 25:53smooth your distribution network will
  617. 25:55work in a smooth way and in the end
  618. 25:58ontime delivery will happen to the End
  619. 26:01customer right so that way you need to
  620. 26:04enhance the collaboration with all the
  621. 26:06stakeholders so lean concept cannot be
  622. 26:09implemented with one particular
  623. 26:10organization within manufacturing only
  624. 26:13right achieving quality so because very
  625. 26:17simple example if you are storing any
  626. 26:19product for 2
  627. 26:21months or the product you are storing
  628. 26:24only for 10 days obviously the quality
  629. 26:27will be degraded if you have not used
  630. 26:30that product for 2
  631. 26:32months if you are handling you are
  632. 26:34moving in the warehouse here and there
  633. 26:36just to manage the space even then you
  634. 26:37are damaging the quality right so as
  635. 26:40long as so you have the demand your
  636. 26:44distribution network is efficient enough
  637. 26:47and you are ready with the product in
  638. 26:49cck view so then it should be shipped to
  639. 26:52the market as soon as possible Right
  640. 26:55only when you will ship the product to
  641. 26:57the market only then you will be able to
  642. 26:59generate that Revenue out of that and
  643. 27:01when you are not storing for longer you
  644. 27:03can maintain the quality of that so
  645. 27:05these are some of the performance key
  646. 27:07matrices already we discussed these uh
  647. 27:10terms in terms of when we talked about
  648. 27:12the uh Logistics performance but in
  649. 27:14terms of lean Logistics we'll see how
  650. 27:18these things are adding towards the lean
  651. 27:20Logistics on time delivery how many
  652. 27:22times we are on time so if you have
  653. 27:26reduced the based activities you will be
  654. 27:28on time lead time how much time you are
  655. 27:31taking to deliver the product if you are
  656. 27:34having shorter lead time that means you
  657. 27:36have uh streamlined your processes and
  658. 27:39you are consuming the minimum time
  659. 27:41during the distribution Network
  660. 27:43inventory turnover if you are keeping
  661. 27:45minimum inventory that means quickly you
  662. 27:48are replacing the stock you are moving
  663. 27:50the material in the market and quickly
  664. 27:52you are replacing the stock that means
  665. 27:54your minimum time your inventory is
  666. 27:57making the temporary stoppage in your
  667. 27:59Warehouse order accuracy how many times
  668. 28:02you are delivering the accurate order
  669. 28:05accurate order on accurate time with
  670. 28:07accurate quality right so that is means
  671. 28:10complete order transaction cost per unit
  672. 28:13if in Bur truck you are carrying 10
  673. 28:16items and cost is 100 so obviously
  674. 28:19carrying one unit your cost will be 10
  675. 28:22Rupees if I'm carrying maybe 20 items in
  676. 28:25the same truck same cost will be there
  677. 28:28maybe the cost will be 5 rupees may not
  678. 28:30be same if uh maybe it will increase a
  679. 28:33little bit even then per unit cost will
  680. 28:36reduce maybe from uh 10 to it will
  681. 28:39reduce 6 rupes per unit or 7 rupees per
  682. 28:41unit so you need to ensure the complete
  683. 28:44uh you know utilization of the uh
  684. 28:47capacity this is Warehouse utilization
  685. 28:50how much space is utilized cycle time
  686. 28:53for any activity cycle time is when you
  687. 28:55are starting and when you are ending so
  688. 28:57you need to record the cycle time of all
  689. 28:59the activities you are doing during your
  690. 29:01distribution Network dock to stock time
  691. 29:04how much time you are taking you
  692. 29:06received the stock and then it is on the
  693. 29:08invent uh your uh Warehouse shelf for
  694. 29:11selling purposes right so how quickly it
  695. 29:13is moving that return rate high return
  696. 29:16rate that means your products are
  697. 29:18meeting not meeting the expectations
  698. 29:21defects are there so that means your
  699. 29:23manufacturing is somewhere in the
  700. 29:24question if you are damaging the
  701. 29:26products during your distribution
  702. 29:28then there is a question with the
  703. 29:30packaging with the handling so that
  704. 29:33return rate you need to analyze so order
  705. 29:36fulfillment cycle how quickly you are
  706. 29:39fulfilling the order when you are
  707. 29:40receiving the order and how quickly it
  708. 29:42is fulfilled perfect order rate perfect
  709. 29:46order rate is not only ontime delivery
  710. 29:48ontime
  711. 29:50delivery complete order fulfillment
  712. 29:52intact product I told you on time with
  713. 29:56quality right and your complete order
  714. 29:59should be delivered right and then back
  715. 30:01order rate back order is something if
  716. 30:03customer is coming to me I could not
  717. 30:06meet the demand because insufficient
  718. 30:08inventory was there so then I'll that is
  719. 30:11a kind of back order so maybe I'll take
  720. 30:14some time maybe next few hours I'll
  721. 30:16deliver next few days I'll deliver so
  722. 30:18that is back over it so how we can
  723. 30:20reduce this back over order rate that
  724. 30:23will help uh when you will analyze you
  725. 30:26know uh perfectly your market conditions
  726. 30:28and perfectly your demand supplier on
  727. 30:31time delivery performance how many times
  728. 30:33your suppliers are delivering on time so
  729. 30:36you can develop the schedule for the
  730. 30:38suppliers and you can record the
  731. 30:39performance so that next time when
  732. 30:42giving orders you can keep in mind as
  733. 30:44one of the parameter that this supplier
  734. 30:46is mostly on time 90% on time 95% on
  735. 30:50time so we should give maximum order to
  736. 30:52this order lead time variability if one
  737. 30:55supplier is like that in one order he
  738. 30:59delivered order two days before for next
  739. 31:01order he is delivering maybe 5 days late
  740. 31:04so all the all always there is
  741. 31:07inconsistency so in that way that
  742. 31:09supplier is not reliable you can never
  743. 31:12rely on that if it is consistently late
  744. 31:15we can take that margin that instead of
  745. 31:17five days he will take six or seven days
  746. 31:19so we are ready for that those many days
  747. 31:22but sometimes he is delivering in 3 days
  748. 31:24sometimes in 10 days then we cannot plan
  749. 31:26for that shipment Dam damage rate during
  750. 31:28distribution how many products are
  751. 31:30shipped how uh damaged how many what is
  752. 31:33the percentage so that you can see
  753. 31:35sustainability Matrix you need to record
  754. 31:38the carbon emission during your
  755. 31:39distribution warehous Transportation
  756. 31:41energy how much you are consuming waste
  757. 31:44how much waste as byproduct you are uh
  758. 31:47uh generating and then you need to
  759. 31:49engage your employees you need to
  760. 31:51provide the training to your employees
  761. 31:53only then motivated employees will work
  762. 31:55properly so this is all about about uh
  763. 31:58the various concepts of lean Logistics
  764. 32:00right uh and we have seen how we can
  765. 32:03what are the different types of waste
  766. 32:05how we can address that in the next
  767. 32:06session we'll continue this discussion
  768. 32:08we will be discussing on the various
  769. 32:10methodologies to overcome these waste so
  770. 32:13these are some of the references so
  771. 32:15that's all from this session thank you
  772. 32:17very much
