I am a Mechanical Engineer. Right now i am working in a consumer durables industry as an industrial Engineer. I want get information about lean manufacturing, as you must have heard & also about new tools & techniques available to reduce the reduce the main 7 losses experienced in shop floor.
They are as follows:
1. Loss due to excessive Production
2.Loss of waiting Time
3.Transportation loss
4.Stock Loss
5.Loss in working itself
6.Moving Loss
7. Rejection Loss
I would be grateful if any one can guide me over this issue

Vikrant - some advice from practical experience.
1- Loss due to excess production: pace production to demand by working on two things at once pacing production to demand daily, and working to reduce change over effort to allow multiple changes per day (so you can pace production to demand). In one client, material handler set up the production kanban to store 3 days requirements, then the rest of the facility worked only to keep the kanban full - and once it was they all full stopped. Dramatic improvment in material throughput.

2 - loss of waiting: same issue - pacing production to one day's demand.

3 - Transportation loss: here hopefully we're talking about lost time not material = same issue pacing the production to a day's demand will force you to look at your workflow and batching quantities and make them smaller to speed the velocity of material through the facility.

4 - Stock loss: Shrinkage? Stealing or not finding or locating the item - not sure but cleaning out the shop floor and processing only a day's worth will free up space and make whatever is left, very easy to find.

5 - Loss in working itself: SMED single minute exchange of die + theory of contraints.

6,7 - Moving and rejection loss: Again theory of constraints and simple problem solving to identify (and hopefully to eliminate) root causes of material quality problems (Check machine, setup, and operator variability first).

Overall - SMED or Single minute exchange of die helps you look at work differently (internal vs external production activities) and sequence it differently to improve capacity. Eli Goldratt, wrote The Goal (about applying the Theory of Constraints to a small manufacturing facility) - absolutely the best book for you - learn all this in a fun instructive way - illustrates the principles and applications of all the things on your list. Enjoy.
