lean production
ABSTRACT
All manufacturing activities necessarily generate some form of waste. The manufacturing process does not consist of hundred percent of conversion of material and energy inputs into usable final products; some portion of the material and energy inputs inevitably ends up wastes. When the waste generated exceeds the maximum assimilative capacity of the environment it becomes pollution. This seminar focuses on LEAN productions, which aims at elimination of wastes there by reducing the environmental degradation.

1. INTRODUCTION
Lean production is an assembly-line manufacturing methodology developed originally for Toyota and the manufacture of automobiles. It is also known as the Toyota Production System. The goal of lean production is described as "to get the right things to the right place at the right time, the first time, while minimizing waste and being open to change". Engineer Ohno, who is credited with developing the principles of lean production, discovered that in addition to eliminating waste, his methodology led to improved product flow and better quality.
Instead of devoting resources to planning what would be required for future manufacturing, Toyota focused on reducing system response time so that the production system was capable of immediately changing and adapting to market demands. In effect, their automobiles became made-to-order. The principles of lean production enabled the company to deliver on demand, minimize inventory, maximize the use of multi-skilled employees, flatten the management structure, and focus resources where they were needed.
