JUST IN TIME PRODUCTION SYSTEM-I

We have progressed our discussion on Lean Production Systems and Just In Time Systems and we will now focus our attention upon Lean Systems in Services, Operational Benefits associated with JIT. We will also note some of the common Implementation Issues along which the Organizational face while implementing JIT. We also need to know what single Kanban System is and solve some examples.

Characteristics of Lean Systems: Just-in-Time

Continuous Improvement with the help of Lean Systems is possible if Operations Managers are able to focus on some of the common characteristics of Lean Systems, which include:

  1. Pull method of materials flow
  2. Consistently high quality
  3. Small lot sizes
  4. Uniform workstation loads
  5. Standardized components and work methods
  6. Close supplier ties
  7. Flexible workforce
  8. Line flows
  9. Maintenance
  10. Automated production
  11. Preventive maintenance

The figure below of a ship sailing through waters is a great representation of an organization carrying its business with hidden rocks (barriers) like scrap, unreliable suppliers and capacity imbalance, carrying the threat of sinking the ship. With proper and effective lean production system philosophy in place, this can be avoided and organization can continue to sail through smooth and calm waters.

Summary

  • Hardware solutions

Hardware Solutions for the Critical Section Problem

In this section, we discuss some simple hardware (CPU) instructions that can be used to provide synchronization between processes and are available on many systems.
The critical section problem can be solved simply in a uniprocessor environment if we could forbid interrupts to occur while a shared variable is being modified. In this manner, we could be sure that the current sequence of instructions would be run, so no unexpected modifications could be made to the shared variable.
