JIT production is a production scheduling system components or products on time, quality, and in accordance with the required amount by the next production stage or in accordance with customer demand.
JIT production can reduce the time and cost of production by:
1. Reduce or eliminate work in process in each workstation (work station) or the stages of product processing (the concept of zero inventory).
2. Reducing or eliminating “Lead Time” (waiting time) of production (the concept of zero wait time).
3. Continuously pushing hard to reduce machine setup costs at each stage of processing products (workstation).
4. Emphasis on the simplification of processing the product so that activities are not value-added production can be eliminated.
