MRP definition
- The MRP is a stock planning and management system, based on computer support that answers the following questions: What, how much and when should it be manufactured (Unicen, 2003).
- It is a computer procedure to convert the master program for the production of final products into a more detailed program of raw material and components used in these products. The program indicates quantities of each item, when to replenish and when to deliver to ensure compliance with the master production program (Groover M., 1997, p. 993).

-
