A KIND OF BOM-BASED MODEL FOR THE STOCK FORECAST AND CONTROL

摘要

The validity of the Order-Point-System is determined by the continuity and stability of the material requirements, but neither the required time nor quantity of the materials is steady but intermittent because of the variable requirements of the clients, which limits the application of the Order-Point-System. The MRP-System realize the aim of "at the right time, at the right place, get the right materials", that is the aim of "3R", however, the complexity of the system itself also restricts it's application and popularization, especially, it is difficult to apply in the Small&Middle Enterprises. In this paper, we present, for the first time, a kind of BOM-based model for the stock forecast and a kind of effective purchase strategy as also. This model overcomes the limitations of the Order-Point-System and MRP-System, at the same time, it inherits the qualities of the latter and now it is successfully applied in the Stock&Production-System of an enterprise. It's proved that the system based on this model is superior to MRP on the aspects of real-time capability, flexibility and facility.
