A contribution in materials requirement planning techniques

الملخص EN

Materials requirement planning (MRP) is a widely used method for production planning and scheduling.

MRP module allows for more efficient and effective use of resources.

MRP is a method to determine what, when, and how much component and material are required to satisfy a production plan of end products over time.

A MRP system requires a great deal of information and processes in order to perform its complete logic.

Planning the menu and calculating the number of servers is equivalent to creating an authorized Master Production Schedule (MPS), while reviewing the recipes to assemble the raw materials is equivalent to checking The Bill of Material (BOM) file for the needed materials, so that MRP checks the inventory records for the materials on hand and those purchasing needs to procure.

In this paper, a computerized operations research techniques was used to model the required factors to optimize the use of MRP problems using a general computer programs named (WINQSB).

Inventory control lot sizing was used and modified in such a way that it minimizes the combination of setup cost, holding cost and work-in-process cost.

This proposed approach embeds an optimization routine.
