6TUJUANThe purpose of an MRP system is to reduce the cash needed by a manufacturing organization. This increases the organization's return on investment, directly making the manufacturer a more profitable, atractive invesment.
7In a classical manufacturing organization, huge amounts of cash are tied up in in-process inventory, parts, that must be assembled and then sold. MRP uses planning and management to reduce this cash to the minimum.
8The basic idea is simple The basic idea is simple. A sales or marketing group estimates how many products it will sell at a future time. The MRP software back-dates using the factory's estimated time to assemble each product. Then, the system explodes the product into lists of parts needed, using the bills of materials developed by Engineering. The parts are ordered at times back-dated from the assembly dates. Finally, the cash flow of the above ordering, assembly, ship and payment process is developed.
9The system provides reports about which parts are needed to ship an order. If a high-value order is waiting for a few cheap parts, the planner can ask for the parts to be flow in by air-freight, and usually this will improve profits and return on investment.
