How does CBN work?
Method at the heart of MRP – Manufacturing Resource Planning, the calculation of net needs or CBN allows from the raw needs in finished products determined with the PDP, to determine the proposed orders: manufacturing launches. or forecast supplies.
the CBN is based on the gross finished product requirements determined with the PDP to determine the proposed orders. Thus, it is with the Calculation of Net Requirements that we define the production launch orders and/or the supplies.
The MRP calculation is only performed for items that are not PDP items. The purpose of the MRP calculation is to generate formal plans in phases, by item, in order to supply the right item, at the right time, in the right place, and in the right quantity.
Gradually, and with technological development, MRP1 extends to the management of other production resources (machines, labor, stocks, cost calculation, etc.). It then becomes a real tool for calculating the net requirements for components and the capacity of production resources.
The PDP calculation is used for finished items that have forecasts or a sales order line. These items are called “PDP items” and are dynamically identified at the start of the calculation. The MRP calculation is the calculation of material requirements based on the actual demand for components and the demand forecast at the component level.
The principle of MRP MRP (Material Requirements Planning) is a method of production management which consists of calculating the net milestone requirements.
