Cover-Time Planning,An alternative to Material Requirements Planning;with Customer Order Production Abilities and Restricted Work-In-Process
An alternative to the more commonly known Material Requirements Planning (MRP) is presented. The technique is based on a coverage analysis and is called Cover-Time Planning (CTP); CTP is in fact a reorder-point system, but with time instead of quantity as the decision variable. Similar to Kanban CTP restricts the total amount of an item but in the CONWIP way, not in every machine, but the total amount in stock and in the route from its components. Contrary to traditional reorder-point systems CTP uses the information in the bills of material to present forecasts for all possible component items. CTP shows inherent priority numbers and like MRP CTP makes it possible to estimate future work load. The main principle behind CTP is to wait as long as possible before production starts; to wait so that it is more exactly known what the customer asks for and by that avoid to tie up material and components in something that the customer will not ask for.
