Long-term capacity management: Linking the perspectives from manufacturing strategy and sales and operations planning

E$cient long-term capacity management is vital to any manufacturing "rm. It has implications on competitive performance in terms of cost, delivery speed, dependability and #exibility. In a manufacturing strategy, capacity is a structural decision category, dealing with dynamic capacity expansion and reduction relative to the long-term changes in demand levels. Sales and operations planning (S&OP) is the long-term planning of production levels relative to sales within the framework of a manufacturing planning and control system. Within the S&OP, resource planning is used for determining the appropriate capacity levels in order to support the production plan. Manufacturing strategy and sales and operations planning provide two perspectives on long-term capacity management, raising and treating di!erent issues. In this paper, we compare and link them in a framework for long-term capacity management. ( 2001 Elsevier Science B.V. All rights reserved.
