In this chapter, we discuss essentials of the best-known manufacturing planning and control systems. Each of these systems has its merits but each one also requires a number of conditions to be fulfilled in order to perform near-optimally, often without being explicit about these conditions. The focus of this chapter will be on discrete manufacturing planning and control with limited attention to pro- cess industries. We begin the discussion at a basic level with the most elementary result of efficiency-driven production, the Economic Production Quantity, and an extension to non-stationary deterministic demand. Next, we continue with an intro- duction to Materials Requirements Planning (MRP) and Manufacturing Resources Planning (MRP II), followed by a discussion of capacity oriented Hierarchical Pro- duction Planning (HPP). On a more advanced level, we introduce an entirely different approach based on the adoption of the Just-in-Time (JIT) and Lean Manufacturing (LM) philosophies. JIT and LM are more than just other planning models; they propose an entirely different approach to organizing manufacturing and assembly processes. A case study on the Toyota production system helps to understand key concepts of Lean Manufacturing. We continue with the concepts of Workload Con- trol and the Theory of Constraints, which can be seen as means to keep internal lead times stable and hence predictable. Finally, we provide a glimpse on state-of -the-art and future developments, with a focus on digital and cloud manufacturing.

Abstract
In this chapter, we discuss essentials of the best-known manufacturing planning and control systems. Each of these systems has its merits but each one also requires a number of conditions to be fulfilled in order to perform near-optimally, often without being explicit about these conditions. The focus of this chapter will be on discrete manufacturing planning and control with limited attention to pro- cess industries. We begin the discussion at a basic level with the most elementary result of efficiency-driven production, the Economic Production Quantity, and an extension to non-stationary deterministic demand. Next, we continue with an intro- duction to Materials Requirements Planning (MRP) and Manufacturing Resources Planning (MRP II), followed by a discussion of capacity oriented Hierarchical Pro- duction Planning (HPP). On a more advanced level, we introduce an entirely different approach based on the adoption of the Just-in-Time (JIT) and Lean Manufacturing (LM) philosophies. JIT and LM are more than just other planning models; they propose an entirely different approach to organizing manufacturing and assembly processes. A case study on the Toyota production system helps to understand key concepts of Lean Manufacturing. We continue with the concepts of Workload Con- trol and the Theory of Constraints, which can be seen as means to keep internal lead times stable and hence predictable. Finally, we provide a glimpse on state-of -the-art and future developments, with a focus on digital and cloud manufacturing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
