Equipment Level Control,. The timespan encompassed at the higher levels has also gradually decreased, so that the time bucket of perhaps a week at the MPS I level, has been reduced to a matter of minutes or seconds at the cell and equipment levels.

The interrelationships between jobs flowing through the manufacturing systems leads to a tremendously intricate combinatorial problem. The traditional approach that has met with some success has been to break down the problem into a hierarchy of levels.

The determination of effective planning and control can be a very time consuming and difficult process. When dealing with an automated manufacturing system, there are a number of factors which make production planning and control problems even more complex.

Introduction,Rapid improvements in both computer hardware and software have made possible a dramatic shift towards automated manufacture. Complete mini factories can now operate with limited human involvement; such automated manufacturing systems rely on effective control procedures for their operation.

Cell Level Control,The previous chapters have given a description of the planning and control hierarchy (Chapter 4), a background to the factory level (Chapter 5) and the shop level (Chapter 6). This chapter describes cell level control, which is beneath the shop level in the hierarchy of planning and control.
