A Parameter-perturbation Approach to Replanning Operations

Abstract

In this chapter, we present operational and planning models for manufacturing systems. These models are developed to show the operational fidelity of the models to various manufacturing processes. The models are initially used to plan production activities for a variety of products that will be semi-automatically manufactured. The same models are then used to show how optimal operational conditions can be developed for a variety of processes (minimum time and cost). The models are then extended to show how the operating conditions can be perturbed so that optimal short-term planning models can be developed. The approach is illustrated using a family of product family models developed at Penn State University. The Factory for Advanced Manufacturing Engineering (FAME) at Penn State, a sophisticated manufacturing system is used to produce the products in volume, as would be the case for many commercial products.
