Abstract:

The goal of this report is to define a factory model and a set of experiments that can be used to compare alternative scheduling methods. The model was originally created to provide a comparative analysis of the OPIS and ISIS constraint directed scheduling systems and the COVERT dispatch rule. The model is a simplification of the model used originally to test ISIS. This report defines a Job Shop in terms of 1 Parts, including physical characteristics 2 Process plans composed of operations, precedence relations, and resource requirements 3 Resource descriptions, including labor machine ratios and 4 Constraints covering due dates, work in process, machine restrictions, etc. Twenty-two experiments are defined each containing orders composed of release dates, due dates, parts, quantity, and priority. Orders were statistically generated based on the parameters described in the latter sections.
