A DECISION THEORY APPROACH TO PRIORITY DISPATCHING FOR JOB SHOP SCHEDULING

Abstract

Recent developments in the design of job shop scheduling systems have inspired a new approach to priority dispatching. The basis for the approach is in elementary decision theory: at each decision juncture define the alternative courses of action, evaluate the consequences of each alternative according to a given criterion, and choose the best alternative. The experimental results of a simulated single machine queueing system reinforce earlier findings that a decision theory approach represents a significant advance over conventional priority dispatching. © 1993 Production and Operations Management Society
