An Experimental Investigation of Priority Assignment in a Job Shop

Richard Walter Conway

ResearchPublished 1964

A study of priority disciplines in a queueing network model for a simplified job-shop process, which, in turn, is relevant for any situation having a set of different facilities and a sequence of tasks consecutively requiring the services of one or more of these facilities. The investigation employs Monte Carlo simulation on a digital computer to compare and evaluate a large number of priority disciplines. Both performance measures of inventory are considered: (1) number of jobs in the system and their work-content; (2) measures of individual job progress — time in shop and lateness against assigned due-date. The study principally concerns a discipline in which, at each point of decision, the available job with the shortest processing time is chosen.
