Priority Scheduling and Inventory Control in Job Lot Manufacturing Systems

Abstract This paper examines the relationship between the problems of priority scheduling and inventory control and describes several priority scheduling rules that use inventory information in making machine scheduling decisions. These rules include: Minimum Slack Time Per Remaining Operation? Critical Ratio, and a modification of the Shortest Processing Time Rule. Simulation experiments evaluate the gain in shop and inventory performance resulting from the inclusion of inventory data in scheduling rules. The results indicate that an increase in the timeliness of inventory information for scheduling purposes may not lead to improved performance.
