Dynamic group job shop scheduling

摘要

This paper presents a dynamic Pareto-optimal method for flexible job shop scheduling based on two criteria simultaneously: the relative manufacturing cost criterion and the average orders utility criterion. Group scheduling for a given set of jobs with due dates that are typical for a 'make-to-order' strategy is considered. In this method the concept of production intensity as a dynamic production process parameter is used. A software package allows scheduling for a medium quantity of jobs. The result of software application is the set of non-dominant versions proposed to a user for making a final choice.
