A Method of Execution Time Adjustment in Parallel Projects Based on Critical Path Analysis

Abstract

It becomes very important that the potential delays in the delivery dates are estimated as early as possible and the adjustments to the production periods are applied as little as possible only to the higher priority items in order to maximize the effectiveness. However, just like planning the most optimized schedules on the job shop production floors, quantitative decision making on load change actions has been a very difficult problem. Thus, in order to solve such problems, we have proposed CSM (Concurrent Scheduling Method) as a means to plan schedules. Under CSM, the optimum schedule is planned to maintain the delivery dates while solving resource conflicts. In this article, a new technique is proposed in order to adjust production periods of projects (to be called as concurrent projects, hereafter), which share resources and are processed concurrently by investigating the established critical paths while a function is added to CSM.
