A Proposal of a Job Shop Scheduling Method for Solving Resources Contention Problems and its Verification

Abstract

We propose CSM (Concurrent Scheduling Method) for the manufacturing site management in the job shop production. CSM aims to complete all the orders keeping the delivery date. In CSM, processing procedure is expressed in the CSM's Process-Chart similar to the PERT chart. The Process-Chart consists of Job-boxes and 2 kinds of Connectors, Connectors-in-the-order and Connectors-in-the-resources. Job-boxes and Connectors-in-the-order show a procedures of an order. Job-boxes and Connectors-in-the-resources show load orders of a resource. Using the Process-Charts, we can see huge information, changing hour by hour. A plan is made reflecting these information, and this plan achieves the flow of the best processing on the manufacturing site.
