Operator-Based Capacity Control of Job Shop Manufacturing Systems with RMTs

Capacity adjustment by using reconfiguration machine tools (RMTs) is one approach to deal with customers rapidly changing demands. However, disturbances (e.g. rushed orders and machine broke down) and delays (e.g. transportation delay and reconfiguration delay) are great challenge for the manufacturers. In order to deal with these problems, we propose an operator-based robust right coprime factorization (RRCF) method to improve the capacity control process of job shop systems. We illustrate the applicability of this approach by simulation results of a four-workstation job shop system are given to support the efficiency of the proposed method.
