摘要
Variables in the production environment inevitably result in deviations from the generated schedules. These variables affecting the system performance should be considered when dealing with dynamic dispatching problems. In addition, determination of the dispatching rules based on a single performance criterion cannot satisfy the requirements of different production performances. In this research, a dynamic dispatching strategy for multiple performance measures based on fuzzy inference is proposed. First, the variables affecting the system performance are identified. Then, the fuzzy membership functions and the fuzzy inference rules are established based on the simulation data. According to the statuses of environment variables, the fuzzy inference is performed to find an appropriate dispatching rule at each decision point to meet the best multiple performance measures. An example of the application is presented. The simulation results indicate that the proposed fuzzy-based dynamic dispatching strategy has a very good and robust performance.
