Optimization is an effective technique for improving the performance of chemical production process system which is a typical complex system. The model is complicated and the traditional method is difficult to optimize the object. So, an improved particle swarm optimization algorithm is used to optimize chemical process. When the population falls into local optimum, it carries out Gaussian mutation...
The flowshop scheduling problem with fuzzy processing times is concerned in this paper. A triangular fuzzy number is used to represent the uncertainty processing times of jobs. The due windows have been assigned to all jobs. If a job is completed within its due window, then it incurs no scheduling cost. Otherwise, an earliness or tardiness cost is incurred. The objective is to find a job schedule...
