Abstract: To lower the complexity and improve the efficiency of multiobjective optimization for Flexible Job-shop Scheduling Problem (FJSP), an integrated optimization method for FJSP based on multiple rule machine assignment and job sequencing was proposed. A multiobjective optimization model for FJSP was established with the makespan, max load,total load and manufacturing cost. Aiming at the combinatorial explosion characteristics of the model, a new thought of integrated optimization combining the multiple rule machine assignment with job sequencing was presented to lower its complexity. To improve the computation efficiency, an object-oriented technique was put forward to deal with the data exchange between different entities. Based on Non-dominated Sorting Genetic Algorithm (NSGA Ⅱ) thought, a multiobjective optimization algorithm based on multiple rule machine assignment and job sequencing was proposed, and the effectiveness of the new scheduling method was validated by simulation experiments and application.

Key words: flexible Job-Shop scheduling, multiobjective optimization, multiple rule, object-oriented technique, improved NSGA Ⅱ
