摘要
Based on the distinct characteristics of steel tube production process, the production plan and scheduling problem of seamless steel tubes is described as Multi-Objective Flexible Job-Shop Scheduling Problem. Considering the parallel machines of different capacities and speeds environments, maintenance of machines as well as inventory restriction, it is formulated as mixed-integer-programming model to decide the flexible routes for every job optimize the planning and scheduling, whose objective is not only to meet delivery date, but also to minimize transform cost and interruption in production. Given the problem is NP-hard, improved genetic algorithm is suggested, whose effectiveness can be well verified in scheduling decision support system for the production of seamless steel tubes of real company.
