结合能耗成本的双资源混合流程生产多目标调度优化研究

Energy consumption takes a big portion of the total costs of manufacturing companies and it is also one of main reasons to environment pollution. With the control requirements of energy consumption, production scheduling in manufacturing systems are highly important and complicated. This project is to study the optimization of production scheduling problem in the hybrid flow-shop environment with dual resources and with the considering of energy consumption cost, by employing various techniques including mathematical programming, multi-objective optimization and artificial intelligence based algorithms. The core research contents include: (1) the project is to study the integration optimization model of hybrid flow-shop production scheduling problem with dual resources coupling and the energy consumption cost. After clarifying the key objectives and constraints of the problem, the multiple-objective integrated mathematical model will be developed, based on which, the analytical analysis of the model will be further conducted. (2) The inherent feature of the mathematical model and the set-partitioning reformulation will be analyzed. Then, the project is to study the optimization solving methods of integrated scheduling problem with the branch and bound, and the branch and price algorithm. (3) For large scale problems, the project is to develop meta-heuristic methods with the multi-objective tabu search algorithm in which the multi-path search and the idea of pareto optimization are integrated. Moreover, the effectiveness and efficiency of method will be analyzed through practical data from industry and experimental simulation. The study of the project is quite helpful for model building, the theory of optimization and systematic solutions to the integrated optimization problem of production scheduling and energy consumption cost with the consideration of dual resources coupling. It is, to some extent, can also deepen the theory of production scheduling and can also guide potential practical applications. Meanwhile, the study of the project is supposed to improve the utilization of the manufacturing resources and improve the energy effective manufacturing, which in turn can give some insights for better operational decisions in production systems.
