柔性一体化炼钢炉次计划

基于面向柔性订单的生产模式,描述了一体化炼钢炉次计划问题,提出了广义柔性和狭义柔性,给出了一体化生产工艺规程,建立了多个单目标优化模型,通过罚函数法处理约束条件.引入和声搜索算法作为变邻域搜索算法的局部搜索策略,设计了新的混合算法.将基于柔性质量工件和基于刚性质量工件的两种问题进行了对比分析,从产能、无委材质量、有效产能及总附加操作成本角度出发,通过实例分析验证了模型和算法的有效性.

Flexible Integrated Charge Planning for Steel Making

Describing the problem of integrated charge planning for steel making production mode based on flexibility-oriented order, the generalized and restricted flexibility is defined conceptually and the integrated technological procedure is designed. With several single-objective optimization models developed and the restrictive conditions given through penalty function method, a new hybrid algorithm is designed introducing the harmony search algorithm as the local search strategy for the variable neighborhood search algorithm. The flexible and rigid requirements of steel weight are analyzed comparatively. In view of the throughput, steel weight without requirement, useful capacity and total incidental operation cost, the validity of the models and algorithms proposed is exemplified and verified.
