仿真在造船企业管子生产物流系统中的应用

以某造船企业管子分厂产能评估为应用背景,针对生产过程为多班制、多工艺、多工序、混合作业的复杂生产方式,将生产物流仿真系统分为输入层、仿真层、输出层三个层次,采用面向对象的仿真技术,把管子生产物流中的各种要素分为不同的类,构建了管子生产物流系统的仿真模型.并对管子分厂生产能力在不同工况条件下,在不同生产调度策略下分别进行了评估.通过仿真评估帮助决策者制定出最佳的决策,提高生产能力.     

A Heuristic Method for Two-sided Assembly Line Balancing Problem

A two-sided assembly line is typically found in plants producing large-sized products. Its advantages over a one-sided line and the difficulties faced in two-sided line balancing problems were discussed. A mathematical model for two-ALB problem was suggested. A modification of the “ranked positional weight” method, namely two-ALB RPW for two-ALB problems was developed. Experiments were carried out to verify the performance of the proposed method and the results show that it is effective in solving two-sided assembly line balancing problems.
