基于仿真的室内装焊工场分段建造方案评估与优化

Evaluation and Optimization of Simulation Based Block Construction Scheme for Indoor Assembly in Welding Workshop

基于仿真的生产调度方法,以室内装焊工场的分段建造(含分段总组)为研究对象建立三维仿真模型,通过仿真模拟输出仿真运行数据,实现对特定建造方案下的物量、场地利用率及生产计划等参数的准确评估。针对建造方案中的不合理之处,通过采用基于序列的优化方法对生产计划及场地布局等进行优化。实例分析结果表明,该优化方法可缩短分段建造周期、提高场地利用率,从而为生产计划的制定和生产调度水平的提升提供支持。

This study establishes a 3D simulation model for the block construction (including section assembly) of indoor assembly in welding workshop based on the production scheduling simulation method. Accurate evaluation of production capacity, space utilization, production plan and other parameters for the specific construction can be achieved with the simulation data and the production plan and space arrangement are optimized with a sequence based optimization method to rectify the inappropriateness. The result of the analysis on some examples shows that the proposed optimization method can reduce the block construction cycle, increase space utilization, and thus provide support to the production plan making and to the improvement of production scheduling.
