基于多目标优化的施工机械设备优化配置方法研究

Study on the optimal allocation method of construction machinery based on multi-objective optimization

工程施工系统是一个由各个作业环节组成的复杂系统。如果各作业环节中的施工机械设备配置不合理,就会延误施工工期,增加施工费用。通常所采用的基于灵敏度分析的施工机械设备优化配置方法不能自动寻优,需要人工对计算结果进行比较、分析,过程较繁琐,并且受人的主观影响。基于多目标优化的施工机械设备优化配置方法,使施工机械设备优化配置问题有了统一的评价目标、评价准则,实现了施工机械设备优化配置方案在程序设计中的自动搜索,提高了寻优的效率,具有广泛的应用价值。

The construction system is a complicated system that is composed of many activities If there is no reasonable machine equipment allocation in activities, the project completion time will be delayed and cost will be raised The method of sensitivity analysis based machine equipment optimization allocation, which is usually used, can't search automatically optimization results but need manually to compare and analyze the calculation results Such optimization process is complex Moreover, it is affected by man's subjectivity This paper presents an optimal allocation method of construction machinery based on multiobjective optimization, which makes the construction machinery optimization allocation have a unified evaluation goal and standards and realizes the automatic search function of construction machinery optimization allocation scheme, increasing the efficiency of searching optimization results The method has a wide application value
