摘要
由于现阶段对资源的均衡操作大都侧重于对工期-资源同时优化,很少涉及质量和成本,所以这里提出了一个两阶段优化模型,第一阶段是基于工期、质量和成本三个目标为非线性关系,建立三个目标的综合优化模型;第二阶段是从上阶段对所得到的非劣解中由决策者选择一个或多个满意的解输入到本阶段进行资源均衡优化,两阶段均用遗传算法求解,最后通过一个实例证明了两阶段模型的可行性与优越性.
As most of the way of resource leveling is focused on time-resource trade off,very little is involved in the quality and cost,a two-stage optimization model is proposed：synthesis optimization models is established based on the relationship of the time,the quality.The cost is the misalignment,and it uses chromosomes which are built up by mode to carry on the heredity operation.The second stage is to choose a non-poor solution obtained from the decision-maker from the first stage inputs to this stage to carriy on the resource leveling optimization.It takes time in resources variance minimum as the objective function,and the gene value which is non-critical process＇s beginning time to make up the chromosome to carry on the heredity operation.An application example is analyzed to illustrate the use of the model and demonstrate its capabilities in generating and visualizing optimal tradeoffs during construction time,cost,quality,and resource.
