非线性关系下绿色施工管理多目标权衡研究

摘要

绿色施工管理除去工期、费用、质量三大目标外,还考虑环境影响、社会影响,形成了更全面、复杂的目标管理体系.分析了绿色施工管理各单项工作综合费用、质量、环保水平、安全指数与持续时间之间的非线性关系,利用多属性效用函数理论及最优化理论,构建了非线性关系下的绿色施工管理多目标权衡模型.采用遗传算法求解,求得的最满意解为绿色施工管理的各目标控制要求.最后应用实例验证了模型的合理性,并讨论了实现绿色施工管理的一个困境.%Except the duration, the cost and the quality of the three goals, the green construction also consider the environmental impact and the social impact.A more comprehensive and complex target management system is formed.This paper analyzed the non-linear relationship between the comprehensive cost, quality, environmental protection level, safety index and duration of green construction management.And based on the multi-attribute utility function theory and the optimization theory, a multi-objective trade-off model of green construction management under nonlinear relation is constructed.Using the genetic algorithm to solve, the most satisfactory solution are the target control requirements of the green construction management.The rationality of the model is demonstrated by an example.And the dilemma of realizing green construction management is discussed.
