摘要
针对直觉模糊信息多属性决策中存在的问题,提出一种基于优化理论的多属性决策方法.该方法首先按照方案的属性类别确定直觉模糊“理想方案”和“负理想方案”,然后计算各方案与“理想方案”和“负理想方案”的距离,运用扩展的最小二乘方准则构造目标函数求解,建立了直觉模糊信息多属性优化决策模型.最后,通过黄河下游公路大桥超深大直径钻孔灌注桩成孔工艺优化实例进行了计算分析,得到的结果与施工单位原定的方案相符.
For the problems existing in multi-attribute decision making with intuitive fuzzy information,a multi-attribute decision making method based on optimization theory is proposed.The method first determines the intuitive fuzzy"ideal scheme"and the"negative ideal scheme"according to the attribute category of the scheme,then calculates the distance from the"ideal scheme"and"negative ideal scheme",constructs the objective function using the extended least squares criterion,and establishes an optimal model for multi-attribute decision with intuitive fuzzy information.Finally,the optimization of the Ultra-deep,largediameter bored in Highway Bridge of the Lower Yellow River is analyzed and the results obtained are consistent with that planned by the construction unit.
