改进灰色关联度定权在城市桥梁设计方案中的应用

在城市桥梁方案设计过程中,由于需要考虑的因素较多,导致最佳方案的选择具有一定的难度.因此,不少学者提出采用综合评价法(如模糊评价、神经网络和突变理论等)来评选最佳方案,从而降低评选的难度.而在综合评价法中,权重的计算是影响评价结果的关键因素.通过采用改进灰色关联度来确定权重,并结合实例与其他定权方法进行对比.结果表明,...

Application of Improving Gray Correlation for Deciding Weight in Design of Urban Bridge

The selection of the optimized scheme is certainly difficult in the course of the urban bridge scheme design because of many factors required to consider.Therefore,many scholars put forward the comprehensive evaluation,i.e.fuzzy evaluation,neural network and catastrophe theory to evaluate and select the optimized scheme so as to reduce the difficulty of selection.In the comprehensive evaluation,the calculation of the weight is key factor to affect the evaluation result.The article uses the improved gray cor...
