摘要
采用改进的熵权法对防波堤堤型设计方案中的质量、投资、工期、安全4个目标为指标进行客观权重求解,结合指数标度的AHP得出的权重构成设计方案的综合权重。采用AHP对递阶层次结构模型中各层次因素的相对重要性进行合理的量化分析,最终确定相对于目标层的重要性次序。结果表明,混合式防波堤的堤型设计方案最佳。
The improved entropy weight method is used for solving the objective weight of quality,investment,time limit,safety in breakwaters design scheme.The comprehensive weights are constituted with weights calculated by index scale AHP.Reasonable quantitative analysis of relative importance of all factors in hierarchical structure model is carried out by AHP.The order of importance relative to the target layer is ultimately determined.The results show that the composite breakwater design scheme is the best.
