熵权法在大型地下洞室群施工方案选优中的运用

通过分析熵权法及模糊综合评价法原理,将两个方法结合,避免了人为赋权值的不确定性造成的误差。并结合具体工程实例,将上述方法运用于某地下洞室群施工方案比选中。通过引用文献[3]中原始数据,且考虑比文献[3]中影响施工进度更多的指标,计算各个方案的综合评价值,得出的最终方案优选顺序与文献[3]稍有差别,但最优方案一致,且较文献[3]得出的最优方案辨识度更高,能够为施工决策者提供更切合实际的施工方案选优依据。

Entropy Method in Scheme Selection of Construction of Large Underground Cavern Group

By analyzing the principle of entropy method and fuzzy comprehensive evaluation method, combine the two methods, avoid the error caused by human and the uncertainty of the weighting, and combining with concrete project example, the methods above are used in construction of underground cavern group scheme is selected. By reference [ 3 ] in the raw data, and the effect than the literature [ 3 ] is considered more indicators, construction schedule, a calculation scheme of the comprehensive evaluation value, the optimization of the sequence and the literature [ 3 ] is a little difference. But the optimal scheme is consistent, and the literature [ 3 ] concluded that the optimal scheme of identification degree is higher, can provide more realistic decision makers for construction construction scheme selection basis.
