基于SPA的低等级公路路线方案评价

Low-grade Highway Schemes Evaluation and Optimization Method

考虑到影响低等级公路选线的主要影响因素,建立路线方案优劣评价指标体系,结合模糊熵理论与集对分析原理,建立公路路线方案的综合评价模型,利用信息熵理论获取各影响因素的权重,应用集对分析理论获取各评价指标对应于各评价等级的联系度,结合权重与各单指标联系度得出路线方案综合联系度向量,根据集对势原则得到低等级公路各路线方案评价等级。应用实例论证模型合理性,得出最优路线选择方案。

Taking into account the main factors affecting low-grade highway route, the rout e plan to establish the merits of the evaluation index system, combining fuzzy entropy theory and set pair analysis theory, establish a comprehensive program evaluation model road routes, access to each factor using information entropy theory weights, application of set pair analysis theory to obtain each index corre- sponding to each evaluation level contact degree, combined weight with the single index Contact degrees draw line program integrated connection degree vector, according to the set of potential principles are each course program evaluation low-grade roads level. Application examples demonstrate the rationality of the model and the optimal route options.
