基于区间数排序可能度法的施工方案评价方法研究

摘要

Construction program is a specific implementation plan with the comprehensive consideration of personnel,machinery, materials and engineering features. Reasonable evaluation of multiple construction programs can help ensure quality,time and cost of the project. A construction program evaluation model is built based on the basic principles of ranking interval numbers. Firstly,the program evaluation weight values are determined with the establishment of evaluation index. Secondly,according to the initial interval number matrix of the program given by experts,the comprehensive attribute values of programs are determined. Then, possibility degree matrix is developed and its ranking vector is determined based on the possibility degree method for ranking interval numbers so as to get the ranking relationship of construction program with possibility degree with the practical case.%施工方案是综合考虑人员、机械、材料和工程特点等有针对性地制定的工程施工的具体实施计划。对多个施工方案进行合理的评价与优选有利于施工企业保证工程质量、确保工程进度以及节约工程成本。运用区间数排序法的基本原理建立了施工方案评价模型。首先建立了施工方案评价指标并确定其权重值，在专家以区间数形式给出方案指标的初始矩阵基础上确定各方案的综合指标值，基于区间数排序的可能度法建立可能度矩阵并确定其排序向量，进而评价施工方案的优劣及其可能性程度，并结合实例进行了分析。
