建筑承包商信用评价是一个多指标决策问题，有效地对承包商进行信用评价能降低交易成本，约束和规范其行为，促进建筑市场健康稳定发展。针对目前建筑市场承包商信用缺失问题，考虑评价指标的特点，提出了基于DEA交叉评价和模糊综合评价相结合的承包商信用评价方法，采用DEA模型计算定量指标决策单元的平均交叉效率值并将其模糊化，同时利用三角模糊数加权平均算子将专家给出的定性指标的评价意见进行集结，最后通过算例计算了承包商的信用排序，验证了模型的有效性。

The assessment of contractors’ credit is a typical multi-indicator decision making problem. If assessed effectively, we can reduce the transaction cost and retrain their behavior. Therefore, they will behave normally, and in the end, to promote the construction industry to develop stably and healthily. As contractors are lack of credit at present, considering the features of indicators, a new credit evaluation method was proposed, which was based on DEA cross evaluation and fuzzy comprehensive assessment. We first calculated the average cross efficiency value of decision units’ quantitative indicators through the DEA model. Meanwhile, the qualitative indicators were got by the triangular fuzzy number weighted averaging operation. Finally, we ranked the contractors credit value through a numerical example, which verified the model we proposed is effective.
