| 摘 要： 政府投资项目在我国的社会主义经济建设中发挥着举足轻重的作用，2004年7月颁布的《国务院关于投资体制改革的决定》明确指出：在政府投资工程中推行代建制管理。文中针对代建制在政府投资建设项目中的广泛运用前景以及国内建筑市场的信用危机问题，从政府立场构建了一套代建人信用评价指标体系，并采用基于改进的TOPSIS多属性群体决策模型进行综合评判。评价模型中Minkowski距离和灰色数的引入，克服了传统TOPSIS模型综合评价过程中扩大权重影响和信息不确定的问题，并通过多位专家进行群体决策，使评价结果更符合客观实际。文章最后的实例验证，证实了模型在代建人信用评价问题的可操作性。 |

| Abstract: Government investment projects play a pivotal role in socialist economic construction, 《Decision of State Department on Reform of Investment system》clearly indicates the implementation construction-agent system in government investment projects. Based on the fact that construction-agent system will be widely applied in government investment projects in the future, and credit crisis problems in domestic construction market, a credit evaluation index system of construction-agency is established in this paper on behalf of the government, and the utilization of the improved multi-attribute group decision based on TOPSIS to judge as well. In the model, we both adopt the Minkowski distance and grey number operations, which may solve the over-weighted problem in the original TOPSIS model and the problem of uncertain information effectively, and making decision by experts group to make assessment can result more in line with objective reality. Finally, a representative case illuminates the application of the model, which pictures the calculation procedures and verifies the operability of the model. |
