对于BOT项目委托方而言，项目的价值在于社会效益的实现程度而不仅仅是考虑项目的建设成本。提出了一套考虑社会成本的BOT项目特许经营者评标属性集，当特许经营者评标属性的权重已知，评标委员会对各属性的评价以及业主对特许经营者的偏好不确定的情况下，运用区间数和灰色关联分析来构建特许经营者评标模型，通过引入区间数距离，求得区间数的灰色关联度，最终对各候选特许经营者进行排序。由于该模型考虑了社会成本因素，对促使特许经营者更加合理地规划项目方案，减少社会成本的形成具有一定的作用。此外，引入区间数来处理社会成本等模糊评价信息，提高了评标结果的科学性。

For BOT project clients,the project value is to realize social benefit,rather than merely to consider the construction cost of the project. This paper presents a set of social-cost-based attributes for bid evaluation of BOT project concession candidates. The bid evaluation committee can develop a model for bid evaluation of concession candidates based on interval numbers and grey relational analysis,if they understand weighted attributes and face uncertainties concerning the attributes evaluation and the owner’s preference for concession candidates. The ranking of concession candidates can be done by obtaining grey correlation for interval numbers through the distance between interval numbers. This social-cost-based model is established to contribute to less social costs by forcing a concession candidate to work out a more reasonable operational scheme. Meanwhile,uncertain information for decision making is offset by interval numbers,yielding more practical evaluation results.
