| 中文摘要: |
| 应用可拓学的理论与方法，结合熵理论，建立了评标综合评价模型。根据评标评价物元指标体系，构建物元模型，并通过可拓学物元理论计算投标人评价指标的关联函数值，利用已确定的各物元指标熵权，得出各投标人的综合关联度，进而确定中标人。将指标评价由单一的确定值转变为区间值，从而能更全面地评价对象属于集合的程度，增强评标评价指标与综合评分值之间的关联程度，提高评价指标对评标结果的贡献度， 避免了主观判断投标人的弊端。 |
| 英文摘要: |
| Based on Extension theory and method, combined with entropy theory, a comprehensive bid evaluation model is established. An element model is set up based on evaluation matter element under evaluation index system, and through the extension element theory, associated bidder evaluation function value is calculated. Using the identified entropy of the matter element index, the comprehensive of all bidders correlation is obtained for determination of the winning bidder. This method evaluates by a range of index values instead of a single value, enabling a more comprehensive evaluation of the extent of the object belonging to the set, enhancing the contribution of comprehensive evaluation index score to the result of the bid evaluation to avoid the drawbacks of subjective judgments of bidders. |
