PURPOSE/SIGNIFICANCE: In the past many years, some scholars have studied bid evaluation experts, such as the behavior of bid evaluation experts. However, previous research ignores the performance and competency of bid evaluation experts, so this paper aims to provide a theoretical basis for incentive and constraint mechanism and hierarchical or dynamic management of bid evaluation experts by implementing performance and dynamic competency evaluation of bid evaluation experts.
METHOD/PROCESS: Firstly, the evaluation index system of performance and dynamic competency of bid evaluation experts is preliminarily constructed by referring to relevant literature, and then the constructed evaluation index was modified and improved by consulting relevant stakeholders' experts. Secondly, considering the hesitation and consistency of expert weighting, the calculation method of expert weight coefficient and index score interval number is improved. Based on the theory of weight interval number, the corresponding mathematical optimization model is constructed to calculate the index weight according to the purpose of performance judgment and dynamic competency clustering of bid evaluation experts. Finally, the data of performance and dynamic competency of bid evaluation experts is obtained by questionnaire survey, and the empirical analysis was carried out by simulating the bid evaluation experts consistent with the actual situation.
RESULTS/CONCLUSION: After improving the calculation method of index score interval number, and then calculating index weight interval number through index score interval number, the length of index weight interval number can be decreased and the calculation accuracy of index weight interval number can be increased. In addition, the index weight calculated by the constructed mathematical optimization model can make the intra-class discrimination smaller and the inter-class discrimination larger. Finally, some suggestions are also provided for the management of bid evaluation experts.
目的/意义：在过去的许多年里，一些学者研究了投标评估专家，例如投标评估专家的行为。然而，之前的研究忽略了投标评估专家的表现和能力，因此，本文旨在通过对投标评估专家的表现和动态能力进行评估，为投标评估专家的激励约束机制和分层或动态管理提供理论依据。
方法/过程：首先，通过参考相关文献，初步构建了投标评估专家表现和动态能力的评价指标体系，然后通过咨询相关利益相关者的专家对构建的评价指标进行修改和完善。其次，考虑到专家权重的犹豫和一致性，改进了专家权重系数和指标得分区间数的计算方法。基于区间数权重理论，构建了相应的数学优化模型，根据投标评估专家的表现判断和动态能力聚类目的，计算指标权重。最后，通过问卷调查获得投标评估专家的表现和动态能力数据，并通过模拟与实际情况相符的投标评估专家进行实证分析。
结果/结论：改进了区间数指标得分的计算方法，然后通过区间数指标得分计算区间数指标权重，可减小指标权重区间数的长度，提高指标权重区间数的计算精度。此外，构建的数学优化模型计算出的指标权重可使类内差异更小，类间差异更大。最后，还为投标评估专家的管理提供了一些建议。
