基于用户评价信息的动态综合评价——一种协同设计主体资源的评选方法

Dynamic comprehensive evaluation based on user comments:a method of collaborative design agent resource selection

针对基于用户评价信息的协同设计主体资源动态综合评价问题,在分析综合评价特点和要求的基础上,提出了一种反映设计主体资源综合能力本质的动态综合评价模型。该模型考虑了用户评价值所在时段与现在时段的接近程度以及增减变化趋势对动态评价值的影响,采用一种无需进行判断矩阵一致性检验的AHP改进方法确定综合评价指标权重。实验验证表明,该动态模型体现了用户评价值的增减变化和时间价值变化等动态特性,反映了资源的优劣程度、稳健程度和增长程度,简化了指标权重系数的计算,解决了传统AHP方法在遇到因素众多、规模较大情况时,容易出现判断矩阵难以满足一致性要求等问题,实现了在大量评价指标和评价值动态变化情况下的综合决策。

Based on the analysis of characteristics and requirements of the dynamic evaluation of collaborative design agent resource, we presented a model of dynamic comprehensive evaluation which reflected the essential of comprehensive capabilities of the resource and was based on comments by users. We considered the influence of the aid-decrease changing trend and similarity from the time When users gave their evaluation to the current time, and used an improved analytic hierarchy process （AHP） that did not need to verify the judging matrix coherence or decide the evaluation indices weights. The experiment shows that the dynamic model＇ which embodies dynamic characteristics such as value changes in user evaluations and time, reflects the advantages, disadvantages, robustness and resource growth extent. Additionally, the dynamic model can simplify weightiness coefficients of the indices calculation, and solves the accordant problem of the judging matrix when there are too many indices in the AHP. The model enables the comprehensive decision-making when there are many indices and the evaluation value varies dynamically.
