Abstract: In this research, a dynamic evaluation method on better action conforming to natural rules considering twice identification of advantage is proposed to solve the individual advantage weight and laying more stress on the present information on the past problem in dynamic comprehensive evaluation. In this method, firstly, the weights of evaluated objects are calculated using the individual advantage identifying method from the theory of better action conforming to natural rules. Then, according to the identified results, the competitive advantage evaluation is set and the average information for each outcome is to make democratic advantage consequence. Furthermore, the democratic advantage result of the evaluated objects is calculated the second time by the method of individual identification, which outputs the dynamic individual weights of the evaluated objects. Moreover, the optimal bottom-up approach of dynamic competitive advantage evaluation and from top to bottom dynamic democratic advantage assessment are determined by establishing and solving the evaluation model. Finally, an example of the real situation is used to justify the proposed method for effectiveness and superiority.

Key words: competitive advantage evaluation, comprehensive evaluation, advantage identification, the second advantage

摘要： 针对动态综合评价中难以判别个性化优势和权重确定“重近轻远”的问题,提出了一种考虑二次优势判别的动态竞优评价方法。采用竞优理论中的个性化优势判别法确定客体的各指标权重;据此构建比较优势评价模型,对其各评价结果求解算术平均数,确定民主优势评价值;随后对民主优势评价结果进行二次个性化优势判别,并计算客体的动态个性化权重;进一步建立和求解动态的自下而上比较优势评价模型和自上而下的民主优势评价结果。此外,以一个应用算例来验证该方法的有效性和优越性。
