Abstract: In order to get the idea technological innovation scheme, the scheme selection is studied in the paper. From the actual situation, a group of evaluation index which included in the strength, the potential and the external environment about technical innovation scheme is selected. With the Vague set theory, the evaluation value of any innovation scheme is defined by the concept of Positive-ideal solution and Negative-ideal solution of TOPSIS. With the concept of distant in Vague set theory, a new evaluation method is built to get a satisfied solution. This method reflects the advantages of Vague set theory which describe the uncertainty, meanwhile, the basic criteria for project evaluation is meet by the TOPSIS idea. The idea and method not only take a new application field to the Vague set study, but also get a new idea and method to the technological innovation study.

Key words: management engineering, evaluation method, vague sets, technological innovation, TOPSIS

摘要： 为了得到理想的技术创新选择方案,论文从技术创新的实际出发,从实力、潜力和外部环境三个角度选择了一组反映技术创新项目实际情况的评价指标。并借助Vague集理论,通过TOPSIS中正负理想解的思想定义了任意创新方案的评价指标值,运用Vague集理论中距离的概念构建了新的评价方法,进而得到了满意的评价结果。该方法一方面体现了Vague集理论描述不确定性问题的优点,另一方面借助TOPSIS思想满足了方案评价的基本准则。这一思想和方法的提出不仅为Vague集理论研究提供了新的应用领域,也为技术创新的研究提供了新的思路和方法。
