降低企业技术创新风险是提高企业技术创新绩效的关键.首先以技术创新六阶段模型为基础,针对技术创新的全生命周期识别了 18 项潜在风险.之后基于区间值直觉模糊集构建了应用于企业技术创新风险评价的模糊失效模式与影响分析 (failuremode and effect analysis, FMEA) 方法.该方法利用区间值直觉模糊集来评价技术创新各潜在风险的严重度、发生度和检测度,通过基于逼近理想解排序法 (technique for order preference bysimilarity to ideal solution,TOPSIS) 的非线性规划模型获得风险优先级并进行排序,以此为依据确定潜在风险的优先处理次序.最后以 D 公司的座椅开发项目为例, 验证了该模糊 FMEA 方法的可行性.

Reducing the risks of technological innovation in enterprises is the key to improving the technological innovation performance. This paper first identifies 18 potential risks based on the six-stage model of technological innovation, and then constructs the fuzzy failure mode and effect analysis (FMEA) method applied to the risk assessment of technological innovation based on the interval value intuitionistic fuzzy set. The method evaluates the severity, occurrence and detection of each potential risk by the interval valued intuitionistic fuzzy set. Risk priority numbers are obtained and sorted by the technique for order preference by similarity to ideal solution (TOPSIS)-based nonlinear programming solution, which can be used as a basis for prioritizing potential risks. At last, the feasibility of the fuzzy FMEA method is verified by an example of D-company's seat development project.
