服务外包风险评估是企业供应商管理的重要依据。传统风险评估方法 FMEA没有考虑风险模式间的相互影响关系,模糊DEMATEL方法用来分析风险模式的净影响度,进而修正其初始评估的严重度。针对传统FMEA方法将风险因子简单相乘的缺陷,采用模糊VIKOR方法对风险模式的严重度、发生频率和难检度进行综合评估。传统模糊VIKOR计算过程中需要进行模糊数的反模糊化处理,造成信息的损失,相对偏好关系分析引入模糊VIKOR计算解决这一问题。以某公司服务外包风险评估为例,验证了所提方法的有效性。
Service outsourcing risk assessment is an important basis for enterprise supplier management. The traditional risk assessment method FMEA does not consider the interaction between risk modes. The fuzzy DEMATEL method is used to analyze the net impact of risk model and then correct the severity of initial assessment. Aiming at the defect that the traditional FMEA method multiplies the risk factors simply, the fuzzy VIKOR method is used to evaluate the severity, frequency and degree of risk of the risk model. The traditional fuzzy VIKOR calculation process need fuzzy number of anti-fuzzy processing, resulting in the loss of information, the relative preference relationship analysis introduced fuzzy VIKOR calculation to solve this problem. Taking a company service outsourcing risk assessment as an example, the validity of the proposed method is verified.
