基于灰关联寻优的协同研制供应链风险评估研究

Research on supply chain risk assessment of collaborative development based on grey relational optimization

摘要:

研究不完全信息下大型客机协同研制供应链风险的评估方法。针对大型客机供应链风险评估的不完全特征,建立了考虑接近关联度和相似关联度最大的不完全信息推测模型；依据最大关联度的思想,提出了群体评估者定权的方法；基于灰靶决策框架,提出了考虑风险最大区分思想下的属性权重测算的极大熵方法。将所提出理论应用到大型客机“主-供”模式协同研制“初创期”的供应链风险评估实践,并得到合理的评估结果。

Abstract:

The evaluating method for the risk of the supply chain about the large aircraft under incomplete information is studied. According to the incomplete characteristics of large aircraft supply chain risk assessment, the incomplete information estimation model was established based on the close association degree and similarity with the greatest relevance. The weight method for the group decision maker is proposed based on the maximum correlation degree. Based on the grey target decision framework, the maximum entropy method for attribute weight calculation is proposed considering maximal risk distinguish. The proposed method is applied for the supply chain risk assessment of the stage of "main -supply" pattern, and the reasonable evaluation results are obtained.
