Rating Supply Chain Risks Using the Combined Approach of FMEA Optimization and Gray Theory (Case Study: Mashhad Food Industry Units)

The ranking of supply chain risks using a combined approach is to optimize the method of analyzing failure factors and their effects and gray theory in Mashhad food industry units.

Due to its nature, the present research belongs to the category of descriptive-analytical researches, with qualitative variables, and from the point of view of the objective, it belongs to the category of applied researches. In this research, the risks in the supply chain of the food industry were first identified. In such a way that; first, the risks in the supply chain were identified through library studies and research literature, and then they were given to the experts using a fuzzy Delphi questionnaire to be rated by the Likert scale. Due to the time limitation and defects in the analysis as well as vague, incomplete and uncertain information data, these points became a gray area. Then, using the method of analysis of failure factors and its effects, the risk priority score number was calculated in order to investigate potential failure situations. In this way, the indicators and dimensions of supply chain risks were ranked with the number of the priority score of risk taking. Risks with a higher risk priority score have a higher risk tolerance and require more attention.

The result of scoring and calculations determined that the economic dimension has the highest risk in the supply chain. After the economic dimension, the legal, strategic, individual, political and natural dimensions are the second to the sixth, and the cultural and social dimensions are the seventh and the information dimension is the eighth.

Originality/Value:

 The findings of this research will help managers, considering the limited resources, for control and management, especially in conditions of uncertainty, by prioritizing the risks of their supply chain. According to the level of risk-taking of each, as well as considering preventive measures regarding these risks, to prevent possible irreparable and critical injuries.
