Abstract

Ranking supply chain risks is as an important part of supply chain risk management especially when the numbers of risk factors are increased. In this study, the comprehensive structure of the main risks are prepared in three levels of the supply chain (3 total sets, 7 sub-categories and 34 categories and 300 subcategories) initially and then these risks are evaluated and ranked in the steel supply chain in Esfahan Steel Complex as a case study. For this purpose, group decision-making methods and means of collection and aggregation experts and linear assignment method is used as a method of Multiple Decision Making to determine the ranking of risks. Ranking indexes were divided in two primary and secondary categories. The primary index is based on likelihood and impact of risks on the main objectives (schedule, cost, quality and scope) of supply chain activities with different weights. The second category of indicators includesocio-economic effects, environmental impacts, near the time of risk, exposure to risk, the confidence level of the estimates and the management of risk, risk reduction and risk discovering. Risks are ranked better using linear assignment method and according to various indices and are ranked more realistic. Based on the results, risks related to procurement and supplier are identified and introduced as the most critical risks.
