Abstract: The existing research did not consider the relationship between supply chain risk factors,the relationship between risk factors and risk treatment methods under fuzzy environment.Therefore,the supply chain risk management approach based on the hesitant fuzzy Decision—Making and Trial Evaluation Laboratory (DEMATEL) and house of risk was proposed.The hesitant fuzzy sets were used to express the semantic evaluation with multiple optional membership functions to deal with the fuzziness of supply chain risk management.The hesitant fuzzy DEMATEL was developed to analyze the correlation between supply chain risk factors and determine the importance of risk factors.Then,the hesitant fuzzy house of risk model was proposed to translate risk factors into risk events and risk treatment methods.Based on the transformation relationships built in hesitant fuzzy house of risk model and the importance weights of risk factors obtained from hesitant fuzzy DEMATEL,the priorities of risk treatment methods were determined.A case study of supply chain risk management for a large fertilizer company was presented to illustrate the effectiveness of the proposed method.

Key words: supply chain risk, risk treatment method, hesitant fuzzy set, decision-making and trial evaluation laboratory, house of risk
