Over the years, food supply chains (FSCs) have faced various challenges, including supply chain interruptions. Previous studies focused only on household food waste. In this study, the FSCs risks is connected with food wastage to develop sustainable framework to reduce food waste. A Pareto analysis is developed for risk identification based on feedback from 130 experts from food companies. Finally, a blended grey-based Decision-Making Trial and Evaluation Laboratory (DEMATEL) model has been proposed to assess the relationships among the identified major risks in FSCs. The five risks of greatest priority include: lack of skilled personnel, poor leadership, failure within the IT system, capacity, and poor customer relationship. The risk mitigation strategies for these risks are also presented. The proposed model is applied to food processing companies in Bangladesh to establish a sustainable business policy to minimize food wastage. These results can guide managers and practitioners to formulate resilient strategies to mitigate the identified risks, thereby minimizing food wastage and lead to food safety, security and sustainability across the food supply chain. The proposed model can be extended to address sustainability risk and be integrated to the internet of things for planning, monitoring, controlling, and optimizing supply chains in real time.

多年来，食品供应链（FSC）面临各种挑战，包括供应链中断。先前的研究仅集中在家庭食物浪费上。在这项研究中，FSC的风险与食物浪费有关，以建立可持续的框架以减少食物浪费。基于来自食品公司的130位专家的反馈，开发了帕累托分析以进行风险识别。最后，提出了一种基于灰色的混合决策试验和评估实验室（DEMATEL）模型，以评估FSC中已识别的主要风险之间的关系。最优先考虑的五种风险包括：缺乏熟练的人员，糟糕的领导能力，IT系统内的故障，容量以及不良的客户关系。还介绍了针对这些风险的风险缓解策略。提议的模型适用于孟加拉国的食品加工公司，以建立可持续的商业政策，以最大程度地减少食品浪费。这些结果可以指导管理人员和从业人员制定有针对性的战略，以减轻已识别的风险，从而最大程度地减少食品浪费，并在整个食品供应链中实现食品安全性，安全性和可持续性。可以将提出的模型扩展为解决可持续发展风险，并将其集成到物联网中以实时规划，监视，控制和优化供应链。食品供应链中的安全性和可持续性。可以将提出的模型扩展为解决可持续发展风险，并将其集成到物联网中以实时规划，监视，控制和优化供应链。食品供应链中的安全性和可持续性。可以将提出的模型扩展为解决可持续发展风险，并将其集成到物联网中以实时规划，监视，控制和优化供应链。
