Global halal supply chain design, given the importance of the halal issue and the interest of Muslims and even non-Muslims alike, has become one of the most viable areas of research and application today. Moreover among the various industries, the food industry is one of the most important categories in the production of halal products. Therefore, this study presents a multi-objective model for an international four-level halal supply chain design for meat products that its objectives include budget objective, integration of products produced in the chain, utilization of each facility's maximum capacity, and ultimately environmental issues. Objective function includes the costs associated with traceability of products, meat, livestock, as well as the costs of obtaining and renewing halal certification for farms, slaughterhouses and factories. In order to select the candidate locations for slaughterhouses, the general and specialized criteria with data envelopment analysis approach is considered, then a mathematical model is developed considering the freshness of products and the uncertainty in cost and demand parameters. Finally, a robust optimization approach has been used to deal with the uncertainty of the input data and due to the multi-objective model, the Epsilon constrained evolution approach has been used to solve it. In order to validate the model and the solution approach, a case study in Iran has been researched and verified by simulation based on robust model. The test results show the profitability of the chain and can be introduced as a management tool for project finantial feasibility.
