Abstract In spite of the increasing awareness apparent in the previous studies regarding the evaluation suppliers considering sustainability aspects, there are limitations on the incorporation of sustainable performance in terms of traditional, green and social aspects in supplier selection and order allocation. This paper presents the development of an integrated fuzzy TOPSIS-possibilistic multi objectives model to (1) solve a two-stage sustainable supplier selection problem; and (2) allocate the optimal flow of products quantity that should be ordered from suppliers towards the minimization of expected costs, environmental impact and travel time and maximization of social impact. Suppliers’ sustainable performance was based on traditional, green and social criteria, and quantified by using fuzzy TOPSIS and then integrated into the possibilistic multi objective model. The latter helps decision makers in having an order allocation plan that considers sustainability aspect. Furthermore, the multi-objective optimization model was re-developed as a possibilistic multi-objective optimization model (PMOOM) to handle the dynamic nature in some of the input data. Next, the LP-metrics method was employed to derive Pareto solutions out of the PMOOM. The quality of the obtained Pareto solutions was evaluated using the global criterion approach aiming to help decision makers in selecting the final Pareto solution. The applicability of the developed integrated fuzzy TOPSIS-possibilistic multi-objective approach was proven with sensitivity analysis on a case study of a meat supply chain.

1 Introduction Supply chain management includes all the operations related to the flow of merchandises from the point of origin (e.g., suppliers) to the end point (e.g., customers) (Lee et al. 2013). It generally helps in planning, implementing and controlling supply chain activities * A. Mohammed [email protected] 1

efficiently (Stevens 1990). Boran et al. (2009) argued that supply chain management aims at decreasing production risks and production costs, increasing total income, managing inventory levels, fulfilling customer demands and business activities and maintaining a successful business competitiveness. Supplier selection and order allocation is a main key factor in implementing a robust supply chain management (Mohammed et al. 2018a). This is based on the fact that firms depend more on suppliers to obtain a cost-effective pr
