Sustainable partner selection and order allocation for strategic items: an integrated multi-stage decision-making model

Current environmental issues and government requirements, together with pressure from the market other stakeholders, emphasise importance of partner selection in constructing operating sustainable supply chains. Strategic items, which carry both high risk purchase, are particularly important This paper presents an integrated decision-making model, aims to solve order allocation problem for strategic items In proposed weightings different decision-makers first calculated using Trapezoidal Fuzzy Numbers. Then, Taguchi loss function is used evaluate relative potential partners, weighting results criteria by Best-Worst Method. Finally, considering weights Particle Swarm Optimisation (PSO) multi-objective programming problem, Technique Order Preference Similarity Ideal Solution (TOPSIS) applied identify most appropriate Pareto solution items. An illustrative application model undertaken a leading Chinese LED lighting manufacturer show its effectiveness applicability.
