Abstract: In this paper, a sustainable supply chain (SSND) problem is developed which contains economic aspects, environmental issues, social impacts and customer service level. The economic objective is minimising total cost of the whole network (production, transportation, inventory holding/stock-out and investment). CO₂ emission is considered as environmental issue and the social objective is fixed job opportunities. The customer satisfaction objective contains lead time and stock-out ratio. All of the objectives are in contrast and there is a need for using multi-objective approaches for solving the problem. Normalised normal constraint method is used to capture trade-off between objectives. Simulated numerical examples are considered to evaluate the model and solution approach. Impact of some parameters on customer service level is analysed by sensitivity analysis. The results show that the proposed model performance is acceptable and it can prepare good managerial decisions for real cases by considering four aspects of business environments simultaneously.
