Abstract: Abstract This paper addresses the three-dimensional concurrent engineering and presents an integrated mathematical model to determine design and production process of each part of product and its supply chain network with a sustainable approach. Demand is assumed to be design-dependent, and supply chain under study is closed-loop. From sustainability viewpoint, total profit in planning horizon is considered as economic index, and an approach based on life cycle assessment is implemented to calculate environmental index. In this approach, the eco-costs method is utilized to quantify life cycle environmental impact of activities. Also, a ratio based on job creation opportunity and employment rate is considered as social index. To show the performance of the proposed mathematical model, data for a home appliance producer from Iran is utilized. Eventually, a sensitivity analysis is presented to examine the effects of variations in demand on the resulted solutions and the values of triple objective functions.
