The main feature of sustainable supply Chain Management is reuse end life (EOL) products to reduce the environmental pollution. This paper considers consignment stock (CS) policy for a closed-loop chain (CLSC). To achieve economic goal, this study presents multi-echelon with single manufacturer, retailer and third-party service provider. objective optimize three-level CLSC under Stackelberg game scenario. other identify impact remanufacturing EOL products. In CLSC, manufacturer acts as leader retailer, third party are followers. Under manufacturer’s leadership, acquire three different decision strategies – I, II, III. strategy follower, whereas in they obtain Nash strategy. III, act one unit decide their decisions centrally. Numerical example sensitivity analysis used illustrate optimal results also check behaviour key model-parameters. best outcomes found I. findings our show that when upper level player has more power then gives outcomes.
