...Problem description The CLSC network, considered by Kannan et al. (2009) for both of its cases, is detailed below. The network has K manufacturers catering to the needs of W retailers through a set of J distributors and I wholesalers. Manufacturers produce a set of products M! {m1,m2, . . . ,mp}. Raw material for producing product set M is purchased from the best supplier considered among S suppliers. Retailers’ demand for products M in each time period z! {1, 2, . . . ,Z} is known. Customers’ return is aggregated at C collection centres. The return quantity is known. The products are subsequently returned to the manufacturers for recycling. It is assumed that all the returned items are recycled and there is no disposal at the collection centres. The task is to analyse a multi-product, multi-period allocation problem for closed-loop supply chain networks (assumption of the model of Kannan et al. (2009))....
