Many scholars have already investigated the location problem of
supply chain facilities and centres under different conditions. In a three-echelon
multiple commodity supply chain, the aim is to fulfil customer demand at a
minimum cost by optimising the flow of products from factories to distribution
centres (DC) and from DCs to customers. In a situation where there are limited
numbers of DCs and each of them covers bounded area, locating DCs for the
purpose of, maximising coverage of customers’ demand and optimising
allocation of the customers to those centres, are quite important. In this
research, a three-echelon multiple commodity supply chain model with
maximal covering approach that meets the following two objectives through
appropriate selection of DC sites is presented: 1) maximise coverage of
customer demand; 2) minimise the associated transportation cost required for
fulfilment of the customer demand. To address such models in small scales, one
can easily apply LP-metric method to make a combined dimensionless
objective and solve it with lingo software. Considering the fact that the
presented model is an NP-hard problem and cannot be solved in this manner,
we apply customised version of a heuristic algorithm named Greedy and clearly
indicate its robustness.
