A MATHEMATICAL PROGRAMMING APPROACH FOR FACILITIES RELOCATION PROBLEM IN SUPPLY CHAIN

Facilities' location in supply chain is one of the fundamental and strategic decisions of supply chain management. As location models in supply chain take in to account more factors simultaneously, they are commonly more complicated than traditional location models, but their structures are almost resemble to the traditional models. Location in any time is corresponding to that specific time conditions, and a location that is appropriate for one of the facilities, because of the condition's change may not be appropriate for the same facilities after years. In this paper a mathematical model is proposed for facilities relocation problem in supply chain. This model can help for deciding about supply chain location changes, constructing new facilities, and appropriate time for those jobs.
