The facility location decisions are inherently strategic and long-term in nature and are also critical to the efficient and effective operation of a competitive supply chain. The transportation, inventory and information sharing decisions can be changed in response to changes in different potential parameters of the competitive supply chain, whereas the facility location decisions are often fixed and cannot be changed, even in the medium-term. Therefore, the successful execution of the decision, i.e. selection of facilities location in competitive supply chain, would give a cutting edge to the organisation. The present work describes a decision support system i.e. performance value analysis (PVA) for a selection of facilities location in a competitive supply chain.
