ABSTRACT
While selecting a global facility location, the decision makers normally have to face two types ofscenarios: exploring and prioritizing the factors affecting the location decision and selecting an appropriate optimization methodology,- compatible to the said problem. This paper addresses a real world case study of the problem of selecting a country best suitable for a new cement plant installation among the list offour alternatives. The irreversible nature of the crucial decision requires analysis of wide range offactors with different optimization techniques. Therefore such factors were explored and prioritized from available literature and by recommendations ofpanel ofexperts followed by mathematical modelling of the said problem in four standard methodologiesincluding the one presented in another paper earlier. Thesolutionswere obtained by coding routines in theconcerned programs.Stability analysis with respect to change ofpriorities and change of cost and capacity constraints has provided an in depth scenario evaluation which has added value to the degree of reliability and confidence regarding acceptability of results. The paper is a unique contribution for strategic managers of the cement sector being an aid tomake confident global decisions.
