In strategic level countries are assessed according to international economic indices available in Global Competitiveness Report (GCR (and in operational level regarding the obtained values and factors like establishment costs, transportation costs, capacity and demand a multi objective optimization model is developed.The problem includes three objective functions: finding the least number of facilities, locating them in the best possible locations and minimizing transportation costs. A demonstration of the application of the methodology is presented by investigating the location problem of an international pharmaceutical company in Europe. https://imj.ut.ac.ir/article_57424_9037c8d6516fc5f9a5e1e7fd30459de2.pdf
