Abstract:

The goal of this study is to propose a tentative model for performance evaluation of provincial gas companies in the National Iranian Gas Company (NIGC),based on a combined approach including Balanced Score Card and Fuzzy TOPSIS. Balanced Score Card was used to design the performance evaluation index and Fuzzy  Topsis to determin final scores and ranks of provincial gas companies. In the proposed approach, effective criteria for companies’ performance  evaluation  were firstly determined on  the basis of Balanced Score  method, in four respects: customer, internal processes, growth/Learning, and financial. These criteria were subsequently finalized gathering expert opinions.The effectiveness of such criteria in companies’ performance assessment were determined using questionnaire and expert opinions. Furthermore,due to the variable environment of the issue under consideration, the Fuzzy Topsis was drawn upon fuzzy concepts. eventually, the proposed hybrid approach was applied to assign final scors and ranks of five provincial gas companies, i.e. Ilam, Kermanshah, Lorestan, Markazi, and Hamedan.
