The lack of resources and the communitie's demands for various goods and services require effective prioritization of investment in different sectors of the economy. Prioritization could optimize resources allocation in addition to improve the social welfare level. This paper provides a framework for prioritizing investment in the services sector according to the aims and policies of A.T. organization. To do this, following determination of factors affecting investment priorities, this paper uses Fuzzy TOPSIS method as a model for setting priorities, since traditional methods in setting priority are insufficient in confronting with vague situations and linguistic evaluations. This method is based on combination of experts and decision-makers’ views in the form of qualitative performance evaluation indicators, which are expressed as triangular fuzzy numbers. The findings indicate that investment in financial and insurance services takes top priority over other services.
