study of the relationship between information systems’ capabilities and firms’ performance based on resource base attitude using fuzzy ahp techniques

according to the resource based attitude, the capabilities of information systems improve firms’ performance and competitive advantages through three ways: 1) inside-outside capabilities, 2) outside-inside capabilities and 3) spanning capabilities. because of the importance of systematic study on the relationship between these capabilities and firms’ performance this paper was aimed at investigating this relationship using fuzzy analytic hierarchy process (fahp). we utilized the fahp because of existing several indices, complexity of decisions and uncertainties that are intrinsically involved in the evaluation of these capabilities. the results imply that among the criteria, return on sales and cost of sold goods are two key criteria that facilitate firms’ success. moreover, inside-outside capabilities regard a good stimulus for improving firms’ performance. then, firms’ internal capabilities are more important in responding to market than outside-inside capabilities.
