A fuzzy analytic network process (ANP) model for measurement of the sectoral competititon level (SCL)

摘要

The purpose of this study is to measure the sectoral competition level (SCL) of an organization within the framework of Porter’s five forces analysis by using fuzzy analytic network process (ANP) technique. The framework of the study was based on two main thoughts: First is the necessity to approach to the problem on fuzzy logic basis because of complexity and vagueness, which are inherent in the nature of the competition concept. Second is the necessity to take into consideration the mutual interactions between factors as five forces analysis of Porter suggests so in order to determine SCL. In the scope of the study, firstly the factors and sub-factors which have an impact on the competition level were determined and then inner dependencies between models and factors were examined. The weights of sub-factors were determined on the basis of these examined dependencies and these weights were used for a case study to determine SCL.
