摘要：This paper presents a fuzzy mathematical model for the analysis of organizational structure of administrative bodies. The organizational structure of administrative bodies of logistic support of the Petroleum Industry of Serbia has been analyzed in order to analyze the situation and optimize the existing organizational structure. Analysis of the state of organization is aimed at creating a picture of the current mode of organization and, on the basis of that, removing identified deficiencies. This model has been applied for the analysis of process and business functions, and tasks of the administrative bodies of the organizational structure taking into account the fact that administrative bodies should be designed and sized so that they can meet the basic goals and tasks of their existence. Each task set before the administrative bodies should be completed in a quality and reliable way in all environmental conditions. Since most of the data collected during the study of organizational structure are characterized by a high degree of uncertainty, subjectivity and ambiguity, fuzzy logic was used to show the described uncertainties and ambiguities. Fuzzy linguistic descriptors were used to describe the criteria used for assessing the organizational structure. In this way, fuzzy logic has enabled the exploitation of tolerance that exists in imprecision, ambiguity and partial truth of the research results obtained.
