Abstract
By identifying the bottlenecks in the business process, improvements are made on the relevant process.For this, first of all, the maturity of the business process should be determined.In the literature, the process maturity model is used to measure the maturity level of processes.The model is questionnaire-based.It includes an evaluation in 0-1 logic.However, the current structure is not sensitive enough to reflect the decisions of group decision-makers.Therefore, a fuzzy set and Analytic Hierarchy Process (AHP) based approach has been proposed to measure the maturity level of processes.The effectiveness of the method is demonstrated by applying the proposed approach to the vehicle tracking process (VTP) of an organization.
