It is very significant to determine most influential logistic factors since logistic costs account for 30% of total company costs. The factors affecting success of logistic enterprises such as cost, speed, reliability, customer satisfaction, distribution channel, company image, environmental friendliness and technological innovations are investigated and ranked in this study. Three different approaches based on Pythagorean Fuzzy sets, triangular fuzzy numbers and Analytic Hierarchy Process is offered for ranking these factors. Although it has been introduced to literature recently, the pythagorean fuzzy sets are widely employed in calculating uncertainty. The three most influential logistic factors are revealed as cost, speed and reliability, respectively by employing AHP, Fuzzy AHP and Pythagorean Fuzzy AHP, however factor weights are different. We think that the differences with in the AHP, F-AHP and PF-AHP results may stem from expressing evaluations in exact values, linguistic terms or in some cases it may be related to fulfilling the condition of membership and non-membership. Furthermore, top 10 logistic firms in Turkey are scored and ranked to these factors. Logistics, Pythagorean fuzzy sets, AHP, Fuzzy AHP, MCDM.
