The art of managing materials; logistics play a
crucial role in efficiency and productivity of companies. 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.
