Evaluating the satisfaction level of citizens in municipality services by using picture fuzzy VIKOR method: 2014-2019 period analysis

Abstract

In this study, it is aimed to rank the satisfaction levels of the municipality services. For this purpose, 20 municipal services included in the Life Satisfaction Survey (LSS) that the Turkish Statistical Institution regularly applies every year are considered as alternatives. In addition, the satisfaction of citizens was evaluated not only for the last year, but also for the period of 2014-2019, and these years were considered as a set of criteria. LSS statistics contains the citizens' responses which involve such opinion as abstain and refusal besides yes or no answers. For analyze the effect of all types of opinions on decision process, the participant responses constituting the dataset were converted into Picture Fuzzy Numbers (PFNs) consisting of 4 parameters (positive, neutral, negative, and refusal). Finally, we apply utilize VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) method by using PFNs arithmetic operators and evaluate the citizens’ satisfaction levels of the municipality services. As a result, it was determined that the municipal services with the highest satisfaction were graveyard (A18) and fire-fighting (A17) activities, while the services with the lowest satisfaction were zoning and city planning (A10) and control of food producing facilities (A20).

Novel Development to the Theory of Dombi Exponential Aggregation Operators in Neutrosophic Cubic Hesitant Fuzzy Sets: Applications to Solid Waste Disposal Site Selection

“…e Dombi Bonferroni mean operators of neutrosophic cubic hesitant fuzzy sets will be established. e Dombi exponential laws and Dombi exponential aggregation operators for Pythagorean fuzzy sets and picture hesitant fuzzy sets will be established [51][52][53][54][56][57][58][59][60].…”

“…Riaz and Farid [50] established picture fuzzy aggregation approach and applied it to the third-party logistic provider selection process. Several researchers [51][52][53][54], proposed useful techniques and successfully applied their models to solve decision-making problems.…”

A Novel IMF SWARA-FDWGA-PESTEL Analysis For Assessment Of Healthcare System

“…Consideration of the problem of decision-making in the presence of a number of influential factors has become an extremely important area. Methods, techniques, approaches that belong to the field of multicriteria decision making (MCDM) (Alosta et al 2021;Yildirim et al 2022;Pamučar and Savin, 2020) become very popular and applicable in all fields of both science and profession (Mahmutagić et al 2021;Karagoz et al 2021;Stanujkić et al 2021;Švadlenka et al 2020;Shekhovtsov et al 2021;Özdağoğlu et al 2021). They have practically become an indispensable tool for efficient management of any system, thanks to their very flexible performance If we add to that the possibility of making decisions in different conditions of uncertainty Mishra et al 2021;Bausys et al 2021;Stanujkić et al 2021) then it is clear why this is one of the most developed areas of operational research in the last 10-15 years.…”
