Görev Temelli Yeni Bir Stokastik Çok Kriterli Karar Verme Yaklaşımı Önerisi

Abstract

In real life decision problems, the result is generally obtained by using the opinions of a limited number of experts who have sufficient knowledge and experience on the subject of the decision. In the study, a new Multi Criteria Decision Making (MCDM) approach was proposed, which enables new views to be obtained by increasing the number of experts in decision-making processes and modeling uncertainty in expert evaluations in a real-life manner. In this context, two different methods, which are based on the The Multi-Objective Optimization by Ratio Analysis (MOORA) Method, are developed using continuous uniform distribution. These approaches are MOORA Ratio and MOORA Reference Point approaches. Continuous uniform distribution was preferred because each value within a certain range had an equal chance of occurrence. This means that each expert opinion is given an equal chance. Accordingly, by using a limited number of experts' opinions, random numbers are generated with continuous uniform distribution; the results of the evaluation of criteria and alternatives can be increased. Each different assessment represents an expert. Random numbers were generated within this range, taking into account the highest and lowest assessments of current experts. The reason for this is to obtain a preliminary assessment of the decision. However, the proposed approach is a task-based approach and decision-makers make use of relevant alternatives before evaluating them. During this use, decision makers are given different practical tasks. The efficiency of performing tasks enables decision-makers to understand the needs of real users and can be evaluated from a different perspective. The task-based MCDM approach is also important in terms of universal design principles and user satisfaction criteria considered in the evaluation of shopping centers in the study. Two different MOORA approaches have been applied in order to evaluate the shopping centers considering universal design principles and user satisfaction criteria and the alternative rankings obtained have been discussed. In addition, these two different approaches were developed to calculate the importance weights of the criteria. The study involves originality in terms of the proposed new approach and the criteria considered in the evaluation of shopping centers.
