Application of the COPRAS Method in the Decision-Making Process

Öz

Multi-criteria decision-making methods analyze the decision-making process in an environment with many interrelated criteria and alternatives. The main purpose is to choose the best alternative or to determine the performance ranking of a given number of alternatives. Decision making is when a decision maker chooses from among often conflicting criteria on a particular issue. These methods guide the decision maker in finding the best solution. In doing so, they compare ideal solutions with non-ideal solutions. The aim of the study is to apply the COPRAS method in the decision making process. A case study has been conducted for this. Western Europe: Current Quality of Life by City Index was used to demonstrate the application. According to the results of the COPRAS method for evaluating the current quality of life by Western European city, the top five cities with the best quality of life are respectively The Hague (Den Haag), Eindhoven, Vienna, Zurich, and Düsseldorf. Sensitivity analysis shows that the results found are reliable. As a result, the COPRAS method provides flexibility to the decision maker in all areas.

Karar Verme Sürecinde COPRAS Yöntemi Uygulaması

Öz

Çok kriterli karar verme yöntemleri birbirleriyle ilişkili çok sayıda kriter ve alternatifin olduğu bir ortamda karar verme sürecini analiz eder. Temel amaç en iyi alternatifi seçmek veya verilen çok sayıda alternatifin performans sıralanmasını belirlemektir. Karar verme bir karar vericinin belirli bir konuda genellikle çelişen kriterler arasından seçim yapmasıdır. Bu yöntemler karar vericiye en iyi çözümü bulma konusunda yol gösterir. Bunu yaparken ideal çözümler ile ideal olmayan çözümleri karşılaştırırlar. Çalışmanın amacı karar verme sürecinde COPRAS yöntemi uygulamasıdır. Bunun için bir vaka çalışması yapılmıştır. Uygulamanın gösterimi için Batı Avrupa: Şehre Göre Mevcut Yaşam Kalitesi İndeksi kullanılmıştır. Batı Avrupa şehre göre mevcut yaşam kalitesi değerlendirilmesine yönelik COPRAS yöntemi sonuçlarına göre, en iyi yaşam kalitesine sahip ilk beş şehir sırasıyla Lahey (Den Haag), Eindhoven, Viyana, Zürih, ve Düsseldorf şehirleridir. Duyarlılık analizleri bulunan sonuçların güvenilir olduğunu göstermektedir. Sonuç, COPRAS yöntemi, karar vericiye tüm alanlarda kullanılabilir bir esneklik sağlamaktadır.
