Abstract

In the Industry 4.0 era, manufacturing enterprises need various digital optimization tools to adapt to digital transformation. This study aims to identify the subjective weights of the challenges faced by manufacturing enterprises when implementing Discrete Event Simulation (DES), one of the prominent optimization tools of the Industry 4.0 era. The challenges examined in this empirical research are derived from the existing literature. In this study, three experts responsible for DES implementation and production in their organizations were consulted. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) was used to reflect the subjective weights of the decision criteria and the cause-effect relationships between them. The DEMATEL method is a method used in the Multi-Criteria Decision Making (MCDM) literature to determine the subjective weights of decision criteria. As a result of the study, the importance ranking of the challenges faced by manufacturing enterprises in DES implementation was obtained and the causal relationship between these challenges was determined. Identifying the causal relationship between these challenges can provide decision makers with a competitive advantage in overcoming these challenges. Adoption of the findings of the study will facilitate the adoption of DES, resulting in reduced costs, increased customer satisfaction and competitive advantage for industry professionals.

İMALAT İŞLETMELERİNDE AYRIK OLAY SİMÜLASYONU (DES) UYGULAMA ZORLUKLARININ ÖZNEL AĞIRLIKLARININ BELİRLENMESİ

Abstract

Endüstri 4.0 döneminde, üretim işletmeleri dijital dönüşüme uyum sağlamak için çeşitli dijital optimizasyon araçlarına ihtiyaç duymaktadırlar. Bu çalışma, Endüstri 4.0 döneminin öne çıkan optimizasyon araçlarından biri olan Ayrık Olay Simülasyonunu (DES) uygularken üretim işletmelerinin karşılaştığı zorlukların öznel ağırlıklarını belirlemeyi amaçlamaktadır. Bu ampirik araştırmada incelenen zorluklar mevcut literatürden türetilmiştir. Bu çalışmada, işletmelerinde DES uygulaması ve üretiminden sorumlu üç uzmanın görüşlerine başvurulmuştur. Karar kriterlerinin öznel ağırlıklarını ve bunlar arasındaki neden-sonuç ilişkilerini yansıtmak için Karar Verme Deneme ve Değerlendirme Laboratuvarı (DEMATEL) kullanılmıştır. DEMATEL yöntemi, Çok Kriterli Karar Verme (ÇKKV) literatüründe karar kriterlerinin sübjektif ağırlıklarını belirlemek için kullanılan bir yöntemdir Çalışma sonucunda, imalat işletmelerinin DES uygulamasında karşılaştıkları zorlukların önem sıralaması elde edilmiş ve bu zorluklar arasındaki nedensellik ilişkisi belirlenmiştir. Bu zorluklar arasındaki nedensel ilişkinin belirlenmesi, karar vericilere bu zorlukların üstesinden gelmede rekabet avantajı sağlayabilir. Çalışmanın bulgularının benimsenmesi, DES'in benimsenmesini kolaylaştırarak endüstri profesyonelleri için maliyetlerin düşmesi, müşteri memnuniyetinin artması ve rekabet avantajı ile sonuçlanacaktır.
