    Risk assessment in cheese production process using failure mode and effects analysis and intuitionistic fuzzy topsis

    Ünlükal, Ceren; Şenel, Mine; Şenel, Bilgin; Avarbek, Kenan

    The aim of this study is to evaluate the cheese production process, which plays a significant role in the milk and dairy industry, in terms of physical, chemical, and microbiological risks using the integrated Failure Mode and Effects Analysis (FMEA) and Intuitionistic Fuzzy TOPSIS (IF-TOPSIS) methods. Although the classical FMEA method is a widely used analytical technique that helps identify and reduce potential risks in processes, it has some drawbacks: such as the possibility that different failure modes may have the same risk priority values (RPN) and risk factor weights. To address this shortcoming, the intuitionistic fuzzy set theory was used to determine the RPN values. This study aimed to identify failures that may occur at critical steps in the production chain, their possible causes, their impact on product quality, and the priority of preventive actions. The study demonstrates that the intuitionistic fuzzy multi-criteria decision-making (MCDM) approach is an effective tool for food safety and quality management in the dairy products industry.

    Infection transmission risk analysis in Covid-19 intensive care nurses

    Şahin, Melek; Şenel, Bilgin; Şenel, Mine; Ünlükal, Ceren

    The coronavirus pandemic, which affects the whole world, continues to spread rapidly. The pandemic has reached a serious extent and the risks are getting deeper. The sector most affected by the pandemic has been the health sector and health personnel have become an indispensable element of this process. The people at highest risk of being infected are nurses who are in contact with or are responsible for the care of COVID-19 patients. This study was conducted to investigate the transmission risk of COVID-19 infection among nurses who care for patients in intensive care units.In this study, to prevent the transmission of infection from patient to nurse, possible failures in the process were determined by experts selected from nurses, and risk analyses were performed using Failure Mode and Effects Analysis and Entrophy-based Grey Relational Analysis methods. In this study, the three most probable and high-priority failure types were determined in the failures made in the procedures for the transmission of the infection from the patient to the nurse.There is a need to increase the quantity and quality of intensive care unit care personnel to manage new waves of COVID-19 or possible pandemic situations effectively.

    Havacılık sektöründe sezgisel bulanık topsıs yöntemiyle risk analizi uygulaması

    Ünlükal, Ceren; Yücel, Mustafa

    Hata Türü ve Etkileri Analizi (HTEA), birçok sektörde potansiyel hataları tanımlamak, değerlendirmek ve önlemekiçin sıklıkla kullanılan risk analizi tekniklerinden biridir. HTEA, süreçler ve ürünlerdeki potansiyel risklerinbelirlenmesine ve azaltılmasına yardımcı olması ve yaygın olarak kullanılması gibi güçlü yönleri olan analitik birteknik olmasına rağmen bazı noktalarda eleştirilmiştir. Risk değerlendirmesini yapan uzmanlar ve karar vericilertarafından, risk faktörlerine 1 ile 10 arasında matematiksel bir sayı atamak kolay değildir. Bu noktada sezgisel bulanıkmantık yaklaşımının sunduğu dilsel değişkenlerin kullanılması karar vericilere kolaylık sağlamakta ve riskdeğerlendirmelerinin doğruluğunu artırmaktadır. Bu çalışma, havacılık sektöründe faaliyet gösteren bir işletmeninüretim süreci boyunca ortaya çıkabilecek risklerini HTEA ile değerlendirmeyi amaçlamaktadır. Risk faktörlerinin gözardı edilmesi ve risk önceliklerinin doğru belirlenememesi ihtimali göz önünde bulundurularak, çalışmaya sezgiselbulanık mantık yaklaşımı entegre edilmiştir. Bu amaçla risk faktörleri uzmanlar tarafından ağırlıklandırılmıştır.Problem çözümünde Sezgisel Bulanık TOPSIS yöntemi kullanılarak, dilsel değişkenlerin desteğiyle hatalar uzmanlartarafından önceliklendirilmiştir.

    Risk Assessment with Failure Mode and Effects Analysis and Grey Relational Analysis Method in Plastic Injection Process

    This study aims to evaluate the risks that may arise during the production process in a plastic injection manufacturing enterprise with traditional Failure Mode and Effect Analysis (FMEA) and Grey Relational Analysis (GRA). Although it is a widely used analytical technique that helps to identify and reduce the risks of failure in a process, the Failure Mode and Effects Analysis (FMEA) has some drawbacks that the different risks can have the same risk priority values and the weight of risk factors is not take into consideration. This situation has been tried to be eliminated by integrating the FMEA with the GRA. As a result, it is seen that the order of risk priority values of the identified failure changes according to both methods.
