ÖzAcil servislerde iş sağlığı ve güvenliği ile ilgili risklerin belirlenmesi ve bu risklere karşı gerekli önlemlerin alınması; sağlık çalışanlarının iş yüklerinin azaltılması ve sağlık hizmetlerinin kalitesinin arttırılması için son derece önemlidir. Bu nedenle uygun risk değerlendirme yöntemleri kullanılarak risk kriterleri (faktörleri) ve bu kriterleri azaltmak için alınacak risk önlemleri belirlenmelidir. Bu çalışmada; acil servislerde risk değerlendirilmesi için Hata Türleri ve Etkileri Analizi (HTEA) tabanlı Kemeny Median Indicator Ranks Accordance-Modified (KEMIRA-M) yöntemi önerilmiştir. İlk aşamada; HTEA yöntemi kullanılarak uzman görüşlerine göre risk kriterlerinin öncelikleri bulunmuştur. İkinci aşamada ise; KEMIRA-M yöntemi ile elde edilen medyan matrisine göre kriter öncelikleri belirlenmiş ve bu önceliklere göre risk kriterlerini azaltıcı önlemler açıklanmıştır. KEMIRA-M yöntemi hem HTEA yöntemi ile geliştirilmiş hem de ana ve alt kriterlerden oluşan hiyerarşik bir yapıdaki kriter grubuna uygulanmıştır. Önerilen yöntem ile acil servislerde yapılan risk değerlendirmesi sonucunda güvensiz nöbet-vardiya ortamı, tıbbi cihazlar ve ergonomi ile ilgili riskler en önemli risk kriterleri olarak belirlenmiştir. Bu risklerin azaltılması için çalışma koşullarının ergonomik açıdan düzenlenmesi, kişisel koruyucu donanımların kullanımı ve işçilere eğitim/seminer verilmesi önerilmiştir.

“…These researchers stated that FMEA in the IF environment is a useful tool for identifying and evaluating failure modes in various fields to improve security and reliability (Lv et al , 2019; Şenel, 2018; Tooranloo et al , 2018). Among the multi-criteria decision models, the unique features of the Elimination Et Choix Traduisant la REalité (ELECTRE) method such as the use of superiority and indifference thresholds (Buchanan et al , 1999; Hu, 2009; Bojković et al , 2010) as well as indicators, such as support for data types with ranking, numerical and hybrid scales, support for pairwise comparisons, support for quantitative and qualitative criteria, ability to work with a multitude of alternatives and criteria, its compensatory nature and high separation power of criteria (Figueira et al , 2013; Guitouni and Martel, 1998; Hatami-Marbini and Tavana, 2011), have led to the use of ELECTRE technique in FMEA in several studies (Liu et al , 2015; Anes et al , 2018; Silvia et al , 2018; Liu, 2019; Şimşir et al , 2018; Certa et al , 2017).

Purpose In this way, the aim of this study is to expand and evelop the application of this technique in FMEA to rank failure modes of ESQ of academic libraries in an intuitionistic fuzzy environment. Assessment of electronic service quality (ESQ) of libraries is significantly important according to their major roles. It should be noted that the ESQ has a significant impact on customer satisfaction, which improves organizational performance. Accordingly, low ESQ means waste of organizational resources and poor user satisfaction. So, there is a dire need to reflect reasons inducing failure modes in academic library ESQ. Thus, investigation of failure modes affecting academic library ESQ is highly important. One solution in this area is utilization of the intuitionistic fuzzy (IF) failure mode and effects analysis (FMEA) as one of the widely used methods for prediction and identification of failure modes. Design/methodology/approach The present study in terms of objective is applied and in terms of the type of method is descriptive-analytical. The research sample included four experts of Yazd academic Libraries (Iran). To collect data, three types of questionnaires were distributed among experts. The purpose of the first questionnaire was to identify and reach an agreement on e-library failure modes. Type II questionnaire was used to determine the importance of identified risk factors and Type III questionnaire was used to prioritize the factors. Findings Results indicate that the difficulty of using websites, lack of provided information feedback to users and lack of links on the website to users' are the main priorities for improving ESQ in the studied academic libraries. Originality/value In this approach, the Intuitionistic fuzzy Elimination Et Choix Traduisant la REalité and technique for order of preference by similarity to ideal solution method were used to rank failure modes in academic library ESQ within the FMEA framework.]

It is necessary for the companies to use a structured method to manage a powerful reliability, and to made risk analysis is essential. Risk analysis refers to the studies required to determine the existing or potential hazards for companies, to analyze and rate the risks arising from these hazards and to prevent them from occurring. There are several methods of risk analysis. Failure Mode and Effect Analysis (FMEA) is a method that is to ascertain the failures and dangers in the system without causing any accidents and to make them better by starting from the top priority of them. This method is used to define how the system can be developed to increase reliability and make free from failures. In this study, it is aimed to determine the mistakes that may occur in the processes of a company that produces transformers and to take precautions and increase the reliability of the company. The power transformer product group of the company has been focused on, and fuzzy logic based failure mode and effect analysis (Fuzzy FMEA) has been used to prioritize risks. High risk priority values and failures that need to be improved have been identified by design and process FMEA studies in the classical FMEA. Considering the deficiencies such as use of linguistic expressions in the calculation of risk priority value and the depens on the person of the evaluation, it was concluded that using Fuzzy Logic based FMEA method would be beneficial. When the risk priorities of the failures obtained as a result of the Fuzzy FMEA studies are evaluated, it is seen that the method used is closer to the truth, and a FMEA monitoring system has been developed to ensure the effectiveness and continuity of the work carried out in the company.
