Bu çalışmada iş güvenliği risklerinin değerlendirilmesi için yeni bir hata türü ve etkileri analizi (HTEA) modeli önerilmiştir. Klasik HTEA’ya göre risk öncelik sayıları (RÖS), olabilirlik, şiddet ve fark edilebilirlik puanlarının çarpılmasıyla hesaplanır. Bununla birlikte, klasik HTEA tarafından oluşturulan RÖS değerleri literatürde ağır eleştirilere konu olmuştur. Bu çalışma klasik HTEA’nın dezavantajlarını aşmak için yeni bir Çok Kriterli Karar Verme (ÇKKV) modeli önermektedir. Önerilen risk değerlendirme modeli, tam tutarlılık yöntemini (FUCOM) ve çizge teorisi-matris yaklaşımını (ÇTMY) bulanık ortamda birleştirmektedir. Bulanık FUCOM yöntemi kullanılarak hata türlerinin risk puanları ve risk faktörlerinin ağırlıkları elde edilmiştir. Öte yandan, her hata modunun RÖS değeri bulanık ÇTMY kullanılarak hesaplanmıştır. Bulanık ÇTMY, risk faktörleri arasındaki tüm olası etkileşimleri göz önünde bulundurmakta ve böylece daha doğru sıralamalar üretmektedir. Karar vericilerin bulanık değerlendirmeleri en küçük kareler mesafe yöntemi kullanılarak toplanmıştır. Önerilen model, gerçek hayattaki bir vaka çalışmasında uygulanmış ve hata modları sıralanmıştır.
