FAILURE MODES AND EFFECTS ANALYSIS USING FUZZY TOPSIS IN KNITTING PROCESS

Musteri memnuniyetini saglamak icin hatalari tespit etmek, ortadan kaldirmak veya en aza indirmek onemlidir. Hata turu ve etkileri analizi (HTEA), kalite iyilestirme icin etkin bir arac olarak kabul edilmektedir. Bu calismada; FMEA, orme surecinde bulanik TOPSIS kullanilarak gerceklestirilmistir. Bulanik mantigin gercek dunya problemlerindeki kesin olmayan enformasyonla ve belirsizlikle basa cikma becerisi nedeniyle, bulanik yaklasimi TOPSIS teknigine entegre edilerek kullanilmistir. Bu sekilde, hatalarin uzmanlar tarafindan dilsel degiskenler kullanilarak onceliklendirilmesi, yoneticilerin daha guclu oncelik siralamasina sahip en kritik olanlara odaklanmalarina olanak tanir.Bu calismada elde edilen sonuclara gore, merdane cekim hatasi, yag lekesi, olcu esitsizligi, tuse hatasi, kacik patlak, desen hatasi ve iplik kopmasi kritik hatalar olarak belirlenmistir. Bu hata turleri genellikle orgu makinesinin ayarlarinin dogru yapilmamasindan kaynaklanmaktadir. Bu hatalari gidermek icin; fabrikadaki egitimlerin sayisinin ve kalitesinin arttirilmasi, surekliliginin saglanmasi ve duzenli makine bakimlarinin yapilmasi onemlidir
