KALİTE İYİLEŞTİRME SÜRECİNİN YEDİTEMEL ARACI VE MOTOR-TRAKTÖR İMALATI YAPAN BİR İŞLETMEDE UYGULANMASI

İstatistiksel Proses Kontrol İPK bir ürünün en ekonomik ve yararlıbiçimde üretilmesini sağlamak amacıile istatistiksel prensip ve tekniklerin, üretimin tüm aşamasında kullanılmasıdır. Bu anlamda en çok bilinen yöntemler “Ishikawa’nın Yedi Temel Aracı” olarak da bilinen; sınıflandırma, çetele, histogram, pareto analizi, neden-sonuç diyagramları, serpilme ve kontrol grafikleridir. Bu çalışmada bu yedi temel araç ele alınarak motor ve traktör imalatıyapan bir işletmede bu tekniklerin kalite iyileştirme çalışmalarındaki kullanımlarıincelenmiştir. Yapılan literatür incelenmesinden sonra, işletmede istatistiksel proses kontrol araçlarının kullanılmasıile kalite iyileştirme ve geliştirme süreci incelenerek, bu teknikler yardımıile işletmenin kalite gelişimini olumsuz yönde etkileyen faktörler belirlenmişve bu faktörlerin ortadan kaldırılmasıiçin sebep-sonuç diyagramlarıgeliştirilerek çeşitli önerilerde bulunulmuştur. Ayrıca kontrol diyagramlarıyardımıile proseslerin kontrol altında olup olmadıklarıincelenmişve kontrol dışıdurumlar için sebep-sonuç diyagramlarıgeliştirilmiştir.

Statistical Process Control SPC is the usage of statistical principles and techniques at all stages of the production, to provide the production of a product in the most economical and effective way. The most popular technique for this purpose is Ishikawa’s methods. Seven basic Ishikawa’s tools of SPC are; satisfaction, check sheet, histogram, Pareto Analysis, cause and effect diagram, scatter diagram and control chart. In this study, these techniques are explained shortly and effect of these techniques for quality improving process in engine and tractor factory. Factors which are impact quality improving process negatively are determined and cause and effect diagrams were suggested to eliminate them. And control charts were occurred to cleared process status
