Bir Üretim Hattında Toplam Ekipman Etkinliğinin Ölçülmesi Ve Geliştirilmesi Üzerine Bir Uygulama

Toplam verimli bakım çalışmaları yalın üretim felsefesinin önemli bir basamağıdır. Toplam verimli bakım, üretim faaliyetlerinde kullanılan ekipmanların verimliliğini arttırmak ve olası makine hatalarından kaynaklanacak bozuk veya hatalı parçaları önlemek amacıyla yapılan çalışmaların tümü olarak ifade edilebilir. Yalın üretim ve toplam verimli bakım uygulamalarının ölçülmesinde ise Toplam Ekipman Etkinliği kavramı karşımıza çıkmaktadır. Bu kavram işletmelerdeki makine ve ekipmanın ne derece etkin kullanıldığını ölçmemize yardımcı olmaktadır. Bu çalışmada, işletmelerde verimlilik açısından Toplam Verimli Bakım’a değinilmiş, Toplam Ekipman Etkinliği’nin işletmeler açısından önemi açıklanmış ve bir makarna üretim tesisindeki üretim hattının Toplam Ekipman Etkinliği değerleri hesaplanmıştır. Bu hesaplama sonucunda makine duruş sürelerinin yeteri kadar düşük olmadığı tespit edilmiş ve bazı iyileştirmeler yapılmıştır. Son bölümde ise, Toplam Ekipman Etkinliği değerlerinin ideal değerlerle karşılaştırılması yapılmış ve üretim hattı duruş süreleri, iyileştirme öncesi ve sonrası değerlere göre değerlendirilmiştir.

An Application on the Measurement and Improvement of Overall Equipment Efficiency in a Production Line

Total productive maintanance work is an important step of lean production philosophy. Total productive maintanance can be defined as the whole of the works performed to increase the productivity of the equipments that are used in production activities and to prevent the defected parts that result from the probable machine error. We come across the term of Overall Equipment Efficiency for the measurement of the lean production and total productive maintenance implementations. This term helps us measure how efficiently the machine and equipment are used in the workplace (uygun gibi). In this study, Total productive Maintenance was mentioned in terms of productivity in businesses the importance of overall equipment efficiency was expressed for businesses and the values of overall equipment efficiency of the production line in a pasta production plant were calculated. As a result of this calculation, it was determined that the machine stoppage was not low enough and some improvements were made. In the last chapter, the values of Overall Equipment Efficiency were compared to ideal values and production line stoppages were evaluated in terms of values before and after the improvement.
