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.

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.
