Ways to improve the performance of a plant

Nowadays many companies are interested to improve their production system. It has become important in globalize and competitive market for the survival. The companies are looking to their production systems in the different direction to get the competitive advantages. But the most important is to find out the problem of the production system to make improvements.In this thesis, a part of the production system of a company is studied to find the problems of the production system to make the improvements and to recommend some points to the company for the achievements of its goals. For this purpose, the overall equipment effectiveness calculations have been used to see the current situation of the production system of the company. These calculations of the O.E.E. of the different production work stations make the clear picture of the problems. It calculates the availability of the production system which shows that maintenance system’s effectiveness…
