Abstract
Maintenance is the combination of all technical, administrative and managerial actions during
the life cycle of an item intended to retain it in, or restore it to a state in which it can perform
the required function. Nowadays, many of the industries in our country faced with the
problem of maintenance which results in poor productivity. Therefore, improved maintenance
system is an important task to enhance the productivity. In this study, the maintenance
problems of Dashen Brewery Share Company and development of improved maintenance
system were studied. The study were assessed the existing maintenance system of the
company, differentiate the factors affecting productivity, investigate and analyze the
maintenance problems.
Two sets of data which are required for the study are collected from the company, data has
been obtained from a structured questionnaire response which is distributed for a sample size
of 60 respondents drawn from Dashen Brewery Share Company maintenance department
workers and machines downtime data were obtained from the annual recorded report of the
company.
The collected data have been analyzed by analytical tools, which are Microsoft Excel, Pareto
and SPSS analysis and proposed solution is given to improve the productivity of the
company. These analyses are used to identify the key area which faces high downtime in the
case company. In filler machine the filling valve is the critical component which causes the
loss of production. Since the designed production capacity of the industry is 48,000 bottles/
hr and its actual production capacity is 31,000 bottles/ hr which means the industry produces
64.5% of its designed capacity and the company losses 82,442,775.21 birr/hr due to machine
downtime and maintenance. This has resulted from the poor reliability of their production
systems as a result of poor or insufficient maintenance. But if the industry implements the
proposed solution, the company almost meets the planned capacity, i.e. 42,000 bottles/hr,
which is the industry produces 87.5% of its designed capacity and the loss of money due to
maintenance and downtime costs the company increases the profit by 17.41% and can
improve the productivity. The results show the importance of the development of
maintenance strategies through the implementation of RCM in this company and depending
on the problems the model is developed. The purpose of it would be to overcome the
problems that could secure the reliability of the production systems.
