Determination of optimal maintenance strategy and period for an industrial production line

The performance and competitiveness of manufacturing companies depends on the production system and the sustainability, productivity, reliability and protection of the functions of the machinery and equipment associated with this system. Their sustainable safe production performance is ensured by maintenance activities, appropriate maintenance methods and maintenance strategies. Maintenance methods are generally evaluated in two separate parts, planned and unplanned. In periodic maintenance, which is a branch of planned maintenance, and enterprises try to perform their periodic maintenance in the most appropriate time due to their important advantages such as low maintenance cost and positive effects on the availability of equipment. One of the methods that can be applied to determine the most suitable periodic maintenance conditions is the data analysis method. With the data analysis method, it can be determined how often the machines can fail during their working life and how often periodic maintenance should be performed with an approach based on the number of failures in this context. In this study, the importance of maintenance, factors affecting maintenance costs in companies and the type of maintenance management that could be applied to reduce these costs were explained. In order to determine the most suitable period of maintenance in the production line of a company operating in the glass sector, data analysis was performed with the help of mathematical model. In the data analysis model, two criteria mathematical models were determined; maintenance cost and availability. When the results obtained from mathematical model are compared with the maintenance method applied by the company, it is seen that the costs decreased by %53.
