Maintenance costs, savings and benefits in manufacturing

• More efficient maintenance yields in increased production, lower costs and higher product quality promoting company's business. Data will be used in a Decision Support System (DSS) to achieve cost-effective decisions, improve maintenance strategy and increase company's profit. In this paper, an Information Technology (IT) System, i.e. GMDSS, supporting the concept of total quality maintenance (TQMain) is developed. This system consists of a Database Management System (DBMS), DSS and the interaction between these components and between the system and it's environment. The system is verified in real data from a Swedish paper mill. The major results are maintenance direct costs, savings and benefits are considered instead of direct and indirect maintenance costs. Economic losses are considered as potential savings when a more efficient maintenance is used. Further, vibration-based maintenance (VBM) saved annually about 4 MSEK. It is about nine times the investments done in maintenance. which were between 1-2.2% of the total potential savings. The mean conclusion of this study is using this methodology for assessing maintenance economic role, it would be classified as a profit-centre.
