This is a proposal of the content of a licentiate thesis in Innovation and Design at Mälardalen University, Sweden. The contents of the licentiate thesis are concerning Condition Based Maintenance (CBM) in technical systems. The need to make more effective maintenance actions have been shown in various national and international scientific papers. It has also been shown that the traditional mai...

Maintenance has gained in importance as a support function for ensuring equipment availability, quality products, on-time deliveries, and plant safety. Cost-effectiveness and accuracy are two basic criteria for good maintenance. Reducing maintenance cost can increase enterprise profit, while accurate maintenance action can sustain continuous and reliable operation of equipment. As instrumentati...

This paper deals with the condition based maintenance modeling for availability analysis of repairable mechanical systems using MARKOV analysis. Maintenance actions are selected out of four actions namely no repair, minor maintenance, imperfect maintenance and major maintenance. The various probabilities of selecting the maintenance depend upon the level of degradation. Thus system MARKOV model...

The objective of condition based maintenance (CBM) is typically to determine an optimal maintenance policy to minimize the overall maintenance cost based on condition monitoring information. The existing work reported in the literature only focuses on determining the optimal CBM policy for a single unit. In this paper, we investigate CBM of multi-component systems, where economic dependency exi...

in this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. for these types of systems avoiding failure during the actual operation of the system is extremely important. in this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...
