Licentiate Thesis Proposal Condition Based Maintenance in Technical Systems
نویسنده
چکیده
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 maintenance techniques, corrective and preventive, are very costly (mostly due to lost productivity and high cost for spare parts). With CBM one utilizes predictive maintenance, i.e. perform maintenance based upon need. One assesses the condition of the assets and makes judgements whether or not maintenance should be performed. This means that the maintenance intervals will be decided dynamically. Vibrations-, temperature-, oil-, acoustic analysis etc. will reveal the condition. A lot of research has been performed over the past decades, the electronic industry has developed reliable sensors and signal processors and researchers all over the world has developed algorithms and monitoring equipment. The research is mostly developed towards specific applications and hard to reproduce in large scale. There are also just a few areas in the industry where CBM (or possibly even just condition monitoring) have gained acceptance. This thesis will explain how a more general CBM system can be built as well as how CBM could be implemented at a larger corporation.

Licentiate Thesis Proposal Clustering and Case-Based Reasoning for User Stereotypes
This document presents a proposal for the contents of a licentiate thesis in computer science at Mälardalen University, Sweden. The main subject of the thesis is the usage and creation of user stereotypes, aided by the use of clustering techniques to find similar groups of users. To reason about and maintain the user stereotypes, we primarily use Case-Based Reasoning (CBR). The techniques prese...

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
