Multicriteria modeling for selection of preventive maintenance intervals, based on the multiattribute utility theory

The problem of interval selection for preventive maintenance has been analysed through a multicriteria decision model. This decision model supports decision makers in choosing the best combination of consequences cost and reliability, analysing a context of service production systems. The decision model is based on the multiattribute utility theory. The paper presents the main theoretical and practical aspects related to model building. A numerical application is presented in order to illustrate the use of the decision model.
