Abstract:This master thesis gives an insight in designing a model used to get an overview needed to make a well-founded repair / replace decision. That is done by answering the questions of how NTS Norma can gain overview and make a well-founded repair / replace decision regarding milling machines and which input is needed for this decision in the future. This is done by using the method asset management as a guide. Concluded is that the knowledge within the organization and people is high at NTS Norma, but the other topics need more clarification to design a well-founded repair / replace decision. This clarification is given by dividing the process into three categories: Vision, technical life model and economical life model. With these three categories, a model is made that can be used to give insight and foundation in the repair/replace decision. This model is different from other models. Normally, models are using calculations to calculate the optimal repair/replace decision. This new designed model uses information from data and people, to gain overview of the situation. This information can be used by the decision maker to make the repair/replace decision.
