Main conclusions. The objective of this research was to compare two different interface agreements, the Min- max interface agreement and the Lead-time interface agreement. For both interface agree- ments, models were developed and simulated in order to answer the research questions. The generate results input data of the repair group Electric at the repair shop of NedTrain is used. The main conclusions of the research are itemized below. Research question 1: The performance of the Min-max interface agreement can be improved by changing the parameters of the turn-around stock and the minimum levels. The performance can be improved for all KPIs; EBO, fill rate, minrate and investment costs. There is a parameter setting obtained, which results in an investment costs decrease from €9,119,108.38 to €3,436,193.45, an increase in fill rate from 0.84 to 0.92, an increase in minrate (percentage of the time the repair shop is able to adhere to the interface agreement) from 0.82 to 0.90 and a decrease in EBO from 13 to 2.5. Depending on the preferences, other parameters settings can be obtained using the optimization model developed. The optimization model works well in case of the Min-max interface agreement.
