Two main reasons for this shortage are an increased demand for healthcare and a shortage on the healthcare labour market.

Integration of Condition Based Maintenance in the Preventive Maintenance Planning of Rolling Stock

Planning rolling stock maintenance based on prognostic data (Condition Based Maintenance, CBM) is a trend since the ideal timing for maintenance before failure can be planned. With the use of prognostics, a failure can be predicted so Corrective Maintenance (CM) can be avoided. Traditional rolling stock decision-making for Preventive Maintenance...

Annualized hours: Comparing an exact optimization model with its approximation

In this thesis, we propose two mixed integer linear program formulations for an optimization problem that incorporates annualized hours: an exact one and an approximation. The objective of our model consists of three weighted parts: a part which minimizes the difference between working hours and contract hours for each employee per week, a part...
