Abstract:	The Hepato-Gastroenterology part of the endoscopy department of the Academic Medical Centre faces big problems. The access times, the time patients have to wait for a consultation, are far too long, but the physicians and nurses felt they already needed to work too hard. The planning was not optimal, as it did not spread the usage of scopes and the recovery room and did not always provide residents to learn. The planning was also a cause of the long access time, as the skipping of shifts and the bad division of capacity under the consultation types are main causes for not meeting the access time standards. This research tries to improve the planning approach. We recommend implementing a planning approach based on an iterative usage of simulation and Mixed Integer Linear Programming (MILP). This approach delivers master schedules, which the department can easily incorporate in the planning. One can use heuristic 1 to solve the MILP, but the solution quality varies for different data sets. We also recommend buying no OGD-suction for room 120 or new x-ray system for room 213. The proposed approach delivers a master schedule, which will bring the access time into the standards. The approach also decreases the number of double bookings, which normally result in overwork. The developed Mixed Integer Linear Programming (MILP) does also take the maximum usage of the recovery room and the OGD-scopes into account. Furthermore, this new planning approach is more robust than the old, manually one. Direct solving the MILP gives better solutions, so is preferable above the proposed heuristic. Implementing a new planning approach does bring many changes. The planning for the physicians will change and they need to adapt to it. Another consequence is that the department needs to do the planning process in a new way, partly also by other people
