The roster has to take into account severalrequirements such as minimal allocation of a station, legal regulationsand wishes of the personnel. This planning is very complex and isstill done manually. INTERDIP is an advanced industrial prototypethat supports semi-automatic creation of such rosters. Using constraintbased programming, INTERDIP imitates certain aspects of manualplanning. With INTERDIP a roster can be created interactively withinsome minutes instead of by hand some hours. Additionally, it mostlyproduces better results. INTERDIP was developed in collaborationwith Siemens Nixdorf. It was presented at the Systems98 Computerexhibition in Munich and several companies have inquired to marketour system.1 IntroductionMany real-life problems lead to combinatorial search, computationally a veryintensive task. Unfortunately, no general method exists for solving this kindof problems eciently. The automatic generation of duty rosters for hospitalwards falls under this class of problems.INTERDIP is an acronym for the German \Interaktiver Dienstplaner.yTh
