  abstract  = {F{\"u}r die Erstellung von Maschinenbelegungsplanen wurden im Operations Research aufwendige Optimierungsverfahren konzipiert und entsprechende Programme entwickelt. Maschinenbelegungsprobleme sind klassische Vertreter der Klasse der np-vollst{\"a}ndigen Probleme, also sichere Kandidaten f{\"u}r kombinatorische Explosion der L{\"o}sungsalternativen. Deshalb ist der Einsatz konventioneller Planungssysteme wegen der hohen Rechneranforderungen der g{\"a}ngigen Verfahren an die Hardware oft nicht praktikabel.},

The 3rd Workshop on Requirements Prioritization for customer oriented Software Development (RePriCo'12) focused on requirements prioritization and adjacent themes in the context of customer oriented development of bespoke and standard software. Five submissions have been accepted for the proceedings and for presentation. The report summarizes and points out key findings.},
