We consider the multi-mode resource-constrained project scheduling problem. The focus is on an algorithm which is supposed to find a makespan optimal solution. This algorithm has been presented in a recent paper by Speranza and Vercellis. The correctness of the algorithm is examined. Moreover,...

We consider an extension of the classical resource-constrained project scheduling problem (RCPSP), which covers discrete resource-resource and time-resource tradeoffs. As a result a project scheduler is permitted to identify several alternatives or modes of accomplishment for each activity of...

In der vorliegenden Untersuchung wird die operative Entscheidung über Eigenfertigung und Fremdbezug betrachtet. Exemplarisch wird dargelegt, dass klassische Entscheidungshilfen unwirtschaftliche Ergebnisse hervorbringen. Die qualitative und quantitative Fehlspezifikation der Fremdbezugsprodukte...

Sales force management decisions belong to the major issues considered in marketing research. Among others, the alignment of sales territories has been one of the main field of work for years. Recent results have reported a strong impact of the alignment of sales territories on profit, and,...
