Constraint Programming for Complex Elastic Scheduling

By 

Abstract

Abstract. Elastic scheduling with alternative resources and precedence constraints is described in this paper. Each activity has defined a time window, in which the whole activity must be processed. The goal is to find a schedule minimizing costs on resources. First a special case of the problem is introduced, which deals only with one resource in the schedule. After that a model with more resources is introduced, where each activity has assigned exactly one resource. For this problem no polynomial algorithm is known. Finally a constraint satisfaction optimization model for alternative resources is described. This model uses constraint programming techniques such as edge finding and alternative resources modeling
