Resource allocation algorithms for robust project scheduling

The article presents the problem of robust allocation of resources in a Resource - Constrained Project Scheduling Problem. It discusses the importance of robust scheduling for execution of actual projects. The issue of resource allocation is analysed for a model project, with indication of allocation principles, which may influence the increase in robustness of the obtained resource allocation network. The author also proposes measures for resource allocation robustness that take into consideration the influence of prolonging individual tasks on the stability of the schedule completed. Those measures make it possible to carry out a more precise analysis concerning the properties of the schedule with resource allocation in terms of its susceptibility to disruption in comparison to a flexibility indicator, flex, that has been applied so far in research.
