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.

We investigated the effects of sexual reproduction on vegetative propagation and relative somatic cost in Arum maculatum L. (Araceae). Two groups were selected as control and experimental. The spadices of individuals in experimental group were removed to test the relationship between sexual reproduction and vegetative propagation. Statistically significant differences were found between initial and final tuber weight in individuals with sexual organs removed. No significant differences were found between initial and final tuber weight in naturally reproducing (sexual organs not removed) individuals. However, the statistically significant differences were found between control and experimental group with respect to above-ground biomass but not in terms of below-ground biomass. The differences between two groups in terms of above-ground and below-ground nitrogen concentrations were also significant. Relative somatic cost of sexual reproduction (RSC) was observed in above-ground parts, but not in below-ground parts in terms of biomass and in both above- and below-ground parts in terms of nitrogen concentration.
