Average case analysis of the set packing problem

The paper deals with the well known set packing problem and its special case, when the number of subsets is maximized. It is assumed that some of the problem coefficients are realizations of mutually independent random variables. Average case (i.e. asymptotical probabilistic) properties of selected problem characteristics are investigated for the variety of possible instances of the problem

Personality in project management methods

High work efficiency is required by today’s organizations. Besides of other factors it depends on the right allocation of employed workers to their duties. Assigning employees to the right activities isn’t an easy task, because the job efficiency and differences in human nature have to be considered simultaneously. Usually, the decision undertaken by the human resource (HR) manager is based on his subjective experience. In several cases, such solution results in negative reactions of employees, and may lead to conflicts occurrence. In order to avoid them the problem of allocation of the properly selected team (taking into account workers’ personality) to the project’s activity is of crucial importance. Its right solution can decrease risk of activity execution delay. So, it is assumed the project’s completion time depends both on physical and psychological features of employed workers. Experimental results presented illustrate this approach
