The paper presents the possibility of application of stochastic methods in supporting the selection of project team members. According to research of M. Belbin an effective collaboration of members of the project team requires 8 team roles (describing the soft skills) in its composition, which will enable the occurrence of the synergy effect. For the purpose of the reasearch, the original software was developed, which uses stochastic methods in the process of assembling teams that meet these criteria. The paper presents the results of experiments based on anonymized surveys conducted among students of different faculties. Teams obtained thorough conducted simulations fulfilled the criterion of completeness of team roles.It was pointed out that the use of stochastic methods in supporting the process of selection of employees in project teams may contribute to improving the efficiency of resource allocation through the appropriate assignation of roles and responsibilities, for example, to avoid a situation where a qualified professional would be attached to the team, wherein his potential would be wasted.

This paper shows the results of analyzing the effectiveness and efficiency of a hybrid approach against a variety of optimization problems. An application with a serial-optimization structure, consisting of several methods with different characteristics, is presented. In order to evaluate the initial effectiveness of the hybrid optimization method, a number of test tasks, represented by complex functions with many variables, were examined. Additionally, a real-life case, determining an optimal product variety in a supermarket environment, regarding the highest rate of return for given conditions and limitations, is presented as an instance of the practical use of a hybrid algorithm. The research shows that the results achieved by the hybrid- -optimization method are highly satisfactory, both in terms of efficiency as well as effectiveness.
