One of the most important problems that arise in the realization of any project and especially complex projects is contractor choice optimization of all its activities. The term choice optimization presumes the selection of such contractors that will perform their activities, and thus the whole project, on schedule and at minimum cost. This paper analyzes these problems in detail and shows how they can be presented using models of combinatorial parametric optimization. Since the majority of algorithms for resolving these models is inconvenient for practical application, this paper recommends a modified PERT-COST algorithm for cost minimization of project realization based on its lead time.

The previous limit the role of government and its suppression at the expense of other (private) actors led to a more pronounced difference between all classes of people. On the one hand we have the poorest people, who do not have even the minimum for survival, indebted middle class and new (old) class over-rich who use any means to make a profit. The aim of this paper is that through the prism of neoliberal ideas review the roots of the global economic crisis and the effect that has on the world.
