Selection of sub-contractors of the project while minimizing settlements of contractual penalties and success fees

Most of today's projects are interdisciplinary and requires the involvement of contractors that specialize in different types of works. In various circumstances, it may be advisable to minimize their multiplicity or their diversification. In some cases it may be desirable to meet certain characteristics by contractors for selected tasks. The aim of this paper is to determine the model of selection of contractors in complex project from the point of view of the project owner or general contractor. As a methodological basis we use the multi-criterial decision model assigning each task to specific contractors in the project with the function of distribution of penalties arising from delayed completion and potential benefits in the event of early termination of the project.
