Substantiation of economic efficiency of an investment project, which involves both analysis and integrated estimation of the whole amount of available technological and financial information, should be considered as one of the most crucial and significant stages of pre-investment feasibility studies. For the process of creation and application of an investment project is a complicated dynamic process, it seems to be more convenient to use some computer-based mathematical simulation models in order to describe and estimate the above process. In this paper, the structure and the corresponding methods of calculation and evaluation of efficiency factors for the mathematical simulation models are considered and t hey are illustrated with an example of application of such methods to a mathematical simulation of an investment project connected with the setting up of a small hotel.

The proposed method provides an algorithm to calculate the minimal volume of resources, necessary for a communication channel under given requirements on the quality of network traffic service. The method is based on the information about joint communication channels and estimates of the traffic parameters. If a part of traffic is certainly known to be denied, this part should be eliminated from the network as early as possible. Although the provided method has been developed for the calculations on parameters of reserved communication channels, it can be applied for the planning in the network as a whole.
