Abstract

In work it is offered the analysis of resource-intensive costs of computing implementation procedures in realization of gas dynamics problems. The analysis is carried out for the computer model using the modified method of Petrov-Galerkin and Gryunvald-Letnikov's scheme for fractional derivants on time. Numerical experiments were made on the composite network systems from the GTS elements. It is investigated communications between parameters of adaptation of mathematical model. Paths of time optimization in computing procedures are offered.
