For the queueing systems (QS) with «warm-up» a software package has been developed, which enables the calculation of the probability-time characteristics based on the intensity matrix of transitions between microstates of the system. A distinctive feature of the complex is the use of the input data in a matrix form, providing versatility in the analysis of different classes of QS.The paper describes the structure and functions of the complex, as well as the cross-testing results obtained for models with «warm-up» and approximated by two-phase hyperexponential distribution and two-phase generalized Erlang distribution. Software package allows to improve the accuracy of the probability-time characteristics by taking into account the influence of the «warm-up». The package is also applicable for the calculation of probability-time characteristics of other classes of QS. Favorable package features are complex integration capabilities for programmers and use of multi-Markov queuing in calculations.
