Abstract
The main goal of dispatching strategies is to minimize the total time for processing tasks at maximum performance of the computer system, which requires strict regulation of the workload of the processing units. To achieve this, it is necessary to conduct a preliminary study of the applied model for planning. The purpose of this article is to present an approach for automating the investigation and optimization of processes in a computer environment for task planning and processing. A stochastic input flow of incoming tasks for processing is considered and mathematical formalization of some probabilistic characteristics related to the complexity of its servicing has been made. On this basis, a software module by using program language APL2 has been developed to conduct experiments for analytical study and obtaining estimates of stochastic parameters of computer processing and dispatching. The proposed model is part of a generalized environment for program investigation of the computer processing organization and expands its field of application with additional research possibilities.

In the general case, computer processing is a set of procedures performed on data streams
The organization of the planning of parallel processes is directly related to the abstract description of the processes themselves and formalization of the hierarchical structure of the algorithms generating them, as well as to the correct description and definition

Summary
Computer processing is a set of procedures performed on data streams. The purpose of this article is to present an approach for automating the investigation of the processes of processing information units, arriving as a stochastic flow of service requests to processor devices For this reason, a program module developed using the TryAPL2 system on the basis of preliminary formalization and mathematical modelling is presented. The present work should be considered a continuation of the research done in [1], and aims to present an addition to the developed set of modules for mathematical modelling of computer processing For this reason, the organization of the model investigation is made on the basis of the procedure presented in [1], performing consistently the phases provided in it: goal defining; preliminary formalization of the object of study; mathematical modelling; program realization; conducting experiments; results analysis.
