Abstract
This study reviews simulation modelling of the heterogeneous distributed information processing systems. The relevance of simulation modelling for the considered class of systems is substantiated. The purpose of the study is outlined and solutions of the tasks required for its achievement are described. Based on the structural modelling carried-out earlier, main types of the model elements and the relations between them are allocated. The network structure generation algorithm is presented. The behaviour and the structure of model elements are described. Results of the modelling are displayed. At the conclusion, the possibilities for further development of the model are considered, and the conclusion on its practical application for real systems is made.
Highlights
Heterogeneous distributed information processing systems (HDIPS) are too complex for the analysis and implementation of tests in the actual practice, analysis thereof cannot be done without modeling
In the HDIPS simulation model, elements of several types are used: Requestors which imitate occurrence of an event which requires the computation and delivery of information to the decision-maker, they correspond to the sources of primary data in the structural model
When the HDIPS utilization information is received from the utilization database, the route is computed for each of the tasks in the wait queue: a
