Description: The article provides information on software (software), within which a model of the processes of resource allocation and replenishment of the resource (RDP) of the grouping of technical objects is implemented. First, the PRVR model itself is briefly described, which is intended for forecasting the composition and resource of the grouping at a given in terval of its operation time. The parameters of the model are: – the state of the grouping at the current time; – normative indicators of the resource of objects and parameters that determine the process of replenishing their resource when they are used in the composition of this grouping; – expected average intensity of resource consumption of objects; – plans for repair, write-off (termination of operation) and delivery to the grouping of new facilities. The PRDP model is realized by the simulation method in Delphi programming language. For a better understanding of the way the model is implemented, a brief description of the classes of program objects that form the basis of modeling algorithms is given. The developed software is not just an implementation of the PRCM model, but is a software system that, on the one hand, allows generating different variants of groupings and investigating their properties and features, and on the other hand, it provides an opportunity to solve the tasks of forecasting the composition and resource for specific groupings specified by the user. For this, a built-in (integrated into the program) database (DB) is u sed. Forecasting composition and resource grouping can be carried out in one of the following modes: (a) "regulatory planning", when plans for repair, write-off and delivery of new objects are implemented in strict accordance with the standards established for this grouping, and (b) "user planning" When all actions to replenish the resource are carried out according to the plans set by the user. A brief description of the user interface of the software is provided. Examples of simulation results are given.
