“…It is important to analyse the methods of problems solving using services in a distributed computing environment, and it is necessary to create a modelling apparatus that allows a comprehensive description of complex processes and to draw qualitative conclusions about the behaviour of the systems in question [ 2 , 7 , 8 ].…”

In this paper, we consider the existing problems of colour stochastic Petri nets (CSPN) for modelling of systems of interconnected applications - services. The main issues that arise when modelling service applications and their interactions are as follows: support of composite types and indexed arrays, describing operations on top of them. It is also important to note the problem of using global time in model combinations – it is hard to describe different levels of abstraction. For example, to combine the network behaviour such as delays, duplication, and packet loss and its effects on business logic. To solve all of these problems, we propose a new model of a service-oriented Petri net (SOPN). It is built based on the stochastic Petri net (SPN) by adding some restrictions and extension components. We added tools for creating data structures, fundamental types such as integers, rational numbers, ordered arrays. The model presented in this paper provides the toolkit for creating complex atomic operations in terms of model-controlled time. Meanwhile, for all the new components and features transition to the basic SPN model is supported.
