SYSTEM MODEL OF COMMUNICATION PARTICIPANTS 'COMMUNICATION PROCESSES

The subject matter of the article is the stakeholder’s communication processes of infrastructure development projects. The goal is to develop a formalized systemic model of the communication processes interaction between project stakeholders and project team in a virtual office environment. The following methods are applied: systemic analysis, set-theoretic models. The article solves the following problem: the basic communication management terms defined, the communication types defined, existing communication models analyzed, stakeholders communication processes set-theoretic systematic model developed. The following results are obtained: project management communication processes were analyzed; the project communication processes between stakeholder’s importance was demonstrated; communication process content and term were defined; fundamental project communication processes, that are necessary for the timely and correct project data generation, collecting, distribution and saving, were defined; project communication processes were classified, by assessing existing project management systems; project communication management stages and centralized/decentralized communication structure types were defined; fundamental linear/non-linear project communication processes were examined; communication processes modeling and formal application were analyzed; 3-component communication system model was proposed; proposed communication model characterized the communication act sequence and consist of a set of vertices - communication acts and connecting edge set, what shows the ability to move from current act to the next one. Conclusions: Formalized communication model as a system model gives the ability to solve the time optimization and security problems of the project virtual offices. Particular activities and communications of the general project tasks set, where the project team and other stakeholders simultaneous cooperation is required, should be taken into account.
