Functional-network model of tasks performance of the virtual communities life cycle directions

This paper presents the current problem of tasks performance of the life cycle directions of virtual communities. Nowadays, virtual communities form a unique content that is the actual source of information and its effective exchange. The analysis of virtual communities' creation as a project, organization of the life cycle is presented by using the network planning. The article presents the execution of tasks directions of the life cycle of virtual communities by using the functional-network model developed based on Petri nets. In this model, the top has a complex structure, what is the execution of the tasks direction, namely: user, informational, resource and reputational; and color the corresponding direction. Incoming flows of top containing incoming indicators for a start to execution of the tasks of direction formed in the previous stage, and output flows - formed new indicators of the tasks of direction to complete the next stage of virtual communities' life cycle.
