The EPC theory. Couplings between transitions in enterprise process control systems
The paper is the second one of publications on the EPC theory. Relationships between transitions and activity transition units, as well as definitions of functional and control transitions of the framework EPC system, have been presented in it. Then classification of transitions by their attribution to different functional layers and data processing phases in EPC systems has been shown. The resource inputs and outputs have been defined for functional and control transitions. System couplings, as well as input and output resource couplings, between functional and control transitions have been defined by analogy of correspondingcouplings between functional and control units. Tight relationships between structures of an enterprise management system and a corresponding information system have been presented. These are relationships between the structure of associations of functional and control units with information places and the structure of analogous associations of transitions with places. Next, couplings of central coordination transition with local transitions of horizontal coordination have been discussed. On these grounds the notion of a distributed process has been introduced and the definition of a business process has been specified.
