Abstract

The invention provides a service flow network decomposition method, system and device based on a PN machine model and a medium. The decomposition method comprises the steps: constructing a PN model of a service flow network, and placing all transitions in the PN model in a transition set of undecomposed subnetworks, with the transitions being data processing states of the PN model, and each transition being provided with a subscript for representing a layer number and an inner serial number in each layer; and selecting the transition with the minimum subscript from the transition set of the undecomposed subnets as the initial transition, taking the transition of the transition set of the undecomposed subnets as the current transition, and searching the correlation between the preposition and the postposition of the current transition by synchronously processing the preposition and the postposition of the current transition so as to construct the concurrently executed service subnets. According to the invention, a complex large service processing network can be decomposed into a plurality of simple service sub-networks which can be executed concurrently, and the coupling between the service processing sub-networks is reduced while the concurrency capability is improved to the maximum extent.

Description
