A state machine workflow engine based on scxml standard

Abstract

The invention relates to a state machine workflow engine based on an SCXML standard. The state machine workflow engine comprises a process resolver, a task dispatcher, an instance manager and a multi-state machine event repeater, wherein the process resolver is used for resolving process definition files; the task dispatcher is used for dispatching tasks specified in the process definition file to corresponding resources; the instance manager is used for managing all state machine workflow instances; and the multi-state machine event repeater is used for receiving events sent by the state machine workflow instances in an operation process, and delivering the events to the corresponding state machine workflow instances by searching a state machine instance tree of a source state machine workflow instance. The workflow engine provided by the invention not only has the task dispatching capability of a traditional workflow engine, but also has the event forwarding capability, can be used for improving the asynchrony between the instances, and can provide support for complex collaborative processes during operation.

Description

Technical field [0001] The present invention relates to the field of workflow and state machine, and more specifically, to a state machine workflow engine based on the SCXML standard. Background technique [0002] Workflow technology was first applied to the transmission of documents within enterprises. With the development of the times, workflow technology has been widely used in inter-organizational collaboration, e-commerce, and administrative management among enterprises. In recent years, the vigorous development of the Internet has put forward new tests on how to use workflow technology to solve business process problems with a series of new characteristics. Traditional workflow engines do not support the execution of complex collaborative processes in the network society. In this case, there is an urgent need for a workflow engine that can support the execution of complex collaborative processes. [0003] Finite state machines (FSM) are widely used in digital circuit design...

AI Technical Summary

Problems solved by technology

[0003] Finite state machine (FSM) is widely used in digital circuit design, game development, single-chip microcomputer development, program design and other related fields. However, with the increase of application complexity, FSM has gradually exposed its own shortcomings: once the state and The number of transfers increases, and state explosions are inevitable

These engines do not support sub-processes enough, and lack information sharing between process instances, which makes them unable to support the execution of complex collaborative processes.
