Process control method and process engine

Abstract

The invention relates to the technical field of computers, in particular to a process control method and a process engine. The process control method includes the steps that an instantiation request is received, wherein the instantiation request comprises a first activity to be performed; instantiation is performed on the first activity to be performed, wherein an execution condition of the first activity to be performed and a subsequent activity after the first activity to be executed is executed are pre-allocated in the first activity to be performed, and the subsequent activity is a second activity to be performed or a stop instruction; whether the first activity to be performed meets the execution condition or not is judged, if the first activity to be performed meets the execution condition, the first activity to be executed is executed, and an execution result is generated; the subsequent activity is selected according to the execution result; the subsequent activity is sent to an activity information bus, and the activity information bus sends activity completion information to a user or an automat according to the stop instruction. According to the process control method and the process engine, the control flexibility is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, to a process control method and a process engine. Background technique [0002] The process engine is an important part of the system process control. The process engine includes basic objects and services, as well as the call and execution mechanism. The call and execution mechanism is used to call and run the objects and services in the engine to complete a certain business. [0003] like figure 1 As shown, the sequence when the existing process engine executes the process is: step 101, the process engine receives the process execution command initiated by the user, and the process execution command includes the target queue; step 102, the process engine initiates the target queue execution command to the business process, The business process includes all processes to be executed. After the business process receives the execution command of the target queue, step 103 ...

Problems solved by technology

[0004] However, in the above process control process, the entire process is used as the smallest management module. When starting a process, the complete process needs to be instantiated before execution

And when each activity is executed, state control and process scheduling are carried out for the activities that have been executed and the activities that have not been executed. If any activity in the process is changed, all the activities in the instantiated process must be executed according to the original definition , cannot be adjusted in time according to the changed activities, reducing the flexibility of control
