Embodiment Construction

[0016] exist image 3 In , a simple workflow graph based on the node deadline mechanism DAG representation of the process flow belt is shown. In the DAG graph, the activities located in the same path are executed serially, and the completion time is the sum of the execution time of all activities, and is subject to the priority multi-active page constraint. Therefore, if one of the activities chooses a lower-level service to execute, other activities will choose a higher-level service due to deadline constraints, that is, the service selection of these activities (essentially the time allocation for each activity) affects each other , which gives the following (1) Given G=(V, E), time-priority multiple active pages must be located on the same path. For j, the predecessor activity r is called j's forward time-priority multi-leaf activity; for r, the successor activity j is called r's backward time-priority multi-leaf activity. (2) Given G=(V, E), its maximum forward time prio...

Abstract

The invention discloses a node deadline mechanism based on a process flow band. The workflow is regarded as a heterogeneous workflow; Shared computing resource pool, under the condition that the service resources are enough and parallel tasks can be executed simultaneously, the resources are saved. The operation process is automatically executed according to the circulation in the development process; According to the embodiment of the invention, a node deadline mechanism based on a process flow band is provided, several processes are automatically initiated, and the processes are in parallelindependent flow and also have a priority association process which influences whether a main process reaches a next link or not. Thus, on one hand, a flexible and convenient operation interface is provided for a system administrator, and on the other hand, synchronous exchange and sharing features of data are more popular with users, the system can be effectively helped to simplify redundant processes, and the method is the development direction of the future workflow technology.

Description

technical field [0001] The invention relates to the field of automation technology under the computer application environment, in particular to the business process of automatic execution according to the flow in the development process, which transfers and executes documents, information or tasks between multiple loose pages. Background technique [0002] Workflow, the concept originated in the fields of production organization and office automation, is a concept proposed for activities with fixed procedures in daily work. Perform these tasks and monitor them to improve work efficiency, better control the process, enhance customer service, and effectively manage business processes. The workflow definition given by Georgakopoulos is: a workflow is a group of tasks organized to complete a certain business process: the trigger sequence and trigger conditions of the tasks are defined, each task can be completed by one or more software systems, or can be It is done by one or a ...
