摘要:工作流是现代控制与自动化的一个新的研究领域,它依托工作流引擎以及相应的软硬件平台来实现信息的自动传递与处理。作为工作流引擎的重要组成部分,调度算法直接管理工作流模型中各个元素的状态以及状态的变化。因此,调度算法的设计与工作流模型本身具有密切的关系。本文首先介绍了针对非生产性质的工作流平台多步任务协同网(Multi-step Task Collaborative Net)的基本概念以及定义,包括角色,工作,任务,转发,分组以及循环。在此基础上,详细介绍了相应的调度算法,包括启动案例,终止案例,角色签办任务,角色退回任务,多步任务办理,任务重办,启动循环,终止循环。最后,以一个实际案例对算法的有效性进行展示。

Scheduling Algorithms for MSTC Nets
Abstract:Workflow is a new research area of modern control technology and automation, which is based on workflow engines and corresponding software and hardware platforms to realize the information transmission and processing. As an important part of workflow engines, scheduling algorithms directly manage the elements’ states and their transmission in the workflow models. Therefore, the scheme of scheduling algorithms is closely related to the model it is based on. Firstly, this paper introduces the basic concepts and definition of MSTC (Multi-step Task Collaborative) net systems, which include roles, works, tasks, delivers, groups and loops. Then, the detailed scheduling algorithms based on MSTC net systems are presented, including case launch, case termination, sign-in by roles, sign-out by roles, execution of multi-step tasks, task redoing, loop launch and loop termination. Finally, a practical case is presented to show the effectiveness of the algorithms.
