【摘要】：产品数据管理(Product Data Management,PDM),是一种用来管理产品数据的新技术。PDM技术实现了对产品数据的有序化、结构化管理。PDM技术管理与产品相关的两个方面:一方面是信息,这些信息包括产品的设计概念,结构修改,存档数据等等;另一方面过程:包括整个产品生命周期内的审查、批准、版本变更等过程。工作流管理技术是将业务分为了任务与角色两个方面,然后将任务和角色通过一定的规则和过程联系起来,并且对业务流程进行监控,从而达到提高工作效率的目的。PDM系统中的工作流对与产品相关的流程进行管理,管理流程中产生的数据与编辑、审查与批准等过程。因此,工作流在PDM系统中处在核心地位。时间是工作流管理中的一个重要因素。时间可以支持和加强工作流系统的柔性,使得工作流系统有较强的鲁棒性。工作流时间管理研究的是工作流的时间维计划。时间管理设定活动节点的起止时间、监控工作流执行情况,处理时间违反触发的异常,从而保证了工作流执行效率,也确保了产品质量和产品能够被及时推向市场。本文作者分析了时间管理在PDM系统的工作流中实施的必要性,同时指出了工作流在PDM系统中管理的内容,之后在本实验室PDM项目实际需求基础上,对工作流实例进行了初始化,基于时延Petri网理论设计了一套时间管理体系,最后将工作流实例运行通过甘特图展示出来。本文的重心在基于时延Petri网理论工作流时间管理体系的建立以及工作流执行在甘特图中的展示,为企业提供简单有效实用的工作流时间管理机制。
[Abstract]:Product data management (Product Data Management (PDM)) is a new technology used to manage product data. PDM technology realizes the orderly and structured management of product data. PDM technology management and product related two aspects: one is information, which includes product design concept, structural modification, archival data and so on; on the other hand, process: including the whole product life cycle review, approval, version change process. Workflow management technology divides business into two aspects: task and role, then links tasks and roles through certain rules and processes, and monitors business processes, so as to achieve the goal of improving work efficiency. The workflow in the PDM system manages the process related to the product, manages the data produced in the process and the process of editing, reviewing and approving. Therefore, workflow is at the core of the PDM system. Time is an important factor in workflow management. Time can support and strengthen the flexibility of workflow system, which makes the workflow system more robust. The study of workflow time management is the time dimension plan of the workflow. Time management sets the start and stop time of the active nodes, monitors the execution of the workflow, and handles the time to violate the triggered exceptions, thus ensuring the efficiency of the workflow execution, and ensuring that the product quality and products can be timely introduced to the market. In this paper, the author analyzes the necessity of the implementation of time management in workflow PDM system, and points out the workflow in PDM system management, after the project PDM of the laboratory actual demand, the workflow instance initialized, timed Petri net theory to design a time management system based on the last show out of workflow instance running through the Gantt chart. The focus of this paper is the establishment of Workflow Time Management System Based on time delay Petri net theory, and the presentation of workflow execution in Gantt chart, so as to provide a simple and effective workflow time management mechanism for enterprises.
