【摘要】：本文针对基于工作流的科研过程管理系统进行研究,目的是将时间约束加入到科研流程中,使科研系统具有时间属性。虽然工作流技术可以简化业务流程的复杂性,但是并不完全地支持时间资源,使得时间资源在业务流程中不能被完全透视。时间资源是工作流的重要资源之一,工作流管理系统中时间资源利用问题是工作流研究领域的一大热门。本文将时间资源加入到科研过程管理系统中,并使用相关时间检测算法对科研流程进行时间分析。研究具有时间属性的科研过程管理系统,不仅具有重要的理论意义,而且具有广泛的实际应用价值。本文分析工作流技术在时间资源上的不足,结合已有工作流的时间管理成果,通过流程任务与时间资源绑定的方式,将时间资源引入到科研过程管理系统中;充分研究开源引擎Activiti,采用Activiti引擎提供的扩展方式,为流程中的任务添加时间约束,使得业务流程中每个活动都具有时间属性;添加时间管理模块,用来监控流程的运行情况、预期完成时间、任务的最小持续时间和最大持续时间等;流程建模,科研过程中的流程按照BPMN2.0标准进行流程定义,并部署在Activiti引擎中,采用基于关键路径的时间检测算法对科研过程中的流程进行时间分析。在流程管理中允许添加任务的预期时间约束,包括任务的预期截止时间和预期执行时间来支持业务流程时间计划的制定;采用模糊综合评价方法,通过直接产出成果、间接产出成果以及衍生效益这三个方面来完成对科研项目的综合评估。在此基础上,使用MVC设计模式以及Spring MVC、Mybatis和Spring三种Web开发框架设计并实现科研过程管理系统。
[Abstract]:In this paper, the research process management system based on workflow is studied. The purpose is to add time constraints to the scientific research process, so that the research system has time attributes. Although workflow technology can simplify the complexity of business processes, it does not fully support time resources, so that time resources can not be fully viewed in business processes. Time resource is one of the most important resources of workflow. The use of time resources in workflow management system is a hot topic in the field of workflow research. In this paper, time resources are added to the scientific research process management system, and the time detection algorithm is used to analyze the time of scientific research. The research process management system with time attributes is not only of important theoretical significance, but also has extensive practical application value. This paper analyzed the workflow technology in time resources, combined with the existing workflow time management achievements, through the process of task time and resource binding mode, the time resources into scientific process management system; fully research on the source engine Activiti, extended mode using Activiti engine provided by adding time constraints for the process in the task of making each activity in the business process has the attribute of time; add time management module, operation process, to monitor the expected minimum duration of task completion time, and the duration of the research process; process modeling, process flow is defined according to the BPMN2.0 standard, and the deployment of the Activiti engine, using the critical path time detection algorithm for time analysis on the research process in the process based on. The expected time allowed to add tasks in process management constraints, including task deadlines and expectations are expected to support the development of business process time plan execution time; using fuzzy comprehensive evaluation method, through direct and indirect output output and benefit derived from these three aspects to complete the comprehensive evaluation of scientific research project. On this basis, the research process management system is designed and implemented by using the MVC design pattern and three Web development frameworks of Spring MVC, Mybatis and Spring.
