【摘要】：近些年,随着信息化水平的发展,电子政务已经成为了国家政府实施政府职能转变、提高政府管理、公共服务和应急能力的重要举措,它关系到整个国民经济和社会信息化的发展。目前我国电子政务虽然实现了无纸化办公,但在政府业务办理和公众服务方面还存在着不足。由于传统政务系统的强耦合性,面对复杂多变的业务需求不能实现动态扩展,办公效率显得极其低下。为解决上述问题,本文利用Activiti技术平台为政府部门提供计算机程序环境,为政务网站的实施、维护及管理、应用服务提供了保障。本文的主要研究内容如下:(1)对Activiti技术的总体框架进行详细介绍,提出一套支持业务流程一体化操作的建模元模型,对元模型结构进行定义和解析,并给出了元模型编码算法和处理错误机制,改进基于规则算法以动态修改工作流。最后对模型编码算法和执行规则迭代算法进行仿真实验,得出了元模型结构和改进规则迭代算法的有效性和准确性,从而提升了工作流的动态适应性。(2)针对X市国土资源政务办公的需求,整合Activiti工作流技术开发出了一套适合自身需要的可定制政务审批系统。首先将对可定制的政务系统进行需求分析和数据库设计,在系统实现方面详细讲述了系统可定制的特色,包括流程定制、表单定制、业务类型定制等。在业务生成层,使用Activiti的Web流程设计器进行流程自定义配置的操作,可以上传流程定义文件(需要遵循BPMN2.0规范)进行流程的初始化,减去在系统中一步步操作的麻烦。最后给出流程实例和系统部分界面实现。
[Abstract]:In recent years, with the development of information technology, e-government has become an important measure for the national government to implement the transformation of government functions, improve government management, public services and emergency response. It is related to the entire national economy and the development of social information. Although e-government in our country has realized paperless office, there are still shortcomings in government business management and public service. Because of the strong coupling of traditional government system, the office efficiency is extremely low in the face of complex and changeable business requirements can not achieve dynamic expansion. In order to solve the above problems, this paper uses Activiti technology platform to provide computer program environment for government departments, and provides guarantee for the implementation, maintenance and management of government websites and application services. The main research contents of this paper are as follows: (1) the general framework of Activiti technology is introduced in detail, and a set of modeling metamodel supporting integrated operation of business process is proposed, and the structure of metamodel is defined and analyzed. The meta-model coding algorithm and error handling mechanism are given, and the rule-based algorithm is improved to dynamically modify the workflow. Finally, the model coding algorithm and execution rule iteration algorithm are simulated, and the validity and accuracy of the meta-model structure and improved rule iterative algorithm are obtained. Therefore, the dynamic adaptability of workflow is improved. (2) according to the demand of land and resource government affairs office in X city, a customizable government approval system is developed by integrating Activiti workflow technology. Firstly, the requirement analysis and database design of the customizable government system will be carried out, and the characteristics of the system customization, including process customization, form customization, business type customization and so on, will be described in detail in the implementation of the system. In the business generation layer, Activiti's Web process designer is used to customize the process configuration, which can upload the process definition file (which needs to follow the BPMN2.0 specification) to initialize the process, minus the trouble of operating step by step in the system. Finally, an example of the process and the implementation of some interface of the system are given.
