基于Petri网和定制技术的油田档案管理系统设计

Design and Implementation of Oilfield Archive Management System Based on Petri Net and Custom Technology

针对油田数字化档案馆中的系统模块化程度低及灵活性差等问题,提出基于Petri网和组件技术的功能定制开发方法。采用面向对象着色Petri网实现档案管理的层次化建模,并添加复位弧优化档案调用流程。利用关联矩阵和可达图及相关理论,对模型进行合理性分析。通过模型提取组件,建立组件信息库。利用信息库结合用户定制的业务逻辑,实现系统对组件的有序调用,完成业务定制功能。应用结果表明,该系统定制灵活、适应性强、档案调用速度快,满足实际需要。

The development method of functional customization based on Petri net and component technology is proposed, aiming at the problem of low modularization and flexibility of the system in the digital archives of oil field. The object-oriented colored petri net is adopted to realize the hierarchical modeling and the reset arc is added to optimize the workflow of the archives＇ invocation. The rationality of the model is analyzed through the correlation matrix and the reachable graph and the other related theory. The component information base is built by the model＇s extraction. The components are called in order and the custom function of business is completed by using information base and business logic of customers. In the application, the system is flexible, adaptable, the file transfer speed is fast, and the needs has been met in the actual application.
