油藏数模专家系统中的知识动态调度

油藏数值模拟历史拟合辅助专家系统的开发是一个增量式的开发过程,随着系统功能的日趋增强,知识库也将不断求精不断扩充,根据求解问题的不同,可能形成若干知识块。介绍了油藏数值模拟历史拟合辅助专家系统中为满足系统功能不断完善的需求,而建立的知识动态调度机制。改造后的Clips系统,推理方式采用在推理过程中根据当前的状态动态地选择规则和事实进行推理的机制,以及推理服务对象与ODBC接口,实现调度存储在各种异构数据库中的规则和事实,同时,为研究和开发多专家系统打下了基础。

DYNAMIC DISPATCH OF KNOWLEDGE IN RESERVOIR NUMERICAL SIMULATION EXPERT SYSTEM

The development of the assisted expert system for the history matching of reservoir numerical simulation is a process on the increase. The knowledge base is going to be proficient and expanded with the improvement of system function, the blocks of the knowledge can be formed in the light of the different solutions. This paper describes the dynamic dispatch mechanismof knowledge for consummate of the assisted expert system for the history matching of reservoir numerical simulation. In the modified clips system, the inferential mechanism is that the rules and facts are chosen into inferential machine dynamically according to present status during inference; the ODBC interface of the inferential service object is made to dispatch rules andfacts stored in many heterogeneous databases. In the mean, the foundations of the research and development for multi-expert system is built.
