基于工程决策的专家系统模型设计与研究

工程决策的影响因子和参数繁多且复杂,为提高工程决策的可用性和准确性提出基于工程决策的专家系统模型。模型根据现有数据模型结合实际需求,在关系数据内部形成知识支撑环境模型,采用框架和产生式规则相结合的方法,将推理过程与专家知识库结合,并提出一种综合评估方法为支持,辅助生产方案设计和措施调整。以油田实际生产现状为例,给出了相应油田异常井措施调整方案的推理过程,完成了模型的实例设计和实现,达到了提供辅助决策以提高决策可用性和准确性的目的。

Research and Design of Expert System Model Based on Project Decision

The impact factors and parameters of engineering decisions are complex and too much,to improve the availability and accuracy of engineering decisions,the expert system model based on project decision is proposed.According to the actual needs with existing data model,forming knowledge support environment within the relational data model,use the idea of combining the frame with production rules,present a integrated assessment method combined with reasoning and expert knowledge to obtain and analyze the production of information,support and measures to adjust the production design.And to the actual oil production status,for example,given the appropriate measures for oil wells abnormal reasoning process of adjustment programs,finished the example of the model.Reach to provide decision support with improving the availability and accuracy of decision-making purposes.
