摘要
引入知识工程与机器学习理论 ,以问题与事例的类似性分析为研究对象 ,以利用以往的建模经验知识和事例指导改进建模操作为突破口 ,提出实际应用问题基于知识的树状表示方法 ,从问题域、问题结构和数据信息三方面给出了问题与事例类似性的评价方法和类似度的计算公式 ,并对基于事例学习的建模方法及其建模支持系统进行了初步研究 .本项研究有利于促进和深化建模与模型管理的类人化、智能化研究 ,在动态系统的实时优化控制领域具有较广阔的应用前景 .
The studies by applying knowledge engineering theory the similarity evaluation between problem and case to identify ways to improve modeling with previous experience, knowledge and case in modeling, a knowledge-based tree-like representation for real problem and an evaluation method together with its formulae have been developed to calculate the similarity between problem and case in aspects of problem domain, problem structure and data information. A case-based learning modeling and its modeling support system have been studied in particular. Modeling and model management have been further studied with anthropoid and intellecturalization, which will be used widely in real-time optimal control for dynamic systems.
