过程仿真培训支持系统中基于知识的操作评价

本文以“过程仿真培训支持系统（ＰＳＴＳＳ）”为背景，分析了现有的计算机仿真培训器操作评价方面的不足，着重论述了ＰＳＴＳＳ评价支持子系统的设计思想与实现技术。首先，本文提出了用知识工程技术对学员操作水平进行评价的思路，然后通过对过程工业的分析，确立了评价支持子系统所采用的评价准则，建立了较全面、科学的评价指标体系，本文还介绍了知识表示。知识库组织与管理、推理机结构框架等具体实现技术。

Knowledge-based Operation Evaluation in Process Simulation Training Support System

Based on Process Simulation Training Support System ( PSTSS), after analyzing the defects of available simulation trainers on operation evalution, this paper lays emphasis on the design thoughts and implementation techniques of the Evaluation Support Subsystem (ESS). To begin with, the paper puts forth the idea to evaluate the operation level of trainers with knowledge engineering techniques, then, the criterions and a more comprehensive and more scientific system of indexes for evalution are provided according to the characteristics of process industry. Finally, the paper also introduces the realizing techniques on kownledge representation, organization and managernent of the knowledge base, stuctural framework of the inferor.
