Developement of a Consultant System for the Operation at the Emergency of the Chemical Plant

为了指示需要检查的位置，开发了化工厂紧急操作的领事系统。候选故障的起因和应采取的操作措施。开发工作按以下步骤进行：(1)确定用于表示化工厂操作的必要且充分的单词和句子结构集合。(2)确定知识和数据库的结构，以表示目标对象运行和状态变化之间的关系。(3)准备工具，通过对话方式辅助建立知识和数据库。该系统已在一台个人计算机上实现，用于醋酸生产过程中的氧化反应子过程。模拟氧化反应子过程中的紧急情况，通过连接构建在另一台个人计算机上的模拟器，证明了该咨询系统的有效性。

A consul tant system for the operation at the emergency of the chemical plant has been developed in order to indicate positions to be checked. Candidates for the origin of failure and operations to be purformed. The developement has been carried out according to the following steps; (1) determination of the necessary and sufficient sets of words and sentence structures for the representation of operations of chemical plants. (2) determination of the structures of knowledge and data bases to represent the relationships between operations and changes of states of the objective plant (3) preparation of the tool to assist to make knowledge and data bases through interlocutive modes. A prototype of this system has been made on a personal computer for the oxidation reaction subprocess of the acetic acid manufacturing process. Simulations of emergencies in the oxidation reaction subprocess demonstrated the usefulness of this consultant system by connecting the simulator constructed on another personal computer.
