Most of conventional operation support system has designed for only specific process plant and still there is much issue on maintenance of knowledge and information related to process safety management (PSM). In this study, we have proposed some methods which use the risk management information for supporting the PSM.1. To develop knowledge-base for safety operation management system, the methods of acquisition and storage of risk management information through the plant life cycle have been considered. By extending the existing representation model of design rationale, model which can represent the relationships among candidates of safety countermeasures, final result of safety design, design rationale for selecting it and simplified information search system have been proposed. Furthermore, framework for supporting the management of change and the operator's decision making at plant abnormal situation have been also proposed.2. For the fault diagnosis method based on the signed direc … More ted graph and the operation decision method for the plant abnormal situation using the information on process control which have been proposed previously, information flow to support the series of safety operation based on these outputs have been reconsidered and the best framework of operation support system has been contemplated. And computer environment which can support the integration of the the similar trouble event with the fault diagnosis and the planning the safety countermeasure by referring the technical expertise stored as know-how has also been proposed.3. A design strategy for batch plant based on the model of international standard, ISA-S88: batch-control, is proposed. The proposed strategy emphasized the modularization of batch control system consisted of safety interlocks as the primitive component. Through the ranking models of a practical example plant, necessary information at each stage from design to implementation of batch plant has been clarified, and the availability of ISA-S88 has been verified.

传统的操作支持系统大多是针对特定的过程工厂而设计的，在过程安全管理知识和信息的维护方面存在很多问题。在这项研究中，我们提出了一些方法，使用风险管理信息支持PSM。为了开发安全运行管理系统的知识库，考虑了在整个生命周期中获取和存储风险管理信息的方法。通过扩展现有的设计原理表示模型，提出了一种能够表示安全对策候选方案、安全设计最终结果、选择安全对策的设计原理以及简化的信息检索系统之间关系的模型。此外，还提出了在异常情况下支持变更管理和操作员决策的框架.对于基于符号方向的故障诊断方法， ...更多信息 ted图和利用过程控制信息的电厂异常运行决策方法，重新考虑了基于这些输出的支持一系列安全运行的信息流，并设想了运行支持系统的最佳框架。并提出了一种计算机环境，该环境可以支持类似故障事件与故障诊断的集成，并通过参考存储为专有技术的技术知识来规划安全对策.提出了一种基于国际标准ISA-S88：间歇控制模型的间歇过程设计策略。该策略强调了以安全联锁为基本元件的批处理控制系统的模块化。通过实例的排序模型，阐明了间歇过程从设计到实施各个阶段所需的信息，验证了ISA-S88的有效性。少
