Realization of Safety Operation Management System using Information on Plant Life Cycle Activities

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，在过程安全管理相关知识和信息的维护方面还存在很多问题。在本研究中，我们提出了一些利用风险管理信息来支持PSM1的方法。为了开发安全运行管理系统的知识库，考虑了工厂全生命周期风险管理信息的获取和存储方法。通过对现有设计原理表示模型的扩展，提出了能够表示安全对策候选者、安全设计最终结果、选择安全对策的设计原理和简化信息检索系统之间关系的模型。此外，还提出了支持工厂异常情况下的变更管理和操作员决策的框架。基于符号DIREC…的故障诊断方法利用前面提出的过程控制信息，重新考虑了支持基于这些输出的一系列安全操作的信息流，并对运行支持系统的最佳框架进行了设想。并提出了支持相似故障事件与故障诊断相结合的计算机环境，通过参考存储为专有知识的技术专家来规划安全对策。提出了一种基于国际标准ISA-S88：间歇控制模型的间歇车间设计策略。该策略强调以安全联锁为基本部件的间歇控制系统的模块化。通过实例工厂的排序模型，明确了间歇工厂从设计到实施各阶段所需的信息，验证了ISA-S88的有效性。较少

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.
