Countermeasures in Integrated Model of I&C Systems and Human Operators

Abstract

Reliability and risk issues related to the development of an integrated model of I&C systems and human operators in large-scale systems are discussed in Chapter 10. The development of an integrated model that address these issues is discussed in this chapter. I&C systems and human operators are completely different entities by nature. However, both I&C systems and human operators process information. I&C systems gather information from the plant and processes it to provide automatic control signals to the plant. I&C systems also provide information to human operators in a form that human operators can understand. Human operators receive the information from I&C systems and process it to provide manual control signals for I&C systems. The way information is processed in I&C systems is generally known, while the way information is processed by human operators is not well known. The development of an integrated model of I&C systems and human operators starts from the development of a model for how human operators process incoming information, especially during abnormal or emergency situations.
