Power production control system is very important in the power system. In paper, a new method of risk assessment for power system based on rough set theory, fuzzy mathematics and Bayesian network(BN) is presented. Though fuzzy cluster the influencing factors of risk by using compatibles fuzzy rough set, making the minimum risk feature class as a BN node, which can effectively reduce the complexity...
This paper introduces the gray clustering theory as a method to conduct an information security risk assessment for power substation communication systems using the gray theory with combination of AHP and Delphi method, and improves the substation communication system information security risk assessment model based on the gray clustering theory. Analysis albino gray clustering by constructing weight...
Cyber Physical System (CPS) is a combination of physical systems with cyber systems, where there is a tight coupling between the two systems. It is widely used in critical national infrastructure, such as electric power, petroleum and chemical industries. Once an attack against the CPS obtains success, the consequence will be unimaginable. A well-designed risk assessment of CPS will provide an overall...
In contemporary society, with supply chains becoming more and more complex, the data in supply chains increases by means of volume, variety and velocity. Big data rise in response to the proper time and conditions to offer advantages for the nodes in supply chains to solve prewiously difficult problems. For any big data project to succeed, it must first depend on high-quality data but not merely on...
