A hierarchical fuzzy logic systems frame work for data security

International Journal of Information Technology, 2017
Data security and privacy plays a key role in carrying out day to day and long term business operations successfully. Organizations need to protect their data in the areas of data security and privacy. Therefore data security and privacy is a significant activity for large organizations.

Fuzzy Logic Algorithm of Ecological Forest Zoning in the Vicinity of Chemical Plants Based on a Hierarchical System of Fuzzy Composite Indices

Theoretical Foundations of Chemical Engineering, 2021
A hierarchical system of fuzzy composite indices calculated for natural forest levels is put forward. For each of the levels, its own composite index (CI) is calculated, which is further used to calculate the higher level generalized composite index (GCI).

A method of converting conventional fuzzy logic system to 2 layered hierarchical fuzzy system

The 12th IEEE International Conference on Fuzzy Systems, 2003. FUZZ '03., 2004
To solve the rule explosion problem in a multi input fuzzy logic system, a method of converting a given fuzzy system to a 2 layered hierarchical fuzzy system is presented where the collection of the THEN-parts of the fuzzy rules of given fuzzy system is considered as vectors of fuzzy rule.

Design of a hierarchical fuzzy logic PSS for a multi-machine power system

2007 Mediterranean Conference on Control & Automation, 2007
The performance of fuzzy-logic power system stabilizer (FPSS), which is tuned automatically as the operating conditions of power system change, is investigated by applying it to a multi-machine power system. FPSS is developed using speed deviation and the derivative of speed deviation as the controller inputs variables.

A mathematical formulation of hierarchical systems using fuzzy logic systems

Proceedings of 1994 IEEE 3rd International Fuzzy Systems Conference, 1994
In this paper, we use fuzzy logic systems to model higher levels of hierarchical systems. Specifically, we consider three-level hierarchical systems where the lowest level comprises the plant and convertional feedback controllers, the middle level performs supervisory operations to guarantee the stability of the whole system, and the top level is a ...

Decomposition and hierarchical control for discrete complex systems by fuzzy logic controllers

2009 6th International Multi-Conference on Systems, Signals and Devices, 2009
This paper proposes a method to compute sub-optimal control strategies of discrete time large-scale non-linear systems by fuzzy logic controllers. The method is based on the principle of decomposition of the global system into inter-connected subsystems. We consider that the non-linearities are located in the interconnections terms.

Designing Unsupervised Hierarchical Fuzzy Logic Systems

2009
Systems such as robotic systems and systems with large input-output data tend to be difficult to model using mathematical techniques. These systems have typically high dimensionality and have degrees of uncertainty in many parameters. Artificial intelligence techniques such as neural networks, fuzzy logic, genetic algorithms and evolutionary algorithms

Modelling, Control and Prediction using Hierarchical Fuzzy Logic Systems

International Journal of Fuzzy System Applications, 2017
Hierarchical fuzzy logic systems are increasingly applied to solve complex problems. There is a need for a structured and methodological approach for the design and development of hierarchical fuzzy logic systems. In this paper a review of a method developed by the author for design and development of hierarchical fuzzy logic systems is considered. The

A Hierarchical Fuzzy Logic Control System for Malaysian Motor Tariff with Risk Factors

2016
In many countries, including Malaysia, it is made compulsory to have a motor insurance policy and the premium is determined based on the Motor Tariff which ensures that a standard premium is imposed to the policyholders. At present, the premium in Malaysia includes only two factors which are the sum insured and the cubic capacity of the engine.
