Next-generation grid systems where the emphasis shifts to distributed global collaboration, a service-oriented approach, and information layer issues exhibit a strong sense of automation. Requirements for these systems resemble the self-organizing and the self-healing properties of natural ecosystems. Inspired by this resemblance, we introduce some key(More)
In the first part of this paper, we investigate explicit structure of the typical Takagi– Sugeno (TS) fuzzy PI and PD controllers. By typical, we mean the use of at least three trapezoidal or triangular input fuzzy sets for each input variable, fuzzy rules with linear consequent, Zadeh fuzzy logic AND operator and the centroid defuzzifier. This(More)
Recent studies have shown that both Mamdani-type and Takagi-Sugeno-type fuzzy systems are universal approximators in that they can uniformly approximate continuous functions defined on compact domains with arbitrarily high approximation accuracy. In this paper, we investigate necessary conditions for general multiple-input single-output (MISO) Mamdani fuzzy(More)
Grid technologies facilitate innovative applications among dynamic virtual organizations, while the ability to deploy, manage, and properly remain functioning via traditional approaches has been exceeded by the complexity of the next generation of grid systems. An important method for addressing this challenge may require nature-inspired computing(More)
—Network services in the future Internet are required to be highly available, ubiquitous, self-managing, and adaptable to dynamic environments. A promising way to implement such network services is combining mobile agent approaches with ecosystem-inspired evolutionary approaches. However, this perspective is still far from being practically implemented. An(More)
