Model-based control design is essential in the control of solar power plants. Dynamic linguistic equation (LE) models operate accurately in most operating conditions. Smooth transitions between submodels are based on fuzzy logic and fuzzy set systems are also used for special situations. The hybrid simulator has been tested with extensive process data, and the adaptive controller tuned with the...

many of the so-called organizational strategies on which companies are dependent, are not endurable. these strategies may not be well structured and cannot stand the test of time. thus, making the right decision is extremely important for strategic planning. the proposed strategy formulation framework in this paper (fuzzy bsq) is a powerful management tool in strategic planning that integrates ...

To apply fuzzy logic, two major tasks need to be performed: the derivation of production rules and the determination of membership functions. These tasks are often difficult and time consuming. This paper presents an algorithmic method for generating membership functions and fuzzy production rules; the method includes an entropy minimization for screening analog values. Membership functions are...

in recent years, agriculture has become the prime polluter of natural resources. it is therefore essential to make assessments based on reliable indicators to ensure that an agricultural system remains not only productive, but also ecologically sound. a large area of arable land in guilan province is devoted to rice cultivation so the transition to environmentally sound agricultural practice in...

Fuzzy analytic hierarchy process (AHP) has been widely used for a variety of applications such as supplier selection, customer requirements assessment and the like. The vast majority of the applications, however, were found avoiding the use of sophisticated approaches for fuzzy AHP such as fuzzy least squares method while using a simple extent analysis for the sake of simplicity. The extent ana...

Every passenger who travels by air is exposed to security screening. As part of this procedure, the passenger typically is screened by a walk-through metal detector. Such a device should effectively detect prohibited metal items while simultaneously ensuring adequate throughput at the security screening checkpoint. Therefore, it is necessary to evaluate both these factors when selecting an appr...

In this article, joint medical and data analysis expertise is brought to bear using fuzzy knowledge representation and 'intelligent' aggregation techniques to solve a difficult medical diagnosis problem, that of sleep apnea syndrome screening.
