Analytic hierarchy process (AHP) is a frequently used method for ranking alternatives. The alternatives to be ranked are modeled based on a set of criteria. The ranking computed by AHP is trusted on faith notwithstanding the fact that a model is an approximation and liable to failure. We present a model to estimate the trust in the AHP ranking. The model helps in determining if it is prudent to...

Trains of action potentials in CA1 pyramidal neurons are followed by a prolonged calcium-dependent postburst afterhyperpolarization (AHP) that serves to limit further firing to a sustained depolarizing input. A reduction in the AHP accompanies acquisition of several types of learning and increases in the AHP are correlated with age-related cognitive impairment. The AHP develops primarily as the...

ارتقای وضع موجود در هر فعالیتی مستلزم شناسایی عوامل مؤثر بر بهبود، اولویت‏بندی آن عوامل و اقدام متناسب با آن است. در این تحقیق، مدلی مبتنی بر تلفیق ارزیابی وضع موجود با AHP گروهی- فازی معرفی شده است. براساس این مدل، از ارزیابی وضع موجود، شکاف عملکردی و از AHP گروهی- فازی وزن عوامل تعیین شده و نتایج حاصل برای تعیین اولویت نهایی بهبود و دستیابی به شرایط مطلوب، مورد استفاده قرار گرفته است. در تحقی...

Anosognosia for hemiplegia (AHP) is a lack of awareness about paralysis following stroke. Recent explanations use a 'forward model' of movement to suggest that AHP patients fail to register discrepancies between internally- and externally-generated sensory information. We predicted that this failure would impair the ability to recall from memory whether information is internally- or externally-...

Previous research indicates that an age-related increase in the amplitude of the Ca2+-dependent, K+-mediated afterhyperpolarization (AHP) is related to cognitive decline. However, because the AHP is measured following completion of training, it is unclear whether the AHP amplitude is strictly dependent on biological aging or is modified by the training procedure. To address this distinction we ...

The Analytic Hierarchy Process (AHP) proposed by T. L. Saaty has been widely used in decision making. Inner dependence method AHP is used for cases in which criteria or alternatives are not independent enough and using the original AHP or inner dependence AHP may cause results to lose reliability because the comparison matrix is not necessarily sufficiently consistent. In such cases, fuzzy repr...

Anosognosia for hemiplegia (AHP) is relatively common among patients who suffer from a stroke. It is characterized as a denial of bodily paralysis and the complexity of studying it is evident. Anosognosia is a neuropsychological deficit of self-awareness and most frequently associated with both cortical and subcortical lesions distributed within the right hemisphere, resulting in a left hemiple...

Analytic Hierarchy Process (AHP) is major method for decision making, and inner dependence AHP is used for cases in which criteria or/and alternatives are not independent enough. Using the original AHP or inner dependence AHP may cause results that cannot have enough reliability because of the inconsistency of the comparison matrix. In such cases, fuzzy representation for weighting criteria or/...

This paper concerns with proposing a fuzzy logic based expert system to breakthrough the problem of alternatives evaluation in Analytic Hierarchy Process (AHP). AHP as a multi criteria decision aid helped decision makers for analyzing and prioritizing the alternatives in a hierarchical structure. During times AHP encountered some problems. Hence, fuzzy analytic hierarchy process (FAHP) and some...
