For general type-2 fuzzy sets, the defuzzification process is very complex, and the exhaustive direct method of implementing type-reduction is computationally expensive and turns out to be impractical. This has inevitably hindered the development of type-2 fuzzy inferencing systems in real world applications. The present situation will not be expected to change, unless an efficient and fast met...

The wireless industry is rapidly transitioning from proprietary architecture to more flexible, cost effective open wireless architecture (OWA) systems. This transition is creating interesting challenges for developers, manufacturers, integrators, operators and end-users as they wrestle with complexities of open wireless systems. Fourth Generation (4G) Mobile Communications should not focus only...

The ordered weighted averaging (OWA) operator and its associated weight vectors have been both theoretically practically verified to be powerful effective in modeling the optimism/pessimism preference of decision makers. When several different OWA are offered, it is necessary develop certain techniques aggregate them into one vector. This study firstly details motivating examples show necessity...

The construction of functions that simultaneously generalize weighted means and OWA operators is an interesting topic has received special attention in recent years. Due to the properties they satisfy, one most generalization are SUOWA operators, which have been widely studied literature. In a paper, new introduced, Semi-SUOWA close relationship with operators. main aim this paper analyze games...

We develop a new approach that uses the ordered weighted averaging (OWA) operator in the selection of financial products. In doing so, we introduce the ordered weighted averaging distance (OWAD) operator and the ordered weighted averaging adequacy coefficient (OWAAC) operator. These aggregation operators are very useful for decision-making problems because they establish a comparison between an...

Neurofibromatosis type-1 (NF-1) associated-intrathoracic meningocele is a rare clinical finding. We report the cases of two adults who were diagnosed with NF-1-associated intrathoracic meningoceles and successfully treated with a novel surgical technique called “dural turnover repair method.” Both patients were symptomatic. Preoperative imaging showed a cystic lesion in the thoracic cavity of b...

We describe the problem of decision making under ignorance and discuss the need of introducing a decision attitude or disposition in solving this problem. We show the OWA operators provide a general framework for evaluating the alternatives when the payoffs are numeric values. We then turn to the problem of decision making when the payoffs are linguistic values drawn from an ordinal scale. A so...
