In order to overcome the drawbacks of AHP in solving complex decision-making problems, ANP is applied in the evaluation of enterprise technology innovation ability. Due to Interval type-2 fuzzy sets can handle uncertainty of linguistic variables in a more flexible and precisely way than Type-1 fuzzy sets with their fuzzy membership functions, a fuzzy ANP method with interval type-2 fuzzy sets is proposed...
The linguistic weighted average (LWA) of interval type-2 fuzzy sets is an extension of the fuzzy weighted average (FWA) of type-1 fuzzy sets. Currently, the commonly used methods of both FWA and LWA are based on a-cuts decomposition of the type-1 of type-2 fuzzy sets, which involves large amount of calculations, and the result is not accurate. In this paper, we propose a new algorithm to obtain the...
The fault detection and analysis for power transformer are the key measures to improve the security of power systems and the reliability of power supply. Due to the complicity of the power transformer structure and the variations in operating conditions, the occurrence of a fault inside power transformer is uncertain and random. Until now, the fault statistics of power transformer is very limited...
Being one of the most important equipments for power transmission, the fault diagnosis and analysis of power transformer is the key to the security and reliability of power supplies. It leads to uncertainties and randomicity for the fault happening that the complicated structures of power transformers and its operating environment, and it is hard to accumulate the statistical information of fault...
