The application of virtual maintenance technology can find the problems in products maintainability design as early as possible, assuring the qualities and reducing the life-cycle cost. So it is very important for the design of complicated equipments such as aircraft. Aimed at the requests of aircraft maintainability design, this paper compared two kinds of virtual maintenance modes, non-immersive...
Electronic money products have advanced quickly with the rapid growth of electronic commerce, and different stakeholders show shared concern on the related impact. In order to have a holistic and in-depth analysis of the e-money issues, this paper studies the e-money dynamics from complex system perspective. System complexity analysis is conducted and a four-phase modeling approach is proposed. This...
In e-commerce environments, problems of credit risks are more serious than that of the traditional commerce due to interactions between unfamiliar peers. The application of credit evaluation system for e-commerce plays a important role in mitigating credit risks. This paper proposes an improved AHP-based multi-dimension credit evaluation model based on an analysis of the drawbacks of the current model,...
The cooperative control of both electrode remelting rate and position was applied in order to obtain optimal electroslag remelting metallurgy effect and improve melting production efficiency. The electroslag remelting process model was analyzed. Cooperative controller parameters were optimized by improved genetic algorithm based on ITAE criterion. The dynamic performance was analyzed to electroslag...
A model is a blueprint of a system, which influences the quality of the system. A high quality model should specify not only the functional attributes of a system, i.e., what the system can do, but also the non-functional attributes, i.e., how well the system can do. Modeling for non-functional attributes, especially, the integration of nonfunctional attributes description with functional description...
Perceived predominant melody of music is the most convenient and memorable description and can be used for content-based music retrieval. However, including human voice and multiple musical instruments playing together, it is difficult to extract a predominant contour of pitches directly from MP3 music recordings. In order to build a similarity music melody model, several audio files, whose melody...
