The execution of an agent's complex activities, comprising sequences of simpler actions, sometimes leads to the clash of conflicting functions that must be optimized. These functions represent satisfaction, short-term as well as long-term objectives, costs and individual preferences. The way that these functions are weighted is usually unknown even to the decision maker. But if we were able to understand...
In order to analyze the fuzzy and low signal-noise ratio on fault characteristics of hydraulic pump, a new rough set (RS) fault diagnosis algorithm based on principal component analysis (PCA) as guide is proposed. Firstly, the algorithm uses wavelet analysis to process noise abatement so as to extract the effective fault characteristic. Secondly, it utilizes PCA method to make dimension reduction...
