Environmental risk modelling under probability-normal interval-valued fuzzy number
Tsinghua University Press - Tập 5 - Trang 359-371 - 2013
In almost all the realistic circumstances, such as health risk assessment and uncertainty analysis of atmospheric dispersion, it is very essential to include all the information into modelling. The parameters associated to a particular model may include different kind of variability, imprecision and uncertainty. More often, it is seen that available informations are interpreted in probabilistic se...... hiện toàn bộ
Credibilistic value and average value at risk in fuzzy risk analysis
Tsinghua University Press - Tập 3 - Trang 69-79 - 2011
Decision making in real world is usually made in fuzzy environment and subject to fuzzy risks. The value at risk (VaR) is a widely used tool in risk management and the average value at risk (AVaR) is a risk measure which is a superior alternative to VaR. In this paper, we present a methodology for fuzzy risk analysis based on credibility theory. First, we present the new concepts of the credibilis...... hiện toàn bộ

Fuzzy transitivity and monotonicity of cardinality-based similarity measures
Tsinghua University Press - Tập 4 - Trang 145-153 - 2012
The interrelationship of notions is presented in fuzzy transitivity and monotonicity of fuzzy similarity measures. It is observed that the axiom of fuzzy transitivity may replace that of monotonicity in the definition of fuzzy similarity measures.

Some single-machine scheduling problems with actual time and position dependent learning effects
Tsinghua University Press - Tập 1 - Trang 161-177 - 2009
In this paper we study some single-machine scheduling problems with learning effects where the actual processing time of a job serves as a function of the total actual processing times of the jobs already processed and of its scheduled position. We show by examples that the optimal schedules for the classical version of problems are not optimal under this actual time and position dependent learnin...... hiện toàn bộ
Flocking of mobile intelligent agents on fuzzy system with optimal theories
Tsinghua University Press - Tập 2 - Trang 347-359 - 2010
A dynamical model is presented for autonomous mobile intelligent agents. Based on the local information of the swarm, a fuzzy logical controller (FLC) is built for the attraction/repulsion function. The flocking of the separation, cohesion and alignment are achieved by combining with the rate consensus algorithm. Based on the optimal controller theories, a performance target is used to measure the...... hiện toàn bộ
Application of system NCF method to ice flood prediction of the Yellow River
Tsinghua University Press - Tập 1 - Trang 191-204 - 2009
Combined forecasts is a well-established procedure for improving forecasting accuracy which takes advantage of the availability of both multiple information and computing resources for data-intensive forecasting. Therefore, based on the combination of engineering fuzzy set theory and artificial neural network theory as well as genetic algorithms and combined forecast theory, the system Non-linear ...... hiện toàn bộ
