Supply chain is a complicated, open system, for the constant development, and fierce degree of market competition of the society increase day by day, the discrimination and management of risk of Supply chain are more essential. Kinds of risk factors of Supply chain are analyzed in the text, according to the influence degree of each risk factor, a method combined BP neural network and fuzzy evaluation...
On the basis of studying the working principle of discrete fuzzy control, according to the structural characteristic and the ability of RBF neural network approaching to any unknown function, the clustering and nonlinear mapping function of RBF neural network are used to implement discrete fuzzy inference and control. If only a RBF neural network is suitably designed and well trained by a discrete...
In this paper, based on the Lebesgue measure of level cutsets and the membership degree of an element in level cut-sets, we introduce the concept of level creditability of fuzzy numbers, present a necessary and sufficient condition of level creditability being equal to 1 for each ?? ?? [0,1], and then consider the basic properties (such as continuity, monotonicity etc.) of level creditability and...
