Fuzzy control of multiple medium admissions in ATM networks

In the ATM network, there are many media, and every kind of medium has a lot of parameters, which need to be satisfied for conditions of this medium admission in order to enter upon the ATM network. In other words, if the medium of a customer can be admitted into an ATM network, its parameters must meet all permissible requirements, namely "satisfied conditions", and "accord with the demands for admission ",..., and so on. These concepts are all fuzzy. At the same time, how can they get the shortest path? How can the most media are passed in the shortest time, to be handling in uncertain status? We handle these problems by using the fuzzy reasoning of the expert system, and methods of the picture theories
