In order to find the satisfactory solution of the multi-objective fuzzy optimization problem of structures , the membership functions are constructed for the subsets of the fuzzy objectives subject to the fuzzy constraints and three approaches are then presented by using the different types of generalized fuzzy decision-making.

The fuzzy control model, fuzzy control rules, fuzzy inference and fuzzy adjudication are developed.

Grouping fuzzy decision based on simplified fuzzy classification association rules;

A realtime visual surveillance method is presented,which is based on exception recognition and fuzzy decision.

Based on this application methods of Fuzzy Decision and Arithmetic Average Filtering are presented, this topic has special important significance on saving the I/O ports and simplifying the circuit design.

Image edge connection based on fuzzy logic;

The algorithm of multi-level generalized fuzzy comprehensive estimation is studied to satisfy various users in college by using the system structure combining C/S with B/S and other advanced computer technology.
