This section is then Part composite operator, the main factors continue to be described projection type (product of the maximum) and take a small upper and two synthetic type operator.
1. The main factors highlight type (product of the maximum)
Definition: 
the product of the largest operators not only highlights the main factors, but also taking into account other factors. When the main factors that determine the type (whichever is greater operator to take small) indistinguishable, the model can be used.
Procedures are as follows:
r1=[0.1 0.4 0.3 0.1 0.1
0.2 0.5 0.2 0.1 0
0.2 0.4 0.3 0.1 0]
r2=[0.1 0.3 0.2 0.1 0.3
0.1 0.3 0.3 0.2 0.1
