**Algorithm 3.1 Partition method for LCC.**


*fij*=1- (*x1*| *ri1* – *rj1*|+*x2*| *ri2* – *rj2*|+*x3*| *ri*3 – *rj3*|+*x4*| *ri4* – *rj4*|),when *i*≠*j*, and 0< <1, and *x1*+ *x2*+ *x3*+ *x4*=1, *xk*>0 (1≤*k*≤4);

3. build the fuzzy equivalence matrix;

Repeat do

*FT*=*FM* ⊙ *FM*; //⊙ is the operation theorem to take the maximum and minimum

If *FT*=*FM* then goto (4);

FM=FT;

End do;
