Multiply two fuzzy numbers -

-

can please give me step step procedure on how multiply 2 fuzzy numbers , b where

        {(x+1)/2     |(-1<x<=1), ua(x) = {(3-x)/2     |(1<x<=3),         {0           |otherwise          {(x-1)/2     |(1<x<=3), ub(x) = {(5-x)/2     |(3<x<=5),         {0           |otherwise

multiplication bit tricky, if have simple triangular membership functions. there step-by-step description here: http://debian.fmi.uni-sofia.bg/~cathy/softcpu/fuzzy_book/chap5-3.pdf

in cases, however, simpler approximation described in example 5.12 (p 8) enough. in multiply each of 3 mf-numbers in 1 set 3 corresponding numbers in other. (the results are, however, not intuitive numbers close 0 - care comment on/explain this?)
