Create Vulnerability Map from 3 Maps

E ceil combine three map

: this equation will combine NO3, TDS, & T

A=table('no3', class(no3), 'fuzz');

B=table('tds', class(tds), 'fuzz');

C=table('tritium', class(tritium), 'fuzz');

: value of gamma?

gam=0.95;

fprod=A*B*C;

fsum=1.-((1-A)*(1-B)*(1-c));

fgam=pow(fsum,gam)*pow(fprod,1-gam);

result(fgam)
