The　fuzzy　linear-weight　transformation　simplex　method　is　designed　for　multi-feature　optimization.　The　mathematical　principle　is　described.　The　fuzzy　relation　matrix　is　developed　on　the　basis　of　membership　functions,　which　are　expressed　here　as　a　set　of　linear　equations.　The　features　to　be　optimized　are　weighted　according　to　the　needs　of　the　user.　The　Basic　program　is　operated　on　an　Apple-II　or　compatible　computer.　The　method　is　applied　to　select　the　optimum　reaction　conditions　for　the　1,10-phenanthroline/H2O2/CTMAB/Cu2+　chemiluminescence　system.　©　1990.
