MODEL:
! Acceptance sampling design. From a large lot,
take a sample of size N, accept if C or less are
defective;
! Poisson approximation to number defective is used;
DATA:
AQL = .03; ! "Good" lot fraction defective;
LTFD = .08; ! "Bad" lot fraction defective;
PRDRISK = .09; ! Tolerance for rejecting good lot;
CONRISK = .05; ! Tolerance for accepting bad lot;
MINSMP = 125; ! Lower bound on sample size to
help solver;
ENDDATA
[OBJ] MIN = N;
! Tolerance for rejecting a good lot;
1  @PPS( N * AQL, C) <= PRDRISK;
! Tolerance for accepting a bad lot;
@PPS( N * LTFD, C) <= CONRISK;
! Give solver some help in getting into range;
N >= MINSMP; C>1;
! Make variables general integer;
@GIN( N); @GIN( C);
