COB 291 Test 2
change in coefficient of the objective function WITHIN the allowable range
-optimal solution WILL NOT change -optimal objective function value WILL change
change in RHS of a constraint WITHIN allowable range and NONBINDING
-optimal solution WILL NOT change -shadow price is zero -OFV will not change
change in coefficient of the obj func BEYOND the allowable range
-optimal solution WILL change -optimal obj func val WILL change
change in RHS of a constrain BEYOND allowable range
-optimal solution WILL change, but cannot be calculated -pattern of change in the obj func val can be predicted
relaxing a constraint
OFV will be improved or not changed
tightening a constraint
OFV will worsen or not change
