Sensitivity Analysis
Objective function: 2. The allowable increase/decrease associated with the original coefficient of a decision variable tells us the range in which the coefficient of a given decision variable in the objective function may be increased/decreased without changing the optimal solution, where all other data are fixed. Constraint: 2. The above interpretation of shadow price is valid only within a
range of the given RHS. The shadow price may change to a different value
outside this allowable range. The shadow price information does not tell us how
the optimal solution mix (i.e., the values for decision variables X1,
X2, etc.) changes. |
