The following table shows the sensitivity analysis for a LP problem.

1. What is the objective function value?

2. How much Material used by the optimal solution ?

3. How much Time used in Department 1?

4. If the Increase in the objective coefficient of Product 1 is 5 units then what happens for the

Optimal solution? How about objective function value?

5. If the objective coefficient of Product 4 is decreased by 5 units then what happened for optimal solution?

6. If there are Simultaneous changes in objective coefficients of Product 2 and Product 3

such that the coefficients of product 2 increases by 2 units and coefficients of product 3 decreases by 7 units then what happened for optimal solution?

7. If RHS value of the constraint Time in Department 2 decreases by 20 units then what happens for optimal solution?

8. If we add a new constraint: P₁ + P₂ 200 to LP, what happens for optimal solution?
