    This brief video explains the components of LP Sensitivity Analysis using an Excel Solver Report.

    A few questions were also answered based on the following Linear Programming model.

    Max 50A + 60B + 55C
    s.t.
    A + B + C ≤ 100
    2A + 3B + 2C ≤ 300
    2A + 3B + 2C ≥ 250
    A + 2C ≥ 60
    1.

    State the optimal solution
    2.

    What is the optimal objective function value?
    3.

    What would happen to the optimal solution if
    a) the unit profit on B decreases by 20?
    b) the unit profit on C decreases to 45?
    c) the unit profits on A & C change to 53 (Simultaneous Changes-100% Rule)?
    4.

    Interpret the reduced cost for A
    5.

    What would happen to the objective function if
    a) the RHS of constraint 1 increases by 5?
    b) the RHS of constraint 2 decreases to 250?
    c) the RHS of constraint 4 changes to 44?
    6.

    Which constraints are binding?
    7.

    What are the slack/surplus values?
