    My model on my solver proved infeasible for your second solution when demand exceed supply. I used greater than or equal sign for the demand constraints and less than and equal sign for the supply constraints, then I got an optimal solution.

    2. Do you also have videos for solving Linear Programming problems using Simplex approach?
    Again, thank you for the tutorials.

    Fantastic videos Joshua. Thank you.
    Question: what if demand and supply are always equal (e.g., a package delivery network where all packages must get to their destinations), how might we minimize the cost of collecting the packages from (n) distribution centers and delivering them to (n) cross dock facilities. For bonus points, we have 3 different vehicle sizes (S, M, L) with different operating costs. The DCs have different quantities of packages to deliver to each cross-dock. As a result S sized vehicle may get full before the end of it's run and it may have been more efficient to send a M or L sized vehicle, etc.
    I'd love your perspective (or anyone here) on how to solve this riddle.
    Thank you in advance and keep the great videos coming.

    Thanks for the great video! How could I use this concept when the cost for each route(eg. 5,6,4,6,3,7 in your video) depends on the amount of item (xij)? I am wondering if the linear programming can be applied for the case where fundamental input data(cost in this case) is subject to change.

    • @joshemman
      @joshemman  Год назад

      Unfortunately, no. The prices in an LP transportation problem must be fixed irrespective of volume.
      If the prices change with volume, it will no longer be a linear program.

    • @joshemman
      @joshemman  Год назад

      @@강인수-t9n Non-linear programs (NLPs) are similar to linear programs in that they both contain algebraic functions and inequalities. The only difference is that linear programs contain only linear expressions such that if X and Y are decision variables, then XY or X^2 are invalid. In your case, if X = quantity and Y = Price, then total price XY is nonlinear. You can then solve it in Excel’s Solver by using the GRG Nonlinear method.
