    In cell CE, I wrote 150 on board and should have been 50 (200-150 = 50). The calculation for ZQ is correct.
    From To Cost Qty Sub Total
    A D 6 150 900
    A F 9 50 450
    B E 7 200 1400
    C F 12 150 1800
    C E 10 50 500
    Total 5050
    Taking a guess at your sequence you numbers are cells AD + CF + BE + CE + AF. I agree with cells AD, CF, and AF. Cell BE has a cost of $7 per unit and CE has a cost of $10 per unit and not $12.
    Thank you very much. I enjoy the intellectual exchange.

    I believe there are some errors. CORRECT ME IF I AM WRONG
    Once you have calculated all the U and V, and you analyze that you should add more units in C-F (since = -1) . THEN IN C-E you need to ad 50 and NOT 150.
    THIS AFFECTS THE FINAL MODI COST = 150x6 + 150x12 + 200x12 +50x12 +50x9 = 6050,
    Therefore the TOTAL SAVINGS ARE 6050-5450= 600 $

    Yes, It appears I wrote the number incorrectly on the board but used the correct number (50 and 150) in calculating ZQ. I will correct in the coming weeks. Thank you. I cracked under pressure! LOL.

    Is U1 always equal to zero? Or only if there is no most occupied cell?

    • @EdDansereau
      @EdDansereau  5 років тому

      Yes, U1 is always equal to zero. Think of it as starting at the origin (0,0).

    I do not understand when the evaluation. why the capacity exceeds the limit?

    • @EdDansereau
      @EdDansereau  7 років тому

      Hi, I am not sure I understand your question. My definition of capacity is the limits of supply (how much is in stock at each warehouse) and demand (how much each customer wants). In this basic example we make the assumption that capacity may not exceed the limit. Please tell me more and I will attempt to help you out.

      In minutes to 7.03. When you explain. I see that the value on CF + CE if summed is not 200. and BE + CE is not 250. is it okay? I have not understood . please help to explain to me

    At the 7 minute mark we have determine that cell CF is the entering cell for the improve solution and that BF is the leaving cell. We also need to respect the integrity of the demand for column F (200 units) and column G (250 units) as well as the supply for row B and row C. To do this we form what I call a "box". Think of it as - BF + CF - CG + BG. Since we take away 150 units from BF we must add 150 units to BG to maintain the integrity of the supply for row B. But that increases the demand in row so we must subtract 150 units from CG. Then we need to add 150 units to CF. This addition and subtract of cells in the box satisfy supply and demand. Same as in the stepping stone method, Maybe my Stepping Stone video will give you the answers you need. ua-cam.com/video/RGKQXBL2YWo/v-deo.html
