![]() After selecting OK the Spreadsheet form will appear on the screenġ. For the example problem, the completed parameters will appear as follows 3. Under the File drop-down menu, select “new problem” and this dialog box will appear 2. From the WinQSB software set select “ Linear and Integer Programming ” 1 2 3 4 5 6 50 60 40 35 25 2 4 5 8 9 From the transshipment node: 1 unit of output requires 2 units of inputġ. Now you are ready to move to the software. All constraints must have variables on the left side and a constant on the right. Using WinQSB to solve Linear Programming Models Assume we wish to solve the transship problem depicted in the following network diagram Minimize Z= 2x14 + 4x24 + 5x34 + 8x45 + 9x46 Subject To: x14 <= 50 x24 <= 60 x34 <= 40 x45 = 35 x46 = 25 x14 + x24 + x34 – 2x45 – 2x46 = 0 First, formulate the model in standard LP form.
