Study Notes
Northwest Corner Method
- The method starts at the top-left corner of the cost matrix, where the first supply and demand meet.
- The first step involves allocating as much supply as possible to the top-left cell while considering the supply and demand constraints.
- If a row or column reaches zero supply or demand, that row or column is crossed out of consideration for further allocations.
- In the case where only one row or column remains not crossed out, it must be fully allocated to fulfill the remaining supply or demand.
Total Cost Calculation
- Total cost can be calculated by multiplying the unit costs of the routes ($200, $50, $175, $125, $150, $250) by their respective allocations and summing these values.
Unbalanced Transportation Problems
- An unbalanced transportation problem occurs when total supply does not equal total demand, requiring adjustments such as adding dummy sources or destinations to balance.
Additional Considerations
- Data for transportation problems may require adjustments, such as balancing supply and demand or ensuring all routes are feasible.
