Transportation MODI method شرح

** Course: Operations Research/ Quantitative Analysis Methods

** Key Words:
- MODI Method to Improve Transportation Solution.
- Steps to reach optimal solution for transportation problem:
Step 1. Find initial feasible solution (starting feasible solution)
--North West Corner Method.
   • Transportation North West Corner Meth...  
- Minimum Cell Cost Method.
   • Transportation Minimum Cell Cost Meth...  
- Vogel Approximation Method.
   • Transportation Vogel Approximation Me...  

Step 2. Check optimality of the solution by finding improvement indices for each empty cell (unused cell)
- Stepping Stone Method.
- MODI method.

Step 3. If the solution is optimal stop; otherwise improve the solution and get “improved solution”.
- Stepping Stone Method.

Step 4. Repeat step 2 and step 3 until reach the optimal solution.
