DryIce, Inc., is a manufacturer of air conditioners. The company anticipates nationwide demand for the next year to be 180,000 units in the South, 120,000 units in the Midwest, 110,000 units in the East, and 100,000 units in the West. Managers at DryIce are designing the manufacturing network and have selected four potential sites --- New York, Atlanta, Chicago and San Diego. Plants could have a capacity of 200,000 units. The annual fixed costs at the four locations are shown in the following table, along with the cost of producing and shipping an air conditioner to each of the four markets. Where should Dryice build its factories and what will be the quantities to be produced at each location and shipped to each market? How does the solution change if you are required to locate a plant in each location? Comment on the solution

Answer #1

The Vogel's Approximation Method or VAM is an iterative procedure calculated to find out the initial feasible solution of the transportation problem.

Our initial matrix we have

East South Mid West West Plant max capacity Fixed Cost
New York 211 232 240 300 2,00,000 6000000
Atlanta 232 212 230 280 2,00,000 5500000
Chigago 238 230 215 270 2,00,000 5600000
San Diego 299 280 270 225 2,00,000 6100000
Total Demand 110000 180000 120000 100000

We follow the follwoing steps to find our first solution

East South Mid West West Plant max capacity Iteration 1 Fixed Cost
New York 211 232 240 300 2,00,000 21 6000000

San Diego 299 280 270 225 2,00,000 45 6100000
Total Demand 110000 180000 120000 100000

As complete demand of colmun "West " is fulfilled so we remove it

East South Mid West Plant max capacity Iteration 2 Fixed Cost
New York 211 232 240 2,00,000 21 6000000
Atlanta 232 212 230 2,00,000 20 5500000
Chigago 238 230 215 2,00,000 15 5600000
San Diego 299 280 270 1,00,000 10 6100000
Total Demand 110000 180000 120000
Iteration 2 21 20 15

We make allocation to new york at EAST

South Mid West Plant max capacity Iteration 3 Fixed Cost
New York 232 240 90,000 8 6000000
Atlanta 212 230 2,00,000 18 5500000
Chigago 230 215 2,00,000 15 5600000
San Diego 280 270 1,00,000 10 6100000
Total Demand 180000 120000
Iteration 3 20 15

Making allocation at Atlanta Chicago

In last allocation we allocate to Chicago Middle west

We can summarise our allocation as

The above table shows most optimised way in which we can do allocations.

Where should Dryice build its factories and what will be the quantities to be produced at each location and shipped to each market?

We can evaluate the cost beared at each location to answer question

Place Fixed cost Variable cost Total cost (10^4)
New York 6000000 211*110000+232*90000 5009
Atlanta 5500000 212*180000+230*20000 4776
Chigago 5600000 215*120000+230*80000 4980
San Diego 6100000 225*100000+270*100000 5560

So we can conclude he should make his plant at ATLANTA. He will be shipping to south and middle west if he is working his plant with maximum capacity. In case he want to keep his cost to minimum he should only ship to south.

In case he is interested to make plant in every location, the respective plant capacity is given in table below
