Question
- The Calcio Coal Company produces coal at four mines and ships it to four power plants (P1-P4). The cost per ton of producing coal and the production capacity (in tons) for each mine are known. The number of tons of coal demanded by each customer is also known. The cost (in dollars) of shipping a ton of coal from a mine to each plant is available as well. The following table provides the data:
Mine | P1 | P2 | P3 | P4 | Capacity | Cost |
1 | 9 | 15 | 8 | 10 | 125 | 50 |
2 | 7 | 15 | 14 | 12 | 100 | 57 |
3 | 5 | 5 | 11 | 12 | 150 | 55 |
4 | 3 | 6 | 8 | 11 | 120 | 61 |
Demand | 110 | 115 | 135 | 130 |
