Paul Bergey is in charge of loading cargo ships for International Cargo Company (ICC) at the port in Newport News, Virginia. Paul is preparing a loading plan for an ICC freighter destined for Ghana. An agricultural commodities dealer wants to transport the following products aboard this ship. Commodity A B C D Amount Available (tons) 4,800 2,500 1,200 1,700 Volume per Ton (cubic feet) 40 25 60 55 Profit per Ton ($) 70 50 60 80 Paul can elect to load any and/or all of the available commodities. However, the ship has three cargo holds with the following capacity restrictions. Cargo Hold Forward Center Read Weight Capacity (tons) 3,000 6,000 4,000 Volume Capacity (cubic feet) 145,000 180,000 155,000 More than one type of commodity can be placed in the same cargo hold. However, because of balance considerations, the weight in the forward cargo hold must be within 10% of the weight in the rear cargo hold, and the center cargo hold must be between 40% and 60% of the total weight on board. 1. Formulate the LP model for this problem. 2. Create the spreadsheet model and use Solver to solve the problem. Please use excell!!!

Paul can elect to load any and/or all of the available commodities. However, the ship has three cargo holds with the following capacity restrictions.
Cargo Hold
Forward Center Read
Weight Capacity (tons) 3,000 6,000 4,000
Volume Capacity (cubic feet) 145,000 180,000 155,000
More than one type of commodity can be placed in the same cargo hold. However, because of balance considerations, the weight in the forward cargo hold must be within 10% of the weight in the rear cargo hold, and the center cargo hold must be between 40% and 60% of the total weight on board.
