Exhibit 7.4
The following questions are based on the problem below.
Robert Gardner runs a small,local-only delivery service.His fleet consists of three smaller panel trucks.He recently accepted a contract to deliver 12 shipping boxes of goods for delivery to 12 different customers.The box weights are: 210,160,320,90,110,70,410,260,170,240,80 and 180 for boxes 1 through 12,respectively.Since each truck differs each truck has different load capacities as given below:
Robert would like each truck equally loaded,both in terms of number of boxes and in terms of total weight,while minimizing his shipping costs.Assume a cost of $50 per item for trucks carrying extra boxes and $0.10 per pound cost for trucks carrying less weight.
The following integer goal programming formulation applies to his problem.
Y1 = weight loaded in truck 1;Y2 = weight loaded in truck 2;Y3 = weight loaded intruck3;Xi,j = 0 if truck i not loaded with box j;1 if truck i loaded with box j.
Given the following spreadsheet solution of this integer goal programming formulation,answer the following questions.
-Refer to Exhibit 7.4.The spreadsheet model has scaled all the weights from pounds into 100s pounds.How does this scaling effect the solution obtained using the Risk Solver Platform RSP)?
