Intro to Mgmt. Science Cases Chapter 2Chapter 2An Introduction to Linear ProgrammingCase Problem 1: Workload Balancing1.Production Rate(minutes per printer)ModelLine 1Line 2Profit Contribution (\$)DI-9103442DI-9506287Capacity: 8 hours60 minutes/hour = 480 minutes per dayLet D1 = number of units of the DI-910 producedD2 = number of units of the DI-950 producedMax42D1+87D2s.t.3D1+6D2480Line 1 Capacity4D1+2D2480Line 2 CapacityD1, D2 0The optimal solution is D1 = 0, D2 = 80. The value of the optimal solution is \$6960.Management would not implement this solution because no units of the DI-910 would be produced.2.Adding the constraint D1 D2 and resolving the linear program results in the optimal solution D1 = 53.333, D2 = 53.333. The value of the optimal solution is \$6880.3.Time spent on Line 1: 3(53.333) + 6(53.333) = 480 minutesTime spent on Line 2: 4(53.333) + 2(53.333) = 320 minutesThus, the solution does not balance the total time spent on Line 1 and the total time spent on Line 2. This might be a concern to management if no other work assignments were available for the employees on Line 2.4.Let T1 = total time spent on Line 1T2 = total time spent on Line 2Whatever the value of T2 is, T1 T2 + 30T1 T2 - 30Thus, with T1 = 3D1 + 6D2 and T2 = 4D1 + 2D23D1 + 6D2 4D1 + 2D2 + 303D1 + 6D2 4D1 + 2D2 30Hence,
