(4) For the example of equipment selection model in chapter 7, modify the following highlighted parameters and formulate a mathematical model similar to one given in slide 44. The marketing department has demand forecast figures which have been aggregated for the four pseudo models. It has been determined that 2000, 1500, 1800 and 1000 units of the basic, high-tech, sports and luxury models will be demanded during the next six months. The models require one or more of three operations, referred to as 01, 02, and 03, each in quantity of 200, 200 and 150. Three machine types and two material handling systems available for performing the three operations and transporting the models. These are denoted as Mi, M. Ms and MHI, MH2, respectively. The time capacity of each production machine and handling device is 400 and 350 hours, respectively. The cost of machines Mi, M, and Ms are $230,000; $250.000; $310,000 The cost of material handling carriers MH., MH2 are $90,000 and $130,000 The available budget is $10,000,000. the cost of performing operation 0; on production equipment type M; The cost of handling part type P, using material handling system type MH;, Operation and transportations times LP Model for example MIN 90000 NMH1 + 130000 NMH2 + 230000 NM1 + 250000 NM2 + 310000 NM3 + 6 X11 + 12 X12 + 8 X13 + 4 X21 + 5 X22 + 4 X23 + 12 X31 +5 X32 +5 X33 + 10 Y11 + 5 Y12 + 12 Y21 +6 Y22 + 18 Y31 + 9 Y32 +6 Y41 + 3 Y42 SUBJECT TO C1) X11 + X12 + X13 >= 200 C2) X21 + X22 + X23 >= 200 C3) X31 + X32 + X33 >= 150 C4) - 300 NM1 + 1.67 X11 + 2.5 X21 +0.83 X31 = 2000 C8) Y21 + Y22 >= 1500 C9) Y31 + Y32 >= 1800 C10) Y41 +Y42 >= 1000 C11) - 300 NMH1 + 0.1 Y11 + 0.0833 Y21 +0.056 Y31 + 0.167 Y41
