Question 1: (60 pts) An automobile engine cylinder manufacturing company plans to manufacture four types of cylinders: a basic engine cylinder, a high technology cylinder, a sports carcylinder and a luxury car cylinder. The marketing department has determined to produce 1800, 2000, 1100 and 1500 units of the basic, high-tech, sports, and luxury models, respectively according to the demand forecast. The facility plan department wants to design a plant and decide the number of equipment to purchase. Three machine types and three material handling systems are available for performing the three operations and transporting products. The cylinder models require one or more of three operations, and and the total required numbers of each type of operation are 6000, 5000 and 4000 respectively to produce the all of the demands. Finished goods are transported using either of two material handling systems The costs of machines and are $280,000, $220,000 and $250,000. The costs of the material handling carriers are $90,000, $80,000 and $70,000 respectively. The available budget for equipment is $8,000,000. The following two matrices show the operating cost. : The cost of performing operation on production equipment : The cost of handling product type using the material handling system The time required to perform operation on machine is inversely proportional to the corresponding cost, = 8/. Similarly, 代写Fall 2024 IE 360 Facilities Planning and Design the time required to transport on material handling system is inversely proportional to the corresponding cost, = 1/. Each machine is available for 700 unit time and each material handling system is available for 700 unit time. a) Implement the integer programming model to minimize the total cost using cvxpy on python. Copy and paste your .py codes in the below box. .py code b) What is the optimal objective value? What is the optimal quantity of each production and handling equipment?

Suppose we want to produce 500 units per hour and assume the machines are effectively 90% reliable. Fill in the table and develop a rough estimate for the number of each type of machine that will be required.
