Exercise 2: (Operations Research) Future Electronics Lid. manufactures four products: A, B, C and D. Each of the products must pass through the following departments before they are shipped: wiring drilling, assembly, and inspection. The time requirements in each department (in hours) for each unit produced and its corresponding profit value are summarized in the table below. The production time available in each department each month and the minimum monthly production requirement to fulfill the contracts are as follows: ISE 201 Future Electronics wants to maximize the total profit from the four products using a Linear Programming model, a) Define the decision variables. b) Define the objective function. c) Define the constraints
