Activity 5: Linear Programming – Graphical Method Solve the following Linear Programming problems using the graphical method. Use the PHPSimplex application software. 1. An appliance manufacturer produces two models of televisions: Colored TV and B&W TV. Both models require fabrication and assembly work; each colored TV uses four hours of fabrication and two hours of assembly; each B&W TV uses two hours of fabrication and two hours of assembly. There are 600 hours fabrication available per week and 480 hours available of assembly. Each colored TV contributes P1200 to profit and each B&W TV contributes P900 to profits. How many-colored TV and B&W TV must the manufacturer produce in order to maximize the profit? 2. An animal food producer mixes two types of animal food: X and Y.

Prepare a workforce schedule for these individuals so that each will have 2 consecutive days off per week and all staffing requirements will be satisfied. Give preference to the S-Su pair in case of a tie. (Note: If there is a tie that cannot be broken by following the preference to the S-Su pair, choose the pair closest to the beginning of the considered week.) The minimum number of workers is 7 workers. (Enter your…

7. Using the assembly-line balancing procedures for any assembly-line balancing problem, which of the following is most correct? Multiple Choice The theoretical minimum number of workstations is always less than number of workstations actually used. The theoretical minimum number of workstations is sometimes more than number of workstations actually used. The theoretical minimum number of workstations is sometimes less than Y and sometimes more than number of workstations actually used. The theoretical minimum number of workstations is always less than or equal to number of workstations actually used. The theoretical minimum number of workstations is never less than number of workstations actually used.
Situation: One other significant problem plagued the engineering departments at TRP. Because ofpast salary increase practices, there is now a high salary gap between the engineermanagement levels and the engineering designers. For the same long working hours, thoseworking in the operational levels (e.g., payroll, accounting, HR) made almost 15 times less thanthe engineering designers. These same operational level employees also made 25 times lessthan the engineering management groups. Alternative Courses of Action for payment gap between workers with the same working hours: ?
