Problem 2: As a building designer, you have been asked to analyze and select the best
window frame type alternative-either aluminum or steel. The project is located in a remote
area, and the nearest industrial area hosting steel and aluminum windows frames
manufacturers is 250 km away. All project windows are identical, and the circumference of
the window frame is 6.2 meter. A crew of two labors is required to manufacture one steel
frame. It takes 2.5 hours to manufacture the first window every day, and the learning rate is
0.9. The number of production units is per day is limited to 8. The weight of steel is 12 kg per
meter, and the weight of aluminum is 4.5 kg per meter. The cost of steel is 0.4 OMR per kg
and the cost of aluminum 1.1 OMR per kg. If 45 windows frames are required for the project,
the crew cost is 3 OMR per hour for steel frames and 3.6 for aluminum frames, and the
transportation, price is 0.01 OMR per kg per 50 km, which alternative would you select?
