Four machines (A, B, C, and D) are arranged in a production line to manufacture a specific product. Each machine has distinct operational rules and performs a different function in the manufacturing process. The factory works from 9:00 AM to 5:00 PM every day, and each product must pass through the machines in a specific order to be completed. Each machine has a fixed processing time per product, but a machine cannot process more than one product at a time.

Information about the machines:

• Machine A: Takes 10 minutes to process a product. Products enter at 7-minute intervals starting at 9:00 AM.

• Machine B: Takes 15 minutes to process a product. It starts working only after Machine A has completed its task and sends the product forward.

• Machine C: Takes 20 minutes to process a product. It requires a 5-minute cooldown period before processing the next product.

• Machine D: Takes 12 minutes to process a product. It can only start processing a product if it receives it before or exactly on the half-hour mark; otherwise the product waits until the next half-hour mark.

The factory stops accepting new products for processing at 4:00 PM.
