Consider a laundry service that has 3 steps to its process.

Step 1 is Washing, Step 2 is Drying, Step 3 is Ironing & Step 4 is Packaging.

Step 1 Washing is a batch operation, with a batch size of 50 pieces of clothing, variable time of 15 seconds per piece and a fixed time of 20 minutes. There is one washing machine.
