AKP Online takes orders from 7am to 7pm daily. Customer orders arrive one by one evenly throughout the day from 7am to 7pm at the rate of 1000 orders per hour. There are three steps to ship a customer order. View the process flow diagram shown below. The capacity of each step is shown in the process flow diagram. The first step is to take the order (1000 orders per hour). The second step is to pick the order (800 orders per hour), and the last step is to ship the order out (600 orders per hour). AKP promises that every order placed today gets shipped today. That means that the picking and shipping operation must finish all orders before they go home. The buffers between the steps are sufficiently large such that there is no blocking at any time.
