1. Consider an Amazon fulfillment center process: The orders must at the first step be reviewed by a staff once the order is received at this center via their order tracking software, which includes sending the order details to the warehouse to be picked up from the shelves, and sending the customer information to the print shop to print shipping and return labels for that order. Once this first step is complete, the warehouse picks up the items as per the order, and locates them in a box proportionate to the size of the items, and adds gift wrapping if asked on the order. Meanwhile, the print shop checks for the customer address in the database and fills in the label template that must be taped on the package for shipping and delivery. Another person at the quality control unit takes care of the last step, which is to verify the items to be the right ones by comparing them to the customer order sheet, and also by checking the label information for correctness, in which case s/he puts the label on the box, seals it, and puts it aside for shipment. The order processing is finished at this point for each order. The list of activities above is given in the table below: Activity Order reception and dispatch Warehouse (supply of the items, gift wrapping, and boxing) Labels printing for shipment Quality Control and sealing 2 3 A simple flowchart of activities above is provided below. 2 3 1-1.Every day 120 orders are received at this center. Consider a day to be 8 hours of operation, Find the flow rate of orders (inflow rate) at step 1 per hour and per minute. 1-2. The order reception (Step 1) takes 20 minutes in average. Find the average number of orders waiting at the reception (Step 1). 1-3. Observations also show that 5 orders are at some processing stage at the warehouse step (Step 2) at any point in time. How long does it take for each order to be supplied and located in the box with potential gift-wrapping (i.e., step 2 flow time)? 1-4.Consider the labels printing (Step 3) taking 10 minute in average, and the quality control and sealing step (Step 4) taking 5 minutes in average. Based on the given activity durations and the duration you have calculated in section 1-3, which path is a critical path in this process? Show your calculations toward making this conclusion 1-5. In order to keep up with the demand (i.e., 120 orders per day), calculate the takt time for this process (i.e, how many minutes at maximum it must take to complete this entire process for each order)?
