Wally's Widget Warehouse takes orders from 7 A.M.to 7 P.M.The manager wants to analyze the process and has provided the process flow diagram shown below. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer and then they have to pack the order ready for shipping. Wally promises that every order placed today gets shipped tomorrow. That means that the picking and packing operation must finish all orders before they go home.
1. Order Taker (100 customers /hr)
2. Pick Order (80 customers/hr)
3. Pack Orders (60 customers/hr)
Questions:
A. What is the current maximum output of the process?
Take Order: (100 cust/hr) * 12 = 1200
Pick Order: (80 cust/hr) * 12 = 960
Take Order: (60 cust/hr) * 12 = 720
answer would 1200 since this number is largest, the Pick and Pack steps will have to stay all night until their steps are completed
B. How long will the picking and packing operations have to work if we have a day with the
Using 1200 as max:
Pick: 1200 widgets/ (80/hr) = 15 hrs
Pack: 1200 widgets/ (60/hr) = 20 hrs
<THIS IS WHERE I'M HAVING TROUBLE>
C. What is the maximum number of orders waiting to be picked?
Since order taker can take 100 orders/hr and Picker can only process 80/hr -- there will be a backlog of 20 per hour. A 12 hr day (7am-7pm) is used: so 12*20 = 240 orders
D. What is maximum number of order waiting to be packed?
Again, a bottleneck of 20 per hour : 240 orders?
E. If we double the packing capacity (from 60 to 120 orders per hour), what impact does this have on your answers in parts b, c, d?
??? havent gotten this far, want to make sure C and D are correct first
Thanks for any help/input -- i just want to make sure I'm on the right path
