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 following process flow diagram. 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 to ready it for shipping. The order-taking step works at a maximum rate of 100 customer orders per hour. Order picking works at a maximum of 80 per hour, and packing works at 60 per hour.

Wally wants to figure out the following:

a. What is the current maximum output of the process assuming that no one works overtime? (For your answers to these questions, assume that everyone can start working at 7 A.M.)

b. How long will the picking and packing operations have to work if we have a day where the order taker works at his maximum capacity all day?

c. Given

b, what is the maximum number of orders waiting to be picked?

d. Given

b, what is the maximum number of orders waiting to be packed?

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), and (d)?LO11-2
