Question
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 operations must finish all orders before they go home. Customers Customer Orders Picked Orders Wait for Shipper Order Taker Pick V87--- Orders Pack Orders 100 Customers/ hour 80 Customers/ hour 60 Customers/ hour Wally wants to figure out the following. a. What is the current maximum daily output of the process assuming that no one works overtime? (i.e., meaning all three operations work a 12-hour shift) Current maximum output 720 units per day b. How long (in hours) will the picking and packing operations have to work to finish all the orders that were taken if we have a day where the order taker works at his maximum capacity? Pick orders Pack orders 15 hours 20 hoursExplanation / Answer
A) The bottleneck of the system is 'Pick Orders' working at 60 customers/hour. Considering the 12 hour work schedule of the process, the Current Maximum Output = 12*60 = 720
B) The Highest capacity in Process = Capacity of 'Order Takers' = 100 customers/hour.
Considering the 12 hour work schedule of the process, the number of orders taken over the day = 100*12 = 1200
Time Taken by 'Pick Order' to fulfill the maximum capacity of 'Order takers' = Max Order taken/Capacity = 1200/80 = 15 hours
Time Taken by 'Oack Order' to fulfill the maximum capacity of 'Order takers' = Max Order taken/Capacity = 1200/60 = 20 hours
C) Max Capacity of 'Order Pick' in 12 hour= 12*80 = 960
Max Number of orders waiting to be picked = Max Capacity of 'Order Taker' - Max Capacity of 'Order Pick' = 1200-960 = 240
D) Max Capacity of 'Order Pack' in 12 hour= 12*60 = 720
Max Number of orders waiting to be packed = Max Capacity of 'Order Taker' - Max Capacity of 'Order Pack' = 1200-720 = 480
E) The Highest capacity in Process = Capacity of 'Order Pack' = 60*2 = 120 customers/hour.
Considering the 12 hour work schedule of the process, the number of orders taken over the day = 100*12 = 1200
Time Taken by 'Pick Order' to fulfill the maximum capacity of 'Order takers' = Max Order taken/Capacity = 1200/80 = 15 hours
Time Taken by 'Oack Order' to fulfill the maximum capacity of 'Order takers' = Max Order taken/Capacity = 1200/120 = 10 hours
F) Max Capacity of 'Order Pick' in 12 hour= 12*80 = 960
Max Number of orders waiting to be picked = Max Capacity of 'Order Taker' - Max Capacity of 'Order Pick' = 1200-960 = 240
G) Max Capacity of 'Order Pack' in 12 hour= 12*120 = 1440
As Max Capacity of 'Order Pack' in 12 hour > Max Capacity of 'Order Take' in 12 hour, there will be no orders waiting to be packed. Answer : 0 units.
