Problem 16. (10 Points) Consider the following diagram of a fast food re car following the path described by arrows lowing diagram of a fast food restaurant drive-through with three stops for each owing the path described by arrows in the diagram below. The time required to complete the work at each of these workstations is also listed on the diagram: Restaurant drive-through operating three stations Menu board First window Second window ????? Take meal order (2 min.) Drive through Process payment (1 min.) Drive through Assemble, and provide meal order (3 min.) Exit 1. What is the maximum rate at which this restaurant can successfully serve arriving cars with this product layout? 2 + 1 + 3 - 6 mins. 60 - O customers per hour Q- 20customers -L Cele > 3 Tine 2. An average of 15 cars arrive each hour at the restaurant drive-through. What does this imply about the efficiency of this drive-through layout? ESHiciency in U. 6 : 2 - 7 3. The employee who works at the first window, where the cars payment is processed, has just left the restaurant due to a family emergency. To keep operating, the restaurant has closed the first window and the employee at the second window is now doing the work required at both windows, processing payments and assembling and providing the meal to each of the cars. Now, due to this change, what is the maximum rate at which this restaurant can successfully serve arriving cars? 13 Version AExplanation / Answer
1) Max production rate = bottleneck of the process = 3 min
So it can take 3 min between two fnished order
2) Store has cycle time of 3 min since this is bottleck of the process
So it can handle max = 60 / 3 = 20 car per hr
Efficiency of 15 car entering = 15 / 20 = 75%
3) Process 1 = ( 1 + 2 = 3 min)
Process 2 = 3 min
since bottleneck has not been changed, there is no change in the max service rate which will remain at 3 min
