Process: How many customers?
Dining Area - 112 seats
It takes 60 minutes for one customer to eat dinner, and there are 112 seats in the dining area. Therefore 112 people eat every 60 minutes (throughput). On average a dinner cycle is completed every 60 minutes/112 people = 32 seconds per person (cycle time). We know that dinners are processed in batches of 8, so on the average a table of 8 finishes every 256 seconds (processing time).

Cash flow

  

$8,036 per day

Module B: Operations: Pilkington: 2013: 7

112 diners at $8 each (average lunch and diner) 112 drinkers at $2.25 (1.5 dinks each) Cash flow: $1,148 per hour For 7 hours a day (lunch and evening)

Role of the bar: batch and flow

Module B: Operations: Pilkington: 2013: 8

To send 8 people into the dining area every 256 seconds means that the bar must also process 112 customers an hour. Assumption: If they have 2 drinks and each one takes 12 minutes How many should the bar seat?

Role of the bar

The bar needs to empty every:

24/60 = 0.4 of an hour

This means it should seat:

112 x 0.4 = 44.8 people
Module B: Operations: Pilkington: 2013: 9

How many can sit in the bar shown on the diagram?


Operations management thinking applies not just to manufacturing    
