It takes 3 minutes for a bartender to fill the order. When the kitchen and bar orders are both ready. A waiter takes them to the room and bills the guest. There are six waiters to provide the service, and each order takes 20 minutes for the waiter to complete.

a. Capacity of each resource

Service manager capacity=60/2 minutes per order

Service manager capacity=30 orders per hour

Each chef capacity= 60/16 minutes per order

Each chef capacity= 3.75 orders per hour

4 chefs capacity= 4 ×3.75

4 chefs capacity= 15 orders per hour

Bartender capacity= 60/ 3 minutes

Bartender capacity=20 orders per hour

Each waiter capacity=60/20 minutes

Each waiter capacity=3 orders per hour

6 waiters capacity=6×3

6 waiters capacity=18 orders per hour

Based on the above calculation we can see that the minimum capacity will be the kitchen as the kitchen can only handle capacity of 15 orders per hour, which therefore means that the Bottleneck is the Kitchen .

b. Throughput time = 2 + 16 + 20

Throughput time = 38 minutes

c. Orders that are in the system on average on Friday nights

Using this formula

I = T ×R

Let plug in the formula

I= 10 ×38/60

I = 6.33 orders

d. The total labor costs

Waiters= 6 x 9 = 54

Cooks=4 x 15 = 60

Bartender=1 x 10= 10
