Assignment:
Panchero's restaurant has two items on their menu: Fajitas and Quesadillas. The serving process is as following: customers form two lines to order the food (ORDER), wait for the food to be packaged (PACKAGE), make payment (PAY), and fill their drinks and take fork and napkins (FILL). Since customers don't have choice of meat and vegetable when they order Quesadillas, the PACKAGE stage for Quesadillas is shorter than for Fajitas.
The restaurant serves dinner from 6 to 9 pm. From 6 to 8 pm, 60 customers per hour order Fajitas and 40 customers per hour order Quesadillas. From 8 to 9 pm, 40 order Fajitas and 30 order Quesadillas. The processing rates are specified in the process flow diagram:
a) Identify the throughput rates of the process for Fajita and Quesadilla, respectively?
b) Draw an inventory buildup diagram. At what time would the last customer leave the system?
