SimQuick must be used for this problem
Management wants to study the performance at a local Dairy King DK restaurant during its second shift, : am to :
pm The two main areas under study are: drivethru and dinein The process at the drivethru works as follows. Cars arrive
and line up to place an order. It has been observed that the time between car arrivals is described based on the following table:
There is only room for eight cars to line up The time to place an order, based on historical data, is summarized in the following
table.
Cars then move forward to a single window, at which they pay and pick up their order. Two cars can fit between a car placing
an order and another car at the paypickup window. The amount of time a car sits at the paypickup window can be
approximated by an exponential distribution with a mean of minutes.
The dinein process works as follows. The time between the arrivals of walkins can be approximated by an exponential
distribution with a mean of minutes. The number of customers per arrival, based on historical data, is provided below.
The inside line can hold about people. DK currently operates with cashiers. The amount of time for a cashier to serve a
single customer can be approximated by a normal distribution with a mean of minutes and a variance of minutes.
Then, customers will find a table to eat. Assume that there is unlimited capacity.
Build a SimQuick model of the drivethru dinein that simulates the DKs second shift, perform simulations. Assume that
at am there are two cars in line to place an order and four walkin customers in line to place an order.
On the View Results window, below the simulation report, answer the following questions:
Report the overall mean throughput for the drivethru and dinein What do they represent?
Report the overall mean cycle time on the drivethru.
Report the overall mean service level at the drivethru and dinein What do they represent?
Estimate the number of cars in the order line at :pm Describe how you computed this value.
Estimate the number of walkin customers in the order line at : pm Describe how you computed this value.
