Supermarket Checkout

I have to submit this project by 20th Wednesday 6 AM.

Supermarket Checkout

A big supermarket chain wants a simulation of their checkouts. They regularly face questions such as:

• If we use six checkouts instead of five, how much does that reduce the waiting time for each customer?

• Is it worth it?

• Is it useful to open another "5 items or less" checkout? Or should it be "10 items or less"?

There is some new technology on the market:

scanners that would reduce the scanning time for each item (they are much more reliable). But three of the new scanners cost as much as five of the old ones –

• is it worth buying them?

• Does that really make a difference?

They want you to simulate checkout queues to answer these and similar questions.


Your implementation should allow for:

• a variable number of functioning checkouts (1 to 8).

• the number of products for each trolley to be generated randomly within a user specified range (1 to 200).

• the time for each product to be entered at the checkout to be generated randomly within a user specified range (.5 to 6).

• one or more checkouts to have a restriction on the number of items e.g. "5 items or less".

• the rate the customer arrive at the checkouts to be generated randomly within a user specified range (0 to 60).

Your implementations should record the following:

• total wait time for each customer

• total utilization for each checkout

• total products processed

• average customer wait time

• average checkout utilisation

• average products per trolley

• The number of lost customers (Customers will leave the store if they need to join a queue more than six deep)

A skeletal implementation of a graphical checkout application has been provided. You do not have to use this code and are free to change it or develop your own independently. A separate thread must be used for each checkout with a appropriate synchronization scheme of your choosing.

Your solution should provide both safety and liveness.
