HI! Can you solve this ASAP!

Queuing Models For each of the following systems identify the customers and servers, and specific type of queueing environment (characteristics of serven'queue interaction e.g. multiple severs servicing single queue, etc.) and give a reasoned initial guess as to the distribution of the service times and arrival times: Example: Checkout stand of a grocery store 0 customers = shoppers - servers = cashiers, there are c cashiers - each server has their own queue - arrival times should be exponentially distributed with a time varying rate to simulate increased arrival rates at lunch time, and for the after-work crowd - service time would be a constant multiplied by the number of items selected. 0 A grocery very small store would have a small number of items to choose from and so would have a binomial distribution. 0 A large store can use a Poisson distribution to approximate the binomial since the number of items in the store is large while probability of selecting any particular item is small
