1. Consider a service station in which customer arrives in accordance with a non homogeneous Poisson process with intensity function λ (t), t 0. There is a single sever and upon arrival a customer either enters services if this server is free at that moment or else joins the waiting queue if this server is busy. When the server completes serving a customer, it then either begins serving the customer that had been waiting the longest if there are any waiting customers, it remains free until the next customer arrival. The amount of time it takes to service a customer is a random variable having probability distribution G. There is a fixed time T after which no additional arrivals are to enter the system, although the server is free at time T. Define variables and events to analyze this model and give the suitable procedures. (20 marks) 2. Draw the flow diagram for simulating the single server Queue. (10 marks) 3. Consider a two-server system in which customers arrive in accordance with a non homogeneous Poisson process, and suppose that each arrival must first be served by server 1 and upon completion of service at 1, customer goes over to server 2. If server 1 is free, customer can enter service at server 1 or join the queue of server 1. After completion services at server1, it can enter server 2 if server 2is free. The service time at server i have distribution G , i=1,2. Define variables and event lists to analyze this model and give the procedure for this system. (20 marks) 4. Consider a model in which customers arrive at a system having two servers. Upon arrival the customer will join the queue if both servers are busy, enter service with server 1 if that server is free, or enter service with server 2 otherwise. When the customer completed service with a server (no matter which one), that customer then deports the system and the customer that has been in queue the longest (if there are any customers in queue) enters service. The service distribution at server I is G , i=1,2. Customer arrives in accordance with a non homogeneous Poisson Process. Define variables and event lists to analyze this model and write the procedure for this system. (20 marks) 5. Consider a shop that stocks a particular type of product that it sells for a price of r per unit. Customers demand in accordance with a Poisson process with rate λ and the amount demanded by each one is a random variable having distribution G. In order to meet demands, the shopkeeper must keep an amount of the product on hand and if the on-hand becomes low, additional units are ordered from distributor. If present inventory level is x and no order if outstanding, then if x<s, the amount s-x is ordered.
