Document Summary
The basis of waiting line analysis is the tradeoff between the cost of improved service and the cost of making customers wait. 4 basic structures vary by channels and phases. # of servers in sequence a customer must go through. Server: single-channel, multiple-phase, multiple-channel, single-phase, multiple-channel, multiple-phase. Arrival rate ((cid:540)) rate at which customers arrive at a service facility in a period of time the frequency at which customers arrive at a waiting line is usually described by a poisson probability distribution. Poisson process: a process in which events occur continuously and independently at a constant average rate where x = random variable representing the # customers arriving per time period k = # of arrivals e = 2. 7183. Service rate ((cid:541)) rate at which customers can be served in a period of time (can be used to derive the time required to serve each customer)
