Study Notes

Understanding Queuing Systems

  • A queuing system consists of three elements: arrival process, service process, and queuing discipline.
  • The most common format for classifying queuing systems is A/B/S/K/E, where A specifies the arrival process, B specifies the service process, S specifies the number of servers, K is the maximum number of customers allowed into the system, and E is the queue discipline.
  • The symbols used for this classification system include M, D, Ek, G, FIFO, SIRO, PRI, and GD.
  • Transition rate is the rate at which the system moves adjacent states, and forward transition moves from state K to state K+1, while backward transition moves from state K to state K-1.
  • The transition rate for M/M/1, a single server queue system, can be represented in a diagram using λ (mean arrival rate) and µ (mean departure rate).
  • Common queue problems include single line-single server, single line-multiple server, multiple line-single server, and multiple line-multiple server.
  • Queue operation involves two types of operations: arrival and departure.
  • The aim of studying queue systems is to simulate the system to determine the number of service stations that minimize queue length and time spent in the queue, while maximizing service station utilization.
  • Total cost of a queue system includes the cost of facility idle time and the cost of patient waiting time.
  • Queue system parameters include waiting time, average number in the queue, and average waiting time.
  • Waiting time is the time from the instant a patient joins a queue until it leaves it for service.
  • Average number in the queue is the sum of waiting times of customers divided by the total time.
