Type of customers - Prepared/unprepared customer, Big/small orders, high/low maintenance customers, Paying cash vs. check o Single: FCFS, sense of fairness o Multiple: jockeying Discipline/Priority Rules o First come, first served o Earliest due date or shortest processing time o Reservations or appointments possible? o Emergency situations? o Preemptive discipline (VIP lines, frequent fliers) Finite vs. Infinite Populations, Balking, Reneging, Jockeying Queuing Problems - Slides and Problem Set Know how to do all of the problems on the Additional Problem Set Lab Exercise #3!!! VERY IMPORTANT Be able to solve all of these problem types: A. Arrival and Service Rates, Service Utilization Factor - What are they? Calculate them. Be able to read Arrival and Service Rates. Be able to covert to /hour, per minute, and per second. B. Single Server Models - Formulas (n, t, l, s, P), interpreting data C. Multiple Server models - Interpreting data (Rather than making long lists, concentrate on practicing problems. Understand underlying themes.) Be aware that the primary examples given in the lecture and charts or illustrations used in class may also be tested.
