QUEUEING THEORY AND MODELING
1 QUEUEING THEORY AND MODELING Linda Green Graduate School of Business,Columbia University,New York, New York 10027 Abstract: Many organizations, such as banks, airlines, telecommunications companies, and police departments, routinely use QUEUEING models to help manage and allocate resources in order to respond to demands in a timely and cost-efficient fashion. Though QUEUEING analysis has been used in hospitals and other healthcare settings, its use in this sector is not widespread. Yet, given the pervasiveness of delays in healthcare and the fact that many healthcare facilities are trying to meet increasing demands with tightly constrained resources, QUEUEING models can be very useful in developing more effective policies for allocating and managing resources in healthcare facilities.
hospital beds. Largely because of this perception, the number of hospital beds has decreased almost 25 percent in the last 20 years. But determining bed capacity based on occupancy levels can result in very long waiting times for beds (Green 2003). In all queueing systems, the higher the average utilization level, the longer the wait times.
