Waiting Line Models Waiting Line Models Chapter 14 Chapter 14 AHS Introduction Basic Modeling Approaches Analytical Searching for mathematical formulas that describe the operating characteristics of the system. Relatively complex to solve, unless we make some simplifications Simulation Possible to analyze more complex systems, without a need to make many simplifying assumptions Spreadsheet modeling, not a very suitable tool for queueing simulation models. Many good software packages available for simulation of queueing models
