| Modeling waiting lines | 12/9 Session Links |
When we model waiting lines, we make several critical assumptions that make the model simpler, and they’re listed above. The most important is the assumption of equilibrium, which says that the system has been operating for a very long time, and all transients have died out. This assumption leads directly to the Fundamental Balance Equation, which expresses the idea that the probability of a new customer arriving when there are n-1 customers in the system is equal to the probability of a customer departing when there are n customers in the system. If these two probabilities are equal for all n, then the system is in balance.

Modeling service systems in general is extraordinarily complex, but as we’ve seen, if we make reasonable approximations, we can gain powerful tools that are very easy to apply. In the case of service systems, we assumed that the system was at equilibrium or close to it. Analogously, we can make simplifying assumptions for many other complex questions. Examples are process control, resource scheduling, resource allocation, cost allocation, vehicle routing, and many more.
