Service Systems
A service system is a system in which customers present themselves, are serviced, and depart. For example, an airline ticket counter is a service system. Service systems are very common in business, and knowing how to model a service system’s capacity is an important skill for a modeler.
As common as service systems might seem, they are actually even more common. For example, a telephone switch is a service system — and so is the printer and copier in that little room down the hall from your office. So modeling service systems is even more important than you might think at first.
In this session, we’ll study single-server systems, probably the simplest form of service system, but also the most common. We’ll give you the tools you need to model them with enough fidelity that your models will make useful predictions of their capability and capacity. This is just what you need to determine whether these systems fulfill — or over-fulfill — the needs of the businesses they serve.

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.
