4 Basic Queues and Servers

4-8

Serial Connection of Queues

Two queues connected in series might be useful if you are using entities to model items

that physically experience two distinct sets of conditions while in storage. For example,

additional inventory items that overflow one storage area have to stay in another storage

area in which a less well-regulated temperature affects the items' long-term quality.

Modeling the two storage areas as distinct queue blocks facilitates viewing the average

length of time that entities stay in the overflow storage area.

A similar example is in “Example of a Logical Queue” on page 4-9, except that the

example there does not suggest any physical distinction between the two queues.

Parallel Connection of Queues

Two queues connected in parallel, in which each entity arrives at one or the other,

represent alternative paths for waiting. The paths might lead to different operations,

such as a line of vehicles waiting for a tollbooth modeled and a line of vehicles waiting on
