2 Building Simple Models with SimEvents Software

entities try and fail to advance along that same entity path. For example, an entity

departs from a queue and, simultaneously, the next entity in the queue tries and fails to

depart.

Data and Signals

In time-based dynamics, signals express the outputs of dynamic systems represented by

blocks. Event-based blocks can also read and produce signals. One way to learn about

signals is to plot them; the discussion in “Explore the D/D/1 System Using Plots” on page

2-19 is about visualizing signals that reflect behavior of event-based blocks.

Time-based and event-based dynamics can interact via the data shared by both types

of blocks. Attributes of entities provide a way for entities to carry data with them. The

subsystem in “Lesson 3: Add Event-Based Behavior” on page 2-35 illustrates the use of

attributes in the interaction between time-based and event-based dynamics.

Although signals are common to both time-based and event-based dynamics, event-

based dynamics can produce signals that have slightly different characteristics. For more

information on event-based signals, see “Role of Event-Based Signals in SimEvents”.
