What is Arena simulation software? e
lc
o
m
Arena is an advanced simulation system that provides an interactive environment for e
building, graphically animating, verifying, and analyzing simulation models. With Arena,
you can design a unique Arena template that is specific to your particular project,
company, or industry. The template development features build on Arena’s natural
hierarchical structure enabling you to create new simulation tools in a graphical, easy-to-
use environment.
Within Arena’s template-building area, you create complete simulation building blocks,
called modules. These modules may be very simple, such as one that counts customers as
they leave a bank. Or you might build a highly complex module that captures all of the
activities at a shipyard dock. In fact, Arena’s hierarchy encourages you to take apart the
systems you study into their critical, basic elements, then combine these basic elements
into the more complex components and subsystems to be simulated.
The modules that you build are collected into libraries, referred to as templates. You may
use these templates in support of your own simulation activities, or you may share these
simulation tools with other modelers.
By encouraging this sharing of technology, Arena offers the opportunity for you, as a
simulation modeler, to create completely customized environments, without writing any
programming code. Novice modelers can access the power of simulation as a decision
support tool by working with terminology, modeling logic, and graphical animation that
are specially developed for their needs. Experienced simulationists can improve their
productivity and share the knowledge they have gained by capturing essential simulation
logic and quickly packaging it into a verified, reusable building block for future models.
As mentioned above, within Arena you have the ability to define new modeling
constructs, called modules, and to store them in libraries, referred to as Application
Solution Templates (AST’s), or templates.
If you are familiar with Arena’s model-building and analysis environment, you will find
that the template development features build on the concepts and interface you already
have learned. When you run Arena, you will simply open a Template Window (instead of
a Model Window). Select the File > New menu option or press the New File toolbar

button. In the dialog that is displayed, select Template Window and click OK, as shown in
Figure 1.1.
Figure 1.1 Arena’s Template Window selection
This template window serves as a “home base” for the activities involved in building a
template. The windows that you work with to define modules are displayed on the same
desktop as Arena model, input, and output windows. You interact with these windows
using the standard Arena user interface.
Intended audience
Before you begin to access the capabilities of template building, you should already have
developed a good understanding of the basic Arena modeling interface and the either the
SIMAN template or Arena’s Basic Process, Advanced Process, and Advanced Transfer
templates. This guide assumes that you are familiar with Arena modeling concepts and
terminology, which are presented in the Arena User’s Guide and online help.
About this guide
The Arena Template Developer’s Guide is designed to serve as both an instruction manual
for building templates and as a reference guide for the template-building features. We start
by presenting two chapters that familiarize you with the concepts and terminology
employed in Arena and walk you through a simple module-building tutorial. Following
this, we provide a description of the template window, then of each of the five windows
that you employ to build modules. Next we present Elements, the final concept related to
the definition of Arena modules. Appendix B of this book contains reference tables.
To begin your experience with template development, we recommend that you read
Chapter 2, “Arena Template Development Overview,” to become familiar with Arena
concepts and terminology. Then, follow the step-by-step instructions provided in the
module-building tutorial in Chapter 3. While you are building your first module, you may
want to refer to concepts presented in Chapter 2.
