What is SES/workbench?
• SES/workbench is a general-purpose
simulation modeling tool
• Allows models of complex systems to
be built and executed graphically
• Predicts performance problems early
in engineering design cycle
• SES/workbench anticipates the
behavior of complex systems by
simulating individual events

Performance Modeling
• SES/workbench allows you to:
– Model and simulate complex systems at various levels of
design or abstractrion
– Gain a greater understanding of your system
– Guarantee that design performance meets requirements
– Analyze alternative approaches and tradeoffs through
“what-if” analysis
– Identify performance problems early in the design phase

Systems Analysis
• SES/workbench is used to study:
– Workflow through a system
– Time relationships of work in a system
– Resource utilization
– Competition for resources
– Optimal system configurations
– End-to-end response times

Graphical User Interface
A simulation model is constructed by drawing
and connecting nodes with arcs to represent
your system being modeled
Copyright ©1999 Hyperformix, Inc. All rights reserved.
Customizable Specification Forms
Each node and arc has a
corresponding specification form
where the modeler specifies the
parameters that describe the
behavior of that node for your
system

Built-In Probability Distributions and
Queueing Disciplines
SES/workbench provides a variety of probability distributions
and queueing disciplines to aid in simulation construction.
Probability Distributions:
bernoulli
beta
binomial
empirical
erlang
exponential
gamma
geometric
hyperexponential
lognormal
normal
poisson
triangular
uniform
Weibull
... and
more
Queueing Disciplines:
Priority Rules

Time Rules
first come first serve
last come first serve
round robin
processor sharing
Powerful User Extensions
Modelers may represent
unique system behaviors by
extending the functionality of
the graphical modeling icons

Rich Simulation Environment
Animation allows the user to watch the
model execute graphically
• View work as it
flows through the
system, ensuring
correct model
functionality
• Precisely control
the execution of
the simulation
engine, including
break and trace
capability.

Rich Simulation Environment
Inspectors allow the modeler to view
dynamic statistics during model execution
• Gather statistics on
workload,
environment and
system performance
• Inspect the
current work in
your system
• Determine system
bottlenecks and
areas of performance
problems

Rich Simulation Environment
Statistics provide performance data that permits
verification, debugging and optimization
SES/workbench supports many types of
statistics and users may even define their own

Read/Write API
A Query Language provides access to model and
statistical result data without the use of the
graphical user interface
