WITNESS is the world's leading soware product in the field of
visual interactive simulation. In Witness we can model, simulate
and optimise Discrete event processes, like manufacturing plant
processes, supply chain & logistics etc. More than 6500 licenses
have been sold worldwide across all industry sectors. The system
is also widely used within education.
WITNESS models: A WITNESS model consists of a collection of
WITNESS elements, together with the control logic (rules and
actions) that ensure that the model performs in the same way as a
real-life system. Some of Witness elements are;
Physical elements: WITNESS provides elements that represent
·Elements that move through the model, being processed (parts and
·Elements that transport parts and fluids (conveyors, track, vehicles,
carriers, paths and pipes).
·Elements that store parts and fluids (buffers and tanks).
·Elements that process parts and fluids (machines and processors).
Logical elements: WITNESS also provides elements that
represent intangible objects:
·Elements that represent shift patterns (shifts).
·Elements that provide statistical variation (distributions).
·Elements that provide a source of data outside the model (files).
·Elements that are referenced in the model's control logic (variables,
attributes and functions).
Finally, WITNESS provides elements that enhance the presentation
of the model and supply information about the state of the model
while it is running:
WITNESS incorporates statistical data in the form of
distributions. WITNESS provides a set of distributions that return
There are 3 integer distributions, (such as a quantity of parts):
BINOMIAL, IUNIFORM and POISSON.
There are 11 real distributions, (such as a time or a
measurement): BETA, ERLANG, GAMMA, LOGNORML, NEGEXP, NORMAL,
TRIANGLE, UNIFORM and WEIBULL.
You can create your own distribution too.
Sigma Ratings in WITNESS:
WITNESS includes function called SigmaRating that allows you to
calculate and use your own Sigma ratings based on a 'number of
defects per million opportunities' parameter. Apart from this we
could incorporate many more functions in WITNESS.
WITNESS Quick3D™ allows the creation of a 3D view of a model with
just a single click.The 3D model can be
simultaneously simulated with the WITNESS simulation run.
WITNESS supports CAD and XML imports and includes linkage options
to and from a wide range of platforms. Wizards enable easy
connections with Excel and a wide range of databases such as
Oracle, SQL Server, Access, etc. WITNESS also features methods to
control simulations using VBA, C# and other options for simulation
Comprehensive Experimentation with Optimization.
WITNESS Experimenter API provides access to the
optimization and experimentation functionality. Set objectives,
parameters and constraints to find the best solutions for your
Comprehensive Reporting: Statistics such as element counts,
utilization, queue limits etc., are all shown at the touch of a
button in a variety of configurable tabular and chart formats.
Witness is widely used in modeling, simulation & optimization of
processes, in manufacturing industries and supply & logistic chain
