Witness Horizon

Consistently the most flexible, powerful, proven process simulation technology in the world, Lanner’s desktop modelling studio, WITNESS Horizon, enables professional modellers to rapidly develop feature rich models and simulation apps that provide unparalleled insight through dynamic data visualisation and freedom to test choices in a risk free virtual environment.

Powerful Model Building Elements

Get your models up and running in no time with a wide range of standard modelling elements with unique logic controls and easy configuration.

Discrete Event and Continuous Modelling

Combine continuous flows with discrete events within models to address a wide range of business problems in the most efficient and appropriate way possible. Continuous elements enable the modelling of processes that include fluids flowing through pipes or tanks and situations where high volumes of parts pass through processes at speed which can be more easily represented as fluid flows.

2D and 3D Modelling Environment

Design your model layout and develop logic efficiently in a 2D plan view before switching to stunning 3D visualisation at the touch of a button. WITNESS Quick3D™ is powered by Virtalis Visionary Render to deliver an exceptional immersive model experience and virtual reality performance.

Simple, Powerful Logic Coding

No need to delve deep into complex coding to define and structure your logic. WITNESS lets you develop your logic in compartmentalised modular blocks directly within building elements. More powerful coding techniques can be leveraged through the versatile WITNESS Action Language. WITNESS also supports external code libraries written in common languages such as C++, C# & VB.net.

Embedded Business Intelligence

Get to the heart of model insights and communicate answers stakeholder questions through inbuilt charts and reports that make WITNESS the ideal predictive analytics platform for business transformation. Easily export simulation data for external analysis in your favourite BI tools.

Multi-core Processing

WITNESS offers support for multi-core processing of model execution allowing users to run parallel replications and experiments and deliver accurate results, insight clarity and outcome certainty for stakeholders in a suitable timeframe.
