Manufacturing and supply chain simulation, since 1990.
We build simulation models and decision apps for lines, plants, warehouses and supply chains, so you can see what a change would do before you make it.
Some of the teams we have modeled for
What we do
We work in ExtendSim®, Plant Simulation, ReliaSim® or your team's own tool, and build one when none fits.
- Simulation consulting
A model of a line, plant, warehouse or supply chain, built to answer one decision.
- Custom applications
The model, wrapped in an app your planners run themselves. One of ours now serves every plant of a global manufacturer.
- Simulation libraries
Tested equipment blocks your modelers reuse, kept current by us.
- Training
ExtendSim, Plant Simulation and ReliaSim, online or on-site. For more than a decade we built and ran Imagine That's discrete-event training course.
Work we can show you

Olive plant capacity
Where's the real bottleneck in an olive plant?

Robotic warehouse design
Which layout and task rules work best in a robotic warehouse, before it's built?

VINLogic vehicle distribution
How do you move new vehicles from plant to dealer with less inventory in transit?
Discrete rate simulation started here.
A bottling line moving 1,000 containers a minute behaves like a flow of product. Andy Siprelle built bulk flow simulation in 1990 to model it that way, and the idea became discrete rate simulation, now a standard method for high-speed and bulk flow.
Our work has been published with P&G and Union Pacific, and built on or cited by Y-12 and Boeing.
Tell us your problem
What would happen if you changed it?
Describe the decision in front of you. We'll tell you whether a model can answer it, and what it would take.
- A straight answer on whether simulation is the right tool
- Which tool fits, even if it isn't one we use every day
- A rough scope and timeline, before any commitment
