Discrete Event Simulation

Modelling for better operations scheduling and throughput optimization

Model operations using discrete events simulation

Do you need simulation?

How to determine the effective or maximal throughput, identify the bottlenecks or in which situations the bottleneck moves, establish the best schedule or evaluate if there are enough resources?
Will it be possible to deliver on time, is it possible to reduce costs, what is the most desirable expansion scenario?

These are typical questions expressing an underlying need to model operations using simulation.

The power of Discrete Events Simulation (DES):

a global view for fact-based decision-making

DES allows to understand and model operations for which time, variability, movement and resource availability are critical elements. Discovering underlying interactions and key drivers provides intelligence on the whole process.

Model operations using discrete events simulation

A globally recognized expertise

Our consultants have extensive experience in developing complex models for many applications. In addition to having developed unique specialized libraries for bulk materials simulation, traffic and maintainability, they have published scientific peer-reviewed articles and participated in several international conferences.

Our modeling approach is practical. We make decision-making tools accessible and democratic, easing the configuration of scenarios and the interpretation of results.


Expand on your simulation knowledge by reading about our framework which combines lean, statistics and programming.  Sharing our knowledge with our clients is part of our culture. We offer training sessions on the practical use of simulation.

See What Our Clients Have To Say

I had the opportunity to work with Vincent to optimize our production planning and scheduling process using simulation. The simulation helped us to discover and address bottlenecks, hence targeting the adequate capital investments. The power of the simulation tool allowed us to easily perform what-if scenarios.  We were able to study the capacity of our production assets with respect to the various products and packaging formats to handle.

As part of a peer review team doing a review of the mining project, I’ve come across your report and I’m impressed which typically isn’t the case with simulation results as I’ve seen some fairly average work and some very good work.
