What is Supply Chain simulation?

Supply Chain simulation is the process of modeling the behavior of a Supply Chain in order to evaluate different strategies before implementing them in reality. It is essentially a safe environment in which to rehearse decisions that would be costly or risky to experiment with live.

By creating a digital representation of the Supply Chain — its nodes, flows, lead times, capacity, and demand patterns — planners can test scenarios such as sharp demand variability, supplier disruptions, changes in inventory policy, or the addition of new production sites. The simulation shows how the end-to-end system would respond, not just individual nodes.

Simulation therefore helps companies move from reactive decision-making, where trade-offs are made under pressure, to proactive strategic planning where risks and opportunities have been modeled, compared, and debated before commitment.
