Simulation and decision - Ontologie Documentation

At a glance

The Simulation module lets you test hypotheses on your data without impacting production. Create "what if" scenarios, run temporal simulations, and use solvers to find the optimal configuration. Compare results side by side before deciding which changes to apply.

Concrete example: you manage a supplier network and want to evaluate the impact of a 10% price change. Create a scenario, apply the modification virtually, observe the cascading effect on orders and margins, then decide whether or not to apply the change.

What you will do

Key vocabulary

Term	Meaning	Example
Scenario	An isolated sandbox where you test modifications without impacting production.	"Increase supplier A price by 10%"
Mutation	An individual modification within a scenario.	Change the "price" property from 100 to 110
KPI	A key indicator you track to evaluate impact.	Gross margin, Total cost, Average lead time
Simulation	A temporal execution that advances a scenario step by step.	Simulate 12 months of price variations
Solver	An algorithm that searches for the optimal configuration under constraints.	Minimize total cost by adjusting quantities
Portfolio	A group of scenarios to compare simultaneously.	Scenario A vs B vs C

Recommended paths

Links with other modules

Ontologie: scenarios apply to instances of your business model. Mutations virtually modify the properties of your entities.
Governance: applying a scenario to production can trigger an approval request if a policy is active.
Dashboard: dashboard KPIs can be compared between the reference scenario and your hypothetical scenarios.
Workflows: a workflow can create a scenario, run a simulation, and apply the result automatically.

Expected outcome

You can test hypotheses safely, compare impacts on your KPIs, and make data-driven decisions before applying changes in production.
