THE CONVICTION BEHIND EXA
We don’t wait for uncertainty to disappear.We engineer ways to succeed within it.
From the complexity of business to personal ambition. This is why EXA puts science to work.
The EXA philosophyTHE SCIENCE BEHIND EXA
The uncertainty of business.
The structure of science.
Business is complex. The way we approach it should be precise.
EXA explores the fundamental principles of business—and turns scientific methods into working systems.
01 / SCIENTIFIC METHODS
Mathematics for a changing world
Bayesian mathematics, optimization and reinforcement learning. Analyze changing conditions, compare possible choices and calibrate models through actual outcomes.
02 / CONNECTED KNOWLEDGE
Explore our philosophyKnowledge built on relationships
Ontology and knowledge graphs connect data with context. AI agents support understanding and execution on this foundation.
EXA Science EngineOmni+ · ExaWin+
Connections to understanding. Outcomes back to learning.

ERP data · Ontology data
Transactions recorded. Knowledge connected.
Transactions and actual results are recorded as ERP data and automatically structured as ontology data, capturing their objects and relationships. Operational records and their connected knowledge structure are prepared together.

THE PURPOSE OF OUR SCIENCE
For better decisions.
For solutions that achieve the goal.
OUR FOUNDATION

GROUNDS FOR CHOICE

No single theory or calculation is treated as the answer. We compare and evaluate in the context of the real situation.

WHAT WE AIM FOR
Good
enough.
Practical sufficiency
A solution that can be put into practice with the resources at hand—and is sufficient to achieve the goal.
HUMAN-IN-THE-LOOP PROCESS
The operational execution loop
In production, purchasing and scheduling, EXA proposes actionable alternatives that reflect operating conditions and constraints. When practitioners adjust and decide in context, the system immediately incorporates their judgment and adjustments to keep the workflow moving without interruption.

STRATEGIC DECISION SUPPORT
Strategic intelligence for leadership
EXA combines business theory with mathematical and scientific methods to examine risks and opportunities in the company’s actual data from multiple perspectives. Bayesian inference, ontology and reinforcement learning are applied to suit the problem, revealing outcomes and uncertainty across scenarios. Leadership gains in-depth analysis and a sound basis for setting strategic direction.
Analyze risks & opportunitiesCompare scenariosStrategic decisions
For better decisions. For solutions that achieve the goal.
EXA combines the theories and experience accumulated in business with mathematics and scientific methods. Rather than treating any single theory or calculation as the answer, we examine possible outcomes and uncertainty to establish grounds for choice within real-world constraints.
Our aim is Good enough — practical sufficiency.
A solution that can be put into practice with the time and resources at hand, and is sufficient to achieve the goal. People make the decisions and act, then feed the results back to refine the next choice.
BUSINESS SCIENCE IN PRACTICE
Real operating problems. Science put to work.
Bayesian methods and MCMC. Ontology and simulation. Reinforcement learning. EXA applies these methods to the problem at hand. Explore one operating example for each method. These three use cases illustrate just a part of EXA’s broad range of applications.
Choose a method. Explore an application.
BAYESIAN · MCMC
AN APPLICATION · On-time material delivery
Production is scheduled. Will the materials arrive on time?
A delivery record is more than a date. It reflects a supplier’s decisions, production capabilities and ways of working. EXA learns those distinct delivery characteristics from the company’s own transaction data. From the first purchase order, it brings on-time delivery probability and risk into view—while there is still time to protect the production schedule.
- 01
Learn how each supplier delivers
The same material can carry different delivery risks depending on its supplier. Actual transaction conditions and delivery outcomes update Bayesian models; MCMC helps assess the combined uncertainty. Delay risks hidden behind an average lead time become part of the decision.
- 02
Manage risk from the first purchase order
Assess on-time delivery probability alongside the buffer protecting production, highlighting orders that need attention. Update risk as supply conditions change. Management begins while there is time to act—not after a delay is confirmed.
- 03
Learn from the response and its outcome
Record staff interventions, supplier responses and actual receipts together. Distinguish deliveries kept on time through intervention from those achieved without it. The company’s experience of managing risk feeds back into future forecasts and action.
From reporting delays to managing risk before it disrupts production.
THE KNOWLEDGE BEHIND THE SYSTEM
Behind the technology,
principles you can explore.
EXA’s knowledge system is not an appendix to its software. It is the foundation for designing and validating it.
From scientific theory to algorithm design and practical use. Our documentation explains not only the results, but the principles that produce them.

BUILT FROM THE REAL WORLD

30
YEARS IN THE FIELD
Enterprise systems. Decades of hands-on business experience.
Every solution begins in the field.
A late material delivery disrupts production and puts commitments to customers at risk. Even one change in a system reaches across departments. Building enterprise systems has taught EXA the connections—and the consequences—behind everyday operations.
Our work is not to rephrase operational problems as technology buzzwords. It is to understand how work moves, recognize real constraints, and combine experience with business theory, mathematics and science to build solutions that work. This is how EXA creates software.
