What Arena Does

Business Process Simulation

Few business decisions are straightforward. Changes in one area of your business impact other areas—often in ways not anticipated. Business process simulation software is an effective way to evaluate the full implications of business decisions before they are put into practice.

How It Works

Discrete Event Simulation

Discrete event simulation describes a process with a set of unique, specific events in time. These flexible, activity-based models can be effectively used to simulate almost any process. For 30 years, Arena has been the world’s leading discrete event simulation software.
