Discrete event simulation

What is FlexSim simulation software?

FlexSim is 3D simulation software that models, simulates, predicts, and visualizes systems in manufacturing, material handling, healthcare, warehousing, mining, logistics, etc. It is both powerful and user-friendly. FlexSim helps to optimize current and planned processes, identify and decrease waste, reduce cost, and increase revenue. At FlexSim Software Products our goal has been, and always will be, to create the best simulation software.

FlexSim simulation software means value.

FlexSim Software Products is different from other sim software developers in that we are entirely focused on providing value to you and your business. We listen attentively to customer needs and invest the vast majority of our time and resources into simulation software development instead of marketing and advertising—all so our software can provide maximum value to our customers. Our active user base and knowledgeable technical support staff is ready and willing to help you make the most of your simulation software experience. We know you want answers about your business process, and we want to help you find them.

Simulate. Analyze. Optimize. All with FlexSim.
