FlowTime— Flow Analytics
Flow analytics and discrete-event simulation for operational systems
FlowTime is a simulation engine built in C#/.NET 9, designed to make operational system dynamics visible, comparable, and explorable. It models flows of work through queues, servers, and routing decisions — the same kind of dynamics found in warehouses, logistics networks, production lines, and software systems.
The engine supports discrete-time simulation with configurable time steps, multiple server disciplines (FIFO, priority, shortest-job-first), arrival distributions, and branching logic. Models can be parameterized and swept across scenarios to explore what-if questions: What happens if we add a second sorting line? What if peak arrivals double? What if processing time drops by 20%?
FlowTime grew out of performance engineering work at Biometria, where understanding flow dynamics through million-transaction-per-day systems was essential. The insight: many operational problems aren't code bugs or infrastructure issues — they're flow problems that only become visible through modeling and simulation.
The engine is also being explored as a Liminara integration pack, where simulation models and their results become provenance-tracked artifacts with full decision recording. FlowTime Integration pack →
