# RippleFlo > Critical manufacturing planning powered by discrete event simulation (DES). RippleFlo simulates what will happen across your factory — batch campaigns, CNC queues, hold times, and release windows — before a schedule change hits the shop floor. RippleFlo is manufacturing simulation software for teams who need ripple tracing, what-if scenarios, and audit-grade replay beyond what ERP and APS can model. ## Product - **Discrete Event Simulation (DES) engine**: Event-by-event factory digital twin with queues, buffers, failures, and variability - **Ripple tracing**: See how one delay propagates to every order, batch, lot, and release window - **Pre-commit blast preview**: Preview schedule impact before publishing changes - **Chaos mode**: Stress-test breakdowns, material delays, and demand surges in software - **Audit-grade replay**: Deterministic re-run of historical scenarios for QA and compliance - **Factory Designer & Production Planner**: Model lines, routings, alternates, and scheduling rules - **War Room**: Real-time visibility into at-risk commitments ## Industries - Pharma & Biotech — batch release, API synthesis, hold times, fill-finish, campaign overlap - Aerospace & Defense — program milestones, NDT queues, qualified alternate routing - Process Manufacturing — shared reactors, distillation, campaign scheduling - Discrete Manufacturing — CNC job shops, per-order ripple tracing, machine downtime - Medical Devices — sterilization holds, cleanroom assembly, validation-ready traceability - Critical Manufacturing — regulated environments, contractual delivery, compliance replay ## Keywords discrete event simulation, DES manufacturing, manufacturing simulation software, factory planning software, production scheduling software, ripple effect manufacturing, schedule ripple tracing, manufacturing digital twin, APS alternative, ERP scheduling limitations, critical manufacturing planning, batch release simulation, pharma batch scheduling, aerospace production planning, CNC job shop scheduling, medical device manufacturing software, what-if manufacturing simulation, bottleneck analysis, MTBF MTTR simulation, audit-grade manufacturing replay ## Pages - [Home — Pharma & critical manufacturing](https://www.rippleflo.com/) - [Aerospace & Defense](https://www.rippleflo.com/industries/aerospace) - [Process Manufacturing](https://www.rippleflo.com/industries/process) - [Discrete Manufacturing](https://www.rippleflo.com/industries/discrete) - [Medical Devices](https://www.rippleflo.com/industries/medical) - [Critical Manufacturing](https://www.rippleflo.com/industries/critical) ## Demo app - [RippleFlo demo application](https://app.rippleflo.com) ## Contact - Email: contactus@rippleflo.com - Book a demo: https://www.rippleflo.com/#contact ## Optional Full sitemap: https://www.rippleflo.com/sitemap.xml
