Are there any prescriptive analytics tools that integrate with planning systems and handle scenario simulation?

Yes. There are several prescriptive analytics tools that integrate with planning systems and support scenario simulation / what-if analysis. Common options include:

• Anaplan – Strong for connected planning, scenario modeling, and enterprise-wide forecast/simulation workflows.
• IBM Planning Analytics – Good for planning, budgeting, forecasting, and multidimensional scenario analysis.
• Workday Adaptive Planning – Offers planning and scenario analysis with integrations into finance and operational systems.
• SAP Analytics Cloud / SAP Integrated Business Planning (IBP) – Useful for supply chain and enterprise planning with scenario simulation.
• Oracle Cloud EPM / Oracle SCM Planning – Supports planning plus what-if scenarios and optimization in Oracle ecosystems.
• Kinaxis RapidResponse – Especially strong for supply chain planning, rapid scenario simulation, and response planning.
• o9 Solutions – Known for AI-driven planning, scenario modeling, and optimization across supply chain and commercial planning.
• Blue Yonder – Strong in supply chain planning, forecasting, and scenario-based decision support.

If you want, I can also help you narrow this down by:

1. industry (finance, supply chain, retail, manufacturing, etc.),
2. planning system you already use, or
3. whether you need optimization vs. just simulation/what-if analysis.
