Capacity vs demand analysis is the comparison of available manufacturing capability against required output over time to identify supply gaps or surplus - it is the primary diagnostic for balancing service level and utilization.

What Is Capacity vs demand analysis?

• Definition: Time-bucketed gap assessment between forecast demand load and effective factory capacity.
• Capacity Basis: Includes realistic uptime, yield-adjusted throughput, and constraint-tool limits.
• Demand Basis: Combines committed orders, forecast uncertainty, and mix-driven routing effects.
• Gap Outputs: Quantifies expected shortfall, headroom, or overload by period and product family.

Why Capacity vs demand analysis Matters

• Early Warning: Detects future bottlenecks before delivery commitments are missed.
• Pricing and Allocation: Supports policy decisions under sustained demand overhang.
• Investment Timing: Informs when to add tools, outsource, or rebalance product mix.
• Utilization Control: Highlights periods of underload that require start-rate adjustment.
• Strategic Alignment: Aligns sales commitments with operational feasibility.

How It Is Used in Practice

• Granular Modeling: Analyze by tool family, route segment, and product mix scenario.
• Mitigation Planning: Define actions for gaps, including capacity add, mix shift, and schedule changes.
• Review Cadence: Recompute with rolling forecasts and updated factory performance data.

Capacity vs demand analysis is a core planning control for fab balance - disciplined gap visibility enables proactive actions that protect both delivery reliability and capital efficiency.
