Capacity Constraint Analyzer

Overview

The Capacity Constraint Analyzer provides production and supply chain capacity analysis using Theory of Constraints (TOC) principles. It identifies bottlenecks, models capacity exploitation strategies, and supports capacity investment decisions.

Capabilities

• Capacity Utilization Calculation: Resource utilization analysis
• Bottleneck Identification: Constraint and limiting factor detection
• Constraint Exploitation Strategies: TOC-based improvement approaches
• Capacity Adjustment Modeling: Expansion and contraction scenarios
• Lead Time Impact Analysis: Capacity effects on delivery performance
• Rough-Cut Capacity Planning: Aggregate capacity assessment
• Finite Capacity Scheduling Support: Detailed scheduling inputs
• Capacity Investment Analysis: CapEx decision support
