# 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
