AAD Plant Layout Optimizer

Web-based facility layout tool using Systematic Layout Planning (SLP) adjacency ratings and a CRAFT-inspired pairwise swap optimization algorithm.

How It Works

1. Enter department names
2. Set pairwise adjacency ratings (A, E, I, O, U, X per SLP methodology)
3. Configure grid dimensions
4. The optimizer iteratively swaps department positions to maximize adjacency proximity score
5. Best layout is displayed as an interactive Plotly heatmap

Scoring

• Departments with high adjacency (A=4, E=3) placed close together earn higher scores
• Undesirable adjacency (X=-5) placed close reduces score
• Score = Σ (adjacency_rating / manhattan_distance) across all department pairs

Quick Start

pip install -r requirements.txt

Relevance

Directly applicable to factory layout planning for injection molding, stamping, and assembly plants — uses the same SLP methodology taught in industrial engineering programs.
