# Network Optimization Modeler

## Overview

The Network Optimization Modeler is a strategic skill that optimizes distribution network design including facility locations, capacity allocation, and inventory positioning. It uses advanced modeling techniques to evaluate scenarios and recommend network configurations that minimize cost while meeting service requirements.

## Capabilities

- **Facility Location Optimization**: Determine optimal locations for distribution centers, fulfillment centers, and warehouses
- **Network Cost-to-Serve Modeling**: Model total cost-to-serve including transportation, inventory, and facility costs
- **Capacity Planning and Allocation**: Optimize capacity allocation across facilities and identify expansion needs
- **Scenario Analysis (Greenfield, Brownfield)**: Evaluate network redesign scenarios from scratch or building on existing infrastructure
- **Service Level Impact Assessment**: Analyze the service level implications of network design decisions
- **Carbon Footprint Modeling**: Incorporate sustainability metrics into network optimization decisions
- **Risk and Resilience Analysis**: Evaluate network resilience to disruptions and identify vulnerability points

## Tools and Libraries

- Network Optimization Solvers (Llamasoft, AIMMS)
- Simulation Tools
- GIS Libraries
- Optimization Libraries (Gurobi, CPLEX)

## Used By Processes

- Distribution Network Optimization
- Cross-Docking Operations
- Multi-Channel Fulfillment
