Modeling, Digital Twins, & Control Towers

Modern logistics depends on insight, speed, and coordination. Modeling, simulation, and digital twin solutions provide organizations the intelligence to design smarter networks and manage them in real time. with a powerful way to make smarter, lower-risk decisions before acting in the real world. Offline modeling allows companies to test new network designs, sourcing strategies, or policy changes without disrupting operations. Simulation extends that value by capturing variability—like demand shifts, transport delays, or equipment downtime—to reveal system behavior under stress and identify bottlenecks or resilience gaps. Digital twins take it further by maintaining a continuously synchronized, data-driven replica of the end-to-end supply chain, enabling ongoing scenario analysis, performance monitoring, and predictive optimization. Together, these tools empower teams to evaluate “what-if” scenarios, quantify trade-offs in cost, service, and sustainability, and adapt strategies dynamically, turning the supply chain into a continuously improving, decision-intelligent system.

SCT provides independent services leveraging these tools, but recommends embracing them as a holistic suite of products – though radically different in design – that allow you to continuously evaluate supply chain performance and risk management needs for overall supply chain excellence.  When integrated, these tools form a continuous improvement loop—design, simulate, predict, and act—that transforms transportation from a cost center into a source of competitive advantage. Organizations adopting this ecosystem often achieve 10–30% lower logistics costs, 20–40% faster response to disruptions, and measurable gains in service reliability and resilience.

Solutions Overview 

Transportation modeling provides a strategic foundation for network design and optimization. By simulating different routing, mode, and capacity scenarios, companies can evaluate cost, service, and sustainability trade-offs before making real-world changes. Modern modeling tools leverage in-memory computing to perform rapid what-if analyses, enabling teams to test hundreds of scenarios in seconds—such as rate changes, carrier shifts, or demand fluctuations. The result is faster, data-driven decisions that reduce costs, improve service levels, and increase network agility.

LMS focus on workforce productivity inside the warehouse, Labor Management Systems track labor standards, productivity, and workforce scheduling. Advanced solutions offer enhanced employee engagement capabilities.

A network modeling tool helps optimize inventory flows, transportation costs, and facility placement by providing a virtual environment to analyze the supply chain holistically and test alternative scenarios before implementing changes.  Network modeling

  • Simulates how stock moves between suppliers, plants, distribution centers, and customers, revealing bottlenecks, overstock, or stockouts. This allows planners to identify optimal inventory levels, safety stock positions, and replenishment strategies that minimize holding costs while maintaining service levels.
  • Models shipping routes, modes, and frequency, helping to evaluate trade-offs between cost, speed, and reliability. By comparing different routing strategies or consolidating shipments, organizations can reduce freight expenses and improve overall network efficiency.
  • Network modeling evaluates the impact of opening, closing, or relocating warehouses, plants, or distribution centers. It calculates service coverage, lead times, and cost implications for each configuration, helping companies select facility locations that balance proximity to customers, operational efficiency, and cost-effectiveness.

By integrating these analyses, network optimization tools provide a holistic, data-driven blueprint that aligns inventory positioning, transport strategies, and facility locations to minimize costs, improve service, and enhance overall supply chain efficiency.

A digital twin of a supply chain is a dynamic, virtual replica of the end-to-end network—including suppliers, production sites, warehouses, transportation flows, inventory, and customer demand—that mirrors how the physical supply chain operates. It integrates data from multiple systems (such as ERP, WMS, TMS, and IoT sources) to provide a continuously updated view of performance, constraints, and interdependencies.

This digital representation allows organizations to simulate scenarios, test decisions before execution, and predict the outcomes of disruptions or strategy changes. Unlike static models, a digital twin continuously learns and adapts as new data comes in, enabling proactive optimization of cost, service, risk, and sustainability across the entire supply chain ecosystem.  Its primary purpose is to understand how the supply chain behaves under different conditions and to forecast outcomes before making changes in the real world.

A supply chain control tower is an operational visibility and decision management platform. It aggregates data from multiple sources to provide a single, real-time view of supply chain events, performance, and exceptions. Its focus is on monitoring, coordination, and execution, enabling teams to detect issues, collaborate across functions, and take corrective action quickly.

In essence, the control tower helps see and respond to what’s happening now, while the digital twin helps simulate and optimize what could happen next. When integrated, they create a closed-loop system—where insights from the digital twin feed proactive decisions through the control tower, and live operational data from the control tower continuously refines the twin.

The Journey to Excellence

SCT works with client to empower their organization to continuously calibrate supply chain strategy and respond effectively to disruptions by focusing on the critical elements of this toolset and aligning cross-functional collaboration for optimal value throughout the progression.  Critical elements of this journey include:

  • Establish integrated visibility and data foundations – Ensure your enterprise systems, IoT devices, and external partner data feed into a centralized platform. High-quality, timely data is the backbone of simulations, digital twins, and control tower monitoring. Standardize definitions, metrics, and reporting so insights are consistent across modeling and execution tools.
  • Build analytical and modeling capabilities – Develop expertise in transportation modeling, warehouse simulation, network optimization, and digital twins. Encourage cross-functional teams to experiment with scenario analysis and “what-if” simulations to understand how changes in demand, supply, or network configuration impact cost, service, and risk.
  • Integrate planning and execution through a control tower – Use a supply chain control tower to continuously monitor operations and exceptions, providing real-time feedback to planning models and digital twins. This closed-loop system allows simulations to be informed by live data and enables faster, coordinated responses to disruptions.
  • Embed scenario-based decision-making in strategy – Adopt a culture where strategy calibration is driven by scenario outcomes, not just historical performance. Use network optimization and simulations to test potential strategies (e.g., adding facilities, shifting inventory, or changing transportation modes) and evaluate the trade-offs before implementing changes.
  • Continuously learn and refine – Regularly validate your models, digital twin outputs, and control tower alerts against real-world results. Update assumptions, parameters, and strategies based on what works and what doesn’t. Over time, this creates a dynamic, adaptive system capable of both proactive planning and rapid response.

  • Centralize data sources: Connect ERP, WMS, TMS, IoT sensors, and external partner systems to a unified platform.
  • Standardize metrics and definitions: Align KPIs, units of measure, and reporting formats across all tools.
  • Ensure data quality: Implement validation, cleansing, and automated update processes to support accurate modeling and monitoring.
