Predictive Analytics & Physics-Based Modeling

Combine machine learning, first-principles engineering, and physics-based modeling to characterize system behavior, improve process understanding, and enable more accurate, reliable operational decision-making.

Overview

Industrial systems are governed by complex physical, chemical, and operational relationships that evolve over time. While data-driven models provide powerful predictive capabilities, relying solely on historical data can sometimes limit reliability under changing operating conditions.

At nilmuda, we combine predictive analytics with physics-based, hybrid and reduced-order modeling approaches to develop solutions that are both data-informed and grounded in real-world engineering principles.

Our models leverage:

  • Historical and real-time operational data
  • First-principles engineering equations
  • Thermodynamics and reaction kinetics
  • Process dynamics and mass-energy balances
  • Machine learning and statistical forecasting techniques

This integrated approach enables more accurate predictions, deeper process understanding, and more robust decision support across industrial operations.

What We Do

Predictive Analytics

Develop advanced forecasting and predictive models for:

  • Process variables
  • Equipment behavior
  • Product quality
  • Energy consumption
  • Production demand
  • Supply chain and operational planning

Soft Sensors

Build virtual sensors that estimate difficult-to-measure variables using existing process data.

Soft sensors can help infer:

  • Product composition
  • Moisture content
  • Catalyst activity
  • Process efficiency
  • Quality parameters

without requiring additional physical instrumentation.

Physics-Based Modeling

Develop models grounded in engineering fundamentals, including:

  • Mass and energy balances
  • Heat transfer
  • Fluid dynamics
  • Reaction kinetics
  • Thermodynamic relationships

These models provide deeper process insight and improved interpretability.

Hybrid Models

Combine machine learning with first-principles engineering to create hybrid systems that balance:

  • Data-driven adaptability
  • Physical realism
  • Process interpretability
  • Improved predictive accuracy

Hybrid models are particularly valuable in environments where operational conditions frequently change or where process understanding is critical.

Reduced-Order Modeling

Develop computationally efficient reduced-order models (ROMs) that simplify complex physical systems while preserving the key dynamics and behaviors of the process.

Reduced-order models enable:

  • Faster simulations and predictions
  • Real-time optimization and control
  • Digital twin development
  • Process monitoring and scenario analysis
  • Improved computational efficiency for large-scale systems

These models are especially valuable in industrial environments where full-scale physics simulations may be too computationally expensive for real-time operational use.

 

Why Physics-Based Models Matter

Unlike purely statistical models, physics-based approaches incorporate the actual scientific behavior of industrial systems.

This provides several important advantages:

Improved Real-World Reliability

Models remain grounded in physical laws and engineering constraints, improving robustness under changing conditions.

Greater Precision & Interpretability

Predictions align with known process behavior, making results easier for engineers and operators to trust and validate.

Better Performance with Limited Data

Physics-informed approaches can still perform effectively even when historical data is incomplete or sparse.

Enhanced Process Understanding

Gain deeper insight into how variables interact across unit operations and process systems.

Supports Safer & More Stable Operations

Operational recommendations can incorporate physical and operational constraints to reduce risk.
