Quantum-Inspired Computing Approaches for Complex Optimization Problems in Industrial Engineering

Abstract

Industrial engineering increasingly depends on solving large-scale optimization problems involving scheduling, routing, resource allocation, inventory control, energy management, and supply-chain coordination. Classical exact methods often become computationally expensive when problem size, uncertainty, and combinatorial complexity grow rapidly. Although practical quantum computers are still developing, quantum-inspired computing approaches have emerged as powerful alternatives that adapt principles from quantum mechanics to run on classical hardware. This paper investigates quantum-inspired computing approaches for complex optimization problems in industrial engineering. It examines methodologies including simulated annealing, tensor-network optimization, Ising formulations, quantum- inspired evolutionary algorithms, digital annealers, and hybrid classical-intelligent heuristics. Applications in production scheduling, facility layout, vehicle routing, maintenance planning, portfolio optimization, warehouse operations, and smart manufacturing are analyzed. Particular attention is given to solution quality, scalability, stochastic decision-making, real-time adaptability, and integration with Industry 4.0 data systems. Benefits include faster near-optimal solutions, improved operational efficiency, reduced energy consumption, and better responsiveness under uncertainty. Major challenges include formulation difficulty, parameter tuning, benchmarking inconsistency, interpretability, and transition barriers within traditional industrial workflows. A future roadmap is proposed involving hybrid quantum-classical ecosystems, AI- guided optimization engines, digital twins, and autonomous decision platforms. The paper concludes that quantum-inspired computing can deliver practical industrial value today by bridging the gap between conventional optimization and future quantum advantage, especially in environments where speed, flexibility, and complexity management are essential.

Quantum Computing–Enhanced Service Ecosystems for Industrial Manufacturing Simulation and Workflow Optimization

Erim Engin

The advent of quantum computing is redefining the computational landscape of industrial manufacturing, introducing new paradigms for simulation, optimization, and adaptive decision-making. This study investigates the integration of quantum computing–enhanced service ecosystems within industrial manufacturing frameworks, focusing on how quantum algorithms can accelerate workflow optimization, supply chain coordination, and process simulation in large-scale production environments. Traditional simulation and optimization techniques often struggle with the combinatorial complexity of modern manufacturing systems, leading to inefficiencies in resource allocation, scheduling, and predictive maintenance. The proposed framework leverages hybrid quantum–classical computation to simulate high-dimensional manufacturing workflows through quantum annealing, Quantum Approximate Optimization Algorithm (QAOA), and quantum-inspired reinforcement learning. These techniques enable more efficient exploration of multi-objective optimization spaces, facilitating near-real-time decision support and improved throughput under uncertain production conditions. The model also emphasizes the development of service-oriented architectures that integrate quantum computation with industrial Internet of Things (IIoT) infrastructures, digital twins, and cloud-based manufacturing services. Results from conceptual modeling and early simulation experiments suggest that quantum-enhanced service ecosystems outperform conventional digital twins and heuristic optimization methods in adaptability, precision, and energy efficiency. This convergence of quantum computing and industrial systems marks a shift toward next-generation intelligent manufacturing, capable of autonomous learning, dynamic reconfiguration, and sustainable production optimization.

Quantum-Inspired Optimization for Supply Chain Logistics and Inventory Management in E-commerce

Carlos Ramirez

E-commerce platforms face ever more complex dimensional SKU portfolios, demand volatility, returns, seasonality and cost pressures. Traditional optimization approaches (integer programming, heuristics, meta-heuristics) increasingly strain under scale, real-time demands and combinatorial explosion. Meanwhile, quantum-inspired optimization leveraging methods such as quantum annealing, coherent Ising machines, variational circuits and QUBO (Quadratic Unconstrained Binary Optimization) mapping offer near-term practical approaches to combinatorial logistics and inventory problems. This paper proposes a comprehensive framework for applying quantum-inspired optimization to e-commerce supply-chain logistics and inventory management: we provide an extended literature review of classical and quantum-inspired methods; we derive full mathematical formulations for logistics/inventory problems and map them into QUBO/quantum-inspired frameworks; we design a benchmarking/implementation methodology; we discuss industry architecture and deployment issues (data pipelines, latency, hybrid classical/quantum-inspired workflows, interpretability, cost benefit); we present use cases and discuss practical adoption in ecommerce. Our findings suggest that while fully fault-tolerant quantum computing remains some years away, quantum-inspired optimization can deliver meaningful improvements in logistics and inventory decisions today, particularly for large-SKU e-commerce, multi-warehouse networks and time-sensitive delivery.

Leverage Quantum Computing and Artificial Intelligence for Complex Problem Resolution: Innovative Optimization Framework

Suresh Kumar Pithani, Hebatullah Awwad, J Lethisia Nithiya +3 more

Optimization problems that are computationally intractable can be tackled with the help of AI and quantum computing. Standard optimization techniques are ill-equipped to deal with high-dimensional search spaces and non-linear constraints in domains such as logistics, finance, energy management, pharmaceutical research, and large-scale industrial scheduling. Using quantum computing with AI-driven learning, this research presents a hybrid optimization strategy that enhances the efficiency and accuracy of problem-solving. Adaptive optimization, parameter changes, and pattern discovery are all part of machine learning models, whereas quantum annealing and variational quantum eigen solvers simultaneously explore massive solution spaces. The proposed method uses quantum probabilistic computation and heuristic refining based on AI to reduce computational complexity and speed up the convergence of global optimums. While quantum computers optimize computationally expensively at the quantum-classical interface, deep learning models preprocess and extract features. Compared to metaheuristics, simulation-based performance analysis improves both the quality of solutions and the speed of convergence. The study demonstrated that AI frameworks boosted with quantum computing may solve combinatorial optimization problems and NP-hard problems. Using a computational paradigm that is both scalable and future-proof, this work reimagines optimization in the scientific, industrial, and engineering spheres.
