Hybrid Quantum-Classical Algorithms for Real-Time Supply Chain Optimization

Abstract

Real-time optimization is one of the current hot challenges cutting across the present-day industries due to the complex nature of decisions about dynamic management inventories and their transportation concerning their relevant demand and traffic forecasts. For these reasons, traditional optimization fails most of the times since computation traditionally cannot accommodate large sets in real-time input. This paper outlines a hybrid quantum-classical framework that leans on the benefits of quantum algorithms in solving combinatorial problems and the strength of classical optimization for continuous variables. Mathematically, it models the supply chain by way of mathematical models such as MIP and multi-objective optimization formulation of transportation costs, inventory holding costs, and demand fulfillment constraints.

The proposed architecture unifies quantum systems, such as quantum annealers, to approach NP-hard problems like route optimization while classically refining the solutions and managing IoT devices and ERP system real-time data streams. The hybrid architecture is designed on an iterative loop of feedback cycles to ensure scalability and low latency together with adaptability to dynamic conditions in the supply chain. Results from experimental assessments indicate that a considerable improvement in computational performance, cost minimization, and responsiveness for the framework compares well with methods using traditional approaches.

It explores how hybrid quantum-classical algorithms hold the potential of redefining optimization in the realm of supply chain management and letting industries manage the decision-making processes in real time at such immense scales. It allows for a future vision of combining quantum computing into actual logistics and operational management processes.
