Engineering Contradiction Analysis
1Productivity
If quantum computing is used to solve QUBO problems for logistics optimization, then productivity and resource allocation efficiency are improved, but device complexity increases
Solution Approach 1:
The system segments the logistics optimization problem into a QUBO (Quadratic Unconstrained Binary Optimization) format, dividing the complex supply chain problem into discrete binary variables that can be processed by quantum computers. This segmentation enables the quantum system to handle the optimization problem in manageable computational units.
Solution Approach 2:
A classical server computer acts as an intermediary between the user and the quantum computer. The server receives logistics data, formulates it as a QUBO problem, transfers it to the quantum computer, receives the solution, and converts it back to actionable logistics decisions. This intermediary layer shields users from quantum computing complexity while enabling access to quantum optimization power.
2Adaptability or versatility
If dynamic optimization of delivery routes is implemented, then resource allocation efficiency is improved, but computational complexity increases
Solution Approach 1:
The system implements dynamic optimization by continuously updating delivery routes and resource allocation based on real-time changes in supply and demand. The quantum-optimized solution enables the logistics system to adapt dynamically to changing conditions, adjusting routes and resource distribution in response to current market conditions rather than following fixed schedules.
