Pacific Consultants and JIJ Begin Proof of Concept for Mathematical Optimization in Social Infrastructure

Collaboration Between Pacific Consultants and JIJ

In a significant step towards addressing social infrastructure challenges, Pacific Consultants Co., Ltd. and JIJ Inc. have launched a proof of concept (PoC) aimed at validating mathematical optimization technologies for disaster management and infrastructure investment. The project commenced in July 2026 and harnesses JIJ's innovative JijZept platform.

The Rationale Behind the PoC

Japan faces urgent social issues, with frequent and severe natural disasters coupled with the rapid deterioration of existing infrastructure. In this context, it is critical to formulate plans that make the best use of limited resources. Such planning involves numerous variables and constraints, and the task of finding optimal solutions to these complex optimization problems is no small feat.

Mathematical optimization techniques are proving to be effective in tackling large-scale combinatorial optimization problems. Pacific Consultants intends to explore these techniques, potentially including quantum annealing, which is believed to offer superior solution-seeking capabilities compared to traditional methods. This application of quantum technology in the field of social infrastructure is viewed as one of the most promising opportunities for innovation.

By collaborating with Pacific Consultants’ extensive experience in disaster prevention and infrastructure management, and JIJ's expertise in cutting-edge mathematical optimization technologies, this PoC aims to provide practical approaches to these pressing social issues.

Overview of the PoC

The PoC leverages the JijZept platform, developed and provided by JIJ, which can handle both hybrid quantum and classical optimization methods. The main focus of this initiative is to optimize repair and investment plans for aging infrastructure. The project will construct and solve mathematical models to assess the applicability of optimization technology, as well as the accuracy and computational efficiency of its solutions.

JijZept is versatile, supporting various quantum and classical computing resources, including both gate and annealing methods. Insights gained from this PoC are anticipated to inform future applications in quantum computing technology.

Future Developments

Based on the insights derived from this PoC, the ultimate goal is to build a mathematical optimization computation framework capable of addressing a variety of social infrastructure issues, including traffic planning, logistics, and broader evacuation strategies. Both companies aim to lead the way in the societal implementation of quantum technology while contributing to the creation of sustainable social infrastructure.
