Data-Driven Simulation for Evaluating Profitability of PaaS Businesses in the Growth Phase
FY2023–2024
This study develops and validates a data-driven simulation method to explore product supply strategies that balance profitability and resource efficiency (environmental performance) in the growth phase of PaaS businesses. Using a used-PC rental business as a case, it reconstructs user decision-making and product circulation in detail, compares 405 strategy scenarios, and identifies effective strategies that enhance profitability and utilization. The results demonstrate the potential of this method as a general evaluation tool to support the sustainable growth of PaaS models.

Environmental Impact Assessment of Combined Clothing Ownership and Sharing Based on Consumer Analysis
FY2023–2024
This study evaluates the environmental impact of combining clothing ownership and sharing using Life Cycle Assessment (LCA), and analyzes the relationship with consumer behavior and preferences. Results revealed that for many users, environmental impact increased, indicating that sharing does not necessarily reduce ownership. However, some users successfully reduced their environmental impact by lowering ownership, highlighting the importance of identifying target users and designing appropriate services.

Verification of the applicability of a Digital Court mechanism for decentralized autonomous organizations
2021-2023
This study aims to resolve the oracle problem within decentralized autonomous organizations using an algorithm called Digital Court. To solve the issue of 'low voter turnout,' which is a characteristic challenge of decentralized autonomous organizations, we have devised an algorithm that extends the existing Digital Court mechanism by incorporating a delegated voting system.

Design for Sustainable Circular Economy Based Future Society
Co-Investigator, 2023-2026
To realize a circular economy, it is crucial to not only reduce environmental burden but also establish economic rationality among the ecosystem's stakeholders. In this course, we will focus on modeling the entire ecosystem and use simulations to analyze stakeholder relationships. We will identify factors that hinder economic rationality and conduct research to address these challenges.

Development of simulation for environmental and economic evaluation of digital technology in Product-Service Systems
Principal Investigator, 2023-2026
In recent years, 'Product-Service Systems (PSS),' where manufacturers offer product functionalities as services, have gained traction as a strategy to concurrently mitigate environmental impacts and boost economic growth. Leveraging digital technologies, such as the Internet of Things (IoT), is critical to maximizing the environmental and economic advantages of PSS. In this study, we develop a simulation that assesses the environmental and economic impacts of integrating digital technology during the PSS design phase.

Social Implementation of an Urban Circular Economy Model through a Soft System Centered on Businesses and Tokyo Residents
Co-Investigator, 2025-2027
Leveraging Tokyo's dense economic environment, this project aims to promote the distribution of ethical products and services that are environmentally friendly, economically viable, and socially responsible. To support sustainable choices by citizens and businesses, it will develop and test objective and fair evaluation indicators for circular economy (CE) initiatives. These indicators will be integrated with concrete business models and used to create a framework that also contributes to enhancing corporate value.

Study on the Design of Transition Scenarios for the Realization of Circular Economy Business Models
Co-Investigator, 2025-2028
This study aims to develop scenario design methods for circular economy (CE) businesses, focusing on home appliances, to shift away from mass production and consumption. Beyond technological development, it emphasizes the importance of institutional design and business models that meet consumer values. By integrating simulation models and consumer behavior experiments, the study evaluates and compares the environmental and economic impacts of CE scenarios, establishing a framework for effective environmental policymaking.
