A service business model method using ArchiMate has been proposed. However, there have been no reports on the application of AI systems to business models. In this paper, we present the results of applying the ArchiMate-based service business model method to an AI station attendant that takes over the duties of manned station attendants at unmanned stations.

In STEM education, attention is focused on the cycle of organizing real events, obtaining a real model, converting it into a mathematical model, and processing it mathematically to translate the mathematical results into real events. However, from an educational perspective, it is also necessary to emphasize the phase in which mathematical models take root as the basis of STEM education . In order to realize this phase, this paper will focus on using the body in a space with physical reality. The presenter proposes a ``hybrid experiment'' as a mathematics education method that links three experimental mathematics: experimental mathematics conducted using paper and pencil, experimental mathematics using blackboard and chalk, and experimental mathematics using mathematical software on a computer.

In order to analyze the comprehensive completeness of business processes, a defect prevention diagram that clarifies not only input-output but also accept conditions, resource conditions, decision conditions, and exception conditions has been proposed. However, issues in applying defect prevention diagrams have not been clarified. In this paper, we clarify the issues and effectiveness of the application of defect prevention diagrams by applying them to specific business processes.

System theories, including Soft Systems Methodology, have been proposed as methods to solve social issues in the past. However, the relationship between these methods and agile development methods, such as User Story and MVP Canvas, as well as Enterprise Architecture, has not been clarified.In this paper, we propose a method to integrate CATWOE, User Story, Service Scenario, MVP Canvas, and ArchiMate based on system theories. We also show an example of applying this method to a disaster information sharing system.

Requirements specification must describe not only functional requirements but also non-functional requirements. A Method for improving reliability by identifying input exceptions has been known. Previous methods for extracting non-functional requirements based on questions about functional requirements have also been proposed. However, it was not clear how to extract non-functional requirements based on the business processes that functional requirements automate.In this paper, we propose a method for extracting non-functional requirements based on the input acceptance conditions, resource conditions for executing business processes, and output judgment conditions of the business processes that functional requirements support, as well as their exceptions.
