　View Summary

<p>Internets of Things (IoT) applications and services have spread and are rapidly being deployed in the information services of the healthcare and financial industries, etc. However, the previous paper suggested that the current IoT services were individually developed, therefore, the open platform and architecture for the above IoT services of the healthcare industries should be deemed necessary. An open healthcare platform is expected to promote and implement the digital IT applications for healthcare communities efficiently. In this paper, we suggest that the open platform for healthcare related IoT services will be proposed and verified by the research initiative named “Open Healthcare Platform 2030 – OHP2030”. In addition, the vision for the OHP2030 research initiative is expressed.</p>

Poster presentation

　View Summary

<p>To assure that a system is safe, several tasks must be performed, resulting in the compilation of several safety-related documents. It is important that all the information related to safety is developed and maintained consistently. Because of retirements and changes to different department, it is difficult for engineers to pass on their knowledge. To ensure consistency throughout a project lifecycle notwithstanding program-level changes, a method to express the relationship between the safety information described in different documents is needed. Moreover, to address not only specifications but also bases for design formulated by a designer, design knowledge is accumulated together. We aim to improve the understanding of the safety design. In this study, we add two rules to the D-Case in order to achieve three goals. To verify the effectiveness of our method, these rules were applied to a rocket system.</p>

Ontology for weather observation system

Oral presentation (general)

　View Summary

<p>Why do humans develop systems? The answer is clear: to realize system capabilities by utilizing these systems. Unless a system realizes the intended capability, it is useless, even if the system itself is perfect. Every system needs something to be realized. The problem is that we do not know how to deal with unexpected problems that prevent the realization of the system capability. Of course, many studies have been conducted on how to develop robust, fault tolerant systems, but there is no existing research on how to determine the system’s resilience in relation to its capability. The system capability can be realized by developing a resilient system. In this study, we developed a system ontology especially for a weather observation system. This ontology can describe the entire system by applying DODAF 2.0 and an enabler relationship. It allows us to determine all of the system entities and relationships. In addition, the ontology shows the system’s resilience by considering the realization of the system capability. This ontology was applied to a weather observation system to verify its effectiveness.</p>

Oral presentation (general)

　View Summary

<p>Since the year 2000, Enterprise Architecture has been the object of focus as a method for promoting an IT architecture that establishes consistency between corporate business and IT strategies, and it has been applied mostly in global corporations. On the other hand, with the recent progress in Mobile IT technology and Cloud computing, in the IT systems of global corporations, the shift from conventional on premise server-based IT systems to Cloud computing, such as Software as a Service (SaaS), Hybrid Cloud, and connected Mobile IT systems, has become more pronounced. In promoting Enterprise Architecture, EA based upon an approach compatible to the cutting-edge IT technologies of Mobile IT/Cloud computing will be required by global corporations. This paper elucidates key points for EA methods to respond to the cutting-edge IT technology that will be required in the future by conducting a comparative analysis of the support environments of Mobile IT elements and related Cloud computing technology in each EA framework currently used widely in many global corporations.</p>

Multi-stakeholder interactive simulation for federated satellite systems

Grogan Paul T., Golkar Alessandro, Shirasaka Seiko, De Weck Olivier L.

2014 IEEE Aerospace Conference, 

2014.03

, 

Oral presentation (general)

　View Summary

<p>Federated satellite systems (FSS) are a new class of space-based systems which emphasize a distributed architecture. New information exchanging functions among FSS members enable data transportation, storage, and processing as on-orbit services. As a system-of-systems, however there are significant technical and social barriers to designing a FSS. To mitigate these challenges, this paper develops a multi-stakeholder interactive simulation for use in future design activities. An FSS simulation interface is defined using the High Level Architecture to include orbital and surface assets and associated transmitters, receivers, and signals for communication. Sample simulators (federates) using World Wind and Orekit open source libraries are applied in a prototype simulation (federation). The application case studies a conceptual FSS using the International Space Station (ISS) as a service platform to serve Earth-observing customers in sun-synchronous orbits (SSO). Results identify emergent effects between FSS members including favorable ISS power conditions and potential service bottlenecks to serving SSO customers.</p>

<p>As satellite technology has been highly advanced, it has become difficult to assure dependability of satellite systems. Currently, dependability of satellite systems is mainly supported by various risk analysis and verification. However, sometimes it is not clear why such analysis and verification result are required for dependability of the satellite systems. In particular for development of micro satellites, due to time and cost constraints, management of risk analysis and verification has been done in ad-hoc manner. This paper presents a strategic development of a micro satellite using assurance cases. Assurance case is a documented body of evidence that provides a convincing and valid argument that a system is adequately dependable for a given application in a given environment. In Europe, assurance cases are widely used as regulation in safety- critical areas such as defense, avionics, rails, etc. In this paper, we take "Discharge and Charge system of Hodoyoshi-3 microsatellite" as an example. We conduct a writing experiment of assurance cases for the system and report how the assurance cases are used for quality assurance of the system.</p>

A new approach to component reuse in multi-software development project management by using an information-centric project model

Sakaedani Akihiro, Yasui Toshiyuki, Shirasaka Seiko, Maeno Takashi

14th International Dependency and Structure Modelling Conference, 

2012.09

　View Summary

<p>This paper evaluates the effects of component reuse by using a model that focuses on information transfer in software development projects. The cost models from earlier studies do not account for the difficulty of reuse, whereas the proposed information-centric model does consider the level of this difficulty. This paper has two main conclusions. First, component reuse does not always improve the productivity of a software development project. Second, component reuse is a valuable productivity tool if the following conditions are satisfied: (1) reuse results in simplification of project structures and (2) the level of difficulty of project elements is decreased from the reuse of components.</p>

　View Summary

<p>This chapter proposes application of framework of system design of a special zone for reconstruction of Fukushima Prefecture which suffered serious damages from the Great East Japan Earthquake, tsunami and nuclear accident at the Fukushima Daiichi Nuclear Power Plant. The framework of system design used in this chapter is called the Interactive Social Design Model (ISDM). The ISDM is useful for aggregating stakeholders' requirements and values through the process of the interactive and bottom-up communication with stakeholders, and derivation of the optimal policy in quantitative approach. In this chapter, the optimal policy designed by the ISDM for the purpose of reconstruction of Fuku-shima is compared with the existing system of the special zones for reconstruction, in which local governments which suffered from the earthquake can choose support measures from the catalogue of policy measures designed by the central government of Japan.</p>

Oral presentation (general)

　View Summary

<p>We have a strong demand to design computer control safety system because crew stats to stay the international space station continuously, but there is no design framework for spacecraft computer control safety system. In this paper, we propose the architecture framework for spacecraft computer control safety system to guide a safety systems engineer to design computer controlled safety system. This framework is based on the general safety design process and NASA's computer safety requirements. The architecture framework can be proposed in accordance with the coming new IEEE1471 standard. This architecture framework can cover all design processes which are mandatory to be conducted to design system safety architecture. From this result, we suppose that this architecture framework reaches at least mandatory level.</p>

A standard approach to find out multiple view points to describe an architecture of social systems

Oral presentation (general)

　View Summary

<p>According to the definition of "System" in various standards and handbooks, a systemdoes not necessarily have hardware-software components. This means that a social system without hardware-software elements is a kind of system. However, systems engineering techniques are not directly applied to define a solution of a non-technical social system's problems. In this paper, we propose a standard approach to find out multiple view points todescribe architecture, because the view points are one of the most important aspects of architectural design activities. And also we show one example that we applied our proposedapproach to non-technical social system: insurance system. It proved to be positive in applying architectural design technique with appropriate view points to design social system architecture.</p>
