現在組込みシステムは大規模・複雑化しているためモデル中心設計などのソフトウェア開発手法の導入が積極的に進められている．組込みシステムではハードウェアとソフトウェアの連携を考慮したシステム開発が必要であり，ハードウェアの特性を取り込める開発手法が望まれている．本研究では，2 つの組込みソフトウェア開発事例を分析し，組込みシステムに適したソフトウェアアーキテクチャを提案する．このアーキテクチャは 3 層構造を持ち，ハードウェアを制御する層，アプリケーション機能を実現する層，それらを連絡する層に分けられる．また，提案するアーキテクチャを利用した開発プロセスを提案する．Because embedded systems are becoming large-scale and complex, software design methods, such as model-centered design, are brought in positively for embedded system developments. For embedded systems, the system development method in consideration of cooperation of hardware and software is required. We analyze two development cases of embedded software, and propose software architecture suitable for embedded systems. This architecture is divided into three layers: the layer which controls hardware, the layer which realizes application functions, and the layer which connects other layers. The development process using this architecture is also proposed.

機器組込みソフトウェア開発の生産性と品質を向上させるためのオブジェクト指向の開発方手法の提案とその有効性について述べる。組込みシステムにオブジェクト指向を適用する際には、要求からクラスの抽出方法、状態の抽出方法が開発者によりバラツキがある。要求から設計/実装の双方向のトレーサビリティの確保と動的分析、時間制約などのリアルタイム制御システム特有の問題を解決することで生産性と品質の確保を可能にした。本稿で提案する手法論は、1998年に発表した自律オブジェクト指向技術を更に研究を進めたものである。その中で特に本稿では分析手法と設計手法を中心に述べる。This paper proposes and evaluates an object-oriented development method to increase the productivity for the embedded software development. Extraction of classes and their states from the specification is the key to developing a good design for embedded software. The method introduces the bidirectional traceability between specification and design and program components, and solves peculiar problems to real-time control systems, including time constrains and resource contentions. As a result, the method allows us to improve the productivity and quality of the overall system development. The AOO (Autonomic OO) technology presented by the first author in 1998 has been enhanced to acquire the method explained in this paper, in which the techniques for analysis and design are highlighted.

There are various electrical appliances such as the cleaner, washing machines, and air conditioners in surroundings now. These products are operated by the embedded system and has been achieved the multifunction and high performance. The embedded system is electronic equipments composed by the microcomputer that provides a specific function. The function demanded for the embedded system becomes various, and the scale of the embedded software it keeps increasing in recent years. Model Driven Development is one of the development methods of embedded system. This development method is based on a model. This method enables to test at model phase without actual embedded system. In this study, the airship control system is designed with MDD. The PID control was modeled and built into the airship control system. Moreover, the performance of the airship control system was evaluated.

　View Summary

For the observation of the real world, many sensors are set to acquire information automatically and precisely. The application and utility of these sensors are clear, but reusability of them are limited. It is necessary to estimate openness of access to these sensors for utilizing these sensors effectively more. We suggest inquiry technique of the sensor information and technique to express data to perform the supply and demand matching of sensor data in the design of an open sensor network.

　View Summary

One of the important features of MDD is generating executable source codes from models. Existing approach for code generation is to embed action scripts into models. However such approach greatly increase the amount of model description by developers. Then, for the purpose of decreasing the description costs, this paper proposes a method that automatically generates statechart diagrams from UML structual model using design pattern.

　View Summary

In this paper, we propose a refactoring method to integrate similar rulesets in CSS descriptions. We try to improve the maintainability of CSS descriptions by applying the refactoring "Form Template Method" which is usually applied to the object-oriented language. We define a technique for measuring the similarity between two rulesets of CSS descriptions. The pair of rulesets with a higher similarity becomes a target of our refactoring method.

In this study, an airship control system was developed by MDD (Model Driven Development) method. In MDD method, models of the target system are constructed at first, and developing process is advanced using these models. The airship control system was modeled with MDD method, and "requirements model", "analysis model", and "design model" were made. Then the program of the airship autonomous flight system was coded on the basis of these models. Also the altitude/direction PID control system were embedded in the autonomous flight system. As a result, the system realizes accurate flight.

　View Summary

Because the program codes of the interactive Web applications tend to become complex, there is a problem of the decline in maintainability. The Double-Phase XSLT Structure has already been proposed as the technology to improve the maintainability of the business Web applications. In this paper, we verify whether this technology can be applied to the interactive Web applications. We applied the technology to a chess game described with JavaScript as an example of an interactive Web application. As a result, it was possible to manage the control flow and the process logic separately. We confirmed that the Double-Phase XSLT Structure technology was effective to the improvement in maintainability by considering the debugging method as maintenance of the interactive Web applications implemented by the technology.

There is a limitation in the Java object type that can be used for the SOAP message. The reason for the Java object type with the limitation is that it is not decided for the rule that shows with XML. Then, Automatic making of Serializer/Deserializer that Java object type converted into XML mutually, and the tool that enhanced the function of Axis to send and receive the data easily as SOAP message was developed.
