onstruction of "Soft system" by decomposing the large-scale system
To guarantee the flexibility of the computer system, the technology of making to parts of various software is researched. Ranges of the design and the production system, etc. which the system supports are huge, and securing the flexibility of the system becomes very difficult. It is an important theme to solve such a problem, and to facilitate the re-composition of a flexible system according to the use purpose. Then, the framework (frame and mechanism) by which a flexible system can be constructed is researched for the developer of a large-scale system.
