| Research Abstract |
There are 2 phases in the development process of high reliable softwares.
1. a phase of gaining formal specifications
2. a phase of automatic transformation from specifications to programs
About 2.. there are rigorous methods using mathematical specifications and a kind of programs transformation methods for improving execution efficiency. However their objects still remain toy programs. There is scarcely any research about 1.
On the other hand, reuse of software is a key of efficiency of software development. For reuse in high abstract level, it need to retrieve flexibly specifications stored in the parts database which is similar to a given specification.
So, we have made the following researches. First of all, as research of gaining formal specifications, we research about software reuse based on similarity of algebraic specifications. We propose a reuse model based on specification, define similarity of algebraic specification and propose a method of retrieving specification based on similarity. Moreover, we propose a method of abstraction of difference of specifications.
As research on automatic transformation from specifications to programs, we propose a method of reuse program corresponded to specifications and implement its prototype. We study on patterns of correspondence between specifications and programs and made research on a method of program generation using their patterns. As research on software parts, we made a method of abstraction of program parts and application of program patterns.
Term Writing Systems for efficient verification of algebraic specifications and repository based on fine grain software parts are investigated as related work.
