Modeling of software reusable component approach and its case study

A technique to reuse standardized software components is presented which features a component development process and component-oriented object layers together with validity demonstrated through applications. The approach is called the `standardized components and their composition approach.´ The technique, on the condition that the architecture of a product family is fixed for a certain period of time, has the following features: (1) development of software components and that of software products are performed independently, and (2) guidelines for software component analysis/design can be obtained using an object layer which is based on shared software resources (called objects). This software component development approach has been applied to three different cases: process monitoring and control software (mainly Fortran); distributed information processing system software (Cobol); and microcomputer embedded product control software (C and assembler). Excellent results have been obtained
