“…The conventional research is broadly divided into two methods, namely, a method in which an entire program is re-created in a top-down manner and a method in which reusable parts are extracted from legacy software as components to reconstruct a system in a bottom-up manner based on those components [2]. In both cases, the entire program had to be analyzed and relatively large-scale development had to be performed while domain experts and developers cooperated by using special-purpose analysis tools or knowledge bases.…”

SUMMARYIn this paper, the authors propose a method of evaluating the module structure of programs for embedded software in which maintainability has deteriorated due to repeated revisions and also describe a software improvement support tool that was developed based on the proposed method. The proposed evaluation method supports the improvement of a module structure that includes the exchange of data according to external variables, which is often used in embedded software, by applying the concepts of intermodule coupling and module cohesion from structured analysis. The support tool also has the following special features: (1) by displaying the exchange of data according to external variables as an interface with a higher-level function, it can display the "data flow between hierarchically related modules," which could not be displayed by conventional tools, (2) by using open source tools, it can be implemented with relatively few man-hours, and (3) it provides design guides and checklists that enable the software improvement method to be learned in a short period without regard to user expertise. From the results obtained when this tool was introduced in actual projects, it was apparent that the tool was effective in discovering and improving program structures that caused a deterioration of maintainability.

Software Reuse is a business solution to the increasing demand for software over supply. However there remains little investment in software reuse despite the availability of return-on-investment models to show the cost-benefits, organisational models for undertaking the task and the appropriate technology to do so. In addition investment in reuse which transcends commercial barriers is practically non-existent. This position paper argues that global Software Reuse in the 21st Century will not be fully exploited without breaking down the traditional customer-supplier relationship and adopting long-term business relationships and supply chain management.

“…The organization that has experience in developing software, but not yet used the software reuse concept, there exists extra cost to develop the reusable components from scratch to build and strengthen their reusable software reservoir [7,8] . The cost of developing the software from scratch can be saved by identifying and extracting the reusable components from already developed and existing software systems or legacy systems [9,10] . Tracz in [11] observed that for programmers to reuse software they must first find it useful.…”

Reuse repositories manager manages the reusable software components in different categories and needs to find the category of reusable software components. In this paper, we have used different pure and hybrid approaches to find the domain relevancy of the component to a particular domain. Probabilistic Latent Semantic Analysis (PLSA) approach, LSA, Singular Value Decomposition (SVD) technique, LSA Semi-Discrete Matrix Decomposition (SDD) technique and Naive Bayes Approach purely as well as hybrid, are evaluated to determine the Domain Relevancy of software components. It exploits the fact that Feature Vector codes can be seen as documents containing terms -the identifiers present in the components- and so text modeling methods that capture co-occurrence information in low-dimensional spaces can be used. The FV code representation of clusters or domains is used to find the domain-relevancy of the software components. PLSA has provided better results than LSA retrieval techniques in terms of Precision and Recall but its time complexity is too high. SVD Transformation with Naïve Bayes scheme has outperformed all other approaches and shows better results than the existing approach (LSA) being used by some open source code repositories e.g. Sourceforge. The DR-value determined is close to the manual analysis, used to be performed by the programmers/repository managers. Hence, the tool can also be utilized for the automatic categorization of software components and this kind of automation may improve the productivity and quality of software development
