软件产品的应用日益广泛,软件研制过程中出现的问题也不断增多。随着业内的不断探索,逐渐发现软件重用(含过程重用和产品重用)是解决"软件危机"的有效手段之一。软件过程资产库将软件研制过程中积累的可重用过程和可重用产品在信息化平台中进行统一管理,便于项目层进行查询和使用,促进软件研制效率和软件产品质量的提高;从组织层来看,通过不断优化可重用过程并积累可重用产品,可以实施持续的软件过程改进,逐步提高软件研制能力成熟度,不断增强软件组织的竞争力。为了提升软件研制能力,研究并建立了软件过程资产库,结果表明软件过程资产库在提高软件研制能力方面具有显著作用。  相似文献

实施一个面向对象框架的方法   总被引:4,自引:2,他引:4  
周警伟  罗晓沛 《计算机仿真》2002,19(3):《计算机仿真》-2002年19卷3期-107-109.页-《计算机仿真》-2002年19卷3期-107-109.页
软件重用是在软件开发中避免重复劳动的解决方案,通过软件重用,可心提高软件开发的效率和质量。然而通常的一些重用技术如使用类库等仍然不能满足对重用的要求。一个面向对象的框架是针对某些特定领域的一些组件的整合,它从更高的层次和更大的规模来软件重用。它不仅重用了代码,而且重用了分析和设计,以求更好地提高效率和质量。该文主要从方法学的角度讨论如何实施一个面向对象的框架(Object-Oriented Framework,简称为OOF)的方法,同时介绍国内外在面向对象框架领域的一些研究和实践活动,并对如何加强相关领域的研究提出一些思路。  相似文献

传统软件开发模型存在开发效率不高,不能很好地支持软件重用等缺点。在多个大中型软件项目的实践基础上,提出了基于体系结构的软件开发模型(ABSD)。ABSD模型把整个基于体系结构的软件过程划分为体系结构需求、设计、文档化、复审、实现、演化等6个子过程,讨论了各个子过程所要完成的工作,给出了ABSD模型在劳动和社会保险领域的一个应用实例。实践表明,采用ABSD模型进行软件项目开发,具有结构清晰、易于理解、可移植性强、重用粒度大等优点。  相似文献

Building enterprise reuse program——A model-based approach   总被引:1,自引:0,他引:1  
Reuse is viewed as a realistically effective approach to solving software crisis. For an organization that wants to build a reuse program, technical and non-technical issues must be considered in parallel. In this paper, a model-based approach to building systematic reuse program is presented. Component-based reuse is currently a dominant approach to software reuse. In this approach, building the right reusable component model is the first important step. In order to achieve systematic reuse, a set of component models should be built from different perspectives. Each of these models will give a specific view of the components so as to satisfy different needs of different persons involved in the enterprise reuse program. There already exist some component models for reuse from technical perspectives. But less attention is paid to the reusable components from a non-technical view, especially fromthe view of process and management. In our approach, a reusable component model--FLP modelfor reusable component  相似文献

There already exist some component models for reuse from technical perspectives. But less attention is paid to the reusable components from a non-technical view, especially from the view of process and management. In our approach, a reusable component model—FLP model for reusable component—is introduced. This model describes components from three dimensions (Form, Level, and Presentation) and views components and their relationships from the perspective of process and management. It determines the sphere of reusable components, the time points of reusing components in the development process, and the needed means to present components in terms of the abstraction level, logic granularity and presentation media. Being the basis on which the management and technical decisions are made, our model will be used as the kernel model to initialize and normalize a systematic enterprise reuse program.  相似文献

A Component Model for Perspective Management of Enterprise Software Reuse   总被引:4,自引:0,他引:4  
This paper discusses that in order to achieve systematic reuse, the technical and non-technical issues must be considered in parallel, and a set of component models should be built from different perspectives. Each of these models gives a specific view of the components so as to satisfy different needs of different persons involved in the enterprise reuse program. Especially, we present a reusable component model – FLP model for reusable component, which describes components from three dimensions (form, level, and presentation) and views components and their relationships from the perspective of process and management. This model determines the sphere of reusable components, the time points of reusing components in the development process, and the needed means to present components in terms of the abstraction level, logic granularity and presentation media. It is the basis on which the management and technical decisions are made. It will be used as the kernel model to initialize and normalize a systematic enterprise reuse program. After the FLP model, the relationships among these different models are discussed. Furthermore, the usage of these models to facilitate the perspective management of enterprise software reuse is discussed.  相似文献

Software reusability is widely believed to be a key to help overcome the ongoing software crisis by improving software productivity and quality. New computer technology and the demands of an advancing society require new and more complicated software. It is unrealistic to expect that every software system can be developed solely reusing existing software; however, software reusability has proven to be a way of enhancing software productivity and quality in different organizations. It is also believed that reuse of code segments alone does not significantly reduce software development effort.By creating reuse support information while software is being developed (when the software is best known to software developers), the reuse effort for both software development and maintenance can be potentially reduced.In this paper, five types of RSI are presented: Semantic Web, Horizontal Web, Vertical Web, Syntactic Web, and Alternative Web. We collectively call these five webs a Quintet Web. The Semantic Web enables software developers to locate a software segment. The Horizontal Web provides a means to reuse a block of soflware along with other types of software from other phases of a development process. The inter-phase integration of software can be performed through this Web. The Vertical Web identifies the vertical relationship of a software block to its operational environment. The Syntactic Web locates all statements in which a variable is used. The Alternative Web provides alternative software blocks that perform an identical operation.A prototype of the Quintet Web is presented.  相似文献

Component Specifications for Robotics Integration   总被引:1,自引:1,他引:0  
Robotics researchers have been unable to capitalize easily on existing software components to speed up their development efforts and maximize their system's capabilities. A component-based approach for building the software for robotics systems can provide reuse and sharing abilities to the research community. The software engineering community has been studying reuse techniques for three decades. We present several results from those efforts that are applicable to the robotics software integration problem. We describe how to specify a software component so that a potential user may understand its capabilities and facilitate its application to his or her system. At the National Institute of Standards and Technology, we have developed a three-stage, component-specification approach. We illustrate this approach for a component that is relevant to robotics.  相似文献
