NATO软件复用标准导论

软件复用包括开发可复用软件构件和基于可复用构件的软件开发两个生存周期。在这两个生存周期中,采用一个适当的标准以识别和开发可复用软件将大大促进软件复用的实践。为此,NATO(北大西洋公约组织)制定了一整套软件复用的指导性标准,以帮助NATO及其参与国和承包商的项目管理部门进行有效的软件复用。这套标准包括《可复用软件构件开发指南》、《可复用软件构件库管理指南》和《软件复用过程指南》三个文档,分别从软件生存周期的各个阶段对软件复用进行指导,以便最大限度地减少复用代价和增加复用收益。

软件复用技术的探讨

软件复用是指利用现有的软件成分(资源)来构造新的软件系统。通过软件复用,在应用系统开发中可以充分地利用已有的开发成果,消除了包括分析、设计、编码、测试等在内的许多重复劳动,从而提高了软件开发的效率,同时,通过复用高质量的已有开发成果,避免了重新开发可能引入的错误,从而提高了软件的质量。该文将对软件复用技术的基本概念及关键技术进行全面的介绍。     

可复用软件构件的表示和检索

一、引言软件复用已经融入软件工程研究的主流,被视为是使软件开发真正走上工程化和产业化道路的希望。人们在实践中认识到软件复用是一个涉及到技术、方法学、管理和文化等多个方面的复杂问题。除了日常隐含发生的对专业知识和经验的复用之外,最典型的复用活动表现为借鉴、理解、修改和集装各种不同抽象层次(从产品的概念、系统模型和规约到程序源码甚至目标码)、不同粒度(从系统构架、框架、类簇到代码片断)、不同形式(黑盒构造块、生成器、模板、设计模式等)的可复用软件构件来构造新系统和实现系统演化的过程。根据复用对象的不同,可以将复用划分为产品复用和过程复用两大类,产品和过程都被称为可复用软件构件。本文将只讨论产品复用。

The impact of software evolution and reuse on software quality

This paper presents a case study of a software project in the maintenance phase. The case study was based on a sample of modules, representing about 1.3 million lines of code, from a very large telecommunications system. Software quality models were developed to predict the number of faults expected from the coding through operations phases. Since modules from the prior release were often reused to develop a new release, one model incorporated reuse data as additional independent variables. We compare this model's performance to a similar model without reuse data.Software quality models often have product metrics as the only input data for predicting quality. There is an implicit assumption that all the modules have had a similar development history, so that product attributes are the primary drivers of different quality levels. Reuse of software as components and software evolution do not fit this assumption very well, and consequently, traditional models for such environments may not have adequate accuracy. Focusing on the software maintenance phase, this study demonstrated that reuse data can significantly improve the predictive accuracy of software quality models.

Component Specifications for Robotics Integration

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.

Building enterprise reuse program——A model-based approach

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

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.
