Software Function, Source Lines of Code, and Development Effort Prediction: A Software Science Validation

One of the most important problems faced by software developers and users is the prediction of the size of a programming system and its development effort. As an alternative to "size," one might deal with a measure of the "function" that the software is to perform. Albrecht [1] has developed a methodology to estimate the amount of the "function" the software is to perform, in terms of the data it is to use (absorb) and to generate (produce). The "function" is quantified as "function points," essentially, a weighted sum of the numbers of "inputs," "outputs,"master files," and "inquiries" provided to, or generated by, the software. This paper demonstrates the equivalence between Albrecht's external input/output data flow representative of a program (the "function points" metric) and Halstead's [2] "software science" or "software linguistics" model of a program as well as the "soft content" variation of Halstead's model suggested by Gaffney [7].     

基于插件平台的软件开发过程研究

面向对象的软件开发方法增强了代码的可重用性,但是设计出的软件还是一个整体,不能像硬件一样实现"即插即用"。为了实现软件的"即插即用",可以采用插件技术,软件由一个个的模块(DLL)组装而成,不需要集成各源代码或链接库进行编译与链接。需要新的功能组件时也是按规定开发,之后只进行组装软件就可以使用。以前使用过的功能组件可以稍加修改或直接用于以后的软件开发。这种方法增强了软件的可扩展性和可维护性,也为软件开发人员降低了软件开发的代码集成难度。本文研究结合农业部农业建设项目管理信息系统的设计,论述如何在插件体系环境中进行软件的开发和管理。     

A Quality-Enhancing Software Function Deployment Model

Software quality has become a topic of increasing importance during the past decade. the quality of software is primarily determined by the quality of the software development process. Even small improvements in the software development process can result in a significant improvement in software quality. the use of software metrics technologies to assess design quality is a key issue in the management of information systems.

Software Quality Function Deployment (SQFD) is a useful requirement-gathering tool, especially in communication with users and meeting user requirements. However, software quality cannot be reviewed in isolation. Without an assessment of the goals of a project, the efficiency of software function derived from customer requirements is meaningless.

This article proposes an enhanced software quality function deployment process of integrating Goal-Question-Metrics and Software Quality Function Deployment. A software development process with this model will enhance the quality of the software. A case study is also presented to illustrate the enhanced software quality function deployment process. the main contribution of this article is to help software developers produce higher-quality software that not only meets customer requirements, but also achieves the goals of the project.     

The determination of optimal software release times at different confidence levels with consideration of learning effects

As most software reliability models do not clearly explain the variance in the mean value function of cumulative software errors, they might not be effective in deducing the confidence interval regarding the mean value function. In such cases, software developers cannot estimate the possible risk variation in software reliability by using the randomness of the mean value function, thus reducing the decision‐making reliability when determining an optimal software release time. In this paper, the method of stochastic differential equations is used to build a software reliability model, which is validated based on practical data previously used in six published papers. Moreover, the estimation of the parameters of the proposed model, which can be defined as the autonomous error‐detected factor and the learning factor, is also illustrated, and the results of model validation empirically confirm that the proposed model is able to account for a fairly large portion of the variance of the mean value function. Additionally, the confidence intervals of the mean value function regarding software faults are employed to assist software developers in determining the optimal release times at different confidence levels. Finally, a numerical example is given to verify the effectiveness of the proposed model. Copyright © 2008 John Wiley & Sons, Ltd.
