软件体系结构的可维护性评估研究

近年来,软件体系结构的可维护性得到了广泛的研究,其中可维护性的评估是关注焦点。然而,即使对某个软件体系结构的可维护性得出了定量的结果,也不能说明该软件体系结构的最优性(就可维护性而言)。通常情况下,软件构架师是根据自己的经验来判断评估结果。提出了一个基于场景的分析软件体系结构的最优可维护性的技术,该技术允许软件构架师从最优可维护性的角度来分析软件体系结构的可维护性。文章给出了该技术的一个应用例子。

Study on Assessing Software Architecture Maintainability

Recently the assessment of maintainability has received attention.However,even when one has a quantitative assessment of the maintainability of software architecture,one still does not have any indication of the optimality of the software architecture with respect to this quality attribute.Typically,the software architect is supposed to judge the assessment result based on his or her personal experience.In this paper we propose a technique for analyzing the optimal maintainability of a software architecture based on a specified scenario profile.This technique allows software architects to analyze the maintainability of their software architecture with respect to the optimal maintainability.The technique is illustrated and evaluated using industrial cases.
