基于源代码的面向对象软件可维护性度量模型

摘要

Aiming at the outstanding problem which is difficult to measure the software maintainability at present time, based on detailedly expounding on the concept and connotation of software maintainability, guided by the ISO/IEC 9126, the metrics model of object-oriented software maintainability is built. The model includes four sub-identity models of maintainability and a colligation model to the sub-identity, the model can quantificationally figure out the software maintainability. Finally, the example verifies that the model is scientific and reasonable.%针对当前软件可维护性的度量难度大的突出问题,在详细阐述软件可维护性的概念和内涵的基础上,以ISO/IEC9126为指导,建立基于源代码的面向对象软件的可维护性度量模型.该模型主要包括可维护性的4个子特性模型和一个对子特性的综合模型,能够客观定量地计算出软件的可维护性水平.最后通过一个实例,验证该模型具有一定的科学性和合理性,在实际应用中有一定的指导意义.
