一个基于度量与场景集成的软件维护性预测模型A Software Maintainability Prediction Model Based on Integrated Measurement and Scenarios摘要：针对现有基于度量的软件维护性预测模型缺乏针对性和基于场景的预测模型不能够区分不同软件模块之间固有维护性的差异性的缺点，建立了基于度量和场景集成的软件可维护性预测模型，在基于场景的软件维护性预测过程中充分考虑软件不同模块设计特性的差异，将设计特性度量结果作为预测最终软件维护工作量的影响因子，这样保证了软件维护工作量预计结果更加准确，一个简单的案例验证了模型的有效性。Abstract: in view of the shortcomings of the existing software maintainability prediction model based on measurement with a lack of pertinence, and the prediction model based on scenarios which will not be able to distinguish between different software modules’ inherent maintainability, a software maintainability prediction model based on integrated measurement and scenarios has been established. In the process of software maintainability prediction based on the scenarios, the different software module design features are fully taken into consideration, taking the design characteristic measurement result as the impact factor to predict the final software maintenance workload. In this way it can ensure a more accurate expected result of the software maintenance workload. A simple case has demonstrated the effectiveness of the model.关键词：软件维护性，软件度量，软件维护场景，软件维护性预测Keywords: software maintainability, software measurement, software maintenance scenarios, software maintainability prediction软件维护性预测是在软件维护性需求、设计、实现等各个阶段对软件维护性水平进行预计和度量的活动，其目的是确认软件维护性水平是否达到设计要求、能否满足用户需求，并发现软件维护性设计的薄弱环节，指导软件设计人员进行软件维护性改进活动，以确保软件具有先天良好的维护性。本文针对现有基于度量和基于场景的软件维护性预测中存在的问题，研究了一种基于度量与场景集成的软件维护性预测模型。Software maintainability prediction is the activity to predict and measure the software maintainability level in the various stages of software maintainability requirement, design, and implementation. Its purpose is to confirm whether the software maintainability level can meet the design requirements and the demand of users, discover the weak link of software maintainability design, guide the software design personnel through software maintainability improvement activities, and ensure that the software has inherently
