摘要
首先通过对工作量估算理论的分析与总结,发现只有综合代码行技术、WBS法、三点技术法和COCOMO II维护型模型等多种方法,并对其进行改进,才能得到适合应用系统改造工作量精准估算的最终模型。然后,针对IPv6网络环境的某些特性,从运行环境配置和相关网络协议的代码行改造两个方面对应用系统改造进行研究,最终确定IPv6网络环境下的应用系统改造工作量估算模型,并基于C/S和B/S架构的工作量差异,得到B/S架构下的修正模型。最后,采用测试改造用例数据对模型的准确程度进行验证,并证明了此模型具有较高的精确性。
Firstly,through the analysis and summary of the effort estimation theory,we find that only by integrating a variety of methods such as the lines of code technology,WBS method,three-point technology and COCOMO II maintenance model,etc.,and improving them,can the final accurate effort estimation model suitable for applications transformation be obtained.Then,based on some features of IPv6 network environment,the applications transformation is studied from two aspects of the operating environment configuration and the transformation of lines of code of correlated network protocols,and the effort estimation model of applications transformation in IPv6 network environment is finalised;besides,based on the differences between the effort under C/S and B/S architecture,the correction model under the B/S structure is obtained.Finally,the data of test transformation use case are used to verify the accuracy of the model,and this proves that the model has high accuracy.
