【摘要】：COSMIC方法作为当今主流的功能规模度量方法之一,不仅应用于商业应用软件的度量,还可应用于实时控制系统和多层系统的规模度量。该方法适用于软件项目开发的各个阶段,使用软件用户容易理解的术语,操作简单,无须软件设计专业知识,受到越来越多的软件公司的青睐和推崇。然而,COSMIC官方给出的度量手册仅仅罗列出度量时可遵循的原则和规则,并未给出清晰的度量流程,虽然有不少学者对COSMIC方法进行过一定的改进,但是仍未摆脱主观臆断带来的度量不一致。针对这些现状,本文在遵循COSMIC原则和规则的基础上,使用计算机工具替代部分人工度量操作,提出了一种半自动化COSMIC方法。本文主要工作:1.介绍了COSMIC方法的基本情况、两种软件模型和三个度量阶段。指出了COSMIC方法在实践中存在的困难,并给出了产生困难的原因分析。2.介绍了两种基于COSMIC方法改良的实施方法。指出并分析了这些改良的方法在实践中存在的困难及原因。3.在COSMIC及其他改良的方法原则基础上,修改并完善了一系列规则,引入计算机工具替代部分人工操作,提出一种半自动化COSMIC方法。4.运用本文方法对两个典型案例进行度量,分步骤展示度量过程。制定实验方案,选取4个案例,分别使用COSMIC方法和本文方法实施度量,并将结果进行比对分析,得出实验结论,验证了半自动化COSMIC方法在实践中的可行性。最后,本文分析了方法未解决的问题,对一些特殊情况展开说明,并对下一步的研究方向进行了展望。
[Abstract]:As one of the main functional scale measurement methods, the COSMIC method is not only applied to the measurement of commercial application software, but also to the scale measurement of real-time control system and multi-layer system. This method is suitable for every stage of software project development. It is easy to operate and needs no professional knowledge of software design, which is easy to understand by software users, and is favored and respected by more and more software companies. However, the official measurement manual given by COSMIC only lists the principles and rules that can be followed when measuring, and does not give a clear measurement process, although many scholars have improved the COSMIC method to some extent. But still not free from subjective assumptions brought about by the measurement is inconsistent. In this paper, based on the principles and rules of COSMIC, a semi-automatic COSMIC method is proposed by replacing some manual metric operations with computer tools. The main work of this paper is 1: 1. This paper introduces the basic situation of COSMIC method, two software models and three measurement stages. The difficulties of COSMIC method in practice are pointed out, and the reasons for the difficulties are analyzed. 2. Two improved methods based on COSMIC method are introduced. The difficulties and causes of these improved methods in practice are pointed out and analyzed. Based on the principles of COSMIC and other improved methods, a series of rules are modified and perfected, and a semi-automatic COSMIC method .4is put forward by introducing computer tools instead of some manual operations. This paper uses the method to measure two typical cases and shows the measurement process step by step. The experimental scheme was established and four cases were selected to implement measurement using COSMIC method and this method respectively. The results were compared and analyzed and the experimental results were obtained. The feasibility of semi-automatic COSMIC method in practice was verified. Finally, this paper analyzes the unsolved problems of the method, explains some special cases, and looks forward to the future research direction.
