摘要
本文在螺旋模型的基础上提出了集成风险管理的软件项目开发过程模型,并运用实物期权理论框架解释和证明了该过程模型的优势。使用变波动率多期复合实物期权模型量化了螺旋开发过程模型中决策灵活性的价值,敏感性分析的结果表明,螺旋模型在风险水平越高的情况下价值越为明显。此外,变波动率复合实物期权的引入很好地刻画了螺旋模型风险驱动的特征,从而为软件项目开发过程中的动态序列决策提供了参考依据。
In this paper,a risk-driven software process model is created by integrating risk management into spiral process model.We adopt the time dependent volatilities compound real options model to describe the multiple phase structure and quantify the value of decision flexibility of this model.It is found that the spiral model excel other process model in uncertainty environment.The approach we present can help to understand and justify the spiral process in software project development.Besides,it is able to describe well the evolution of risk in the life cycle,and to provide references for the dynamic sequential decisions in different phases.
