摘　　要：项目立项阶段由于评审时间有限,需要采用快速近似估算方法获取软件的规模以确定经费预算。本文提出基于专家经验和随机抽样的快速估算方法,将软件分解为不同的软件模块,由开发组织对不同的模块规模和成本进行预估并申报经费,估算人员利用专家经验以及对软件组件随机抽样进行详细度量,再利用快速近似估算方法估算出软件项目的整体规模,进而得到软件整体成本。实际应用表明,该方法是可行的。In the project-approval phase,due to constrained time for review,it needs quick and approximate estimate methods for obtaining software size to determine the budgets.This paper puts forward a quick estimation based on expert experience and random sampling,by which estimator first decomposes software into different software modules,the development organization pre-estimates size and cost of these different modules to declare funds,then estimator performs a detail measurement with expert experience and random sampling of software components,and estimates the total software project size by quick and approximates estimate method in order to get the total software cost.Application shows that this method is feasible.
