舰船装备软件维护成本估算研究

Maintenance Cost Estimation Method for Vessel Equipment Software

科学估算软件维护成本对确定舰船装备软件购置价格非常关键。分析软件维护成本的影响因素,建立维护成本估算指标体系,基于COCOMO的基本模型,对舰船装备软件的五个规模度因子进行合理赋值并利用收集到的舰船装备软件维护工作量数据,建立了舰船装备软件维护成本估算模型。

Estimating maintenance cost scientifically is very critical to price equipment software. Firstly, this paper studies characteristics which influence equipment software maintenance cost. Then, based on the basic model of COCOMO, we evaluate the five scale factors and modify the model using the experimental data, thus to put forward the maintenance cost estimation model for vessel equipment software.
