当设计方案的系统要求和系统的初步设计不断改变时,为了快速、准确和连续地选择评定这类竞争的设计方案,产生出了一种独特的成本模型,并已成功地用于诸如航天通信、导航、作战实用性和弹道导弹防御这样的系统研究。本文阐述了如何使用成本模型改进和(或)优化承包商的地位。这个成本模型利用由重量-复杂性关系组成的输入数据,来估算经常设计成本与经常研制成本以及第一个单位成本。对于建立和维护整个航天系统的各个成本参数的估算,本文也推导了计算方法。此外,本文中还讨论了在微型电路、设备完备因子和可靠性评估方面,成本模型应补充的工作。
When the system requirements of the design and the initial design of the system are constantly changing, a unique cost model has emerged for the rapid, accurate and continuous selection of such competing designs and has been successfully used in applications such as aerospace communications , Navigation, practical combat effectiveness and ballistic missile defense systems research. This article explains how to use cost models to improve and / or optimize contractor status. This cost model uses input data consisting of weight-complexity relationships to estimate recurring design costs and recurring development costs and the first unit cost. This article also deduces the calculation method for the estimation of various cost parameters for establishing and maintaining the entire space system. In addition, this article also discusses the work that should be supplemented with cost models in microcircuits, equipment completion factors, and reliability assessment.
