F6计划第一阶段的VCDM工具概述

Overview of VCDM Tools in the System F6 Program Phase I

在F6计划的第一阶段,美国4家主流航空航天公司各自研发了基于计算机仿真模型的以价值为中心的设计方法(value centric design methodology,VCDM)分析工具,用于对单个航天器和分离模块航天器的风险调整后的净价值进行量化比较。论文阐述了以价值为中心的设计方法与传统以需求为中心的设计方法的区别,描述了VCDM的设计思想、价值模型;介绍了4家公司的VCDM工具及其应用情况,并对4个工具进行了比较。

During phase I of the system F6 program ,four major aerospace companies developed computer-based simulation models ,referred to as value centric design methodology （VCDM ） tools , and quantitatively compared the risk-adjusted ,net value of comparable monolithic and fractionated spacecraft .This paper identifies the fundamentally distinctive aspects of value-centric design ,which are contrasted with the requirements-centric status quo .The conception and the value model of the VCDM are introduced in detail .T he four VCDM tools and the application of the tools in phase I are summarized and compared .
