动车组研发是大型系统工程,对于研发周期及资源投入因干涉因素较多,很难精确预估。本文结合了NF公司长期的设计研发经验,围绕典型项目设计人员及工时投入与设计输出文件的匹配情况,兼顾偏差纠正,提出动车组全新研发项目的科学设计周期,指导类似项目的资源分配及计划制定,希望对相关行业提供一些经验借鉴。
EMU R & D is a large-scale systems engineering, for the research and development cycle and resource investment due to more interference factors, it is difficult to accurately predict. This paper combines NF company’s long-term design and development experience, focusing on the typical project designers and working hours and design output file matching, taking into account the deviation correction, put forward the EMU’s new R & D project of the scientific design cycle, and guide similar projects, resource allocation and planning Development, hoping to provide some experience in related industries.
