Abstract: In order to refine the specifications and processes on the overall design of armored vehicles，the main concepts concerned on the system architecture of armored vehicles，such as the vehicle architecture of five object levels，six design categories，four-layers Work-Breakdown criteria and assemblies trade-off methods，are proposed based on the design theories in Refs. \[9-12\].The V-mode workflow and the conceptual design process from needs to solutions are defined，and the concept of set-based design(SBD) is introduced into the overall design of armored vehicles.The polices of intergraded portfolio development management are summarized.

Key words: armoredvehicle, systemengineering, systemdesign, set-baseddesign
