According to the character of C4 ISR, the process model of capability⁃based requirement analysis is built based on studying on the method and flow of JCIDS system. Based on the acquirement, definition, analysis and implement of capabili⁃ty, four phases of background domain analysis, capability domain analysis, capability requirement analysis and capability scheme analysis is given and the activity in each phase is described. The process can guide the requirement analysis of C4 ISR.%借鉴了联合能力集成与分析系统的活动流程,根据指挥信息系统体系需求的特点,建立了基于能力的指挥信息系统体系需求分析的过程模型,围绕能力需求的获取、定义、分析与实现划分为4个子过程:背景分析、能力领域分析、能力需求分析、能力需求方案分析,并给出了4个阶段的基本活动和逻辑关系,为指挥信息系统体系需求的分析提供了规范的过程和活动指导。
