In this way the author studied what the basic modeling elements of cmms , such as entity , action , task and interaction , shows to be in the conceptual model of c4isr communication networks . a series of specifications of conceptual model were established in unified modeling language ( uml ) in this paper , which can be used in constructing the formal conceptual model . the author also discussed how to perform the validation and verification of the conceptual model 论文通过任务空间概念模型( cmms )在c ~ 4isr通信网络中的具体应用，研究了cmms基本建模元素?实体、动作、任务和交互在c ~ 4isr通信网络概念模型中的具体表现形式，制定了利用统一建模语言( uml )进行形式化概念建模时的一系列概念模型描述规范，探讨了概念模型的验证与校核方法。
