摘　　要：对需求任务、需求活动、需求工程过程以及需求工程过程系统进行形式化定义.用信息熵对需求任务演化进行度量,用联合熵对需求活动、需求工程过程以及需求工程过程系统演化进行度量.从需求工程过程的角度,用条件-事件网对需求工程过程的迭代、反馈进行微观演化建模.从系统工程的角度,用耗散结构理论对整个软件需求工程过程系统进行宏观演化建模.Requirements tasks, requirements activities, requirements engineering processes and requirements engineering processes system are formally defined. Requirements tasks are measured with information entropy. Requirements activities, requirements engineering processes and requirements engineering processes system are measured with joint entropy. From point of view of requirements engineering processes, microcosmic evolution of iteration and feedback of the requirements engineering processes are modeled with condition-event nets. From point of view of system engineering, macro evolution of the whole software requirements engineering processes system is modeled with dissipative structure theory.
