网构软件系统运行在动态开放的环境中，其行为很可能偏离其原始的需求规范。提出了一种基于交互的网构软件需求监控方法。首先根据网构软件系统与其环境之间的预期交互，将网构软件需求转化为基于环境的网构软件规范。然后对运行中的网构软件系统进行监控，根据网构软件系统与环境的实际交互情况收集网构软件系统行为，并将网构软件系统行为与规范进行比较。最后给出了监测报告。由于环境变化比需求变化更具有可预测性，我们的方法可以通过更新其环境来应对环境变化和网构软件系统演化。提出了一种基于交互的需求监控框架。并设计了相应的监控器。最后，通过一个案例分析说明了该方法的可行性.
The behavior of an Internetware system, which is running in a dymamic and open environment, is likely to deviate from its original requirements specification. In this paper, we propose an interaction based requirements monitoring approach for Internetware. Firstly the Internetware requirements are transformed into an environment based Internetware specification in terms of expected interactions between the Internetware system and its environment. Then we monitor the running Internetware system, collect the Internetware system behaviors in terms of actual interactions between the Internetware system and its environment, and compare the Internetware system behaviors with its specification. Finally a monitoring report is given. As environment change is more predictable than requirement change, our approach could handle environment changes and Internetware system evolution by updating its environment. A framework of the interaction based requirements monitoring is presented. Furthermore, a corresponding monitor is designed. At last, a case study is carried on to illustrate the feasibility of our approach.
