联邦开发过程中的校核、验证与确认(VV&A)

Verification,Validation and Accreditation during the Development of Fedration

对联邦的VV&A不仅能够使每一步的工作得到跟踪和衡量,还使每一步能够减少多余的工作量,巩固需要加强的工作,明确开发人员的角色和职责,从而使人力、时间、资金等资源得到更加有效率的利用,仿真的结果变得更加可预测和准确,在很大程度上减少了编程的风险。联邦成员描述了仿真模型的各对象类、交互类、相关的属性、参数等信息,而联邦是各联邦成员的有机集成,构成具有特定功能的仿真系统。因此,联邦成员的正确性是联邦正确性的前提,决定了仿真系统的成败。在VV&A的过程中,最好采用一些自动化工具以便于工作,同时要根据具体仿真系统的实际情况来确定VV&A所需要作的工作。

The effort of verification, validation, and accreditation of federation not only tracks and measures each step of the development, but also supports easier adoption, tailoring, and leveraging within each step, thus making more efficient use and easier deployment, better clarification of roles and responsibilities, and potentially more predictable and accurate results - all of which result in reduced program risk. The federates describe the object classes, interaction classes, and the attributes/parameters related to them. The federation is the organic integration of the federates which constructs the simulation system having special functions. Thus the validity of the federates is the premises of the validity of the federation, and ~is the key of the success of simulation system. During the process of validation, verification, accreditation, automated support tools should be adopted to reduce workloads, and which work should be done depends on the fact of the simulation system.
