虚拟现实技术为产品开发带来了全新的人机界面和强大的功能,虚拟环境将虚拟现实技术与产品的设计、装配和分析紧密地结合在一起。但目前大多数面向产品开发的虚拟环境存在着通用性和可重用性等问题。本文给出了一个虚拟装配环境软件体系结构,该体系结构基于统一建模语言UML和离散事件系统形式化描述体系DEVS思想,采用面向对象、可重用技术对该系统进行了分析设计,实现了软件体系结构的可扩展性、可重用性和易维护性等。 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献
