敏捷后勤系统的分布式仿真体系结构 总被引:1,自引:0,他引:1
针对敏捷后勤分布式仿真系统的构造需求,分析了仿真体系结构及系统描述方法的研究现状。应用主体信念-目标-意图(belief-desire-intention,BDI)的Petri网建模方法建立了描述敏捷后勤系统智能和分布特性的Petri网模型。在此基础上,提出了基于高层体系结构(high level architecture,HLA)的敏捷后勤系统分布式仿真体系结构,给出了该类系统的仿真策略。该仿真体系结构将集中式仿真和分布式仿真相结合,较好地反映了敏捷后勤系统的智能性、层次性、分布性、自治性、交互性、动态性等特性。 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

This paper presents an outline of an Oriental systems methodology: the Wuli Shili Renli approach (WSR). The basic theme of WSR contends that wuli (regularities in objective existence), shili (ways of seeing and doing), and renli (patterns underlying human relations) constitute a differentiated whole that conditions systems projects. WSR suggests that we should design and employ appropriate methods to address and tackle wuli shili and renli elements in a theoretically informed and systemic way. The background, philosophy, process, principles, and some practical applications of the methodology are preliminarily outlined. 相似文献
