现代技术正在持续不断地产生完全人造的系统。如通讯网络和计算机集成制造系统(CIMS)。这类系统显然是动态的,因为它们随时间演变。但它们一般很难用熟知的常微或偏微分(差分)方程建模。我们称此类系统为“离散事件动态系统”(DEDS)。最近的指导性文章《对于控制的挑战》特别把DEDS列为重要的未来研究方向。本文欲指出,此类系统在当今世界日趋普遍但尚无有效描述它们的动杰和解析的模型。人们不应过份强调现已很完善的建模体系,如连续变量动态系统(CVDS)中使用的微分方程的重要性。这种体系浸透到整个科学领域,促进了跨学科的交流,并影响着我们解决问题的方式。我认为,对DEDS所做的相对说来尚属原始的分析和
Modern technology is continually producing completely man-made systems. Such as communications networks and computer integrated manufacturing systems (CIMS). Obviously such systems are dynamic because they evolve over time. However, they are generally difficult to model using well-known ordinary or partial differential equations. We call such systems “Discrete Event Dynamics” (DEDS). A recent guidance article, “The Challenges for Control,” sets DEDS as an important future research area. This paper attempts to point out that such systems are becoming prevalent in today’s world but have not effectively described their models of dynamics and parsing. One should not overemphasize the importance of well-established modeling systems such as the differential equations used in continuous variable dynamic systems (CVDS). This system permeates the entire scientific community, promotes interdisciplinary exchanges and affects the way we solve problems. In my opinion, the relative analysis of DEDS is still the original analysis
