- Cyber-physical-social System in Intelligent Transportation被引量：14
- 2015年
- A cyber-physical system (CPS) is composed of a physical system and its corresponding cyber systems that are tightly fused at all scales and levels. CPS is helpful to improve the controllability, efficiency and reliability of a physical system, such as vehicle collision avoidance and zero-net energy buildings systems. It has become a hot R&D and practical area from US to EU and other countries. In fact, most of physical systems and their cyber systems are designed, built and used by human beings in the social and natural environments. So, social systems must be of the same importance as their CPSs. The indivisible cyber, physical and social parts constitute the cyber-physical-social system (CPSS), a typical complex system and it's a challengeable problem to control and manage it under traditional theories and methods. An artificial systems, computational experiments and parallel execution (ACP) methodology is introduced based on which data-driven models are applied to social system. Artificial systems, i.e., cyber systems, are applied for the equivalent description of physical-social system (PSS). Computational experiments are applied for control plan validation. And parallel execution finally realizes the stepwise control and management of CPSS. Finally, a CPSS-based intelligent transportation system (ITS) is discussed as a case study, and its architecture, three parts, and application are described in detail. © 2014 Chinese Association of Automation.

- 提高核电站安全可靠性的平行系统方法被引量：14
- 2012年
- 安全可靠性是核电站存在和发展的生命线,目前它还主要是通过人的经验和严格管理等来保证,但其智能性和科学性还不够.核电站是一个涉及多方面的动态变化要素的复杂系统,现有控制、仿真和管理技术还不能为其生产运行和管理提供安全可靠的充分保证.本文以ACP方法为基础,基于信息技术最新发展成果,提出了采用自上而下的规划和自下而上的设计相结合的方法,来开发"核电站可靠性规划和设计软件包",使得核电站在建造前就有了安全可靠方面的科学依据.进而提出平行系统方法,分析其基本原理和成功应用实例,并介绍其在核电站中应用的人工系统、计算试验和平行执行的具体内容,给出了PTS、PES和PMS等具体应用.
