Modeling and simulating the impact of forgetting and communication errors on delays in civil infrastructure shutdowns

Zhe SUN, Cheng ZHANG, Pingbo TANG

《工程管理前沿（英文）》 2021年第8卷第1期页码 109-121 doi: 10.1007/s42524-019-0084-6

摘要： Handoff processes during civil infrastructure operations are transitions between sequential tasks. Typical handoffs constantly involve cognitive and communication activities among operations personnel, as well as traveling activities. Large civil infrastructures, such as nuclear power plants (NPPs), provide critical services to modern cities but require regular or unexpected shutdowns (i.e., outage) for maintenance. Handoffs during such an outage contain interwoven workflows and communication activities that pose challenges to the cognitive and communication skills of handoff participants and constantly result in delays. Traveling time and changing field conditions bring additional challenges to effective coordination among multiple groups of people. Historical NPP records studied in this research indicate that even meticulous planning that takes six months before each outage could hardly guarantee sufficient back-up plans for handling various unexpected events. Consequently, delays frequently occur in NPP outages and bring significant socioeconomic losses. A synthesis of previous studies on the delay analysis of accelerated maintenance schedules revealed the importance and challenges of handoff modeling. However, existing schedule representation methods could hardly represent the interwoven communication, cognitive, traveling, and working processes of multiple participants collaborating on completing scheduled tasks. Moreover, the lack of formal models that capture how cognitive, waiting, traveling, and communication issues affect outage workflows force managers to rely on personal experiences in diagnosing delays and coordinating multiple teams involved in outages. This study aims to establish formal models through agent-based simulation to support the analytical assessment of outage schedules with full consideration of cognitive and communication factors involved in handoffs within the NPP outage workflows. Simulation results indicate that the proposed handoff modeling can help predict the impact of cognitive and communication issues on delays propagating throughout outage schedules. Moreover, various activities are fully considered, including traveling between workspaces and waiting. Such delay prediction capability paves the path toward predictive and resilience outage control of NPPs.

Instrumented toys for assessing spatial cognition in infants

Domenico CAMPOLO, Fabrizio TAFFONI, Domenico FORMICA, Flavio KELLER, Eugenio GUGLIELMELLI

《机械工程前沿（英文）》 2011年第6卷第1期页码 82-88 doi: 10.1007/s11465-011-0208-0

摘要：

This paper describes an interdisciplinary approach to the assessment on infants’ behavior, with a focus on the technology. The goal is an objective, quantitative analysis of concurrent maturation of sensory, motor and cognitive abilities in young children, in relation to the achievement of developmental milestones. An instrumented block-box toy specifically developed to assess the ability to insert objects into holes is presented. The functional specifications are derived from experimental protocols devised by neuroscientists to assess spatial cognition skills. Technological choices are emphasized with respect to ecological requirements. An ad hoc calibration procedure is also presented which is suitable to unstructured environments. Finally, preliminary tests carried out at a local day-care with 12–24 months old infants are presented which prove the in-field usability of the proposed technology.

Mirror system based therapy for autism spectrum disorders

CHEN Wei, ZHANG Jing, DING Jun

《医学前沿（英文）》 2008年第2卷第4期页码 344-347 doi: 10.1007/s11684-008-0065-3

摘要： This paper reviews the present theories and empirical research of autisms’ cognitive research and mirror systems and introduces a new hypothesis about the causes of autism spectrum disorders (ASD): autistic mirror neuron dysfunction hypothesis. ASD subjects show obvious lack of the activation of the mirror system during the task of observation or emotional cognition. It is significant to investigate the mirror system for revealing the causes of autism and it is also helpful for developing new ways to diagnose or treat this disorder.

一个描述机器人团队形成的动态演化模型

李淑琴,程显毅,唐振民,杨静宇

《中国工程科学》 2006年第8卷第4期页码 28-31

摘要：

目前在多机器人领域，对组织、团队和群体概念比较混乱，团队形成的研究大都停留在定性分析阶段。借鉴Markov过程和进化计算，从协作主体层和能力层研究了机器人团队和组织的区别及团队的形成机制。提出并全面描述了一个机器人团队形成的动态演化模型，目前国内外尚无类似模型。该模型不仅能对机器人团队有一个整体描述，而且能定量描述团队形成时的动态演化过程。

深度IA双向智能 Personal View

Lei XU

《信息与电子工程前沿（英文）》 2020年第21卷第4期页码 558-562 doi: 10.1631/FITEE.1900541

摘要：概述了一个深度双向智能框架。由底向上方向有两个行为，一是获取信息形成适当的模式表示，二是抽象—自组织认知，简记为“A-S认知”，将输入模式抽象为概念，由一个标签表示，并通过自组织学习以理解模式构成的层次表示。而顶层内域中的行为统称为“A-I思维”，包含积累、融合、归纳、和灵感等。由顶向下方向也有两个行为，一个简称“I-S推理”，进行推理和综合，执行各种形象思维和问题求解任务，另一个是与环境交互，执行控制、通讯和检验的任务。在这个双向智能框架基础上，探讨了进行综合推理的可能性。
