Managing Coordination Complexity in the Remanufacturing of Aircraft Engines

Qing Yang,Lu Zheng

《工程管理前沿（英文）》 2016年第3卷第2期页码 158-164 doi: 10.15302/J-FEM-2016022

摘要： The complexity of communication and coordination stemming from teams responsible for adjusting interdependent parameters of components is a fundamental feature in the aircraft engine remanufacturing engineering project. To manage coordination complexity, the features of the remanufacturing process of aircraft engine are analyzed and a systematic method is presented to measure and optimize the dependency between coupled components. Furthermore, quantitative models are built based on Design Structure Matrix (DSM) models to measure dependency strengths related to the parameter features of the components. Also, a two-stage DSM clustering criteria is used to reduce the complexity of an organization. An industrial example is provided to illustrate the proposed models. The results showed that the proposed approach can reduce total coordination complexity.

River Chief System (RCS): An experiment on cross-sectoral coordination of watershed governance

Longfei Wang, Jiaxin Tong, Yi Li

《环境科学与工程前沿（英文）》 2019年第13卷第4期 doi: 10.1007/s11783-019-1157-9

摘要：

The trans-regional characteristics of watershed governance produce more problems beyond the capacity of each individual water-related department, leading to the fragmentation of watershed management. The River Chief System (RCS) has experienced swift developments over the past decade in China by appointing the local government heads as river chiefs. RCS works efficiently in the short-term due to its superiority in the inclusion of clear responsibility, authority, and multi-sectoral collaboration. However, the characteristics of the authority-based vertical coordination of the hierarchical system remain unchanged, and therefore the problems of organizational logic and the responsibility dilemma still exist. Tasks including perfecting of laws, integrated watershed management, and public participation still need to be completed. RCS reflects the routine and characteristics of the migration of national governance, and as such provides new insights for other developing countries in the design of river management systems.

Distributed coordination inmulti-agent systems: a graph Laplacian perspective

Zhi-min HAN,Zhi-yun LIN,Min-yue FU,Zhi-yong CHEN

《信息与电子工程前沿（英文）》 2015年第16卷第6期页码 429-448 doi: 10.1631/FITEE.1500118

摘要： This paper reviews some main results and progress in distributed multi-agent coordination from a graph Laplacian perspective. Distributed multi-agent coordination has been a very active subject studied extensively by the systems and control community in last decades, including distributed consensus, formation control, sensor localization, distributed optimization, etc. The aim of this paper is to provide both a comprehensive survey of existing literature in distributed multi-agent coordination and a new perspective in terms of graph Laplacian to categorize the fundamental mechanisms for distributed coordination. For different types of graph Laplacians, we summarize their inherent coordination features and specific research issues. This paper also highlights several promising research directions along with some open problems that are deemed important for future study.

Review of human–robot coordination control for rehabilitation based on motor function evaluation

《机械工程前沿（英文）》 2022年第17卷第2期 doi: 10.1007/s11465-022-0684-4

摘要： As a wearable and intelligent system, a lower limb exoskeleton rehabilitation robot can provide auxiliary rehabilitation training for patients with lower limb walking impairment/loss and address the existing problem of insufficient medical resources. One of the main elements of such a human–robot coupling system is a control system to ensure human–robot coordination. This review aims to summarise the development of human–robot coordination control and the associated research achievements and provide insight into the research challenges in promoting innovative design in such control systems. The patients’ functional disorders and clinical rehabilitation needs regarding lower limbs are analysed in detail, forming the basis for the human–robot coordination of lower limb rehabilitation robots. Then, human–robot coordination is discussed in terms of three aspects: modelling, perception and control. Based on the reviewed research, the demand for robotic rehabilitation, modelling for human–robot coupling systems with new structures and assessment methods with different etiologies based on multi-mode sensors are discussed in detail, suggesting development directions of human–robot coordination and providing a reference for relevant research.

《信息与电子工程前沿（英文）》 2017年第18卷第6期页码 830-840 doi: 10.1631/FITEE.1700047

摘要：对于未来的第五代通信系统，干扰协调已经成为最具挑战性的问题，而大规模多输入多输出、小蜂窝和全双工技术均是在此背景下充满前景的技术。提出一个针对两层异构网络的干扰协调框架，该异构网络包含了一个装备大规模天线阵列的宏蜂窝基站和大量使用全双工技术的小蜂窝基站。因为带内全双工和带外全双工会产生不同的干扰模式，为了抑制干扰和最大化网络吞吐量，每个小蜂窝基站在无线回程链路的全双工模式都应慎重选择。为解决此模式选择问题，提出两种集中式算法，分别是遗传算法和贪心算法。此外，为了更充分降低宏蜂窝基站的计算开销，进一步提出一种基于代价的分布式图染色算法。仿真结果表明：提出的算法显著提高了系统吞吐量。

《信息与电子工程前沿（英文）》 2016年第17卷第9期页码 907-918 doi: 10.1631/FITEE.1500227

摘要：概要：针对城市主干道的交通流特征，提出了一种新的交通信号协调控制方法。其核心控制算法包括两个模块：控制子区划分模块和信号协调控制模块。本文首先分析了相邻交叉口的路段长度、路段交通密度以及交叉口信号配时参数对相邻交叉口交通关联度的影响，然后设计了基于分层结构的相邻交叉口交通关联度的模糊计算方法和基于关联度的主干道控制子区划分方法。接着提出了一种控制子区协调控制算法，根据一段时间内交通流信息计算控制子区公共信号周期、路段上下行相位差和各路口的绿信比。实际应用表明该控制方法能有效降低主干道交通流平均旅行时间和平均停车率，效果令人满意。

Organizational dynamics in adaptive distributed search processes: effects on performance and the role of complexity

Friederike WALL

《信息与电子工程前沿（英文）》 2016年第17卷第4期页码 283-295 doi: 10.1631/FITEE.1500306

摘要： In this paper, the effects of altering the organizational setting of distributed adaptive search processes in the course of search are investigated. We put particular emphasis on the complexity of interactions between partial search problems assigned to search agents. Employing an agent-based simulation based on the framework of NK landscapes we analyze different temporal change modes of the organizational set-up. The organizational properties under change include, for example, the coordination mechanisms among search agents. Results suggest that inducing organizational dynamics has the potential to increase the effectiveness of distributed adaptive search processes with respect to various performance measures like the final performance achieved at the end of the search, the chance to find the optimal solution of the search problem, or the average performance per period achieved during the search process. However, results also indicate that the mode of temporal change in conjunction with the complexity of the search problem considerably affects the order of magnitude of these beneficial effects. In particular, results suggest that organizational dynamics induces a shift towards more exploration, i.e., discovery of new areas in the fitness landscape, and less exploitation, i.e., stepwise improvement.

基于车联网的信号灯协同控制 Article

李婉, 班学钢

《工程（英文）》 2020年第6卷第12期页码 1463-1472 doi: 10.1016/j.eng.2020.10.009

摘要：

本文提出了一个基于车联网（CV）环境的交通主干道信号灯协同控制的模型及其求解方法。首先，我们将信号优化与协同控制问题归结为一个混合整数非线性规划（MINLP）。通过考虑单个车辆轨迹的最小油耗和行程时间求解最优相位持续时间和相位差。由于模型的复杂性，我们将问题分解为两个层次：使用动态规划（DP）优化相位持续时间的交叉路口层，以及用于优化所有交叉路口相位差的干道交通层。同时，我们开发了一种基于预测的方法以求解上述双层优化模型。在各种场景下，我们利用交通模拟对模型进行了测试。与传统的感应信号灯协同控制相比，求解MINLP和双层优化模型生成的信号时序规划可以合理地提升交通信号灯控制性能和路网的服务水平。在高密度的交通流量的环境中并考虑不同车辆类型时，与感应信号灯相比，上述双层优化模型的求解法使路网总成本降低了3.8%，MINLP的应用使系统总成本降低了5.9%。这也表明对于交通密度相对较高的干道交通来说，本文提出的协同控制方案效果显著。而仿真结果也表明对于同时拥有主要道路和次要道路的交叉路口而言，面向主要道路进行的协同控制对次要道路上的车辆几乎没有影响。

近程毫米波合成孔径辐射计被动测距原理

王本庆,李兴国

《中国工程科学》 2010年第12卷第3期页码 95-99

摘要：

毫米波合成孔径技术利用了物体自身辐射电磁波的相位信息，采用很少阵元就能实现实时成像，但目前合成孔径技术只是限于亮温成像，缺少了目标的距离信息，这对于目标探测与识别很不利。提出在近程条件下合成孔径被动测距原理和相应的双正交傅立叶变换算法，并给出了近程距离分辨率公式，近程成像的特点是成像公式中存在二次相位因子，而且距离分辨率和距离的平方成反比。毫米波合成孔径被动成像可以同时得到物体辐射的亮温分布和距离分布，能够有效克服离焦引起的图像模糊，对图像的反降晰和目标识别具有重要意义。

黄捷1,2,3,莫智斌1,2,3,张祯毅1,2,3,陈宇韬1,2,3

《信息与电子工程前沿（英文）》 2022年第23卷第8期页码 1174-1188 doi: 10.1631/FITEE.2100280

摘要：针对人—多机器人协同系统提出一种基于行为控制框架的带记忆强化学习任务管理器（RLTS）。由于重复的人工干预，现有人—多机器人协同系统决策时间成本高、任务跟踪误差大，限制了多机器人系统的自主性。此外，基于零空间行为控制框架的任务管理器依赖手动制定优先级切换规则，难以在多机器人和多任务情况下实现最优行为优先级调整策略。提出一种带记忆强化学习任务管理器，基于零空间行为控制框架融合深度Q-网络和长短时记忆神经网络知识库，实现任务冲突时最优行为优先级调整策略以及降低人为干预频率。当机器人在紧急情况下置信度不足时，所提带记忆强化学习任务管理器会记忆人类干预历史，在遭遇相同人工干预情况时重新加载历史控制信号。仿真结果验证了该方法的有效性。最后，通过一组受外界噪声和干扰的移动机器人实验，验证了所提带记忆强化学习任务管理器在不确定现实环境中的有效性。
