A Meta-Heuristic Approach for Dynamic Process Planning in Reconfigurable Manufacturing Systems 可重构制造系统动态工艺规划的元启发式方法
Fu-Shiung Hsieh
Reconfigurable Manufacturing Systems (RMS) is a paradigm to flexibly deal with frequent changing demand and technologies. With the advancement of technology and more and more sensors and machines are connected, the world quickly enter the era of Internet of Things (IoT), which provides infrastructure for RMS. However existing studies lack a formalism that provides a framework for the development of RMS, from modeling, design to implementation. In particular, an important issue is design of dynamic process planner for RMS. This paper focuses on the development of a dynamic process planning method for the development of RMS. Modeling and managing RMS in manufacturing sector are challenging issues due to the complex workflows in the system. Recent progress in artificial intelligence and bio-inspired optimization technology provides a solid background to develop a framework to provide dynamic process planning for RMS in IoT-enabled manufacturing environment. In this paper, we propose a process planning method based on multi-agent systems (MAS) using Petri Nets to specify the workflows and capabilities of resources in the system and develop a solution algorithm based on a meta-heuristic method to solve the process planning problem based on discrete Particle swarm optimization (DPSO) approach The proposed method is illustrated by a several examples.
可重构制造系统(RMS)是一种灵活处理频繁变化的需求和技术的范式。随着技术的进步,越来越多的传感器和机器连接在一起,世界迅速进入物联网(IoT)时代,物联网为RMS提供了基础设施。然而,现有的研究缺乏为RMS的开发提供一个从建模、设计到实现的框架的形式化理论。其中一个重要的问题是动态过程规划器的设计。本文重点研究了一种面向RMS开发的动态过程规划方法。由于制造系统中复杂的工作流程,制造系统的建模和管理是一个具有挑战性的问题。人工智能和生物优化技术的最新进展为开发框架提供了坚实的背景,为物联网制造环境中的RMS提供动态流程规划。本文提出了一种基于多智能体系统(MAS)的工艺规划方法,使用Petri网来指定系统中资源的工作流程和能力,并开发了一种基于元启发式方法的求解算法来解决基于离散粒子群优化(DPSO)方法的工艺规划问题,并通过几个实例说明了所提出的方法。

Mounira Hmayda, R. Ejbali, M. Zaied
Automatic identification of television programs in the TV stream is an important task for operating archives and represent a principal source of multimedia information.. The goal of the proposed approach is to enable a better exploitation of this source of video by multimedia services (i.e., TV-On-Demand, catch-up TV), social community, and video-sharing pla forms (Vimeo, Youtube, Facebook…) This paper presents a new spatio-temporal approach to identify the programs in TV stream using deep learning in two main steps. A database for video of visual jingles is constructed for training. In the test we use same jingles program type in order to identify the various program types in the TV stream. The main idea of identification process consists in using the principal of auto-encoder. After presenting the proposed approach, the paper overviews the encouraging experimental results on several streams extracted from different channels and composed of several programs. Comparison experiments to similar works have been carried out on the TRECVID 2017 database. We show significant improvements to TV programs identification exceed 95 %.
电视节目流的自动识别是档案管理的重要任务,是多媒体信息的主要来源。提出的方法的目标是通过多媒体服务(即电视点播,追赶电视),社交社区和视频共享平台形式(Vimeo, Youtube, Facebook…)更好地利用这种视频来源。本文提出了一种新的时空方法,使用深度学习在两个主要步骤中识别电视流中的节目。建立了视觉广告歌曲视频数据库,用于训练。在测试中,我们使用相同的jingles节目类型,以便识别电视流中的各种节目类型。识别过程的主要思想是利用自编码器原理。在介绍了该方法的基础上,本文概述了从不同通道提取并由多个程序组成的几个流的令人鼓舞的实验结果。在TRECVID 2017数据库上进行了与同类作品的对比实验。电视节目识别率显著提高,超过95%。

Agent Collaboration in Intelligent Parking Lot Systems: Dynamic Generation of Commitment Protocol 智能停车场系统中的Agent协作:承诺协议的动态生成
Jing Wang, Wei Liu, Shuang Li
Agent collaboration is a fundamental part of multi-agent systems when an agent cannot accomplish a goal by itself. Such collaborations are usually regulated by commitment protocols, which are typically defined at design-time. However, in many situations a protocol may not exist or be predefined at design-time which may not fit the needs of the agents when environment changes. In order to deal with such situations, agents should be able to generate protocols at run-time. In this paper, we combined commitment with capability. Firstly, we proposed the capability matching method to generate commitment protocols dynamically at run-time. Secondly, we combined capability with commitment and extended its traditional definition. Thirdly, we compared the forms, generation time and execution time of typical and extended commitments. At last, we introduced the criteria of profit to select the optimal protocol. The application of our approach will be demonstrated in intelligent parking lot systems.
智能体协作是多智能体系统的基本组成部分,当一个智能体不能单独完成一个目标时。这种协作通常由承诺协议来规范,而承诺协议通常是在设计时定义的。然而,在许多情况下,协议可能不存在或在设计时预定义,这可能不适合环境变化时代理的需求。为了处理这种情况,代理应该能够在运行时生成协议。在本文中,我们将承诺与能力结合起来。首先,提出了在运行时动态生成承诺协议的能力匹配方法。其次,我们将能力与承诺结合起来,对其传统定义进行了扩展。第三,对典型承诺和延伸承诺的形式、产生时间和执行时间进行了比较。最后,引入了利润准则来选择最优协议。我们的方法将在智能停车场系统中得到应用。

Application Classification Based on Preference for Resource Requirements in Virtualization Environment 基于资源需求偏好的虚拟化应用分类
Shumin Qiao, Binbin Zhang, Weiyi Liu
Different applications have different preferences for resource requirements. In virtualization environment, if multiple virtual machines hosted on the same server have the same resource requirement preference, performance can be greatly affected for the resource competition between virtual machines. In this paper, we propose an approach to use a feature weighting naive Bayes classifier with Laplacian correction model to classify the applications according to the characteristics of application accessing to CPU, memory, hard disk, and the L2 cache collected using profiling. Based on the application classification, the virtual machines running applications of different types can be deployed on the same physical host. The experiments show that this method can achieve high classification accuracy. And this methods avoid the performance bottleneck due to resource competition to a certain extent.
不同的应用程序对资源需求有不同的偏好。在虚拟化环境中,如果托管在同一台服务器上的多个虚拟机具有相同的资源需求优先级,则虚拟机之间的资源竞争会对性能产生很大的影响。在本文中,我们提出了一种基于特征加权朴素贝叶斯分类器和拉普拉斯校正模型的方法,根据应用程序访问CPU、内存、硬盘和二级缓存的特征对应用程序进行分类。根据应用分类,可以将运行不同类型应用的虚拟机部署在同一台物理主机上。实验表明,该方法能达到较高的分类精度。该方法在一定程度上避免了资源竞争带来的性能瓶颈。

Efficient Data Gathering in Wireless Sensor Networks with Fixed-Group Method 基于固定群方法的无线传感器网络高效数据采集
Zhansheng Chen, Hong Shen
Topology control based on appropriate cluster head election can drastically reduce energy consumption, balance traf?c load on sensor nodes and extends the lifetime of the network. In this paper, an ef?cient data gathering multihop routing approach based on ?xed-group for wireless sensor networks is proposed. Our proposed protocol, FGMRP (Fixed-Group based Multi-hop Routing Protocol), divides the monitoring area into several groups according to node intimacy, optimizes energy consumption among nodes in each group by performing adaptive cluster head round-robin rotations based on residual energy, concentration and centrality, and balances energy consumption among groups through a ?tness routing algorithm which considers node residual energy, forwarding distance and radial angle. Simulation results show that the FGMRP protocol effectively balances the energy consumption among nodes, achieves better monitoring performance and signi?cantly increases network lifetime as compared to the existing routing protocols, taking monitoring quality, the amount of data acquisition and network lifetime as evaluation indices.

Cai-xin Han
The development of regional economy benefits from transportation infrastructure upgrading. Take central China as the example, based on its railway passenger and freight volumes and turnover volumes, GDP and other macro-economic data, this paper uses co-integration analysis, the error correction model and Granger causal relation test to empirically study the internal relationship between these two kinds of indexes. Results show that GDP has long-term co-integration relationship with all these transportation indexes, and the elasticity coefficients of passenger volume, passenger and freight turnover volumes to GDP are 0.5959, 14.9931 and 1.9916 respectively, among which the passenger turnover volume has a significant effect on economic growth. The construction and operation of the eight vertical and eight horizontal high-speed railway network will definitely further boost the rapid development of regional economy.

Multi-Blockchain Model for Central Bank Digital Currency 央行数字货币的多区块链模型
He Sun, Hongliang Mao, Xiaomin Bai, Zhidong Chen, Kai Hu, Wei Yu
Digital Currency for Central Bank is becoming an important policy for country. CBDC (Central Bank Digital Currency) model should take advantages in the supervision, payment and consumption. Blockchain possesses the feature of de-centrality, tamper-resistant, and traceability. So this paper attempts to use the blockchain as the fundamental technology of CBDC. However, the challenges such as the protection for users privacy, supervision and transaction speed should be overcome. This paper proposes a CBDC model called MBDC which is based on the permission blockchain technology. The model makes use of the multi-blockchain architecture and ChainID to improve the models scalability and process payments more quickly. In this model, central bank and commercial banks and other agencies build and maintain the blockchain. On one hand, central bank could master the issuance of currency. On the other hand, relying on the user account address protocol, central bank could separate the users identity and transaction information. In this way, central bank could avoid double-spending issues and protect users privacy. In addition, the establishment of DC (Data Center) and layers of supervision provide strong supervision for the model. Finally, we also demonstrate, both theoretically and experimentally, the performance of model on the scalability and the speed of transaction execution etc.
中央银行数字货币正成为国家的一项重要政策。CBDC(中央银行数字货币)模式应该在监管、支付和消费方面发挥优势。区块链具有去中心化、防篡改、可追溯性等特点。因此,本文试图将区块链作为CBDC的基础技术。但是,用户隐私保护、监管、交易速度等方面的挑战需要克服。本文提出了一种基于权限区块链技术的CBDC模型MBDC。该模型利用多区块链架构和ChainID来提高模型的可扩展性,更快地处理支付。在这种模式下,中央银行和商业银行等机构建立和维护区块链。一方面,中央银行可以掌握货币的发行。另一方面,依靠用户账户地址协议,中央银行可以将用户身份和交易信息分离。通过这种方式,央行可以避免双重支出问题,保护用户隐私。此外,DC(数据中心)的建立和层层监管为该模型提供了强有力的监管。最后,从理论和实验两方面验证了该模型在可扩展性和事务执行速度等方面的性能。

The model makes use of the multi-blockchain architecture and ChainID to improve the models scalability and process payments more quickly. In this model, central bank and commercial banks and other agencies build and maintain the blockchain. On one hand, central bank could master the issuance of currency. On the other hand, relying on the user account address protocol, central bank could separate the users identity and transaction information. In this way, central bank could avoid double-spending issues and protect users privacy. In addition, the establishment of DC (Data Center) and layers of supervision provide strong supervision for the model. Finally, we also demonstrate, both theoretically and experimentally, the performance of model on the scalability and the speed of transaction execution etc.","PeriodicalId":119197,"journal":{"name":"2017 18th International Conference on Parallel and Distributed Computing, Applications and Technologies (PDCAT)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126012630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
