Jiage Huo, K. L. Keung, C. K. M. Lee, K. Ng, K. C. Li
Nowadays, Hong Kong International Airport faces the issues of saturation and overload. The difficulties of selecting taxiways and reducing the lead time at the runway holding position are the severe consequences that appeared from increasing the number of passengers and increased cargo movement to Hong Kong International Airport but without constructing a new runway. This paper is primarily about predicting flight delays by using machine learning methodologies. The prediction results of several machine learning approaches are compared and analyzed thoroughly by using real data from the Hong Kong International Airport. The findings and recommendations from this paper are valuable to the aviation and insurance industries. Better planning of the airport system can be established through predicting flight delays.

Business Applications for Current Developments in Big Data Clustering: An Overview 当前大数据集群发展的商业应用:概述
G. Hass, Parker Simon, R. Kashef
"The world's most valuable resource is no longer oil, but data" announces the headline of the May 6th, 2017 edition of The Economist; the digital revolution is here to stay. The primary currency of this movement is big data. The complexity of big data is defined as the relationships and how the data can be arranged with one another. Facebook has 30 billion pieces of unique information shared each month; this data's sheer size can cause an immeasurable amount of combinations for relational data. Analyzing this big data can reveal various useful insights for decision-makers. With the adoption of clustering analysis, patterns and hidden information can be developed from big raw data that can be used across many business problems and applications. In this paper, an overview of the state of the art of clustering analysis and its adoption in business applications in the era of big data is presented.
“世界上最有价值的资源不再是石油,而是数据”,这是《经济学人》2017年5月6日的头条新闻;数字革命将会持续下去。这场运动的主要货币是大数据。大数据的复杂性被定义为数据之间的关系以及如何排列数据。Facebook每个月有300亿条独特的信息被分享;该数据的绝对规模可能导致关系数据的不可估量的组合。分析这些大数据可以为决策者提供各种有用的见解。通过采用聚类分析,可以从可用于许多业务问题和应用程序的大原始数据中开发模式和隐藏信息。本文概述了聚类分析的现状及其在大数据时代商业应用中的应用。

Enablers and Barriers to the Implementation of Digital Twins in the Process Industry: A Systematic Literature Review 流程工业实施数字孪生的推动因素与障碍:系统文献综述
Matteo Perno, L. Hvam, Anders Haug
Since its first introduction in 2002, the interest in the concept of "Digital Twins" has grown exponentially among researchers and industry practitioners. An increasing number of Digital Twin implementations are made in many industries. Given the novelty of the concept, companies from any industry type face significant challenges when implementing Digital Twins. Furthermore, only little research has been conducted in the process industry, which may be explained by the high complexity of representing and modeling the physics behind the production processes in an accurate manner. This study aims at filling this gap by providing a clear categorization of the main barriers that process companies face when implementing Digital Twins of their assets, as well as the key enabling factors and technologies that can be leveraged to overcome such challenges. Furthermore, a model based on the findings from the literature study is proposed. The results indicate a dearth in the literature focused on the process industry, therefore, key learnings from other industry sectors are gathered, and suggestions for further research are proposed.
自2002年首次提出“数字孪生”概念以来,研究人员和行业从业者对“数字孪生”概念的兴趣呈指数级增长。在许多行业中,越来越多的数字孪生实现。考虑到这个概念的新颖性,任何行业类型的公司在实施数字孪生时都面临着重大挑战。此外,在过程工业中进行的研究很少,这可能是因为以准确的方式表示和建模生产过程背后的物理过程非常复杂。本研究旨在通过提供流程公司在实施其资产的数字孪生时面临的主要障碍的明确分类,以及可以用来克服这些挑战的关键促成因素和技术,来填补这一空白。在此基础上,提出了一个基于文献研究结果的模型。研究结果表明,过程工业相关文献较少,因此,本文收集了其他行业的重要经验,并提出了进一步研究的建议。

Effect of Network Structure and Preference Difference on Knowledge Transfer in Inter-organizational R&D Project 网络结构和偏好差异对组织间研发项目知识转移的影响
Xiaonan Wang, P. Guo, Ding Wang
An evolutionary game model of knowledge transfer in inter-organizational R&D projects was established, and its local stability was analyzed. Then, the complex network and preference theory are introduced to establish the game model of knowledge transfer in the cooperation network of inter-organizational R&D projects under the condition of preference differences and different network structures. Finally, the influence of key factors, preference difference and network structures on strategy selection is analyzed. The results show that the cost coefficient has a negative correlation with the level of knowledge transfer, while the increase of other coefficients promote knowledge transfer behavior. The increase of altruistic preference degree and the proportion of altruistic preference agents can promote knowledge transfer behavior, while the increase of competitive preference degree and the proportion of competitive preference agents can inhibit knowledge transfer behavior. Moreover, the level of knowledge transfer is higher in the scale-free network than in the small-world network in most cases. However, punishment plays a greater role in the small-world network.
建立了组织间研发项目知识转移的演化博弈模型,并对其局部稳定性进行了分析。然后,引入复杂网络和偏好理论,建立了偏好差异和不同网络结构条件下组织间研发项目合作网络中知识转移的博弈模型。最后,分析了关键因素、偏好差异和网络结构对策略选择的影响。结果表明,成本系数与知识转移水平呈负相关,而其他系数的增加促进了知识转移行为。利他偏好程度和利他偏好主体比例的增加对知识转移行为有促进作用,而竞争偏好程度和竞争偏好主体比例的增加对知识转移行为有抑制作用。此外,在大多数情况下,无标度网络中的知识转移水平高于小世界网络。然而,惩罚在小世界网络中起着更大的作用。

A. Protic, Ziyue Jin, R. Marian, K. Abd, D. Campbell, J. Chahl
With the increased demands of smarter manufacturing approaches around the world, the process of industrial digital transformation is being pushed in and by both industry and academia. Learning factories and testing laboratories have been developed for decades for teaching and training purposes in Academia. Nowadays, as the future trend in industry, Industry 4 is being merged into the latest development of learning factories and testing laboratories. This paper presents the development and implementation of a bi-directional digital twin application in an Industry 4 testing laboratory at University of South Australia. The solution is based on the establishment of OPC UA connection between two cobots of different brands, the use of NX Siemens as a CAD simulation platform and a SCADA system from Inductive Automation. Due to differences between system interfaces, communication between different modules was challenging. Python OPC UA servers were developed. The digital twin replicates the physical system and is driven by inputs from the assembly cell.

A Dynamic Feedback System Analysis on the Mechanism of Shipping Freight 航运运价机制的动态反馈系统分析
X. Bai, M. Xu, H. Jia
This study aims to investigate how congestions at ports affect the shipping freight market using a System Dynamics model, particularly in the liquified petroleum gas (LPG) maritime transportation market. We utilize maritime big data derived from the Automatic Identification System (AIS) for vessel tracking in the analysis. Our model captures the positive impact of port congestion, at its high level, on freight rate volatility when the shipping market is relatively in a tight condition. The proposed model provides insights into the shipping freight market development by innovatively considering port congestion level. The findings provide practical guidance for industrial practitioners to anticipate future freight rates based on the current congestion level and for port authorities to plan for infrastructure upgrades accordingly.

Robin Exner, Quoc Hao Ngo, Junjie Liang, Max Ellerich, Robin Günther, S. Schmitt, R. Schmitt
The objective of this paper is the optimization of failure management in production. For this purpose, the failure management process was considered in terms of its interaction with the operational activities in an assembly line. The process for production-related failure management is sufficiently described in the literature, but so far only a few approaches exist that analyze the interactions between production and quality processes in a dynamic model. In this paper, an existing model was taken up and further developed to represent individual assembly lines. The further developed model was programmed as a System Dynamics model that is provided in this paper.
本文的研究目标是优化生产中的故障管理。为此,故障管理过程是根据其与装配线上的操作活动的相互作用来考虑的。与生产相关的故障管理过程在文献中有充分的描述,但到目前为止,只有少数方法可以在动态模型中分析生产和质量过程之间的相互作用。在本文中,采用并进一步发展了现有的模型来表示单个装配线。将进一步发展的模型编程为本文提供的系统动力学模型。

Simulation Paper Planes a Way to Teach Lean Production 模拟纸飞机是教授精益生产的一种方式
L. A. Salazar, M. P. Revuelta
This article contributes to efforts to teach new methodologies for Industrial Engineering and Engineering Management. Therefore, the creation of the Simulation Paper Planes is presented to teach the principles of Lean Production. The document details the basic rules, general instructions, materials, manufacturing drawings, key performance indicators, and rounds of this simulation. This simulation is a direct and straightforward way to explain and demonstrate the importance of applying the Lean Principles in projects and production processes anywhere in the world. Of the 14 Lean principles, the authors managed to get participants to use 11. As future research, the authors call teachers and consultants to apply this simulation to students (Civil, Industrial, and Construction Engineering) and professionals, to generate a more extensive database. Also, they propose a line of research regarding the level of education in Lean practices between different countries, because, in general terms, undergraduate students in Chile were at the level of graduate students in Colombia.

Gamification in Assembly Training: A Systematic Review 装配训练中的游戏化:系统回顾
N. S. Uletika, B. Hartono, T. Wijayanto
In response to the advancement of digitalization technology, the future of assembly works and associated training methods seem to evolve. Gamification, i.e. the use of game design elements in nongame contexts seem to give a potential application for training procedures in the context of assembly work. However, the study on this field is still very limited. Thus, we investigate the following topics pertaining to assembly works and gamification: (a) how is the future of industrial assembly; (b) what methods are currently used to train the assembly workers; and (c) is gamification prospective for such training. From 20 out of 53 related studies, we eventually found the most relevant literatures. The results indicate that traditional training has not met the requirements of future trends, while augmented reality training methods, may offer extra benefits than the counterparts. The concept of gamification in which operators are directly involved, appropriate with skill-based assembly work requiring hands on experience. Further cognitive considerations and physiological measurements during experiment are required to improved HCI assembly work training systems design, especially within the gamification element context.
随着数字化技术的进步,装配工作的未来和相关的培训方法似乎也在不断发展。游戏化,即在非游戏环境中使用游戏设计元素似乎为组装工作中的培训程序提供了潜在的应用。然而,对这一领域的研究仍然非常有限。因此,我们研究了以下与装配工作和游戏化有关的主题:(a)工业装配的未来如何;(b)目前采用什么方法培训装配工人;(c)这种培训的游戏化前景。从53篇相关研究中的20篇中,我们最终找到了最相关的文献。结果表明,传统的培训方法已经不能满足未来趋势的要求,而增强现实培训方法可能比其他方法提供更多的好处。游戏化的概念,操作员直接参与,适合以技能为基础的组装工作,需要动手经验。在实验过程中需要进一步的认知考虑和生理测量来改进HCI装配工作培训系统的设计,特别是在游戏化元素的背景下。

Efficient Detection of Shilling’s Attacks in Collaborative Filtering Recommendation Systems Using Deep Learning Models 基于深度学习模型的协同过滤推荐系统中Shilling攻击的有效检测
Mahsa Ebrahimian, R. Kashef
Recommendation systems, especially collaborative filtering recommenders, are vulnerable to shilling attacks as some profit-driven users may inject fake profiles into the system to alter recommendation outputs. Current shilling attack detection methods are mostly based on feature extraction techniques. The hand-designed features can confine the model to specific domains or datasets while deep learning techniques enable us to derive deeper level features, enhance detection performance, and generalize the solution on various datasets and domains. This paper illustrates the application of two deep learning methods to detect shilling attacks. We conducted experiments on the MovieLens 100K and Netflix Dataset with different levels of attacks and types. Experimental results show that deep learning models can achieve an accuracy of up to 99%.
推荐系统,尤其是协同过滤推荐系统,很容易受到先令攻击,因为一些受利润驱动的用户可能会向系统注入虚假的个人资料来改变推荐输出。目前的先令攻击检测方法大多基于特征提取技术。手工设计的特征可以将模型限制在特定的领域或数据集,而深度学习技术使我们能够获得更深层次的特征,提高检测性能,并将解决方案推广到各种数据集和领域。本文阐述了两种深度学习方法在检测先令攻击中的应用。我们在MovieLens 100K和Netflix数据集上进行了不同级别和类型的攻击实验。实验结果表明,深度学习模型的准确率高达99%。

Current shilling attack detection methods are mostly based on feature extraction techniques. The hand-designed features can confine the model to specific domains or datasets while deep learning techniques enable us to derive deeper level features, enhance detection performance, and generalize the solution on various datasets and domains. This paper illustrates the application of two deep learning methods to detect shilling attacks.
