Avoiding Counterfeits and Achieving Privacy in Supply Chain: A Blockchain Based Approach 在供应链中避免假冒和实现隐私:基于区块链的方法
Prem Ratan Baranwal
Counterfeiting is one of the biggest threats to the current RFID-based supply chain industry. There are several blockchain solutions suggested which preserve RFID tag uniqueness and bring all the parties to a common platform. However, they are based on some common assumptions such as an adversary may need a large number of tags to retrieve the product details. Besides, these tags can be easily cloned post supply chain and reused for counterfeiting. Lack of proper mechanisms to preserve trade secrets such as volumes and supplier relationships is also a major challenge faced by most of these systems in this competitive market. We propose a novel product ownership tracking system based on blockchain for the supply chain industry which solves these problems while allowing access to the trade secrets only to its supply chain participants. The proposed protocol is based on Shamir's threshold Scheme where a secret key is used to decrypt the trade secrets and its shares are distributed among the supply chain parties during the ownership transfer process. Product verification is done by the consumer as well with the help of the retailer at the time of sale.
假冒是当前基于rfid的供应链行业的最大威胁之一。有几种区块链解决方案可以保持RFID标签的唯一性,并将所有各方带到一个共同的平台上。然而,它们是基于一些常见的假设,例如攻击者可能需要大量的标记来检索产品详细信息。此外,这些标签很容易在供应链后被复制,并被重复用于伪造。缺乏适当的机制来保护商业秘密,如数量和供应商关系,也是大多数这些系统在这个竞争激烈的市场中面临的主要挑战。我们为供应链行业提出了一种基于区块链的新型产品所有权跟踪系统,该系统解决了这些问题,同时只允许其供应链参与者访问商业秘密。该协议基于Shamir阈值方案,使用密钥对商业秘密进行解密,并在所有权转移过程中在供应链各方之间分配其份额。产品验证也由消费者在销售时在零售商的帮助下完成。

A Framework for developing Teamwork Enabled Services in Smart City Domains 在智慧城市领域开发团队协作服务的框架
Paraskevi Tsoutsa, Omiros Iatrellis, O. Ragos, P. Fitsilis
Services that collaborate alongside other services or systems for performing tasks, need to be aware of either predetermined or other abrupt and unexpected behaviors in other to adapt theirs. The service behaviors we consider are performed in smart city domains which are dynamic environments where continuously new services appear, that usually have a large variation in the way they perform the same task. We use roles having teamwork behavior to represent the composition procedure in such domains, and we model the team of services through the individual behavior of each participant as well as their group goal. In this paper, we present a framework, which consists of the approach and IT system in order to serve the choreography between a large number of heterogeneous services so as to achieve a seamless and cooperative environment suitable for a smart city. This enables composite city services to adapt their behavior during execution and themselves intervene from inside the team if a possible unexpected behavior happens during the service activity, in order to run proactively and avoid obstacles or collisions. A scenario from a smart city domain illustrates that, services having different teamwork abilities are composed to a new one which inherits teamwork features and combines them to something novel.
与其他服务或系统协作执行任务的服务需要了解其他服务或系统中预定的或其他突然和意外的行为,以适应它们的行为。我们考虑的服务行为是在智能城市领域中执行的,这些领域是动态环境,不断出现新的服务,通常在执行相同任务的方式上有很大的变化。我们使用具有团队合作行为的角色来表示这些领域中的组合过程,并通过每个参与者的个人行为及其团队目标对服务团队进行建模。在本文中,我们提出了一个框架,该框架由方法和IT系统组成,以服务于大量异构服务之间的编排,从而实现适合智慧城市的无缝协作环境。这使得复合城市服务能够在执行期间调整其行为,并在服务活动期间发生可能的意外行为时从团队内部进行干预,以便主动运行并避免障碍或碰撞。智慧城市领域的一个场景说明,将具有不同团队合作能力的服务组合成一个继承团队合作特征的新服务,并将它们组合成一个新的服务。

D. H. Syahchari, E. Kuncoro, H. Saroso, Darjat Sudrajat, E. V. Zanten
A dry port (or land port) is an inland area or intermodal port directly connected to a seaport. Cikarang Dry Port, as one of the best performing dry ports among other dry ports in Indonesia, has only contributed 18% to the loading and unloading volume at Tanjung Priok Port. This study aims to examine the impact of supply chain collaboration and Service Stakeholder Commitment on the performance of dry port companies. The data was collected through a questionnaire that included 55 responses from Cikarang Dry port and maritime logistics companies in Jakarta. The hypotheses were tested by multiple regression. The results of this study confirm that Collaboration in the Supply Chain and the Commitment of Stakeholders in the Service have a positive impact on the performance of port companies. This study provides inspiration for managers to recognize the positive results of supply chain collaboration between service stakeholder engagement organizations to improve port performance in the port supply chain.

Applications of Big Data Analytics in Supply Chain Management: Findings from Expert Interviews 大数据分析在供应链管理中的应用:来自专家访谈的发现
P. Brandtner, Chibuzor Udokwu, Farzaneh Darbanian, T. Falatouri
The increased amount of data being generated in virtually every context provides huge potential for a variety of organisational application fields, one of them being Supply Chain Management (SCM). The possibilities and use cases of applying this new type of data, i.e. Big Data (BD), is huge and a large body of research has already been conducted in this area. The current paper aims at identifying the understanding and the applications of BD not from an academic but a practitioners’ point of view. By applying expert interviews, the main aim is to identify (i) a definition of Big Data from SCM practitioners’ point of view, (ii) current SCM activities and processes where BD is already used in practice, (iii) potential future application fields for BD as seen in SCM practice and (iv) main hinderers of BD application. The results show that Big Data is referred to as complex data sets with high volumes and a variety of sources that can't be handled with traditional approaches and require data expert knowledge and SCM domain knowledge to be used in organisational practical. Current applications include the creation of transparency in logistics and SCM, the improvement of demand planning or the support of supplier quality management. The interviewed experts coincide in the view, that BD offers huge potential in future SCM. A shared vision was the implementation of real-time transparency of Supply Chains (SC), the ability to predict the behavior of SCs based on identified data patterns and the possibility to predict the impact of decisions on SCM before they are taken.
几乎在每个环境中生成的数据量都在增加,这为各种组织应用领域提供了巨大的潜力,其中之一就是供应链管理(SCM)。应用这种新型数据,即大数据(BD)的可能性和用例是巨大的,在这一领域已经进行了大量的研究。本文旨在从实践者的角度,而不是从学术的角度,确定对商业发展的理解和应用。通过采用专家访谈,主要目的是确定(i)从供应链管理从业者的角度对大数据的定义,(ii)目前的供应链管理活动和流程中已经在实践中使用了业务流程,(iii)在供应链管理实践中看到的业务流程的潜在未来应用领域,以及(iv)业务流程应用的主要障碍。结果表明,大数据是指具有高容量和各种来源的复杂数据集,无法用传统方法处理,需要数据专家知识和SCM领域知识才能在组织实践中使用。目前的应用包括在物流和供应链管理中建立透明度,改善需求计划或支持供应商质量管理。受访专家一致认为,BD在未来供应链管理中具有巨大的潜力。一个共同的愿景是实现供应链的实时透明度,基于识别的数据模式预测供应链行为的能力,以及在做出决策之前预测对供应链的影响的可能性。

The Application of Machine Learning Models in the Prediction of PM2.5/PM10 Concentration 机器学习模型在PM2.5/PM10浓度预测中的应用
Xinzhi Lin
The current world economy and science are in an era of rapid development, and Beijing is experiencing chronic air pollution. The air quality is important to the travel of people, development of enterprise and normal operation of traffic. PM2.5 and PM10 are the main components which cause the air pollution, and it's very meaningful to predict their concentration in the air [1]. Although some traditional models (like basic linear regression) have been proposed to predict the content of PM2.5/PM10, the quantities of variables included to predict the concentration are few and it executes with low efficiency and low accuracy. In the big data era, it's necessary to build the model which can execute the big data kinds and sets. With the adequate data sets from different meteorological stations in Beijing, we can use the more abundant variables such as mass of SO2, NO2, wind direction and other weather observations to predict the content of PM2.5/PM10. We build the machine learning models with higher efficiency, accuracy and stronger learning ability, whose primary algorithms include: multiple linear regression, decision tree, boosting and random forest based on decision tree and neural network. The result demonstrates that the prediction effect of the models is based on neural network and ensemble learning. Boosting performs best among these models, which achieves R-square 84.2% and 75.7% on the test set for the PM2.5 and PM10, respectively.
当今世界经济和科学正处于快速发展的时代,而北京正经历着长期的空气污染。空气质量关系到人们的出行、企业的发展和交通的正常运行。PM2.5和PM10是造成大气污染的主要成分,对其在空气中的浓度进行预测具有重要意义[1]。虽然已经提出了一些传统的模型(如基本线性回归)来预测PM2.5/PM10的含量,但用于预测浓度的变量数量少,执行效率低,精度低。在大数据时代,有必要建立能够执行大数据种类和集合的模型。在北京市各气象站数据充足的情况下,我们可以利用SO2质量、NO2质量、风向等较为丰富的气象观测变量预测PM2.5/PM10的含量。我们构建了效率更高、精度更高、学习能力更强的机器学习模型,其主要算法包括:基于决策树和神经网络的多元线性回归、决策树、boosting和随机森林。结果表明,该模型的预测效果是基于神经网络和集成学习。在这些模型中,Boosting的表现最好,在PM2.5和PM10的测试集上分别达到了84.2%和75.7%的r方。

Logging Multi-Component Supply Chain Production in Blockchain 在区块链中记录多组件供应链生产
Y. Madhwal, Ivan Chistiakov, Y. Yanovich
The supply chain is a thriving industry where numerous parties have different interests. Subsequently, the immense volume of data produced is difficult to audit. Some information can be lost or intentionally distorted in the process. Blockchain as an open, public, borderless, neutral, and censorship-resistant architecture can significantly complement supply chains.

供应链是一个蓬勃发展的行业,各方都有不同的利益。随后,产生的大量数据难以审计。在这个过程中,一些信息可能会丢失或被故意扭曲。区块链作为一个开放、公共、无国界、中立和抗审查的架构,可以显著补充供应链。在这项工作中提出了一种新的供应链架构,其中标记化的有向无环超图(DAG)表示现实世界的生产过程。以某防气溶胶呼吸器生产为例进行说明。通过标记多组件产品的所有部分,供应链数据被自动标记为时间戳并得到保护。此外,DAG设计允许人们追溯最终产品的所有元素到它们的起源。区块链可以正式审计整个供应链,而不需要从一个地方到另一个地方。单一的不可损坏的操作日志为公正的声誉系统的出现创造了有利的环境。

The Role of End Users in Efficient Business Intelligence Solutions: A Preliminary Study 终端用户在高效商业智能解决方案中的作用:初步研究
Marianne Buus Jorgensen, Tobias Christensen, Tanja Svarre
Business intelligence (BI) is a highly regarded tool used to enhance decision-making and business procedures. Numerous studies argue for its effectiveness. However, the role of end users in ensuring efficient and effective BI solutions has received little attention in the literature. This paper presents a study of interviews with four BI end users to identify their influence on the efficiency of BI solutions. The interviews depart from theories within human-computer interaction (HCI) and information architecture (IA) to reveal users’ perspectives on actively engaging with BI solutions in everyday work tasks. The qualitative interviews demonstrate that users recognize the potential of working with BI and that engaged users support the efficient use of BI solutions in professional organizations. The study concludes that more research should be conducted in this field to increase our understanding of users as critical factors in the efficient use of BI solutions in organizations.
商业智能(BI)是一种备受推崇的工具,用于增强决策和业务流程。大量研究证明了它的有效性。然而,最终用户在确保高效和有效的BI解决方案中的作用在文献中很少受到关注。本文介绍了对四个BI最终用户的访谈研究,以确定他们对BI解决方案效率的影响。访谈从人机交互(HCI)和信息架构(IA)的理论出发,揭示用户在日常工作任务中积极参与BI解决方案的观点。定性访谈表明,用户认识到使用BI的潜力,并且参与其中的用户支持在专业组织中有效使用BI解决方案。该研究的结论是,应该在这个领域进行更多的研究,以增加我们对用户作为组织中有效使用BI解决方案的关键因素的理解。
