The network of interconnected and synchronized machines, instruments, and other such devices in the industrial sphere is known as the Industrial Internet of Things. Smart sensors and actuators are integrated into industrial machines to enhance industrial activities and business-related applications with little to no human input. The analysis of the real-time data that is obtained from this vast internetwork of machinery allows for greater streamlining in the industrial processes and thereby provides an even greater benefit to businesses which adopt the IIoT framework. This special edition focuses on analyzing the interdependence and unavoidable overlap of big data analytics and IIoT. Businesses and industrial pursuits are often shaped by dynamic demands, changing environments, and even socio-political flux. In the rapidly evolving world of today, these catalysts of change may make it difficult for businesses to keep pace. As a solution to this problem, IIoT effectively facilitates intelligent industrial and customer-level operations by using advanced data analytics to positively transform business outcomes. With the accelerated advancements in IIoT, we can soon expect billions of interconnected machines to stream unprecedented volumes of sensor data at remarkable speeds. According to a report by the International Data Corporation (IDC), the big data and analytics market, which reached $60 billion worldwide in 2018, is expected to grow at a 5-year compound annual growth rate of 12.5%. An incline of this magnitude can be attributed at large to the growing importance of automation in industrial enterprises. This explosive growth in the number devices in IIoT networks and the consequential rise in the amount of data produced and consumed is an apt reflection of how the growth of big data and IIoT are mutually beneficial to one another. Businesses are benefitted by IIoT in terms of increased revenue, reduced costs, and increased efficiency. However, merely generating a large amount of data is not the end goal. The data streamed from IIoT sensors only become useful if the data is appropriately analyzed. Considering the sheer volume of the influx of data, storing, processing, and analyzing this data is prone to become problematic due to limitations in computational power, inadequate networking capacities, and insufficient storage. Security concerns also pose a large threat to the convergence of IIoT and data analytics.

工业领域中相互连接和同步的机器、仪器和其他此类设备的网络被称为工业物联网。智能传感器和执行器集成到工业机器中,以增强工业活动和与业务相关的应用,几乎不需要人工输入。对从这个庞大的机器互联网获得的实时数据进行分析,可以进一步简化工业流程,从而为采用工业物联网框架的企业提供更大的利益。本特别版着重分析大数据分析和工业物联网的相互依存和不可避免的重叠。商业和工业追求经常受到动态需求、不断变化的环境甚至社会政治变化的影响。在当今快速发展的世界中,这些变革的催化剂可能会使企业难以跟上步伐。作为这一问题的解决方案,IIoT通过使用先进的数据分析来积极改变业务成果,有效地促进了智能工业和客户级运营。随着工业物联网的加速发展,我们很快就可以期待数十亿台互联机器以惊人的速度传输前所未有的传感器数据。根据国际数据公司(IDC)的一份报告,2018年全球大数据和分析市场规模达到600亿美元,预计5年复合年增长率将达到12.5%。这种程度的倾斜在很大程度上可以归因于自动化在工业企业中日益增长的重要性。工业物联网网络中设备数量的爆炸式增长,以及由此产生和消耗的数据量的增长,恰如其分地反映了大数据和工业物联网的增长是如何相互受益的。企业在增加收入、降低成本和提高效率方面受益于工业物联网。然而,仅仅生成大量数据并不是最终目标。只有对数据进行适当分析,来自IIoT传感器的数据流才会变得有用。考虑到数据的大量涌入,由于计算能力的限制、网络容量的不足和存储的不足,存储、处理和分析这些数据很容易成为问题。安全问题也对工业物联网和数据分析的融合构成了巨大威胁。安全地处理数据、维护数据并从中提取必要的见解需要一个健壮的安全框架,以防止管理不善和欺诈性使用。成功实施这样一个框架是一个挑战,因为工业物联网背景下的数据分析仍处于起步阶段。工业物联网在工业范式中占据了一席之地,旨在简化、精简和自动化工业活动,以实现最大产出。克服有关高效数据存储、优化数据处理和分析以及有效数据安全的问题对于工业物联网的全面功能至关重要。然而,随着适当技术和算法的应用,数据分析和工业物联网将携手合作,解决工业环境中自动化的挑战。与本版总体主题相关的主题包括但不限于:

A kind of Keller Segel chemotaxis model has a wide range of applications, but its coupling relationship is very complex. The commonly used method of constructing the upper and lower solutions is no longer suitable for the model solution, which results in a long time for its analysis. In this paper, we propose a method to analyze the asymptotic behavior and stability of a Keller Segel chemotaxis model. The previous methods of first formally and then rigorously, the asymptotic expansion of these monotone steady states, and then we use this fine information on the spike to prove its local asymptotic stability. Moreover, we obtain the uniqueness of such steady states. The asymptotic behavior of the solution of a Keller Segel chemotaxis model is analyzed, and the asymptotic rate is calculated; According to the limitation of Neumann boundary condition, the complete blow up of chemotaxis model solution and the stability of the initial value of the complete blow up time are studied, and the asymptotic and stability analysis of a kind of Keller Segel chemotaxis model solution is completed. The experimental results show that the proposed method takes less time to solve a kind of Keller Segel chemotaxis model, improves the efficiency of the solution, and the accuracy of the solution is higher.
一类Keller Segel趋化性模型应用广泛,但其耦合关系非常复杂。常用的构造上解和下解的方法已不适用于模型解,导致分析时间较长。本文提出了一种分析Keller Segel趋化性模型的渐近行为和稳定性的方法。前面的方法先形式化地然后严格地,得到了这些单调稳态的渐近展开式,然后我们利用这些精细信息在尖峰上证明了它的局部渐近稳定性。此外,我们还得到了这种稳态的唯一性。分析了一类Keller Segel趋化模型解的渐近性质,并计算了渐近速率;根据Neumann边界条件的限制,研究了趋化性模型解的完全爆破和完全爆破时间初值的稳定性,完成了一类Keller Segel趋化性模型解的渐近性和稳定性分析。实验结果表明,该方法求解一类Keller Segel趋化性模型所需的时间更短,提高了求解效率,求解精度更高。

Duplication of data in an application will become an expensive factor. These replication of data need to be checked and if it is needed it has to be removed from the dataset as it occupies huge volume of data in the storage space. The cloud is the main source of data storage and all organizations are already started to move their dataset into the cloud since it is cost effective, storage space, data security and data Privacy. In the healthcare sector, storing the duplicated records leads to wrong prediction. Also uploading same files by many users, data storage demand will be occurred. To address those issues, this paper proposes an Optimal Removal of Deduplication (ORD) in heart disease data using hybrid trust based neural network algorithm. In ORD scheme, the Chaotic Whale Optimization (CWO) algorithm is used for trust computation of data using multiple decision metrics. The computed trust values and the nature of the data’s are sequentially applied to the training process by the Mimic Deep Neural Network (MDNN). It classify the data is a duplicate or not. Hence the duplicates files are identified and they were removed from the data storage. Finally, the simulation evaluates to examine the proposed MDNN based model and simulation results show the effectiveness of ORD scheme in terms of data duplication removal. From the simulation result it is found that the model’s accuracy, sensitivity and specificity was good.
应用程序中的重复数据将成为一个昂贵的因素。需要检查这些数据的复制,如果需要,则必须从数据集中删除,因为它占用了存储空间中的大量数据。云是数据存储的主要来源,所有组织都已经开始将他们的数据集迁移到云中,因为它具有成本效益,存储空间,数据安全和数据隐私。在医疗保健领域,存储重复的记录会导致错误的预测。同时很多用户上传相同的文件,会产生数据存储需求。为了解决这些问题,本文提出了一种基于混合信任的神经网络算法的心脏病数据中重复数据删除(ORD)的优化方法。在ORD方案中,采用混沌鲸优化(混沌鲸优化)算法对包含多个决策指标的数据进行信任计算。模拟深度神经网络(Mimic Deep Neural Network, mnn)将计算得到的信任值和数据的性质依次应用到训练过程中。它对数据是否重复进行分类。因此,可以识别重复文件,并从数据存储中删除它们。最后,通过仿真验证了所提出的基于MDNN的模型,仿真结果表明了ORD方案在消除重复数据方面的有效性。仿真结果表明,该模型具有较好的准确性、灵敏度和特异性。

Most methodologies developed to support the Product-Service System (PSS) design consider the integration of service features into the product design from a high-level of abstraction and are usually focused on the conceptual phase, neglecting the detailed level of design. Besides, the Knowledge Management perspective is not considered in those methodologies, also affecting how new design knowledge is created, formalized, and shared across the company’s organization. The PSS Design GuRu Methodology, grounded on Concurrent Engineering and Design for X approaches, was developed to fill these issues. This study presents how the PSS Design GuRu Methodology can be incorporated into a PSS detailed design process in a B2B company operating in the food and bakery machinery sector, focusing the analysis on its contribution to promoting Knowledge Management. In particular, a detailed case of development and integration of a service feature—the installation service—to a product in the PSS scope is conducted. The PSS Design GuRu Methodology proves to be effective in supporting the generation, management, use, sharing, and reuse of new knowledge in the shape of design guidelines and rules.
为支持产品服务系统(PSS)设计而开发的大多数方法都是从抽象的高层考虑将服务功能集成到产品设计中,并且通常侧重于概念阶段,而忽略了设计的详细级别。此外,在这些方法中没有考虑到知识管理的观点,这也影响了如何在公司组织中创建、形式化和共享新的设计知识。PSS设计大师方法论以并行工程和X方法的设计为基础,旨在解决这些问题。本研究介绍了如何将PSS设计大师方法纳入食品和烘焙机械行业B2B公司的PSS详细设计过程,重点分析了其对促进知识管理的贡献。特别地,还详细介绍了将服务特性(安装服务)开发和集成到PSS范围内的产品的案例。PSS设计大师方法论被证明在支持以设计指南和规则的形式生成、管理、使用、共享和重用新知识方面是有效的。

On-tree fruit monitoring is an important practice to provide the exact status of the fruits concerning its quality, quantity and degree of maturity in the farm. In large farm, it is difficult to look over the individual tree manually to acquire the knowledge about the fruits. Again, the manual inspection method is time-consuming, labor intensive and erroneous. The image processing and IoT are the advance techniques applied in diverse field individually. In agriculture sector, image processing is applied for diagnosis of crops. With help of sensors, the IoT based system able to monitor the condition of field remotely. This paper suggests a frame work, which is the combination of image processing and IoT for on-tree fruit monitoring. İn addition, the on-tree counting and size estimation in terms of coefficient of correlation (R2) are 0.994 and 0.997 respectively.
果树上监测是提供果树质量、数量和成熟程度的准确状态的一项重要措施。在大型农场中,很难通过人工查看每棵树来获取有关果实的知识。再次,人工检测方法耗时长,劳动强度大,容易出错。图像处理和物联网是各自应用于各个领域的先进技术。在农业领域,图像处理被应用于农作物的诊断。在传感器的帮助下,基于物联网的系统能够远程监控现场状况。本文提出了一种图像处理与物联网相结合的果树监测框架。İn加上相关系数R2分别为0.994和0.997的树上计数和规模估计。

Paddy is an essential nutrient worldwide. Rice gives 21% of worldwide human per capita energy and 15% of per capita protein. Asia represented 60% of the worldwide populace, about 92% of the world’s rice creation, and 90% of worldwide rice utilization. With the increase in population, the demand for rice is increased. So, the productivity of farming is needed to be enhanced by introducing new technology. Deep learning and IoT are hot topics for research in various fields. This paper suggested a setup comprising deep learning and IoT for monitoring of paddy field remotely. The vgg16 pre-trained network is considered for the identification of paddy leaf diseases and nitrogen status estimation. Here, two strategies are carried out to identify images: transfer learning and deep feature extraction. The deep feature extraction approach is combined with a support vector machine (SVM) to classify images. The transfer learning approach of vgg16 for identifying four types of leaf diseases and prediction of nitrogen status results in 79.86% and 84.88% accuracy. Again, the deep features of Vgg16 and SVM results for identifying four types of leaf diseases and prediction of nitrogen status have achieved an accuracy of 97.31% and 99.02%, respectively. Besides, a framework is suggested for monitoring of paddy field remotely based on IoT and deep learning. The suggested prototype’s superiority is that it controls temperature and humidity like the state-of-the-art and can monitor the additional two aspects, such as detecting nitrogen status and diseases.
稻谷是世界范围内必不可少的营养物质。水稻提供了全世界21%的人均能量和15%的人均蛋白质。亚洲占世界人口的60%,约占世界水稻产量的92%,占世界水稻利用率的90%。随着人口的增加,对大米的需求也增加了。因此,需要通过引进新技术来提高农业生产力。深度学习和物联网是各个领域研究的热点。本文提出了一种基于深度学习和物联网的水田远程监测系统。将vgg16预训练网络用于水稻叶片病害识别和氮素状态估计。本文采用迁移学习和深度特征提取两种策略对图像进行识别。将深度特征提取方法与支持向量机(SVM)相结合进行图像分类。vgg16的迁移学习方法对4种叶片病害的识别和氮素状况的预测准确率分别为79.86%和84.88%。同样,Vgg16的深层特征与SVM结果在4种叶片病害识别和氮素状态预测上的准确率分别达到了97.31%和99.02%。提出了一种基于物联网和深度学习的水田远程监测框架。这款原型机的优势在于,它可以像最先进的产品一样控制温度和湿度,并可以监测另外两个方面,如检测氮状态和疾病。

For over three decades, production firms have extensively espoused lean manufacturing (LM) approach for constantly enhancing their operations. Of late, due to the fusion of physical and digital systems within the Industry 4.0 evolution, production systems can upgrade by applying both notions and lift operational excellence to a new high. This is primarily the reason why digital business transformation has gained significance. Moreover, Industry 4.0 that is led by data assures huge strides in output.

三十多年来,生产企业已经广泛支持精益制造(LM)方法,以不断提高他们的运营。最近,由于工业4.0发展中物理和数字系统的融合,生产系统可以通过应用这两种概念进行升级,并将卓越运营提升到一个新的高度。这是数字化业务转型具有重要意义的主要原因。此外,以数据为主导的工业4.0确保了产量的大幅增长。来自使用服务器、传感器和云计算的生产系统的大量相关数据使得数据交换过程更加庞大和复杂。然而,在工业4.0的背景下,传统系统并不能广泛支持LM。而且,从以往同领域研究者的研究来看,LM中的新技术还没有统一的管理平台。本研究讨论了工业4.0如何将生产转变为一个专注于利用现实世界数据分析的连接机制和平台的行业的相关框架。本文提出的理论框架集成了LM、数据分析和物联网(IoT),以增强流程改进中的决策支持系统。仿真中的数据分析是通过物联网来实现的,通过维护LM的原理来改善瓶颈问题。详细展示了LM决策支持系统中的主要信息流路径,以展示决策过程是如何完成的。决策支持机制经历了升级,所建议的框架表明同化的组件可以共同作用以增加输出。

In the conceptual design phase of eco-products, the evaluation of products eco-design is often considered by designers after determining the design scheme. In order to improve the eco-design efficiency, a CAD-based feedback knowledge push method was proposed to meet the designer’s eco-design knowledge requirements. Combine with the designer knowledge background, classified eco-design knowledge, and decomposed design tasks, eco-design knowledge requirements of designers can be obtained. Based on the cosine similarity algorithm of the knowledge vector space model (VSM), the knowledge requirements of the designer and the knowledge in the knowledge database are matched, and the eco-knowledge is actively pushed to the designer. The feedback and evaluation of designers on the initial push of knowledge was recorded by the system. When the designer is assigned relevant eco-design tasks again, the system conducts secondary filtering of eco-design knowledge through previous feedback records and pushes the filtered knowledge to designers, so as to achieve accurate feedback knowledge push. A CAD-based eco-design knowledge push prototype system for automotive products is developed. The eco-design of the front-end module of the automotive is used as an example to verify the effectiveness of the above method.
在生态产品的概念设计阶段,设计师在确定设计方案后往往会考虑产品生态设计的评价。为了提高生态设计效率,提出了一种基于cad的知识反馈推送方法,以满足设计者对生态设计知识的需求。结合设计师的知识背景,对生态设计知识进行分类,对设计任务进行分解,得出设计师的生态设计知识需求。基于知识向量空间模型(VSM)的余弦相似度算法,将设计者的知识需求与知识库中的知识进行匹配,并将生态知识主动推送给设计者。系统记录了设计师对知识初始推送的反馈和评价。当设计师再次被分配相关的生态设计任务时,系统通过之前的反馈记录对生态设计知识进行二次过滤,并将过滤后的知识推送给设计师,实现准确的反馈知识推送。开发了基于cad的汽车产品生态设计知识推送原型系统。以汽车前端模块的生态设计为例,验证了上述方法的有效性。

Due to the current and highly competitive industrial scenario, the technology-oriented organizations have been making routine adjustments to the conventional IPDP, in order to seek more profitable business models. Identifying the product functions, as well as its importance - perceived by the consumer - and being able to associate this information with manufacturability and assembly aspects, is fundamental to achieve more competitive, low-cost and higher quality products. This article objective is to evaluate this method concept, applying it in an industrial project. In order to assess the method within the complete integrated product development process (IPDP), the activities related to the conceptual and preliminary phases of the project delineated this article limits. This study selected a subgroup of the white goods industry, where first the traditional models of VE were applied in the conceptual design phase. Subsequently, the classic DFA models were applied in the preliminary design phase. Thus, it was possible to apply the proposed iterative method, where the alternatives generated with the DFA were cyclically re-evaluated, function by function, in the previous stage of value analysis. With this, this study came to the method assessment, its gains and limitations. Then, the original design was compared with the solution after the proposal application, without the method used. Finally, this study verified the influence of the method on the balance between the value and the cost of each function, in addition to the direct comparison of the solution final cost with the version without the method application. Among the results, this article presents a report showing the method viability, its particularities, impacts, and limitations.
由于当前竞争激烈的工业环境,技术型组织一直在对传统的IPDP进行常规调整,以寻求更有利可图的商业模式。确定产品功能及其重要性- -由消费者感知- -并能够将这些信息与可制造性和装配方面联系起来,是实现更具竞争力、低成本和高质量产品的根本。本文的目的是评估该方法的概念,并将其应用于一个工业项目。为了在完整的集成产品开发过程(IPDP)中评估该方法,本文限定了与项目的概念和初步阶段相关的活动。本研究选择了白色家电行业的一个子组,其中首先在概念设计阶段应用了VE的传统模型。随后,将经典DFA模型应用于初步设计阶段。因此,有可能应用所提出的迭代方法,其中DFA生成的备选方案在价值分析的前一阶段逐函数循环重新评估。在此基础上,本研究对该方法进行了评价,分析了其优缺点。然后,将原始设计与提案应用后的解决方案进行比较,不使用所使用的方法。最后,本研究除了将解决方案的最终成本与未应用该方法的版本进行直接比较外,还验证了该方法对各功能的价值和成本之间平衡的影响。在结果中,本文提出了一份报告,显示了该方法的可行性、特殊性、影响和局限性。

Today, three conditions are crucial for a company to be competitive on the market: quality, reduced time and low costs for the development of new products. The paper shows how companies developing new products (NPD) for the market can successfully implement concurrent engineering as an improvement of project management, in order to reduce product development time and costs and to ensure the quality expected by customers. The methodology presented in this paper is based on three main pillars of knowledge: project management, teamwork and concurrent engineering. The methodology provides a step-by-step guideline for the introduction of concurrent engineering in a company. This paper also presents the results of 10 Slovenian companies where this methodology has been tested on 20 pilot projects. The results show that managed projects upgraded with the principles of concurrent engineering lead to cost reduction, shorter development time and fewer discrepancies.
