Quality function deployment (QFD) is a systematic approach to transform customer requirements (CRs) into product engineering characteristics (ECs). Traditional QFD relies on market research or customer questionnaires to collect a series of ambiguous and uncertain CRs. As a result, evaluating the weighting of CRs and determining the design matrix between CRs and ECs have become the focus and difficulty of QFD. This paper proposes the grey system theory in artificial intelligence technology combined with QFD to develop grey-QFD to solve the issues mentioned before. First, collect the average evaluation values between the aesthetic images and customer satisfaction of representative products. The grey prediction GM (1, N) model is used to obtain the weight of aesthetic needs relative to customer satisfaction and import it into the left QFD. Second, the domain experts decomposed the product form into a morphological analysis table, and fuzzy Delphi screened key ECs and imported them into the ceiling of QFD. Finally, grey relationship analysis established the aesthetic product design matrix between CRs and ECs, and calculated and ranked the final weights of each ECs by using grey relationship degree. The research uses the security camera in the smart home as an experimental object. After operating the proposed grey-QFD, the aesthetic quality of the target product (lively, intelligent, friendly, personalized, and fashionable) and the optimization of the corresponding product ECs are obtained. The result provides a theoretical reference for designers and significantly improves customer aesthetic satisfaction.
质量功能展开(QFD)是一种将顾客需求(cr)转化为产品工程特征(ECs)的系统方法。传统的QFD依靠市场调查或客户问卷来收集一系列模棱两可和不确定的cr。因此,评价质量评价指标的权重,确定质量评价指标与质量评价指标之间的设计矩阵,成为质量评价指标设计的重点和难点。本文提出将人工智能技术中的灰色系统理论与QFD相结合,发展灰色QFD来解决上述问题。首先,收集代表产品的审美形象与顾客满意度之间的平均评价值。利用灰色预测GM (1, N)模型得到审美需求相对于顾客满意度的权重,并将其导入左侧的QFD。其次,由领域专家将产品形态分解成形态分析表,通过模糊德尔菲法筛选出关键的ECs,导入到QFD的天花板中;最后,通过灰色关联度分析,建立评价中心与评价中心之间的美学产品设计矩阵,利用灰色关联度对评价中心的最终权重进行计算和排序。本研究以智能家居中的安防摄像头作为实验对象。通过对所提出的灰色qfd进行操作,得到目标产品的审美品质(活泼、智能、友好、个性化、时尚)和相应产品ECs的优化。研究结果为设计师提供了理论参考,显著提高了顾客的审美满意度。

The optimization of production planning and scheduling is important for modern process industry. Due to different time dimensions of them, it is easy to create conflicts between the optimization results if they are solved separately, and the final results are not feasible. When facing a complex problem like production model, Collaborative optimization could be applied, but it still has shortcomings. Therefore, the improvement of collaborative optimization is proposed and improved collaborative optimization is applied to solve the uncertain production model. At last, the simulation results show that improved collaborative optimization can achieve better global optimization capability and practicability. This paper not only shows that the application scope of collaborative optimization has been expanded, but also provides a new idea for solving the uncertain production model.
生产计划与调度的优化是现代过程工业的重要问题。由于它们的时间维度不同,如果单独求解,容易造成优化结果之间的冲突,最终结果不可行。当面对生产模型这样的复杂问题时,协同优化是可以应用的,但它仍然存在不足。为此,提出了改进的协同优化方法,并将改进的协同优化方法应用于求解不确定生产模型。仿真结果表明,改进后的协同优化方法具有更好的全局优化能力和实用性。本文不仅拓展了协同优化的应用范围,而且为求解不确定生产模型提供了一种新的思路。

With the popularity of IoT (Internet of Things) technology, more and more engineering systems are integrated with context-aware functionalities. It is self-evident that functional analysis is a critical process for successful development of such context-aware systems (CASs). Since existing functional analysis approaches are primarily for developing traditional engineering systems, this paper aims at developing a structured approach for assisting engineers in carrying out functional analysis of CASs. Based on the concept of context from an interactive perspective, this research analyzes what constitutes the context of a CAS and its basic features. Then a structured approach for functional analysis is proposed, which systematically elaborates how to define and analyze the context of a CAS, how to identify functionalities from the context, and how to develop the functional structure of a CAS. A case study of the functional analysis of a self-service checkout system is employed to demonstrate the proposed approach, which shows that the proposed approach can help designers carry out functional analysis of CASs in an effective manner.
随着物联网(IoT)技术的普及,越来越多的工程系统集成了上下文感知功能。不言而喻,功能分析是成功开发这种上下文感知系统(CASs)的关键过程。由于现有的功能分析方法主要用于开发传统的工程系统,因此本文旨在开发一种结构化的方法来协助工程师进行CASs的功能分析。本文从互动视角出发,以语境概念为基础,分析了CAS语境的构成及其基本特征。然后提出了一种结构化的功能分析方法,系统阐述了如何定义和分析CAS的上下文,如何从上下文中识别功能,以及如何构建CAS的功能结构。以自助结账系统的功能分析为例,对本文提出的方法进行了验证,结果表明,本文提出的方法能够有效地帮助设计人员对CASs进行功能分析。

With the improvement of manufacturing technology, the performance gap between different products has been gradually narrowed, and customers pay more and more attention to psychological feelings and aesthetic experiences in the process of purchasing and using products. Therefore, the main purpose of this research is to construct a hybrid model of aesthetic product design to develop customer satisfaction. Firstly, seven customer aesthetic needs are summarized by discussing the literature. The Kansei evaluation and customer satisfaction evaluation are investigated using Likert-scale, and the neural network is repeatedly trained and tested to obtain the weight of each aesthetic requirement. Secondly, the morphological analysis method is used to obtain the product morphological deconstruction table, and the entropy method is used to calculate the initial weights of the engineering characteristics (ECs). Finally, quality function development (QFD) is used as the platform to construct the relationship matrix between customer aesthetic needs and product ECs. Grey relationship analysis is used to calculate the final weight of ECs and obtain the priority of ECs. The research takes the side view of a car as a case. The results show that the best product form combination can provide a reference for designers and effectively improve the aesthetic experience and customer satisfaction of the product.
随着制造技术的提高,不同产品之间的性能差距逐渐缩小,顾客在购买和使用产品的过程中越来越注重心理感受和审美体验。因此,本研究的主要目的是构建一个审美产品设计的混合模型,以发展顾客满意度。首先,通过文献讨论,总结出顾客的七种审美需求。使用李克特量表对感性评价和顾客满意度评价进行研究,并对神经网络进行反复训练和测试,以获得每个审美要求的权重。其次,采用形态分析法获得产品形态解构表,并采用熵值法计算工程特征初始权值;最后,以质量功能开发(QFD)为平台,构建顾客审美需求与产品ECs之间的关系矩阵。采用灰色关联度分析方法,计算出评价指标的最终权重,确定评价指标的优先级。本研究以汽车的侧面为例。结果表明,最佳的产品形态组合可以为设计师提供参考,有效地提高产品的审美体验和顾客满意度。

One of the major challenges in variety management of modular product families is to prevent continuously generated variants of design elements. This paper aims to provide guidance on how manufacturing companies can reduce a large number of variants that have already increased from the existing product architectures. This paper introduces a new concept of architecture named variation architecture ( VA) in which relationships between variants in the market, design, and production domains are arranged explicitly for planning variety of a modular product family. Since the VA includes two perspectives which are domain mapping and variant-level planning, it can help companies to systematically establish complex relationships between variants across the domains. This paper describes elements of the three domains, relationship types between elements, and four categories of relationship rules called management rules at the variant-level planning. A framework is proposed for reducing variants through the VA to demonstrate its applicability. In the case study, we apply the framework to a front chassis family having a large number of variants and show that the VA significantly reduces unnecessary variants compared to the currently being produced.
模块化产品族的品种管理面临的主要挑战之一是防止设计元素不断产生变体。本文旨在为制造公司如何减少已经从现有产品架构中增加的大量变体提供指导。本文介绍了一种新的体系结构概念,即变型体系结构(VA)。在变型体系结构中,市场、设计和生产领域的变型之间的关系被明确地安排,以规划模块化产品族的变型。由于VA包含两个透视图,即域映射和变量级规划,它可以帮助公司系统地建立跨域的变量之间的复杂关系。本文描述了三个领域的元素、元素之间的关系类型以及变体级规划中称为管理规则的四类关系规则。提出了一种通过VA减少变量的框架,以证明其适用性。在案例研究中,我们将该框架应用于具有大量变体的前底盘系列,并表明与目前正在生产的变体相比,VA显着减少了不必要的变体。

In a highly competitive market environment, organizations must improve their productivity, reduce production costs and improve management methods, in order to maintain a favorable competitive position. Project factors, such as time, cost and risk are closely linked. If one of those factors is out of control, the progress of the whole project will inevitably be delayed. When the progress of the project is delayed, duration compression measures such as crashing or fast tracking are usually employed to ensure the backward schedule returns to the original plan. However, the implementation of duration compression measures increases the cost and risk of the project. In most previous study of the critical path, only activity time is involved, and cost and risk are not considered. In the present study, a mathematical model is built to solve the optimal duration compression scheme objectives of the minimization of risk and cost. The model is verified by two cases, and the best solution is obtained by using LINGO software and Excel solver. The mathematical model is found to provide the best duration compression scheme for the project, with the least increases in cost and risk.
在竞争激烈的市场环境中,组织必须提高生产力,降低生产成本,改进管理方法,才能保持有利的竞争地位。项目因素,如时间、成本和风险是紧密相连的。如果其中一个因素失控,整个项目的进度将不可避免地受到影响。当项目进度延迟时,通常采用工期压缩措施,如崩溃或快速跟踪,以确保向后的进度恢复到原计划。然而,工期压缩措施的实施增加了项目的成本和风险。在以往的关键路径研究中,大多只考虑活动时间,没有考虑成本和风险。本文建立了以风险和成本最小为目标的最优工期压缩方案的数学模型。通过两个算例对模型进行了验证,并利用LINGO软件和Excel求解器得到了最优解。该数学模型为工程提供了最佳工期压缩方案,成本和风险的增加最小。

In recent years, there has been a significant increase in the adaptation of current computer methodologies to tackle issues from different fields. Education, medical research, and agriculture are just a few of the fields that have seen fast development as a result of the rapid advancements in contemporary computer technology. These advancements may be seen in the form of more complex technology as well as enhanced algorithms for data processing. One such advancement is the Internet of Things (IoT)-based computing. Smart agricultural processes are being built with the use of Internet of Things (IoT) device-oriented solutions, which are becoming more popular. Nonetheless, the application of IoT devices to tackle these issues across a wide range of fields is fraught with a number of difficulties. The primary challenges are the high cost of deployment, the capacity or sustainability of the deployed device sets due to the limitations of battery technology, and, finally, the maintainability of these devices remotely due to the lack of an adequate communication infrastructure for IoT devices, all of which are significant obstacles. In particular, the adaption of Internet of Things solutions for agriculture has these previously discussed issues to a higher extent. In recent years, a slew of parallel research outputs has emerged, all of which are geared at finding solutions to these issues. Nonetheless, these parallel study outputs or current remedies have been criticized for not addressing all of the issues, but rather for focusing on just one of the three issues that have been identified as problematic. Thus, this study indicates the need, and possibility for developing a framework that may be used to address all of the challenges that have been identified. To begin, the recommended method, which is proven in the work, provides an automated procedure to assess the farm field, and then proposes the most ideal design for placing the Internet of Things devices. This study exhibits a unique application of the curve fitting approach for range, and power awareness, as well as a novel deployment of an optimization method for range, and power awareness, in order to determine the most optimum, and cost-effective deployment map or plan. Second, this study provides a technique for collecting sensor data in the most efficient manner possible, allowing any analytical engine to be constructed on top of the suggested architecture. According to the suggested framework, response time has been reduced by 15%, and average churn rates have been reduced by almost 20% when compared to the results of parallel research, resulting in increased network sustainability when compared to the results of parallel research results.
近年来,在处理来自不同领域的问题时,对当前计算机方法的适应有了显著的增加。教育、医学研究和农业只是由于当代计算机技术的快速发展而得到快速发展的几个领域。这些进步可能以更复杂的技术以及增强的数据处理算法的形式出现。其中一个进步是基于物联网(IoT)的计算。智能农业流程正在使用物联网(IoT)设备导向的解决方案来构建,这些解决方案正变得越来越流行。尽管如此,在广泛的领域应用物联网设备来解决这些问题充满了许多困难。主要的挑战是部署成本高,由于电池技术的限制而部署的设备集的容量或可持续性,最后,由于缺乏足够的物联网设备通信基础设施,这些设备的远程可维护性,所有这些都是重大障碍。特别是物联网解决方案在农业领域的应用,在更高程度上解决了上述问题。近年来,出现了一系列平行的研究成果,都是为了寻找这些问题的解决方案。尽管如此,这些平行的研究成果或目前的补救措施被批评为没有解决所有问题,而是只关注已确定的三个问题中的一个。因此,这项研究表明了开发一个框架的必要性和可能性,该框架可用于解决已确定的所有挑战。首先,推荐的方法在工作中得到了验证,它提供了一个自动化的程序来评估农场,然后提出放置物联网设备的最理想设计。本研究展示了对距离和功率感知曲线拟合方法的独特应用,以及对距离和功率感知优化方法的新颖部署,以确定最优和最具成本效益的部署地图或计划。其次,本研究提供了一种以最有效的方式收集传感器数据的技术,允许在建议的架构之上构建任何分析引擎。根据建议的框架,与并行研究结果相比,响应时间减少了15%,平均流失率减少了近20%,与并行研究结果相比,网络的可持续性得到了提高。

Education, medical research, and agriculture are just a few of the fields that have seen fast development as a result of the rapid advancements in contemporary computer technology. These advancements may be seen in the form of more complex technology as well as enhanced algorithms for data processing. One such advancement is the Internet of Things (IoT)-based computing. Smart agricultural processes are being built with the use of Internet of Things (IoT) device-oriented solutions, which are becoming more popular. Nonetheless, the application of IoT devices to tackle these issues across a wide range of fields is fraught with a number of difficulties. The primary challenges are the high cost of deployment, the capacity or sustainability of the deployed device sets due to the limitations of battery technology, and, finally, the maintainability of these devices remotely due to the lack of an adequate communication infrastructure for IoT devices, all of which are significant obstacles. In particular, the adaption of Internet of Things solutions for agriculture has these previously discussed issues to a higher extent. In recent years, a slew of parallel research outputs has emerged, all of which are geared at finding solutions to these issues. Nonetheless, these parallel study outputs or current remedies have been criticized for not addressing all of the issues, but rather for focusing on just one of the three issues that have been identified as problematic. Thus, this study indicates the need, and possibility for developing a framework that may be used to address all of the challenges that have been identified. To begin, the recommended method, which is proven in the work, provides an automated procedure to assess the farm field, and then proposes the most ideal design for placing the Internet of Things devices. This study exhibits a unique application of the curve fitting approach for range, and power awareness, as well as a novel deployment of an optimization method for range, and power awareness, in order to determine the most optimum, and cost-effective deployment map or plan. Second, this study provides a technique for collecting sensor data in the most efficient manner possible, allowing any analytical engine to be constructed on top of the suggested architecture.

This research investigates the novel techniques which provide the detailed information on the biometric images used along with the methods applied for biometric image pre-processing. It also describes the proposed methodology which was implemented with the method of optimized Particle Swarm Optimization (PSO) with Artificial Neural Network (ANN) algorithm for classification of attributes. In the current work, a big effort has been implemented for designing an efficient technique for recognizing the biometric images, especially for the modalities like finger print and retina image. Initially, the pre-processing module used the method of histogram equalization to enhance the contrasts of entire image in order to get the best image quality. This makes the image adaptable for further processing. Next, the feature extraction module has the involvement of two image sets (finger print and retina image). The Gray Level Co-occurrence Matrix (GLCM) was used for extracting the needed features in this module. Next is Feature Based Fusion Technique (FBFT) for reducing the features for authentication purpose. This research work uses the FBFT to get fused feature vector. Finally, deals with the non-recognition and recognition of the images. The images were tested by using Artificial Neural Network (ANN). Here, the recognition is done by ANN and the optimization is done by the sophisticated function of Particle Swarm Optimization Algorithm (PSOA). ANN does the classification of images as recognized and non-recognized and yields best results.
本研究探讨了提供生物特征图像详细信息的新技术,以及应用于生物特征图像预处理的方法。提出了一种基于优化粒子群算法(PSO)和人工神经网络(ANN)的属性分类方法。在目前的工作中,人们一直在努力设计一种高效的生物特征图像识别技术,特别是指纹和视网膜图像的识别技术。首先,预处理模块采用直方图均衡化的方法对整个图像进行对比度增强,以获得最佳的图像质量。这使得图像能够适应进一步的处理。接下来,特征提取模块涉及两个图像集(指纹和视网膜图像)。该模块采用灰度共生矩阵(GLCM)提取所需特征。其次是基于特征的融合技术(FBFT),用于减少用于身份验证的特征。本研究利用FBFT得到融合特征向量。最后,讨论了图像的非识别和识别问题。利用人工神经网络(ANN)对图像进行检测。其中,识别由人工神经网络完成,优化由粒子群优化算法(PSOA)完成。人工神经网络将图像分类为可识别和不可识别,并产生最佳结果。

In recent years, more than 50 million people have been affected by the epilepsy, neurological disorder diseases. To monitor the situation of the epilepsy patient requires experienced and skilled person. In order to overcome these issues, autonomous detection of electroencephalogram (EEG) signal by deep learning model has evolved. Convolutional neural network (CNN) is one of the sub-category of neural network and widely used in the various field such as weather forecasting, signal processing and medical applications. In this article, the University of California Irvine (UCI) respiratory EEG signals are used to analyse the proposed hybrid CNN and results are compared to the pre-trained GoogleNet Network. EEG signals are initially converted into three different forms such as scalogram, spectrogram and time domain images and classification of images are carried out by the pre-trained GoogleNet network results in an accuracy of 85%. Then time domain images are combined with spectrogram and scalogram EEG signal separately and detection has been carried out by the CNN. It is found that the CNN network yields an accuracy of 92% which was higher than the pre-trained GoogleNet. To enhance the classification accuracy further, scalogram, spectrogram and time domain images are combined as single input images and applied to the CNN network and it results with the accuracy of 98%. The performance metrics such as Sensitivity, Specificity, F1 Score, Precision and misclassification rate of GoogleNet and proposed hybrid CNN networks are evaluated. It is observed from the result that proposed CNN results less than 10% misclassification rate, whereas for GoogleNet it was more than 20%. Similarly, the precision value of GoogleNet and proposed CNN networks are 82% and 93%, respectively.
近年来,有超过5000万人受到癫痫等神经紊乱疾病的影响。监测癫痫患者的情况需要有经验和熟练的人员。为了克服这些问题,发展了基于深度学习的脑电图信号自主检测模型。卷积神经网络(Convolutional neural network, CNN)是神经网络的一个分支,广泛应用于天气预报、信号处理、医疗等各个领域。在本文中,使用加州大学欧文分校(UCI)的呼吸EEG信号来分析所提出的混合CNN,并将结果与预训练的GoogleNet网络进行比较。首先将脑电信号转换成尺度图、频谱图和时域图像三种不同的形式,利用预先训练好的GoogleNet网络对图像进行分类,准确率达到85%。然后将时域图像分别与脑电信号的谱图和尺度图相结合,利用CNN进行检测。研究发现,CNN网络的准确率为92%,高于预训练的GoogleNet。为了进一步提高分类精度,将尺度图、谱图和时域图像合并为单输入图像,应用到CNN网络中,准确率达到98%。对GoogleNet和混合CNN网络的灵敏度、特异性、F1评分、精度和误分类率等性能指标进行了评估。从结果中可以观察到,提出的CNN结果的误分类率小于10%,而GoogleNet的误分类率大于20%。同样,GoogleNet和提出的CNN网络的精度值分别为82%和93%。
