An Approach to Evaluate the Implementation Effects of Advanced Manufacturing Technology Based on the Specialists' Opinion Selection

Since domestic corporations firstly introduced into and implemented the Advanced Manufacturing Technology (AMT),how to scientifically evaluate the implementation effects of AMT has been an urgent problem.Through the review of for- eign relative studies,this paper constructs an indicator system used to evaluate the implementation effects of AMT.Operational performance,Organizational or managerial performance,Satisfactory performance,and Competitive performance are indicators of first level in the system,and 19 indicators of second level have been selected to estimate the implementation effects of AMT.In this study,a model based on Minkowski distance discriminance to select the specialists’ opinion was designed to evaluate the indica- tor system,and the measure’s validity and practicability was proved by a case study to a diesel engine factory.

Effects of Job Characteristics on Performance of Advanced Manufacturing Technology:an Empirical Examination to Equipment-manufacturing Industry

Advanced manufacturing technology(AMT)is pivotal for firms to gain manufacturing performance and com- petitive advantage.Job characteristics,as a kind of important factors affecting the implementation effects of AMT ,have become the focus in the field of academy.Based on a literature review,this study refines the implementation effects of AMT into opera- tional performance,satisfaction and competitive performance,and reclassifies the job characteristics of AMT into job autonomy, job responsibility,job complexity and job significance.With a large sample of 307 equipment-manufacturing firms selected from the 2005 China International Equipment and Manufacturing Exposition,linear structural equation analysis(LIEREL)is per- formed to examine the relationships between job characteristics and the implementation effects of AMT.The results show that job re- sponsibility and job significance have positive effects on satisfaction;satisfaction is positively correlated with operational perfor- mance;operational performance positively affects competitive performance.The findings provide the guide for firms to improve satisfaction,achieve higher operational performance and further gain higher competitive by reasonable job redesign.

A Mini-Review and Perspective on Current Best Practice and Emerging Industry 4.0 Methods for Risk Reduction in Advanced Composites Manufacturing

The manufacturing of composite structures is a highly complex task with inevitable risks, particularly associated with aleatoric and epistemic uncertainty of both the materials and processes, as well as the need for in-situ decision-making to mitigate defects during manufacturing. In the context of aerospace composites production in particular, there is a heightened impetus to address and reduce this risk. Current qualification and substantiation frameworks within the aerospace industry define tractable methods for risk reduction. In parallel, Industry 4.0 is an emerging set of technologies and tools that can enable better decision-making towards risk reduction, supported by data-driven models. It offers new paradigms for manufacturers, by virtue of enabling in-situ decisions for optimizing the process as a dynamic system. However, the static nature of current (pre-Industry 4.0) best-practice frameworks may be viewed as at odds with this emerging novel approach. In addition, many of the predictive tools leveraged in an Industry 4.0 system are black-box in nature, which presents other concerns of tractability, interpretability and ultimately risk. This article presents a perspective on the current state-of-the-art in the aerospace composites industry focusing on risk reduction in the autoclave processing, as an example system, while reviewing current trends and needs towards a Composites 4.0 future.

交流冷金属过渡(Advanced CMT)技术的研究进展及其在增材制造中的应用

电弧增材制造技术是低成本金属零件快速成形的重要方法之一,零件的成形精度目前因电弧热输入量过高而无法精确控制,国内外使用冷金属过渡技术进行增材制造成为热点。交流冷金属过渡技术(Advanced CMT)既秉承了原冷金属过渡技术(CMT)无飞溅、焊速快、热输入量低的特点,又引入变极性的交流电模式,使焊接过程中的热量分布更合理,基材收到的热输入量进一步降低。通过对CMT技术和交流CMT技术的研究现状进行比较和分析,认为交流CMT技术以其更低的热输入量,更高的熔敷效率和焊接稳定性等优势而更适合应用于增材制造领域,并且下一步应该侧重于解决交流CMT技术下的凝固过程原位检测表征,以及热源模拟的进一步修正,为复杂件的精确成形奠定基础。

Digital Transformation of Small and Medium Sized Enterprises Production Manufacturing

Industry 4.0 concepts have brought about a wind of renewal in the organization of companies and their production methods. However, this integration is subject to obstacles when it comes to Small and Medium sized Enterprises—SMEs: the costs of new technologies to be acquired, the level of maturity of the company regarding its level of digitization and automation, human aspects such as training employees to master new technologies, reluctance to change, etc. This article provides a new framework and presents an intelligent support system to facilitate the digital transformation of SMEs. The digitalization is realized through physical, informational, and decisional points of view. To achieve the complete transformation of the company, the framework combines the triptych of performance criteria (cost, quality, time) with the notions of sustainability (with respect to social, societal, and environmental aspects) and digitization through tools to be integrated into the company’s processes. The new framework encompasses the formalisms developed in the literature on Industry 4.0 concepts, information systems and organizational methods as well as a global structure to support and assist operators in managing their operations. In the form of a web application, it will exploit reliable data obtained through information systems such as Enterprise Resources Planning—ERP, Manufacturing Execution System—MES, or Warehouse Management System—WMS and new technologies such as artificial intelligence (deep learning, multi-agent systems, expert systems), big data, Internet of things (IoT) that communicate with each other to assist operators during production processes. To illustrate and validate the concepts and developed tools, use cases of an electronic manufacturing SME have been solved with these concepts and tools, in order to succeed in this company’s digital transformation. Thus, a reference model of the electronics manufacturing companies is being developed for facilitating the future digital transformation of these domain companies. The realization of these use cases and the new reference model are growing up and their future exploitation will be presented as soon as possible.

The Future of Manufacturing： A New Perspective

关于智能制造,前人已发表了很多文章。其大多数内容都集中在硬件、软件、增材制造、机器人、物联网(Internet of Thing,IoT)以及工业4.0等话题,而对另一些极重要的领域却少有讨论,如混合系统、先进制造业重定义、新制造的基本构成元素、制造业生态系统准备水平及技术可扩展性等。本文将通过实例,从全新的视角,为读者剖析这些领域中目前的四个挑战。挑战一:当我们希望提高公众对新制造业经济及其社会影响的认识水平,并获得政策制定者的明确支持时,应如何重新定义未来制造业。挑战二:如何正确认识到未来制造业的关键词是"混合"。它具有人类与机器人协作、增材制造与减材制造结合、金属材料与复合材料并用以及网络系统与物理系统融合等特点。因此,划定界限与制定标准变得尤其重要。挑战三:如何开发一个同时对技术、制造商业化和新制造生态系统做出评估的通用框架,以缩短生产到交付之间的时间;以及在该框架下,如何进一步制定一套可被广泛采用的、针对非信息技术的可扩增性测量的标准。最后,也是同样重要的是挑战四:如何通过公司多方合作,来验证"产-学-政"三位一体的模型是否成功。本文将详细讨论上述四大挑战。

我国先进制造业与生产性服务业融合生态位研究

基于2012-2021年省级面板数据,运用生态位模型测度先进制造业与生产性服务业融合差异与竞争现状。结果表明:先进制造业与生产性服务业融合生态位宽度空间上呈现东高西低分布特征,其中融合基础生态位宽度两极分化极其严重是导致我国生态位宽度呈梯度分布的主要原因。生态位重叠现象普遍,区域间存在激烈竞争,其中地理位置和优势主导产业相近更易形成相同的融合路线,导致重叠度较高。生态位适宜度整体水平偏低,融合子系统生态位适宜度均呈现“东高、中平、西低”特征。
