Abstract:

In recent years, many design approaches have been developed for automated manufacturing systems in the fields of reconfigurable manufacturing systems (RMSs), holonic manufacturing systems (HMSs), and multi-agent systems (MASs). One of the principle reasons for these developments has been to enhance the reconfigurability of a manufacturing system, allowing it to adapt readily to changes over time. However, to date, reconfigurability assessment has been limited. Hence, the efficacy of these design approaches remains inconclusive. This paper is the first of two in this issue to address reconfigurability measurement. Specifically, it seeks to address ‘reconfiguration potential’ by analogy. Mechanical degrees of freedom have been used in the field of mechanics as a means of determining the independent directions of motion of a mechanical system. By analogy, manufacturing degrees of freedom can be used to determine independent ways of production. Furthermore, manufacturing degrees of freedom can be classified into their production and product varieties. This paper specifically focuses on the former to measure the product-independent aspects of manufacturing system ‘reconfiguration potential’. This approach will be added to complementary work on the measurement of ‘reconfiguration ease’ so as to form an integrated reconfigurability measurement process described elsewhere [1—5].

Abstract:

This article analyses the reasons and impact of shift of manufacturing startups from the United States to overseas. After years of refining prototypes and perfecting pilot plants, advanced manufacturing startups frequently look overseas when it is time to scale-up for commercial production. Both manufacturing and technology companies go abroad looking for partnerships, because it is easier for investors. When startups scale their manufacturing elsewhere, the United States loses more than a possible return on the research investment that made such breakthroughs possible. The preliminary research suggests that to fully realize the economic gains associated with innovation, new products and services developed by American innovators must be scaled-up within the US economy, as well as in overseas markets. The four suggestions that have been made include the following: increase financing options for later-stage development; create institutions and incentives; change the contours of market demand; and encourage firms to raise capital through initial public offerings.

Abstract:

Information-theory has been used to research the manufacturing system complexity for decade years. In order to describe the complexity more accurately, the assembly manufacturing system is aimed in this paper. The hierarchy structure of the assembly manufacturing system is first analyzed. The assembly system complexity is classified as structure complexity, process complexity and control complexity. In order to improve the complexity model, the process complexity is furthermore classified as static and dynamic process complexity which can describe the complexity of ideal and actual production process respectively. Then an integrated complexity model is proposed based on the classification.

This paper is the second of two in this issue to address reconfigurability measurement. Specifically, ‘reconfiguration ease’ has often been qualitatively argued to depend on the system's modularity. For this purpose, this paper develops modularity measures in a three-step approach. Firstly, the nature of typical manufacturing system interfaces is discussed. Next, the qualitative understanding underlying existing modularity measures is distilled. Finally, these understandings are synthesized for a manufacturing system context. This approach forms the second of two pillars that together lay the foundation for an integrated reconfigurability measurement process described elsewhere.

Abstract:

The findings of two UK government funded studies are reviewed which have highlighted requirements of next generation manufacturing systems. The studies have (a) generated a view of alternative futures for manufacturing enterprises and (b) identified barriers to their realization. This illustrates an important future role for holistic model driven manufacturing systems, which respond rapidly to competitive forces and sociopolitical economic change while maintaining good alignment between business goals and related processes and operations. The findings help to identify requirements of next generation enterprise integration methods, architectural frameworks, reference models, integration mechanisms and component elements. Based on this requirement definition the capabilities of emerging and proprietary enterprise integration methods and tools have been assessed and classified.

Full text

Abstract:

Underwater vocalisations of grey seals (Halichoerus grypus) were recorded by static acoustic monitoring (SM2M, Wildlife Acoustics) in the vicinity of a colony located at White Strand beach on Great Blasket Island, southwest Ireland during the pre-breeding and breeding seasons. Grey seal vocalisations were first classified across nine different categories based on aural and visual characteristics of the spectrograms, providing an acoustic repertoire for grey seals. This classification was further investigated by applying a classification tree analysis, resulting in five of the initial nine groups being selected. Furthermore, a comparison of two common approaches for the detection and extraction of vocalisations from acoustic files was done using the software Raven Pro and PAMGuard. The outputs of this study will present an essential first step towards the development of a protocol for underwater acoustic monitoring of grey seals in Irish waters and elsewhere.

Abstract:

Purpose The purpose of this paper is to study the integration between fused deposition modeling (FDM) technology and abrasive flow machining process to improve the surface quality of FDM printed parts. FDM process has some limitations in terms of accuracy and surface finish. Hence, post-processing operations are essential to increase the quality of the part. Design/methodology/approach Initially, a sustainable polymer abrasive gel-based media (SPAGM) using natural polymer and natural additives (waste vegetable oil) was prepared using different combinations of (abrasive mesh size, percentage of abrasives and percentage of liquid synthesizer); then the characterization of media was done to check various properties. As media is an essential part in the process which helps in increase the surface finish, it needs to have some desired characteristics such as the following: the developed SPAG needs to hold the abrasives; its viscosity has to be medium so that it can easily flow through the machine; and its thermal stability caused by the increase in the temperature during various cycles of operation. For that, it is characterized rheologically as well as thermally to find its various properties. Findings Experiments were performed on FDM-printed parts using an L9 orthogonal array with different parameters to find their effect on the workpiece. Scanning electron microscope images of SGAPM showed sharp edges of abrasive particles and bonding pattern between polymer chain molecules. Good surface finish and material removal rate (MRR) was observed at high pressure and long finishing time with 50 per cent abrasive concentration. Originality/value The authors confirm that this work is original and has neither been published elsewhere nor is it currently under consideration for publication elsewhere.

Abstract:

Abstract Diabetes mellitus is an enduring disease related with significant morbidity and mortality. The main pathogenesis behind this disease is its numerous micro- and macrovascular complications. In developing countries, diabetic retinopathy (DR) is one of the major sources of vision impairment in working age population. DR has been classified into two categories: proliferative diabetic retinopathy (PDR) and non-proliferative diabetic retinopathy (NPDR). NPDR is further classified into mild, moderate and severe, while PDR is further classified into early PDR, high risk PDR and advanced diabetic eye disease. DR is a disease caused due to high blood glucose levels which result in vision loss or permanent blindness. High-level advancements in the field of bio-medical image processing have speeded up the automated process of disease diagnoses and analysis. Much research has been conducted and computerized systems have been designed to detect and analyze retinal diseases through image processing. Similarly, a number of algorithms have been designed to detect and grade DR by analyzing different symptoms including microaneurysms, soft exudates, hard exudates, cotton wool spots, fibrotic bands, neovascularization on disc (NVD), neovascularization elsewhere (NVE), hemorrhages and tractional bands. The visual examination of the retina is a vital test to diagnose DR-related complications. However, all the DR computer-aided diagnostic systems require a standard dataset for the estimation of their efficiency, performance and accuracy. This research presents a benchmark for the evaluation of computer-based DR diagnostic systems. The existing DR benchmarks are small in size and do not cover all the DR stages and categories. The dataset contains 1445 high-quality fundus photographs of retinal images, acquired over 2 years from the records of the patients who presented to the Department of Ophthalmology, Holy Family Hospital, Rawalpindi. This benchmark provides an evaluation platform for medical image analysis researchers. Furthermore, it provides evaluation data for all the stages of DR.

Abstract:

During the COVID-19 pandemic, the effectiveness of teacher performance can be seen from the quality of teacher performance in implementing online learning involving information and communication technology media. This study aims to analyze more deeply the effectiveness of teacher performance during the covid-19 pandemic in the implementation of online learning. The type of research used is qualitative research. The research subjects were principals, 2 teachers, 2 students, and 2 guardians. The research instruments are observation sheets and interview guidelines. Data collection techniques are interviews and observation. The data analysis technique used the Miles and Huberman model. The results showed that the effectiveness of teacher performance during the COVID-19 pandemic was classified as less effective. The quality of the work of teachers is classified as less effective because of the many obstacles in the implementation of learning during the COVID-19 pandemic. The teacher's punctuality decreases. Teacher initiatives during the pandemic are relatively ineffective. Teachers' ability during the COVID-19 pandemic is classified as less effective due to limited infrastructure, internet quotas, and unstable networks that do not support online learning processes involving technology. Communication during the covid-19 pandemic is classified as less effective because of the many obstacles that cause learning not to take place so that there is no effective communication.

Abstract:

Manufacturing industry has been developed outrageously during the past decade. The scenario also applies on Malaysian industry where 22.3% of the economy is generated from the manufacturing industry. Numerous latest concepts and technologies have been implemented by manufacturing firms to increase their productivity, product variety and efficiency. However, these changes also provide certain challenges by increasing manufacturing complexity and decreasing sustainability. Generally, manufacturing complexity is classified into internal and external complexity. This research intends to arrange the elements of internal manufacturing complexity (IMC) according to the priority through the period of enhancing sustainability. IMC elements were clustered into organizational, operational and productivity complexity. Fuzzy analytic hierarchical process was implemented in this research as multi criteria decision making method in IMC management. The results found that IMC priority sequence started with productivity, followed by organizational and operational complexity. Productivity complexity with dominant weightage of 0.5302 was emphasized by three elements which are quality inspection process, cost reduction and time reduction respective to the sequence. Meanwhile, organizational complexity slightly led operational complexity by a difference of 0.059. The results show that the Malaysian manufacturing industry is very keen on the product quality and conforms to the requirements. This research could aid firms and researchers to focus on more important elements in decision making for bigger impact on overall performance.

Abstract:

The fusion of mechatronics, communication, control, and information technologies has introduced new automation paradigms into the production environment. Plug-and-play flexible manufacturing systems will become suitable approaches in the future for the development of modular, flexible, and reconfigurable manufacturing systems, addressing the requirements of global markets. This article introduces a Petri Net model-driven methodology for the development, validation, and operation of a radio-frequency identification-enabled decentralized flexible manufacturing system. After analyzing the manufacturing processes and resources of a flexible manufacturing system, the manufacturing resources are classified into active and passive resources. Each active resource is equipped with a radio-frequency identification reader and each passive resource is banded with a radio-frequency identification tag. Real-time state and behavior logic models are built for manufacturing resources based on extended Petri Nets; the models are translated into XML and integrated with the manufacturing resources. In this fashion, each manufacturing resource becomes an autonomous agent, and it can make self-decisions and update its status through the twinned models. In this manner, automatic perception and process control are realized. Finally, the effectiveness and feasibility of the method are verified in an experimental system.

Abstract:

Energy storage is a key technology for many purposes and in particular for air conditioning plants and a successful exploitation of solar energy. Thermal storage devices are usually classified as either variable temperature (“sensible heat”) or constant temperature (“latent heat”) devices. For both models a basic question is to determine the efficiency suitably: Only exergy efficiency appears a proper way. The aim of this paper is to examine exergy efficiency in both variable and constant temperature systems. From a general statement of exergy efficiency by the present author, two types of actual definitions are proposed, depending on the fact that the exergy of the fluid leaving the thermal storage during the charge phase can be either totally lost or utilized elsewhere. In addition, specific remarks are made about the exergy of a system in a periodically varying temperature environment.

Abstract:

Purpose – The purpose of this paper is to review the current status of additive manufacturing (AM) used for tissue engineering (TE) scaffold. AM processes are identified as an effective method for fabricating geometrically complex objects directly from computer models or three-dimensional digital representations. The use of AM technologies in the field of TE has grown rapidly in the past 10 years. Design/methodology/approach – The processes, materials, precision, applications of different AM technologies and their modified versions used for TE scaffold are presented. Additionally, future directions of AM used for TE scaffold are also discussed. Findings – There are two principal routes for the fabrication of scaffolds by AM: direct and indirect routes. According to the working principle, the AM technologies used for TE scaffold can be generally classified into: laser-based; nozzle-based; and hybrid. Although a number of materials and fabrication techniques have been developed, each AM technique is a process based on the unique property of the raw materials applied. The fabrication of TE scaffolds faces a variety of challenges, such as expanding the range of materials, improving precision and adapting to complex scaffold structures. Originality/value – This review presents the latest research regarding AM used for TE scaffold. The information available in this paper helps researchers, scholars and graduate students to get a quick overview on the recent research of AM used for TE scaffold and identify new research directions for AM in TE.

Abstract:

"This paper highlights the Economic Community of West African States [ECOWAS] mode of response to the Malian conflict between 2012 and 2021 and identifies various gaps therein. It seeks to explain why ECOWAS has found it difficult to resolve the Malian conflict in spite of its commitment and experience in conflict resolution in the subregion. Secondary data are used for the study and presented qualitatively. The study reveals that the towering interest of Algeria and other neighbors in the chaotic northern Mali, as well as French interest in its former colony hindered ECOWAS initiative and its effectiveness in resolving the conflict. The paper recommends ECOWAS’ involvement in negotiations at the next peace agreement, and the drawing up of a roadmap for implementing such agreement. Besides, ECOWAS needs to address governance deficits in Mali and elsewhere in the subregion through peer review mechanism and increase its capacity to respond to violent conflicts beyond microstates and Anglophone enclaves in the region.

Abstract:

Additive manufacturing (AM) offers the possibility to produce components in a resource-efficient and environmentally friendly way. AM can also be used to optimise the design of components in mechanical and physical terms. In this way, functionally integrated, lightweight, highly efficient, and innovative components can be manufactured with the help of additive manufacturing in terms of Industry 4.0. Furthermore, requirements in the automotive industry for drivetrain components are increasingly being trimmed in the direction of efficiency and environmental protection. Especially in electromobility, the topic of green efficiency is an essential component. Exhaust emission legislation and driving profiles for evaluating vehicles are becoming increasingly detailed. This offers the potential to apply the advantages of AM to vehicle types such as conventional, utility vehicles, and nonroad mobile machinery (NRMM), independent of the electrical drivetrain technology (hybrid or fully electrical). AM also allows for us to produce optimally adapted components to the respective requirements and use cases. In this review, the intersections of AM and electromobility are illuminated, showing which solutions and visions are already available for the different vehicle types on the market and which solutions are being scientifically researched. Furthermore, the potential and existing deficit of AM in the field of electromobility are shown. Lastly, new and innovative solutions are presented and classified according to their advantages and disadvantages.

Abstract:

Manufacturing companies have to adapt existing factories due to changing customer demands and new technologies. The coordination of several engineering changes in manufacturing systems is a key factor for the efficiency of their implementation. In this paper, a concept for planning and controlling of multiple engineering changes is presented. The concept includes the preselection, planning and execution of engineering changes. The engineering changes can be classified with regard to their relevance and urgency. The needed work steps for the implementation are deduced from the software-based planning and the time schedule for the work steps is created.

Abstract:

Generally speaking, the flexible manufacturing systems can be classified into two main groups: open-loop and closed-loop systems. In this investigation, a recursive formulation is developed for the dynamic analysis of open-loop flexible manufacturing systems. The nonlinear generalized Newton-Euler equations are developed for rigid and deformable bodies that undergo large translational and rotational displacements. These equations are formulated in terms of a set of time invariant scalars, vectors and matrices that depend on the spatial coordinates as well as the assumed displacement fields, and these time invariant quantities represent the dynamic coupling between the rigid body motion and elastic deformation. The method to solve equations of motion for open-loop systems consisting of interconnected rigid and deformable bodies is presented in this paper. This method applies recursive method with the Newton-Euler method for deformable bodies to obtain a large, loosely coupled system equations of motion. The solution techniques used to solve for the system equations of motion can be more efficiently implemented in the modern computer systems. The algorithms presented in this paper are demonstrated by using cylindrical joints that can be easily extended to revolute, slider and rigid joints. The recursive formulation developed in this investigation is illustrated by a practical numerical example.

Abstract:

The function integration, process integration and information integration of the manufacturing system are all in need of the support of the personnel integration. But the complicated relationship among personnel has caused difficulties in personnel integration. In order to analyze the correlation between personnel in manufacturing system, an analysis method based on the relation degree matrix was proposed, meanwhile the personnel in manufacturing system was classified according to the product life cycle(PLC). The above work has paved the path for the further development of a kind of operation mode for personnel integration in manufacturing system based on PLC (MOPI). The mode is composed of four layers, which are the target layer, the PLC layer, the personnel layer, and the supporting system layer. The above mode was implemented in a local manufacturing enterprise, and positive application effect was achieved.

Abstract:

Purpose FOV splicing optical remote sensing instruments have a strict requirement for the focal length consistency of the lens. In conventional optical-mechanical structure design, each optical element is equally distributed with high accuracy and everyone must have a high machining and assembly accuracy. For optical remote sensors with a large number of optical elements, this design brings great difficulties to lens manufacture and alignment. Design/methodology/approach Taking the relay lens in an optical remote sensing instrument with the field of view splicing as an example, errors of the system are redistributed to optical elements. Two optical elements, which have the greatest influence on modulation transfer function (MTF) of the system are mounted with high accuracy centering and the other elements are fixed by gland ring with common machining accuracy. The reduction ratio consistency difference among lenses is compensated by adjusting the optical spacing between the two elements. Findings Based on optical system simulation analysis, the optimized structure can compensate for the difference of reduction ratio among lens by grinding the washer thickness in the range of ±0.37 mm. The test data for the image quality of the lens show that the MTF value declined 0.043 within ±0.4 mm of space change between two barrels. The results indicate that the reduction ratio can be corrected by adjusting the washer thickness and the image quality will not obviously decline. Originality/value This paper confirms that this work is original and has not been published elsewhere nor is it currently under consideration for publication elsewhere. In this paper, the optimum structural design of the reduction relay lens for the field of view stitching applications is reported. The method of adjusting washer thickness is applied to compensate for the reduction ratio consistency difference of lenses. The optimized structure also greatly reduces the difficulty of lenses manufacture, alignment and improves the efficiency of assembly.

Abstract:

Purpose This paper aims to investigate the printability of photocurable PDMS with digital light processing (DLP) in terms of dimensional accuracy, mechanical properties, isotropy and postcure shrinkage. Design/methodology/approach The photocurable PDMS was made from methacrylated PDMS-macromer and 2,4,6-Trimethylbenzoyldi-Phenylphosphinate (TPO-L) photoinitiator. The PDMS was printed using different orientations, sizes and post-exposure conditions and then evaluated by tensile test and microscope to determine the printability. Findings Printed parts show good accuracy and low shrinkage, but high directionality in modulus, ductility and strength. The dimensional error is less than 2% and the shrinkage rates are less than 0.52%. In contrast, the modulus varies between 0.87 and 0.96 MPa depending on print orientation, elongation varies from 34.7% to 66.4% and strength varies from 0.23 to 0.49 MPa. Originality/value This study quantitatively characterizes the printability of photo curable PDMS with DLP, which has not been reported elsewhere. This paper also discusses the challenges of PDMS printing for future advancement.

Abstract:

This series of two papers focuses on the determination and clarification of the characteristics of the forced response of bladed disks that exhibit a mistuning pattern that is either harmonic or partial. Harmonic mistuning refers to single wavelength variations in structural properties along the disk while partial mistuning is associated with blade characteristics that are random in a specific sector and tuned elsewhere. The results of this analysis demonstrate that many features of the response of these simple systems match not only qualitatively but also quantitatively their counterparts on randomly mistuned bladed disks. Relying on these similarities, simple and reliable approximations of the localization factor and of the mean response are easily derived that exemplify the usefulness of harmonic and partial mistuning patterns. Finally, it is demonstrated both theoretically and by comparison with simulation results that the maximum amplitude of response of a disk closely follows a Weibull-type distribution in all coupling situations, from very weak to very strong.

Abstract:

Large manufacturing industries have been able to successfully reduce cost and cycle time through the use of Manufacturing Resource Planning (MRP II) systems and principles to control material flow and the production process. Ship construction cannot be neatly classified as a manufacturing process. The complex relationships involved with the installation and activation of ship's systems more closely resembles a construction operation. Work of this type has traditionally been controlled through an activity based network scheduling system. However, MRP II principles offer numerous benefits for the shipbuilding industry. This paper discusses an approach to planning, scheduling, and management of ship construction which takes advantage of benefits from both approaches. By using both network scheduling and MRP II in an integrated scheduling system, a shipyard will be better able to plan and execute the ship construction process.

Abstract:

This paper outlines a diagnostic entity called ‘Pathological Habit Disorder’ which is suggested for inclusion in the DSM as an Axis II option. Specific areas of concern, either mental (Axis I) or physical (Axis III), would delineate the syndrome. Pathological Habit Disorder (PHD) points to treatment options where the syndrome is wholly or partly habit-driven. Whether the syndrome is habit-driven or not will remain a clinical judgement even though many conditions, previously thought immutable except by medication, are proving accessible to behavioural engineering. In the ICD system, PHD seems to fit in “Special Symptoms or Syndromes not elsewhere Classified”. It is demonstrably useful to have a diagnosis such as PHD and to incorporate it into the body of medical classification, recognizing current practices for dealing with unwelcome or damaging habits.

This study shows the morphological changes of Saccharomyces cerevisiae EC1118 during the second fermentation of Spanish cava wines, in relation with progression of fermentation and aging. In the first stages of active fermentation, and associated with the increase in viable counts, budding cells and a relative homogeneity in cell size were observed. Close to the moment of sugar exhaustion cells acquired the morphology of stationary phase, to finally enter in a death phase with cell size reduction, and cytoplasm alterations including inhomogeneity, refringency, and detachment of the cell wall. At the beginning of this step structures reminiscent to autophagosomes are observed. This is in accordance with the appearance of molecular markers of autophagy described elsewhere in similar winemaking conditions.

Abstract:

The digitalization of the economy provokes the rethinking of manufacturing processes. Despite numerous publications related to Industry 4.0 as a manufacturing approach, the production of fully digital and crypto-asset products was poorly researched. Besides having a supplementary role, crypto-assets may form an entire smart city product. The authors assess the manufacturing of smart city products, fully or partially formed by crypto-assets. The initial issuance of the crypto assets was usually addressed as an Initial Coin Offer, or through the process of increasing the issuer’s capital. The authors assess the Initial Coin Offer, and address it, like manufacturing to produce products for sale. The authors classify all milestones related to the crypto-assets’ issuance, distribution, and revaluation, and assign incomes and expenses to each milestone. Additionally, the ICO-based production costs and revenues were classified according to crypto-asset types, as defined by European Economic Area legislative acts.

Abstract:

For decades, industrial companies have been collecting and storing high amounts of data with the aim of better controlling and managing their processes. However, this vast amount of information and hidden knowledge implicit in all of this data could be utilized more efficiently. With the help of data mining techniques unknown relationships can be systematically discovered. The production of semiconductors is a highly complex process, which entails several subprocesses that employ a diverse array of equipment. The size of the semiconductors signifies a high number of units can be produced, which require huge amounts of data in order to be able to control and improve the semiconductor manufacturing process. Therefore, in this paper a structured review is made through a sample of 137 papers of the published articles in the scientific community regarding data mining applications in semiconductor manufacturing. A detailed bibliometric analysis is also made. All data mining applications are classified in function of the application area. The results are then analyzed and conclusions are drawn.

Purpose – Within team-oriented approaches, tasks are assigned to teams before being assigned to workstations as a reality of industry. So it becomes clear, which workers assemble which tasks. Design/methodology/approach – Team numbers of the assembly line can increase with the number of tasks, but at the same time, due to physical situations of the stations, there will be limitations of maximum working team numbers in a station. For this purpose, heuristic assembly line balancing (ALB) procedure is used and mathematical model is developed for the problem. Findings – Well-known assembly line test problems widely used in the literature are solved to indicate the effectiveness and applicability of the proposed approach in practice. Originality/value – This paper draws attention to ALB problem in which workers have been assigned to teams in advance due to the need for specialized skills or equipment on the line for the first time.
