Process-integrated computerized numerical control: an analysis on process-machine coupling and feed scheduling

Computerized numerical controls (CNCs) have been invented for the automation of industrial processes. They are used, when the process to be automated is required to be exact and fast with repeatable quality. Originally, the use of CNCs was primarily focused on milling and drilling processes. Today, CNCs are utilized in a wide range of industrial processes due to the growing importance of automation. However, the integration of process information or adaptation to the needs of these processes to achieve advanced manufacturing with CNCs is difficult: Industrial CNCs are rather closed real-time machining systems. Today, process integration is possible, when the interaction between the process and the machine is decoupled in view of the bandwidth of machine dynamics and process dynamics. There are interfaces that allow for process-motivated control loops that are realized on top of the machine control loop (e.g. chatter control). Then, machine-integrated real-time control is not the focus. Besides, it is often possible to change desired values inside the control loop (position, velocity, acceleration) on an axes basis. In this case, adaptation to the process can be realized in each computation cycle. However, process dynamics and machine axes dynamics are generally treated separately. The same holds for extra actuators (e.g., in the spindle) for position control. This paper has two goals. First, it wants to create an understanding for different levels of process-machine coupling. Second, the problem of direct coupling of process dynamics and machine dynamics is focused. Machining systems design propositions as well as some examples for the coupling of process and machine dynamics in the CNC are given.

Understanding the shift: contextual determinants of classic and alternative servitisation trajectories

PurposeWhile servitization has been recognised for its potential to augment organizational revenue and fortify competitive advantage, the exploration of alternative servitization trajectories to the classical servitization model has been little explored in literature. Recent literature introduces the “service paradox” and presents different trajectories to the classical model, but it does not explain why a company chooses one trajectory instead of another. Therefore, this study aims to provide a model that, based on the contextual factors present, recommends which servitization trajectory the company should choose.Design/methodology/approachThis study uses a combination of design science research (DSR) and context, intervention, mechanisms and outcomes (CIMO) to propose the model. An initial contextual factors list was created based on the literature, refined by the company’s employees and evaluated in three selected initiatives in the focal company. Furthermore, based on the understanding of the CIMO logic elements, four design propositions were elaborated to summarize the main findings of the study.FindingsThe study has demonstrated that the choice of a servitisation trajectory is intricately tied to a multitude of contextual factors, prompting organisations to deviate from conventional models towards alternative paths. Furthermore, the research sheds light on the underlying mechanisms and contextual drivers that shape servitisation decisions within the context of a consumer goods manufacturer. The analysis underscores the pivotal role of market dynamics and strategic adaptability in shaping servitisation strategies, underscoring the importance of customized approaches that cater to the distinct circumstances of each organisations.Originality/valueThe research contributes to both theory and practice by offering profound insights into the complex nature of servitisation, advocating for continuous adaptation and strategic alignment with market demands. For practitioners and decision-makers, the study provides valuable guidance on enhancing service offerings and navigating the complexities of servitisation within specific sectors, fostering a culture of learning and adaptation to drive sustainable growth.

Operationalizing the Circular Economy—A Longitudinal Study on Sustained Circular Action

Circularity is becoming increasingly important for Distribution System Operators (DSOs) as their infrastructure ages and needs replacement, alongside compliance with stringent environmental regulations like the Corporate Sustainability Reporting Directive (CSRD). However, implementing circular economy (CE) practices is challenging due to the fragmented nature of the current CE landscape and its limited interaction with practical application. A longitudinal case study at the Dutch DSO, Liander, focusing on the circularity of distribution transformers, was conducted to generate prescriptive knowledge on operationalizing circularity. This resulted in the formulation of six design propositions for circular action that suggest to (1) initiate small-scale circularity experiments; (2) involve technical and strategic experts; (3) synergize circularity with more urgent, primary goals; (4) translate circular initiatives bottom-up and top-down; (5) collaborate with other DSOs; and (6) create multidisciplinary teams. The propositions suggest to situationally select interventions and build upon the outcomes of previous interventions in order to incrementally contribute to circular change. Other DSOs could use these propositions to optimize their strategy toward circular action. Additionally, the findings contribute to advancing scientific knowledge to implementable actions in order to initiate and sustain circular change.

Heuristic evaluation and end-user testing of a machine learning-based lower-limb exercise training system for management of knee pain in individuals aged 55 years or over

ObjectiveUsing machine learning techniques, we have developed an interactive exercise training system to assist individuals aged 55 years or over with knee pain to perform lower-limb exercises to improve their knee health. The system has three features: video-based exercise demonstrations, real-time feedback on exercise movements, and tracking of exercise performance and progress. The current study aimed to evaluate the design of the computer prototype of the system, and determine its usability and end users’ intention to use it (i.e., acceptance of it). MethodsHeuristic evaluation and end-user testing of the computer-based prototype system were conducted. Three human factors practitioners identified the design deficiencies, with reference to 64 design principles. In addition, 10 individuals with knee pain were recruited to use the prototype system to complete five tasks in the study laboratory. We recorded and examined the task success rate, number of requests for assistance, difficulties encountered during tasks, and perceptions of usability and acceptance. ResultsFour design deficiencies were identified, regarding recognition and recovery of errors, navigation, auditory perception, and help documentation. Most participants had difficulty in calibrating the camera and performing exercises. However, in general, the prototype system was perceived as usable and acceptable. ConclusionsThe use of heuristic evaluation and end-user testing revealed the capacity to systematically detect design deficiencies in interactive self-help systems, allowing for effective system adjustments. Moreover, our system shows potential for individuals managing knee pain, but conducting iterative usability testing is necessary to identify additional improvements. Furthermore, several design propositions have been submitted.

A design science approach to manage spare parts distribution: combining design logic and Goldratt’s thinking processes

PurposeDesign Science (DS) is a relatively new paradigm for addressing complex real-world problems through the design and evaluation of artifacts. Its constituent methodologies are currently being discussed and established in numerous related research fields, such as information systems and management (Hevner et al., 2004). However, a DS methodology that describes the “how to” is largely lacking, not only in the field of OM but in general. The Theory of Constraints (TOC) and its underlying thinking processes (TP) have produced several novel artifacts for addressing ill-structured real-world operations problems (Dettmer, 1997; Goldratt, 1994), but they have not been analyzed from a DS research standpoint. The purpose of this research is to demonstrate how TOC’s thinking process methodology can be used for conducting exploratory DS research in Operations and Supply Chain Management (OSCM).Design/methodology/approachA case study of spare parts replenishment illustrates the use of TOC’s thinking processes in DS to structure an initially unstructured problem context and to facilitate the design of a novel solution.FindingsTOC’s thinking processes are an effective methodology for problem-solving DS research, enabling the development of novel solutions in initially unstructured and wicked problem situations. Combined with structured CIMO design logic TOC’s thinking process offers a systematic method for exploring wicked problems, designing novel solutions, and demonstrating theoretical contributions.Research limitations/implicationsThe implication for research is that TOC’s thinking process methodology can provide important elements of the lacking “how to” methodology for DS research, not only for the field of OM but in general for the field of management.Practical implicationsThe practical outcome of the research is a novel design for dynamic buffer-based replenishment that extends beyond organizational boundaries.Originality/valueThis work shows how the thinking processes can be used in DS research to develop rigorous design propositions for ill-structured problems.

Visible and invisible forest: The cultivation of shade in Winnipeg, Manitoba, Canada

A consideration of the site-specific spatial experience created by urban trees and their cultural dimensions can enrich climate adaptive tree planting strategies in Winnipeg, a city of 850,000 in the central prairies of Canada. The paper begins with an introduction to traditional urban tree planting types and analyses the range of tree planting techniques that currently define public spaces in Winnipeg. A review of the recently published Urban Forest Strategy for Winnipeg highlights current strengths and challenges to climate change related tree planting in the city. Urban tree planting strategies and practices demonstrate a focus on quantifiable goals such as canopy coverage, number of trees planted or ecosystem services, with little reference to how trees define places. However, cities are constituted by the visible forest-the form and patterns of how trees are planted and the spaces they create. They are also shaped by the invisible forest, the diverse ways in which trees evoke different functions, values, and modes of occupation to different people at different times. Two basic approaches to urban tree planting will enrich climate-related tree planting initiatives by synthesizing the visible and invisible dimensions of the urban forest: Prioritizing the collective planting of trees as opposed to the single specimen and acknowledging the cultural dimensions of trees. Two design propositions from students at University of Manitoba demonstrate how trees can articulate the diverse ways people interact with trees through their spatial configuration and planting techniques. One draws upon tree types that acknowledge local agricultural tree planting strategies and the second responds to historical and contemporary Indigenous relationships to riparian trees. Acknowledging the planting of trees as a complex interplay between spatial, ecological, and cultural specificity allows for the communication of new values for the design and stewardship of urban trees and the provision of shade in a climate adaptive city.

Codesign in Action: Design Principles to Successfully Manage Transformative Social Innovation

To meet grand challenges, organizations must rethink how they establish their objectives and processes in a more sustainable way. Social innovation is seen as a very promising way to respond to this call. Nevertheless, social innovation encounters difficulties in scaling and reaching its transformative power. On the basis of the theoretical framework of transition management, our article focuses on the codesign of transformative social innovation by trying to identify how actors can manage it successfully during the experimentation phase. We have conducted research based on the design science methodology to develop both concrete solutions to solve empirical problems and build strong design propositions. The results and design propositions stem from the analysis of three case studies of French social impact bonds (SIBs), which are contractual tools funding social innovation programs. SIBs are, by nature, codesign processes involving different types of stakeholders (private funders, public commissioners, and nonprofit organizations). This article provides six design principles to support the cooperation and alignment of multiple stakeholders to foster their scaling up, which is crucial for perpetuating social innovation. This research contributes theoretically to both the social innovation scaling literature and the transition management framework and offers practical guidelines to help social practitioners to codesign and manage transformative social innovations.

How can technology assessment tools support sustainable innovation? A systematic literature review and synthesis

Sustainability considerations are increasingly important for manufacturing companies seeking to develop products that meet the needs of society and the environment. The way technologies are assessed in the early design stages plays a crucial role in the integration of sustainability into innovation activities – a necessary step towards the development of products and processes with better environmental and social consequences. However, existing sustainability assessment tools are difficult to deploy in the highly uncertain and data-scarce front-end of innovation. In order to ascertain the efficacy of technology assessment methods, a systematic literature review was conducted to systematize best practices in technology assessment and establish a set of design propositions to improve early-stage sustainability assessment. Subsequently, recommendations for designing and effectively implementing sustainability assessment tools in technology development were elicited. Several avenues for future research are proposed, including the testing and refinement of the design propositions and how to operationalize early-stage sustainability assessment.

Design premise and diary study exploring felt senses as data for self-reflection

While mobile and wearable applications leverage biosensing and self-tracking technologies to promote healthy lifestyles through data-based self-reflection, there have been criticisms that they perpetuate the dualistic view that separates mind and body. We examine theoretical premises and design approaches for self-reflection using personal data, and compare them with self-reflection accounts collected from a diary study, in which participants are encouraged to reflect through Focusing on their felt sensations. Based on the analysis of how participants notice, express, question, and respond to their felt senses, we investigate how self-awareness and self-knowledge can be derived from elusive felt sensations and expand the scope of personal data and design for self-reflection. Our findings reveal the gap between theory and practice to design for self-reflection at the limits of biosensing and self-tracking applications, and lead to alternative design propositions for harnessing human senses as personal data for self-reflection.

Stakeholders’ design preferences for instructional gamification

ABSTRACT There is increasing interest in incorporating game design elements in workplace learning, known as instructional gamification. Despite initial positive indications, there is still a need for a deeper understanding of how organisational stakeholders play a role in implementing instructional gamification. This study employed an explanatory sequential mixed-methods approach to identify and understand stakeholders’ instructional gamification design preferences and how these preferences might impact their endorsement of instructional gamification. A survey of 231 individuals at a software company was conducted to gather data on stakeholders’ preferences for instructional gamification. This was followed by in-depth interviews with eight employees to further enhance the understanding of stakeholders’ instructional gamification design preferences. The quantitative findings revealed four interrelated factors concerning the instructional gamification design preferences of the three stakeholder groups. However, the qualitative findings revealed that the stakeholder groups interpreted the items differently. By integrating the quantitative and qualitative findings, the study provides a comprehensive understanding of the factors that enable or hinder stakeholders’ endorsement of instructional gamification in workplace learning. The study also presents four design propositions that facilitate stakeholder endorsement of gamified learning artifacts. The findings have both theoretical and practical implications for designing and implementing instructional gamification in workplace learning environments.

Research-by-Design in Complex Systems: Reflections on Approaches Used to Reimagine Environmentally Sustainable, High-Welfare Poultry Housing Futures

Despite projected global rises in chicken consumption, growing environmental and welfare challenges threaten the future of commercial poultry production. Though some of these challenges, such as biosecurity, sourcing, pollution, and waste, have been thoroughly researched, the open-ended, complex, and interrelated nature of the sector means that it is difficult for poultry producers to know how to change. Design may offer a new way to analyse and reframe these challenges, to speculate on a range of different solutions for these complex systems of production. This paper reflects on the research-by-design methods applied to reimagine environmentally sustainable, high-welfare poultry housing futures. The paper is based on an eighteen-month long, multidisciplinary research project with a large U.K.-based poultry farming integrator, a poultry house ventilation and equipment supplier, and academic partners with expertise in research-by-design and bird welfare. After contextualising challenges faced by the poultry sector, the paper outlines a three-step, iterative approach within which design methods were applied, beginning with (1) a baseline analysis of farm inputs, outputs, actors, and networks, and then (2) a consolidation of themes and scenarios, leading to the development of (3) a compendium of ideas for the future of poultry farming. The Results section presents three design propositions, each imagining different futures by recreating the farm as a system of “closed-loop” flows, reframing the “chicken as client” and challenging current centralised models of production to connect consumers to food provenance and impact. These propositions function as vehicles to test design methods, such as designing for resource flows challenging actor hierarchies and hacking stakeholder networks. While some interesting ideas are presented, the paper highlights the complexity of the challenge and reflects on the value of design to reframe these challenges to collaboratively foster new perspectives and mindsets.

Stress analysis of circular membrane-type MEMS microphones with piezoelectric read-out

In this study, the impact of residual tensile stress on a membrane-type piezoelectric MEMS (Micro Electromechanical Systems) microphone is investigated both theoretically by FEM (finite element method) simulations and experimentally by stress measurements, by manufacturing devices and by recording the acoustic performance. Based on these findings, a design is proposed composing of segmented electrodes which are arranged close to the silicon frame as well as on the inner part of the membrane. The MEMS microphone features an aluminum nitride layer which allows a piezoelectric read-out, and multiple metal bottom and top electrodes distributed radially and azimuthally. FEM simulations were done over a large range of different layer thicknesses, membrane radii, and tensile stress levels, which indicate the existence of a sweet-spot when targeting a maximum output signal. The data showed, that thicker membranes perform better under tensile stress than thinner membranes. Furthermore, a relation between output signal and residual stress level was established, which showed that the FEM predictions agree well with the measurement results of piezoelectric microphones. • Thicker MEMS membranes preferred over thinner counterparts when tensely pre-stressed • Finite element analyses revealed sweet spot for maximizing piezoelectric output • Design propositions for stressed closed membranes without stress relaxing measures • Microphone measurements and finite element methods results agree well

Design propositions for nudging in healthcare: Adoption of national electronic health record systems.

Electronic health records (EHRs) are considered important for improving efficiency and reducing costs of a healthcare system. However, the adoption of EHR systems differs among countries and so does the way the decision to participate in EHRs is presented. Nudging is a concept that deals with influencing human behaviour within the research stream of behavioural economics. In this paper, we focus on the effects of the choice architecture on the decision for the adoption of national EHRs. Our study aims to link influences on human behaviour through nudging with the adoption of EHRs to investigate how choice architects can facilitate the adoption of national information systems. We employ a qualitative explorative research design, namely the case study method. Using theoretical sampling, we selected four cases (i.e., countries) for our study: Estonia, Austria, the Netherlands, and Germany. We collected and analyzed data from various primary and secondary sources: ethnographic observation, interviews, scientific papers, homepages, press releases, newspaper articles, technical specifications, publications from governmental bodies, and formal studies. The findings from our European case studies show that designing for EHR adoption should encompass choice architecture elements (i.e., defaults), technical elements (i.e., choice granularity and access transparency), and institutional elements (i.e., regulations for data protection, information campaigns, and financial incentives) in combination. Our findings provide insights on the design of the adoption environments of large-scale, national EHR systems. Future research could estimate the magnitude of effects of the determinants.

Genotype-Phenotype Mapping for Applied Evolutionary Multi-Objective and Multi-Physics Topology Optimization

We present a multi-objective topology optimization method based on the Non-Sorting Genetic Algorithm II (NSGA-II). The presented approach is a tool for early-stage engineering applications capable of providing insights into the complex relationship between structural features and the performance of a design without a priori assumptions about objective space. Mass reduction, linear elastic deformation, and stationary thermal conduction are considered simultaneously with three additional constraints. The specifically developed genotype-phenotype mapping ensures the practical benefit of obtained design propositions and significantly reduces computational effort to generate a dense set of Pareto solutions. The mapping procedure smooths probabilistically generated structures, removes unconnected material, and refines the spatial discretization for the subsequently used finite element solver. We present sets of Pareto optimal solutions to large three-dimensional design problems with multiple objectives and multiple near-application constraints that are feasible design propositions for engineering design. Geometrical features present in the obtained Pareto set are discussed.

Surviving major disruptions: Building supply chain resilience and visibility through rapid information flow and real-time insights at the “edge”

Disruptive events with damaging consequences afflict supply chains across industries. The survival of the business and its consequent recovery depend on the supply chain's resilience. This exploratory article discusses how technology-driven real-time decision-making in a connected supply chain achieves intended business outcomes of resilience, agility, and visibility. Based on an Integrative Literature Review and adopting a Design Science Research Methodology (DSRM), we propose a distributed approach for real-time inferencing in edge near the data sources for rapid autonomous decisioning and recovery planning under disruption. We develop a framework for building resilience in the supply chain using real-time distributed information sharing in a collaborative partner ecosystem. Visibility across the supply chain is ensured with a Digital Control Tower by making information available to any connected node for synchronized action. The important contribution of this research is building a real-time decision framework for sustainable resilience-building in resource-constrained organizations unable to invest in big data and enterprise systems. A set of design propositions following the CIMO framework is expected to help scholars and practitioners alike. A research agenda is provided for the researchers to take forward hypothesis formulation and empirical validation on the basis of the propositions. (194 words)

Graphical Prediction of Optimum Pinch Point Value with AEA Software Simulation and Validation Applied in Closed Cycle Gas Power Plant

Studying industries energy saving is very important prospect for many researchers in the last four decades. In this respect, better process heat transfer can be achieved to improve process operating and capital cost. Thereafter, obtaining higher amount of heat recovery, which will help to reach system optimum heat exchanger network design. Application of Pinch analysis (PA) in our current study, was found to be as an effective method towards economic solution and assessment for all system thermal processes. Whereby, minimizing energy losses, and thus, prediction of maximum energy saving. In addition, application of "Aspen Energy Analyzer (AEA)" simulation software assist our effort to optimize Heat Exchanger Network design (HEN), with various application scenario towards best design. This study represents a "Case study" as a Brayton closed cycle gas turbine power plant in Al-khairat district, which is one of a number of sites used to generate electricity for Iraq national grid. However, the plant original design is open cycle. This study, represent an attempt to apply (PA) in system closed cycle model with the same working conditions. The results predicted, on the contrary of open cycle, that using closed cycle (PA) with temperature difference ∆Tmin can be acceptable with several design propositions. The optimum (∆Tmin = 15℃) were evaluated in the closed cycle system pinch analysis, thereby the maximum Qrec. process that minimize the QHmin & QCmin requirement were identified by the software simulation for the best HEN design. These results were found as Qrec. = 318.330 MW, QHmin = 88.607 MW and QCmin =39.564 MW.

Enhancing Biocultural Diversity of Wild Urban Woodland through Research-Based Architectural Design: Case Study—War Island in Belgrade, Serbia

In the vortex of the environmental and ecological crises, it is clear that the cosmopolitan way of living is facing uncertainty with no easing in sight. Looking beyond the horizon at what the aftermath will yield, it is quite clear that the meaning of urbanity has to be transformed; the urban life has to support social and ecological well-being, and the city has to intertwine more closely with nature. Therefore, wild urban woodlands (WUWs), often morphologically exclusive, culturally contradictory, and biologically heterogeneous, are recognized together with the other informal wilderness of the city as catalyzers of a newly constructed identity and the first line of defense when the question of the socio-ecological resilience of the city is raised. The present study focuses on how the biocultural diversity of WUWs can be stimulated by architecture and on which principles and restorative components an architectural design should stand on. Taking War Island on the river Danube, in the very heart of Belgrade, Serbia, as the particular case study, a specific assignment was given to students of the Faculty of Architecture in Belgrade to affirm, recuperate, and stipulate the relationship between the nature and the culture of the site. On the threshold of interdisciplinarity, a net of coordinated values is set up based on a theoretical, analytic, and typo-morphological approach, gathering the eco-cultural aspects, components, and characteristics of the place. On the bases of the students’ research-based design propositions, the results show different design paths promoting accessibility and security, restoring social responsibility and awareness, and regaining the socio-ecological well-being of the place. The conclusions drawn from the study open the perspective of the alliance between nature and culture through an architectural infrastructure that heals the landscape and induces its therapeutic properties, enhancing the biocultural diversity of the place and proclaiming a kind of hedonistic sustainability for the future life of cities.

Toward Excellence in Photocathode Engineering for Photoelectrochemical CO2 Reduction: Design Rationales and Current Progress

AbstractPhotoelectrochemical CO2 reduction reaction (PEC CO2RR) is a promising technology which offers the possibility of a carbon‐neutral solar fuel production via artificial photosynthesis. The challenging proton‐coupled multielectron transfers with high energy barriers in CO2RR however pose as a huge hindrance to the technology, which demands strict specifications in the design of photocathode materials so as to improve PEC performances. This review underscores effective design strategies and current material progress for the judicious assembly of photocathode materials for CO2RR. The review begins with elucidating the fundamental principles of CO2 reduction process and photocathode electrochemistry. Based on these, the design criteria and trade‐offs in the design of PEC CO2RR photocathodes are highlighted. The various promotive strategies for photocathodes and their underlying rationales such as doping, defect engineering, nanostructuring, cocatalyst loading, passivation, heterojunction formation, and innovative multijunction configurations are further outlined and design propositions in the area are provided. Following that, various photocathode semiconductor materials categorized into photovoltaic (PV) grade (silicon, III–V semiconductors, chalcogenides) and non‐PV grade (metal oxides) materials are summarized and extensively discussed, along with their recent advances. Finally, perspectives on the design of photocathodes for CO2RR and new paradigms in the field are put forward.

Investigating passive strategies in a cold climate – teaching EDDA in architectural education

This paper describes the results of an architectural teaching module investigating passive building strategies in cold climatic conditions on the case study of Iceland. Focusing on thermal comfort in buildings, usual case study tasks are located in cooling-dominated climates - as vernacular design for hot climate zones offers more passive strategies than for cold climates. As part of the architectural education programme at Jade University of Applied Sciences, students investigated the impact of passive strategies in a building design concept for a hotel in Iceland by applying numerical simulation within the initial design phase. The aim was to develop a holistic energy efficiency strategy and to optimize their initial design propositions exploiting its full potential for high thermal comfort in the guest rooms. Although each student started with an individual research question for a specific passive strategy, i.e., investigating varying construction materials, buffer zones, window-wall-ratio, Trombe walls, etc., all design concepts finally included multi-storey glazed buffer zones contributing to comfortable room temperatures by high solar gains from April to September resulting in a significantly reduced heating load. Furthermore, the study identified several design metrics for passive solar buffer zones to ensure the positive impact throughout the months with varying solar intensity. The teaching module called EDDA (Environmental Digital Design Analysis) is based on simplified 3D models in McNeels Rhinoceros 3D undergoing thermal simulation with a Grasshopper–Ladybug-Honeybee workflow. This allowed the students to iterate their building designs for maximum thermal comfort before adding HVAC systems. Ultimately, EDDA fostered to design climate-sensitive buildings by identifying a suitable set of passive strategies for the predominant climatic conditions as a first – but essential - step towards climate-neutral buildings. At the same time, prospective architects are empowered leading the building sectors towards a carbon-neutral future.
