Abstract

Purpose

This paper aims to present a novel lightweight distribution grid operating robot system with focus on lightweight and multi-functionality, aiming for autonomous and live-line maintenance operations.

Design/methodology/approach

A ground-up redesign of the dual-arm robotic system with 12-DoF is applied for substantial weight reduction; a dual-mode operating control framework is proposed, with vision-guided autonomous operation embedded with real-time manual teleoperation controlling both manipulators simultaneously; a quick-swap tooling system is developed to conduct multi-functional operation tasks. A prototype robotic system is constructed and validated in a series of operational experiments in an emulated environment both indoors and outdoors.

Findings

The overall weight of the system is successfully brought down to under 150 kg, making it suitable for the majority of vehicle-mounted aerial work platforms, and it can be flexibly and quickly deployed in population dense areas with narrow streets. The system equips with two dexterous robotic manipulators and up to six interchangeable tools, and a vision system for AI-based autonomous operations. A quick-change tooling system ensures the robot to change tools on-the-go without human intervention.

Originality/value

The resulting dual-arm robotic live-line operation system robotic system could be compact and lightweight enough to be deployed on a wide range of available aerial working platforms with high mobility and efficiency. The robot could both conduct routine operation tasks fully autonomously without human direct operation and be manually operated when required. The quick-swap tooling system enables lightweight and durable interchangeability of multiple end-effector tools, enabling future expansion of operating capabilities across different tasks and operating scenarios.

Abstract

HyFlex course design is an effective instructional course design that combines active and transformative learning techniques. HyFlex course design encourages active learning by focusing on interactive activities, discussions, and collaboration. It also allows learners to collaborate effectively and flexibly as a community, providing peer support and opportunities for authentic dialogue and learning experiences. HyFlex course design provides the opportunity for transformative learning through its ability to offer personalized educational experiences to individuals. It facilitates greater customization of the learning experience, allowing individual learners to access tailored educational modules, offer personalized educational experiences to individuals, and effectively develop and build independent and critical thinking skills. This conceptual review, supported by implications from HyFlex literature and triangulated with experts' views undertaking a Delphi study, facilitates understanding the current state of research in HyFlex course design and future application strategies. Existing research has identified HyFlex courses as a promising means of engaging students in active learning. Allowing students to learn through flexibly predesigned mixed online and in-person experiences enables higher levels of student autonomy and supports students in taking more ownership of their learning. This approach can facilitate an understanding of how HyFlex courses can improve active learning practices in higher education. The review study findings identify the reported alignment issues and challenges, suggest four strategies and actions for policymakers and stakeholders, and provide a suggested research agenda for bridging identified research gaps.

Future research can provide evidence of the benefits of HyFlex course design and how flexible course design can address the challenges of traditional face-to-face courses, such as reduced student engagement, lack of student-centered approaches, and limited support for different learning styles. Further research can focus on strategies that can be used to promote active learning in HyFlex courses. Moreover, research can investigate how this kind of course design can equip educators with the skills and knowledge needed to design and implement effective and meaningful active learning experiences. Finally, research can assess the potential impact of HyFlex course design on student outcomes, including performance, satisfaction, and engagement.

Abstract

Purpose

This study aims to examine the key components to facilitate flexible work arrangement (FWA) and the issues and challenges arisen in preparing the workplace for FWA during Covid-19, and to recommend better approach of FWA implementation in workplace.

Design/methodology/approach

This study adopted extensive literature review and case studies approach using interviews and observations to determine the key components to facilitate FWA and the issues and challenges arisen in preparing the workplace for FWA during Covid-19, and to recommend better approach of FWA implementation in workplace. Three offices that owning FWA experience during Covid-19 and featuring flexible workspace concepts, elements and layouts in Klang Valley, Malaysia were chosen as case studies.

Findings

Findings have suggested that there are four components required to form flexible workspace for FWA adoption, such as open plan workspace design, task-oriented space, hot desking policy and IT infrastructure. Interestingly, the interview findings do not support the idea that the flexible furniture can facilitate FWA; instead, they believe that versatile, acoustical and aesthetical furniture may be installed when necessary. Among the issues and challenges faced were rearranging and designing open office plan layout, hot desk relocation and reconfiguration of spaces where people may congregate. Lastly, this research recommends that innovative planning software and tools, smart technology and apps, modern IT technology and infrastructure, and digital apps can be introduced to the workplace to help FM manage and monitor the facilities operations, workplace situations and occupancy rates.

Originality/value

Since the outbreak of Covid-19, FWA such as “Work From Home” and remote working have become the mainstream in the workplace, affecting how the workplace looks and feels as flexible working is fundamentally related to the flexible workspace. From Facilities Management (FM) perspective, FWA is the biggest consequence of Covid-19, but it also presents opportunities and certain challenges to incorporate a new office environment and employees’ needs in terms of FWA into the corporate culture.

Abstract

Purpose

The aim of this research is to enlighten the methodology model of Industrial Design Structure (IDeS) that integrates the internal and external customer feedback embodied both in methods of quality function deployment (QFD) and as basis of design for six sigma (DFSS) steps to systematically bring the information across the entire organization, saving overall product development time and resources.

Design/methodology/approach

The paper describes the state of the art enlightened to establish the disadvantages and challenges of other methods taken into consideration in the study like QFD and DFSS that, together with the need of companies to react fast to changes they need to straightforwardly implement product development information across all departments, leading to a mass customization infrastructure. Several application trials of this methodology have been cited.

Research limitations/implications

The research approach chosen for this document presents the concept of a methodology ought to operate most internal branches in a company driven by product design requirements and guidelines. Therefore, researchers are encouraged to develop further studies on the IDeS method are required in order to adapt this methodology to specific management tools that would help to ease information gathering for immediate analysis and modification.

Practical implications

The paper implicates that a need to interchange information systematically across all subdivisions in the organization, as brisk response to VOC reactions is needed to thrive in the market nowadays, leading to a fast product customization scene. However, the industry is heading into adopting an individual customer-centered product conceptualization ought to be driven by design as a key for individualizing an object. Afterward by taking this concept broadly and adopting it would lead to implement a company organization that would be directly affected by the customer's input.

Social implications

The methodology described aims to enable organizations to portray fast and accurate product prototyping, by exploiting technologies from Industry 4.0.

Originality/value

This concept proposes a method to canalize the implementation of DFSS by using the DMADV approach, whilst assessing the challenges of adaptation and keeping up with cultural pace that impacts the behavior of buying and consumption and moreover implementing a seamless communication within all departments in the organization to share the development progress and change requests by using similar information technology tools. This would imply important savings in resources, whilst delivering quality products to the society.

Abstract

Purpose

New ways of working have rapidly increased in organizations, promising employees a better control over their work time, space, and more autonomy. The present study analyzes the relationship between new ways of working and employee engagement and productivity.

Design/methodology/approach

A survey was conducted to evaluate organizational practices developed based on flexible schemes and the relevance of employee engagement for better productivity based on digital tools. Data were analyzed using structural equation modeling.

Findings

New ways of work requires an integration of workspaces' design, social interaction, and individual wellness. Organizations need to recognize how employees' trust, commitment, and passion are fundamental to face current and future changes. Flexibility in time and space and digital tools for work are critical.

Practical implications

A personalization of organizational practices to support individual well-being and flexible and hybrid schemes of work are needed. Developing policies collaboratively to work together respectfully in a hybrid environment is necessary.

Social implications

Hybrid work format is allowing women to balance career and childcare, reducing the wage gap with men. The green imperative has also played a role reducing the amount of carbon monoxide produced via commuter.

Originality/value

The present study exposes how organizational practices must ensure employee well-being and autonomy to perform their tasks. In this regard, employees need to be recognized as individuals, physically and mentally. Attempting to force a one-size-fit-all solution can have detrimental effects on the workforce, particularly on women, people of lower socioeconomic status, and people in less advanced economies. Personalization requests empowerment and democratization at work.

Abstract

Purpose

As an advanced manufacturing method, additive manufacturing (AM) technology provides new possibilities for efficient production and design of parts. However, with the continuous expansion of the application of AM materials, subtractive processing has become one of the necessary steps to improve the accuracy and performance of parts. In this paper, the processing process of AM materials is discussed in depth, and the surface integrity problem caused by it is discussed.

Design/methodology/approach

Firstly, we listed and analyzed the characterization parameters of metal surface integrity and its influence on the performance of parts and then introduced the application of integrated processing of metal adding and subtracting materials and the influence of different processing forms on the surface integrity of parts. The surface of the trial-cut material is detected and analyzed, and the surface of the integrated processing of adding and subtracting materials is compared with that of the pure processing of reducing materials, so that the corresponding conclusions are obtained.

Findings

In this process, we also found some surface integrity problems, such as knife marks, residual stress and thermal effects. These problems may have a potential negative impact on the performance of the final parts. In processing, we can try to use other integrated processing technologies of adding and subtracting materials, try to combine various integrated processing technologies of adding and subtracting materials, or consider exploring more efficient AM technology to improve processing efficiency. We can also consider adopting production process optimization measures to reduce the processing cost of adding and subtracting materials.

Originality/value

With the gradual improvement of the requirements for the surface quality of parts in the production process and the in-depth implementation of sustainable manufacturing, the demand for integrated processing of metal addition and subtraction materials is likely to continue to grow in the future. By deeply understanding and studying the problems of material reduction and surface integrity of AM materials, we can better meet the challenges in the manufacturing process and improve the quality and performance of parts. This research is very important for promoting the development of manufacturing technology and achieving success in practical application.

Abstract

Purpose

This paper investigates how (1) a work environment designed to sustain creativity (i.e. through flexible arrangements and elements of the social-organizational work environment) and (2) the amount of enacted work interactions among employees, interpreted as facilitators of new idea generation (i.e. outdegree centrality in instrumental networks), differently impact creativity and work–life balance.

Design/methodology/approach

The authors conducted a quantitative study in a knowledge-intensive multinational company and collected data through a survey on a sample of 207 workers.

Findings

Findings highlight that flexible work arrangements are positively related to increased work–life balance but not to creativity, whereas having access to a social-organizational work environment designed to foster creativity is associated to an increased level of idea generation, but to a reduction in work–life balance. In addition, centrality in instrumental social networks is also associated to a reduction of work–life balance. Findings thus point to a potential trade-off between structures aimed at increasing creativity and initiatives aimed at engendering work–life balance.

Originality/value

The research contributes to the current debate on new organizational practices for innovation and creativity, highlighting their unexpected implications for workers. The research also contributes to the literature on work–life balance by unraveling previously unexplored antecedents, i.e. social networks and the social-organizational work environment designed for creativity.
