A fixture is a special tool used to accurately and stably locate the workpiece during machining process. Proper fixture design improves the quality and production of parts and also facilitates the interchangeability of parts, which is prevalent in much of modern manufacturing. The purpose of this paper is to combine the rule‐based reasoning (RBR) and case‐based reasoning (CBR) method for machining fixture design in a virtual reality (VR) based integrated system.

In this paper, an approach combining the RBR and fuzzy comprehensive judgment method is proposed for reasoning suitable locating features and clamping features. Based on the reasoning results, a CBR method for machining fixture design is then presented.

The paper finds that the proposed system is an efficient tool for machining fixture design.

The proposed system enables the designers to perform fixture design with automated fixture locating method reasoning and make a new fixturing solution quickly by referencing previous design cases.

A VR application for machining fixture design is presented.

Argues that the design of the Volvo Uddevalla plant may be described as a process with an “internal logic” in which design options were eliminated through irreversible design decisions until only one alternative remained ‐ an unorthodox alternative comprising, for example, long cycle time work never used before for full‐scale production of automobiles. Contends that the most innovative features of the Uddevalla plant ‐ i.e. the detailed layout in the assembly workshops and the corresponding unorthodox production principles used ‐ were in many respects an unanticipated outcome of the design process. Pre‐existing gross layout of the plant as well as the interaction between the materials feeding techniques adopted and the operation of the automated guided vehicle system. When this was perceived by the Volvo managers, the design process had passed the point of no return, i.e. the investments made and lack of time prevented regression to more traditional layouts and production principles.

The purpose of this paper is to present and develop an ontology-based approach for automatic generation of assembly sequences.

In this approach, an assembly sequence planning ontology is constructed to represent the structure and interrelationship of product geometry information and assembly process information. In the constructed ontology, certain reasoning rules are defined to describe the knowledge and experience. Based on the ontology with reasoning rules, the algorithm for automatically generating assembly sequences is designed and implemented.

The effectiveness of this approach is verified via applying it to generate the assembly sequences of a gear reducer.

The main contribution of the paper is presenting and developing an ontology-based approach for automatically generating assembly sequences. This approach can provide a feasible solution for the issue that mathematics-based assembly sequence generation approaches have great difficulty in explicitly representing assembly experience and knowledge.

The purpose of this study is to examine the attitudes of students in higher educational institutions in Jordan towards the use of online design studios during coronavirus disease 2019 (COVID-19) lockdown and discusses how their use could enhance the learning process.

615 undergraduate students studying architecture in Jordanian universities were recruited to explore the factors that constituted and affected their perceptions of online design studios.

The findings of this study highlight that many of the participants felt uncertain about aspects of their online learning experience and wanted more guidance and support. Reasons of this disengagement include technical factors, such as poor network quality and lack of familiarity with the new applications. Students and tutors' personal situations when working and studying from home are also relevant due to the tutors' lack of expertise in online teaching, and the limitations of peer interaction. Together, these factors can make the experience of the online design studio more challenging.

The sample was nationally representative of architecture students from various institutions. However, the study was limited to an exploration of students' opinions, and it did not include the points of view of tutors and decision-makers.

This research was conceived during the period of the COVID-19 lockdown, whilst both tutors and students were experiencing dramatic changes in their modes of teaching and learning due to the sudden move from on-campus design studios to a virtual alternative, with only the bare minimum of resources and relevant experience. Learners' perspectives can enhance understanding of online design studios to assess their quality and effectiveness.

Examines leadership and school restructuring. Drawing upon postmodern/poststructural theory, argues that a new conception of educational leadership is required as reformers contemplate educational reconfiguration. Argues that the metaphorical notion of leadership as design is appropriate and valuable as reformers seek to consider plans to restructure schools. Traces the likely practical bearings of leadership as design upon the roles, rules, relationships, and results attached to present‐day school restructuring efforts.

The sustainable development goals (SDGs) were introduced by the United Nations in 2016 to replace the millennium development goals (MDGs). This chapter examines the impact of integrating these goals within a design challenge, as part of a level 3 undergraduate degree module. Design Values, Issues and Ethics is an expansive module, aiming to broaden the students’ discipline focus and allow them to expand their learning within a new landscape. This module promotes the utilization of nature-based intelligences to establish solutions to a community’s basic need to survive and thrive. The SDGs were integrated through embedding them as part of a future-building scenario, supported by a series of exercises and seminars. Students were then asked to reflect on how the SDGs had impacted their design process, and to consider ethical and value dimensions. These reflections were used to analyze the effectiveness of the SDGs as key principles for an ethical design intention. Integrating the SDGs within the design curriculum has served to promote a connectivity of systems that were largely separated prior to this pilot.

This study explored the virtual design studio as a transformative learning model for the disaster and resilience context, including the factors that affect students' perceptions and experiences of the quality of this adaptation.

Data obtained from 248 students who took online design studios during the lockdown in 15 universities in Jordan highlight many factors that make the experience of the online design studio more challenging. Despite these challenges, strongly positive aspects of the online studio were evident and widely discussed.

A model of a hyper-flexible design studio in which students can have a direct contact with their instructor when needed – in addition to online activities, reviews and written feedback – is highly recommended for the beginner years. This HyFlex model will enrich students' learning and understanding of the fundamentals of design and ensure that technology solutions deliver significant and sustainable benefits.

For students, studying architecture necessitates a fundamental shift in the learning mode and attitude in the transition from school. Beginner students are often surprised by the new mode of learning-by-doing and the new learner identity that they must adopt and adapt to in the design studio. Moreover, due to the coronavirus disease 2019 (COVID-19) pandemic, architecture teaching has moved online. Both instructors and students are experiencing dramatic changes in their modes of teaching and learning due to the sudden move from on-campus design studios to a virtual alternative, with only the bare minimum of resources and relevant experience.

Cost and time are two of the primary benchmarks in which construction projects are measured. A variety of factors, however, affect cost and time on construction projects, as identified in previous research. This has led to a need for better understanding how factors affecting cost and time overruns on public construction projects can be managed more efficiently. The purpose of this paper is to address these issues.

In this study 26 factors affecting cost and time overruns on construction projects were identified, through qualitative interviews with project managers from Danish governmental agencies and through a literature review. Through principal component analyses the 26 factors were subsequently narrowed down to four primary latent factors.

The identified four latent factors affecting cost and time overruns on public construction projects were lack of quality management, lack of project pre-planning, lack of user management and lack of project management.

Previous research has focussed on increasing knowledge by identifying and ranking factors affecting time and cost performance. This has led to the identification of an overwhelming number of factors to use for managing construction projects. The present research reduced the number of factors by clustering them into key latent factors responsible for most of the deviation in performance, narrowing the scope of construction cost and time management into a few tangible key focus areas. This supports and improves fast decision-making that is necessary in a changeable environment such as construction.

The paper aims to examine the concept of architectural design communication (ADC) for updating design studio dynamics in architectural education during the Covid-19 pandemic. Within this perspective, the changing and transforming contents of architectural education, the thinking, representation and production mediums are examined through the determined components of ADC. There are five components in the study, which are (1) Effective Language Use, (2) Effective use of Handcrafts, (3) Effective Technical Drawing Knowledge, (4) Effective Architectural Software Knowledge and (5) Outputs.

The research method is based on qualitative and quantitative methods; a survey study is applied and the comparative results are evaluated with the path analysis method. The students in the Department of Architecture of two universities have been selected as the target audience. Case study 1 survey is applied to Altinbas University (AU) and Case study 2 survey is applied to Universitat Politecnica de Valencia (UPV) students during the COVID-19 pandemic; ‘19-‘20 spring term, online education.

As a result, two-path analysis diagrams are produced for two universities, and a comparative analysis is presented to reveal the relationships of the selected ADC components.

This paper fulfills an identified need to study how ADC can be developed in online education platforms.

This paper aims to provide a new methodological approach by applying Neo-Kohlbergian considerations in historical context to an analysis of the late speaker of Deutsche Bank Dr Alfred Herrhausen’s moral reasoning process.

A wide range of methods is used, including analyzing Herrhausen interviews, biographies, speeches, statements and further written material, as well as interviews of his contemporaries conducted by this researcher to derive the most accurate posthumous depiction of Herrhausen’s moral reasoning.

The study reveals that Herrhausen was indeed a person of significant moral character when judged by his activist stance on several highly salient global issues.

The thought construct Kohlbergian scholars have been providing is deeply imbedded in a tradition of continental philosophy. While the underlying philosophy in Kohlberg’s cognitive moral development model provides much more than is often considered when used in the field of business ethics, discourse ethicists still consider Kohlberg’s ideas a cornerstone of their philosophical ventures.

Herrhausen has become an iconic figure in Germany, often used by politicians as an aspirational standard and corrective to the current management elites’ mishaps. Internationally, he played an important role as a global manager on the political stage by arguing for a Chapter 11 solution for highly indebted countries during the late 1980s.
