Abstract

Purpose

The purpose of this paper is to show with figures the potentialities of knowledge‐based engineering (KBE) methods in new product development (NPD). It estimates the business value generated by a tool which integrates the handoff between engineering groups of a large aerospace company.

Design/methodology/approach

The paper is based on three years of observation and interviews at a leading Italian firm. A process‐based approach is used for assessing business value.

Findings

The KBE application automated the preparation of data transferred to computeraided engineering engineers for analysis by computeraided design engineers and reduced the time required by more than 90 percent. This allowed time savings which contributed to enhance product quality.

Research limitations/implications

The paper is based on a single case, though its findings are consistent with prior studies. Future research will implement like applications in other contexts at the subject firm and other firms.

Practical implications

The paper helps managers to understand the uses and potential value of KBE applications, enhancing the awareness of NPD practitioners in a field which is still partially untapped.

Originality/value

The paper combines discussion of the technical aspects of implementing a KBE tool with estimates of performance improvement achieved. It can be a useful illustration of a good practice and a proof‐of‐concept for further implementations in complex engineering settings.

Abstract

Purpose

Blended learning is an emerging trend across many educational settings, adopting the purposeful integration of traditional face-to-face and online teaching to establishing an engaging learning experience for the students. Blended learning provides an ideal platform for the implementation of reusable learning objects (RLOs) as a pedagogical tool to support classroom instruction.

Design/methodology/approach

This study had conducted a quasi-experiment followed by semi-structured interviews to determine if a blended learning approach using RLOs can enhance students’ learning in an undergraduate engineering computer-aided design (CAD) module. This study involved learners studying engineering in two different academic years.

Findings

Students from the first year were taught using traditional face-to-face teaching approach. The cohort of students from the subsequent year adopted a blended learning approach: face to face and access to a series of RLOs. The analysis revealed statistical evidence that the use of blended learning had a significant impact on the students' end of term exam grades in the CAD module in comparison to the students who undertook traditional face-to-face teaching approach. The qualitative findings highlighted the positive impact of RLOs on students’ learning behaviour, engagement and knowledge retention.

Originality/value

This study provided empirical evidence of the benefits of using RLOs as a blended learning tool in engineering domain. From a theoretical perspective, the findings highlighted the importance of good instructional design and sound theoretical underpinning of the pedagogical strategy. From a practical point of view, this study informed academics on how to improve learner's academic achievement using RLOs.

Abstract

This study proposes a design automation system that integrates traditional segmental design processes into a solid unified system composed of need assessment, computer aided design, computer aided engineering and rapid prototyping. The system utilizes the computer network in conjunction with the quality function deployment technique coupled with a well designed expert system to precisely transform customers’ needs into producible product specification. The product is then displayed using a three‐dimensional representation and simulated through numerical analysis using a finite element method. The resulting feasible design alternative is finally linked to the rapid prototyper to produce the sample object. The use of the system is believed to greatly reduce R&D cost and significantly shorten the product design cycle, while closely meeting the customer’s needs.

Abstract

Reports on the computeraided design (CAD) upgrade implementation process at PBR Automotive Pty Ltd, Melbourne, Australia. Views the implementation as successful since many of the desired outcomes have been achieved or surpassed. The key success factors were detailed planning, user involvement and vendor support. These combined to create an atmosphere of excitement in the project and success. Reports on the future plans that include the development of an integrated information system at PBR which will involve customers and suppliers in addition to internal personnel. The CAD system upgrade serves as a launching board for the development of such a system.

Abstract

Purpose

The purpose of this study is to propose an isogeometric analysis (IGA) approach for solving the Reynolds equation in textured piston ring cylinder liner (PRCL) contacts.

Design/methodology/approach

The texture region is accurately and conveniently expressed by non-uniform rational B-splines (NURBS) besides hydrodynamic pressure and the oil film density ratio is represented in this mathematical form. A quadratic programming method combined with a Lagrange multiplier method is developed to address the cavitation issue.

Findings

The comparison with the results solved by an analytical method has verified the effectiveness of the proposed approach. In the study of the PRCL contact with two-dimensional circular dimple textures, the solution of the IGA approach shows high smoothness and accuracy, and it well satisfies the complementarity condition in the case of cavitation presence.

Originality/value

This paper proposes an IGA approach for solving the Reynolds equation in textured PRCL contacts. Its novelty is reflected in three aspects. First, NURBS functions are simultaneously used to express the solution domain, texture shape, hydrodynamic pressure and oil density ratio. Second, the streamline upwind/Petrov–Galerkin method is adopted to create a weak form for the Reynolds equation that takes the oil density ratio as a first-order unknown variable. Third, a quadratic programming approach is developed to impose the complementarity conditions between the hydrodynamic pressure and the oil density ratio.

Abstract

Purpose

Although organizations have more data than ever at their disposal, actually deriving meaningful insights and actions from them is easier said than done. In this concern, the main objective of this study is to identify trends and research opportunities regarding data management within new product development (NPD) and collaborative engineering.

Design/methodology/approach

Bibliometric and systemic analyses have been carried out using the methodological procedure ProKnow-C, which provides a structured framework for the literature review. A bibliographic portfolio (BP) was consolidated with 33 papers that represent the state of art in the subject.

Findings

Most recent researches within the BP indicate new trends and paradigm shifts in this area of research, tackling subjects such as the internet of things, cloud computing, big data analytics and digital twin. Research gaps include the lack of data automation and the absence of a common architecture for systems integration. However, from a general perspective of the BP, the management of experimental data is suggested as a research opportunity for future works. Although many studies have tackled data and collaboration based on computer-aided technologies environments, no study examined the management of the measured data collected during the verification and validation stages of a product.

Originality/value

This work provides a fresh and relevant source of authors, journals and studies for researchers and practitioners interested in the domain of data management applied to NPD and collaborative engineering.
