Abstract

Numerical modelling and simulation of metal forming is rapidly gaining prominence in many industries all over the world due to its effective saving of production time, effort and economy. In order to meet this need a special finite element code FORGE2 has been developed at CEMEF. In this work the theoretical basis of the FORGE2 along with its features such as thermo‐viscoplastic coupling, material compressibility and automatic mesh regeneration is reviewed and an attempt is made to simulate a few industrial forming processes taking into account the complex friction phenomena and thermal environment.

Abstract

Focuses on the inverse problems arising from the simulation of forming processes. Considers two sets of problems: parameter identification and shape optimization. Both are solved using an optimization method for the minimization of a suitable objective function. The convergence and convergence rate of the method depend on the accuracy of the derivatives of this function. The sensitivity analysis is based on a discrete approach, e.g. the differentiation of the discrete problem equations. Describes the method for non‐linear, non‐steady‐state‐forming problems involving contact evolution. First, it is applied to the parameter identification and to the torsion test. It shows good convergence properties and proves to be very efficient for the identification of the material behaviour. Then, it is applied to the tool shape optimization in forging for a two‐step process. A few iterations of the inverse method make it possible to suggest a suitable shape for the preforming tools.

Abstract

Purpose

purpose of this study is to present a Lean Readiness Assessment Model (LRAM) for assessing the readiness of Humanitarian Organizations (HO) for adopting Lean Management (LM) (Johanson et al.) practices. Literature reveals that implementation of LM itself is a cost and most organizations have failed to adopt LM techniques due to a non-readiness status and a non-supportive organizational culture. This situation indicates that the assessment of organizations' readiness before implementation of lean techniques is necessary.

Design/methodology/approach

This was an empirical quantitative study. Based on a synthesis of the literature, a conceptual model was developed by identifying seven critical success factors (CSFs). The CSFs were validated by HO professionals via a questionnaire-based survey. The data from the responses were analysed by applying partial least square structured equation modelling (PLS-SEM) using the SmartPLS3 software.

Findings

A proven LRAM was constructed that consists of CSFs (independent and mediating variables), which have reflected positive coefficients and significant t >1.96 and p < 0.05 values. The CSFs that are significant include process management, planning and control management, customer relationship management, human resource management, communication and coordination management and a positive organizational culture. The CSFs of supplier relationship and top management and leadership had insignificant t and p values and were dropped from the final LRAM.

Originality/value

This is a unique and rare study in its nature which developed LRAM for HO sector. The contribution of this model is to improve the efficiency and sustainability (economic and social aspects) of an HO under scarce resource conditions.

Abstract

Purpose

This study aims to identify and prioritize the key practices and strategies for effective global sourcing and supply chain management (SCM).

Design/methodology/approach

The study uses a combination of Pareto analysis and multi-objective optimization based on ratio analysis research methodology to analyze and establish the relationships among the identified key practices and strategies. Pareto analysis enables organization to prioritize organizational efforts and resources by focusing on the most critical factors.

Findings

The study shows that the “eco-friendly sourcing strategy”, “lean manufacturing” and “tool cost analysis” are the top critical practices and strategy variables for global sourcing and SCM, whereas the “risk management”, “procurement strategy” and “leverage digital solutions” are the critical practices and strategy variables.

Research limitations/implications

The findings of this research can also assist organizations in making informed decisions to optimize their global sourcing and supply chain operations.

Originality/value

By using these methods, this research paper gives valuable insights into the critical practices and strategies that can enhance efficiency, mitigate risks and drive success in global sourcing and SCM. The subjects and elements this study identified will serve as a framework and suggestions for further theoretical investigation and real-world implementations.

Abstract

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming, powder metallurgy and composite material processing are briefly discussed. The range of applications of finite elements on these subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE researchers/users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for 1994‐1996, where 1,370 references are listed. This bibliography is an updating of the paper written by Brannberg and Mackerle which has been published in Engineering Computations, Vol. 11 No. 5, 1994, pp. 413‐55.

Abstract

This study investigates the impact of digital disruption on tourism education in the 21st century.

Research problem: Digital disruption is causing a major upheaval in the tourism education sector, which is affecting how teachers instruct and how students learn. The purpose of this study is to investigate ways in which educators can adjust to these changes and to comprehend the impact of digital disruption on tourism education.

Research significance: This study is important because it clarifies the opportunities and problems associated with the digital disruption of tourism education. It offers guidance to educators, decision-makers, and industry participants on how to successfully incorporate digital technologies into curricula for tourism education.

Methods: A mixed-methods strategy integrating quantitative and qualitative methods was employed. An online survey and in-depth interviews with 100 participants – students, professionals in the industry, and educators – were used to gather data. For qualitative data, thematic analysis was employed, whereas descriptive statistics were used for quantitative data.

Frameworks: The study is set up in relation to the theory of digital disruption and how it affects education. The literature on digital technologies in education, transformative learning theory, and the necessity of developing 21st-century skills are also consulted.

Results: Participants generally perceived a moderate to high level of disruption, suggesting that there is a significant level of digital disruption in tourism education. The study emphasizes how critical it is to incorporate new technologies into curricula, stress the value of sustainable development, enhance intercultural competency, and promote cooperation between academic institutions and the travel and tourism sector.

Abstract

Purpose

Traditionally, firms have been dependent on internal sources such as their own employees – and up to a certain extent, on some external sources, their customers – for innovation. However, in the current scenario of technological dynamism, firms are exploring multiple sources to generate ideas for innovation. Therefore, there is a need to understand the relative effect of various sources of innovations on a firm’s performance.

Methodology/approach

We offer a conceptual framework where we identify six distinct sources of innovations – firm, customers, external network, competition, macro-environment, and technology and how they create value for focal firms especially their brand equity. We introduce a taxonomy of various costs and benefits related to innovations. We then argue using our proposed taxonomy to understand the relative strengths of various sources of innovation affecting a firm’s brand equity.

Findings

We discuss and compare the relative effects of these sources of innovations on a firm’s brand equity by rank-ordering the sources. The customers and the technology as a source of innovation have the maximum impact on the firm’s brand equity followed by the marginal impact of macro-environment and external network of a firm. The firm itself has a moderate impact on its brand equity, while competition has the minimal impact. Further, we also discuss how the relationship is moderated by different innovation characteristics (nature and type of innovations).

Practical implications

The main practical implication is to create awareness among managers about various costs and benefits of the proposed six sources of innovations and their effects on brand equity. Managers would be able to prioritize their sources of innovation based on firms’ current needs, and whether to focus on lower costs or building higher brand equity in the scarce resource environment.

Originality/value

We offer a comprehensive list of six sources of innovation, build a conceptual framework wherein we discuss the relative strengths of these sources affecting brand equity.
