Abstract

In recent years, rapid prototyping (RP) and rapid tooling (RT) technologies have been implemented in many aspects of industry, especially in the area of new product development. Based on RP and RT technologies, the paper proposes a rapid design and manufacturing system of the product. There are two ways to develop a new product in this system. One is beginning with a design concept, and another is from a sample as a reference. The reverse engineering technology, transmission processing software or modules of the input data, structure analysis and optimization means and manufacturing process analysis tools were integrated in the system. Some examples show that the integrated system not only can reduce the number of design iterations but also improve the efficiency and reliability of the product design.

Abstract

Purpose

There are many investigations in design methodologies, but there are also divergences and convergences as there are so many points of view. This study aims to evaluate to corroborate and deepen other researchers’ findings, dissipate divergences and provide directing to future work on the subject from a methodological and convergent perspective.

Design/methodology/approach

This study analyzes the previous reviews (about 15 reviews) and based on the consensus and the classifications provided by these authors, a significant sample of research is analyzed in the design for additive manufacturing (DFAM) theme (approximately 80 articles until June of 2017 and approximately 280–300 articles until February of 2019) through descriptive statistics, to corroborate and deepen the findings of other researchers.

Findings

Throughout this work, this paper found statistics indicating that the main areas studied are: multiple objective optimizations, execution of the design, general DFAM and DFAM for functional performance. Among the main conclusions: there is a lack of innovation in the products developed with the methodologies, there is a lack of exhaustivity in the methodologies, there are few efforts to include environmental aspects in the methodologies, many of the methods include economic and cost evaluation, but are not very explicit and broad (sustainability evaluation), it is necessary to consider a greater variety of functions, among other conclusions

Originality/value

The novelty in this study is the methodology. It is very objective, comprehensive and quantitative. The starting point is not the case studies nor the qualitative criteria, but the figures and quantities of methodologies. The main contribution of this review article is to guide future work on the subject from a methodological and convergent perspective and this article provides a broad database with articles containing information on many issues to make decisions: design methodology; optimization; processes, selection of parts and materials; cost and product management; mechanical, electrical and thermal properties; health and environmental impact, etc.

Abstract

Purpose

Measuring texture parameters are time consuming and expensive; it is necessary to develop an efficient and rapid method to evaluate them. Image analysis can be a useful tool. The purpose of this paper is to predict texture parameters in different beef cuts applying image analysis techniques.

Design/methodology/approach

Samples were analyzed by scanning electron microscopy. Texture parameters were analyzed by instrumental, image analysis techniques and by Warner–Bratzler shear force.

Findings

Significant differences (p<0.05) were obtained for image and instrumental texture features. Higher amount of porous were observed in freeze dried samples of beef cuts from Gluteus Medius and semintendinosus muscles. A linear trend with a linear correlation was applied for instrumental and image texture. High correlations were found between image and instrumental texture features. Instrumental parameters showed a positive correlation with image texture feature.

Originality/value

This research suggests that the addition of image texture features improves the accuracy to predict texture parameter. The prediction of quality parameters can be performed easily with a computer by recognizing attributes within an image.

Abstract

Purpose

The purpose of this paper is to explore the current focus of supply chain management (SCM) research; it considers field level and societal constraints and consequently the potential for change. It details the underlying assumptions in the field, considering the dominant paradigms and stakeholders, and how this has shaped the research we have engaged in as a community of scholars.

Design/methodology/approach

This is a reflective inquiry that seeks to deconstruct the dominant discourses and paradigms in SCM. It offers alternative avenues of inquiry to “traditional” research, considering how different questions, perspectives and approaches might yield different learning for the field. offering alternative avenues to traditional research.

Findings

This is a call for collective action, for solidarity, for a re-imagining of what research in SCM could look like. Research activism is challenging and potentially risky but necessary for the research community to engage in, particularly in light of the global societal grand challenges. Change can take place in the SCM field through collective action and solidarity. Three levels of activism are explored here – acting to solve the grand challenges, acting to change the field and acting as individuals.

Originality/value

This is a “speak-out” piece, which embraces and encourages reflexivity, new methods of doing and writing research as well as different perspectives, and especially a consideration for context and multiple players in the supply chain. The authors contend that it is urgent to re-appropriate our own agency as SCM researchers.
