With intense global competition, many manufacturing companies pursue a platform strategy to develop diverse products belonging to a family, while utilizing available manufacturing resources. In the past, enormous efforts have been made in investigating product platforms, which exploit platforming potential at the design stage. Researchers have recently discussed new platform concepts, which capitalize on platforming potential at different product family development stages, in addition to investigating more issues pertaining to product platforms. These efforts contribute to the continuous progress on platforming research. This study provides a review of progress on platforming. It identifies and reviews the available platform concepts, including flexible platforms, function-technology platforms, process platforms, and process parameter platforms. It also highlights several trends in platforming research, thus providing an overall picture of platform based-product family development requirements and the corresponding solutions. Based on the review, a framework is presented for future research. © 2015 Elsevier B.V. All rights reserved. Source

Several studies have demonstrated the superior performance of ensemble classification algorithms, whereby multiple member classifiers are combined into one aggregated and powerful classification model, over single models. In this paper, two rotation-based ensemble classifiers are proposed as modeling techniques for customer churn prediction. In Rotation Forests, feature extraction is applied to feature subsets in order to rotate the input data for training base classifiers, while RotBoost combines Rotation Forest with AdaBoost. In an experimental validation based on data sets from four real-life customer churn prediction projects, Rotation Forest and RotBoost are compared to a set of well-known benchmark classifiers. Moreover, variations of Rotation Forest and RotBoost are compared, implementing three alternative feature extraction algorithms: principal component analysis (PCA), independent component analysis (ICA) and sparse random projections (SRP). The performance of rotation-based ensemble classifier is found to depend upon: (i) the performance criterion used to measure classification performance, and (ii) the implemented feature extraction algorithm. In terms of accuracy, RotBoost outperforms Rotation Forest, but none of the considered variations offers a clear advantage over the benchmark algorithms. However, in terms of AUC and top-decile lift, results clearly demonstrate the competitive performance of Rotation Forests compared to the benchmark algorithms. Moreover, ICA-based Rotation Forests outperform all other considered classifiers and are therefore recommended as a well-suited alternative classification technique for the prediction of customer churn that allows for improved marketing decision making. © 2010 Elsevier Ltd.

In France, some institutions seem to call for the engineer's sense of social responsibility. However, this call is scarcely heard. Still, engineering students have been given the opportunity to gain a general education through courses in literature, law, economics, since the nineteenth century. But, such courses have long been offered only in the top ranked engineering schools. In this paper, we intend to show that the wish to increase engineering students' social responsibility is an old concern. We also aim at highlighting some macro social factors which shaped the answer to the call for social responsibility in the French engineering "Grandes Ecoles". In the first part, we provide an overview of the scarce attention given to the engineering curriculum in the scholarly literature in France. In the second part, we analyse one century of discourses about the definition of the "complete engineer" and the consequent role of non technical education. In the third part, we focus on the characteristics of the corpus which has been institutionalized. Our main finding is that despite the many changes which occurred in engineering education during one century, the "other formation" remains grounded on a non academic "way of knowing", and aims at increasing the reputation of the schools, more than enhancing engineering students' social awareness. © 2011 Springer Science+Business Media B.V.

Being able to provide companies with a number of advantages in delivering customised products, product configuration has received increasing attention from the academia and lasting interests from industries in the past several decades. While several surveys and reviews have been reported shedding light on specific issues in product configuration, a general overview is missing. By systematically presenting important concepts, definitions and issues underlying product configuration, such a review is of paramount importance to develop practical solutions, which ultimately contributes to efficient design, development and implementation of product configurators in practice. This study, thus, tries to fill this gap by reviewing the state-of-the-art research on product configuration. It touches on the major issues, definitions and concepts in product configuration along with the corresponding studies, such as configuration ontology, system design and development, and configuration solving. Based on the review, future research is highlighted as well. © 2014 Taylor and Francis. Source

The question of how embedded actors can create institutions that support cluster emergence remains unsolved in the cluster and national innovation systems literature. The present paper extends the recent literature on institutional entrepreneurship and institutional work to solve this paradox of embedded agency in the context of science-based clusters. Building on a longitudinal single case study of a functional foods cluster in Finland, we present an institutional work framework for cluster formation. We argue that, in addition to ideational, material and bridging work, authentic leadership work is critical for cluster emergence. The results of the study highlight the opportunities that scientists have to act as midwives to cluster formation, but they also show that well-functioning clusters need a broader support base. © 2012 Copyright Taylor and Francis Group, LLC.
