Many executives are currently striving to develop world-class manufacturing operations to ensure that they remain competitive in increasingly global markets. To do this, they are adopting a range of practices, from organisational changes such as empowerment and teamwork to the use of techniques such as pull production. Their goal is to substantially improve performance: faster cycle times, reduced manufacturing costs and greater customer satisfaction.The question of how far companies have moved towards world-class manufacturing is at the heart of the ‘Made in Switzerland’ project, a major benchmarking study of Swiss manufacturing practice and performance. The study was carried out in 1995 by IMD faculty and researchers working with consultants from IBM Switzerland. It is part of the internationally-based ‘Made in Europe’ project comprising similar studies in the UK, Germany, The Netherlands and Finland.The central hypothesis of the studies is that the adoption of best practice leads to high performance. The objective is to establish a benchmarking database for participating manufacturers around the world. The studies, which are highly structured, examine six areas of manufacturing practice and performance in detail and assess the relationship between them at individual plants. The areas covered in the study are quality, organisation and culture, concurrent engineering, logistics, lean production and manufacturing systems.Plants in each country are grouped according to their position on the practice and performance indices and then studied in order to pinpoint the issues and challenges facing the manufacturers within that group. Less than three per cent of the 800 plants currently on the ‘Made in Europe’ database are considered ‘world-class’. Yet for manufacturers striving to reach this level of performance, this small minority can provide some valuable insights for the way ahead.This article discusses many of the issues raised by the analysis described above, with particular reference to the ‘Made in Switzerland’ study. In the first section, it looks at the key lessons arising from the Swiss study and what insights these can provide for manufacturers, not only in the Swiss market, but across Europe. In the second section, it looks at how the study can be used for benchmarking and provides manufacturers with some general recommendations to help them focus their improvements and move closer to becoming world-class.  相似文献

Applications of multivariate statistics in engineering are hard to find, apart from those in quality control. However, we think that further insight into some technological cases may be gained by using adequate multivariate analysis tools. In this paper, we propose a review of the key parameters of rotating electric machines with factor analysis. This statistical technique allows not only the reduction of the dimension of the case we are analysing, but also reveals subtle relationships between the variables under study. We show an application of this methodology by studying the interrelations between the key variables in an electric machine, in this case the squirrel-cage induction motor. Through a step-by-step presentation of the case study, we deal with some of the topics an applied researcher may face, such as the rotation of the original factors, the extraction of higher-order factors and the development of the exploratory model. As a result, we present a worthwhile framework to both confirm our previous knowledge and capture unexplored facts. Moreover, it may provide a new approach to describing and understanding the design, performance and operating characteristics of these machines.  相似文献

Prior to 2007, two systems of bus driver compensation coexisted in Santiago, Chile: one paid drivers per passenger transported, while the other paid a fixed wage. Per‐passenger drivers engaged in “The War for the Fare,” altering their driving patterns to compete for passengers. Examining these systems on similar routes in Santiago, we observed two key findings. Compared with the fixed‐wage system, the per‐passenger system leads to (1) 13% shorter passenger wait times, via reduced bunching of buses and (2) 67% more accidents per kilometer driven, via more aggressive driving. We discuss implications for the design of incentives in public transit. (JEL L92, M52, R41)  相似文献

ABSTRACT

The practice of public relations in Spain began during the Franco dictatorship, which was established in 1939, following a 3-year civil war. The first consultancy was opened in Barcelona in 1960, at the beginning of a period of economic growth due to a change of direction in the regime. After the end of the autarchy and international ostracism, Spain began an unprecedented economic and social transformation. Public relations thus helped businesses to make contact with an ever-better-informed media and public opinion and, in this way, contributed to economic development while simultaneously promoting associationism and improvement in the teaching of the subject.  相似文献

The state is a contested concept in the historiography on early medieval societies. Debates have frequently revolved around its heuristic validity, but few scholars have addressed its broader theoretical implications. Those who have tend to reduce the state to its institutional features and privilege the role of the dominant groups in the analysis of state-building processes and the workings of the state. This paper contends that a richer conceptualisation of the state can overcome the limits of the debate as it has been framed so far and provide a deeper insight into how social relations shaped and were shaped by the development of early medieval polities. After reviewing the most significant historiographical contributions to the debate, the paper introduces the Strategic-Relational Approach to the state, as formulated by B. Jessop, as one that can provide a more nuanced understanding of early medieval polities. Particular emphasis is made on the analysis of class relationships and the articulation of hegemonic projects as two particularly fruitful lines of inquiry. Finally, the paper focuses on one particular instance of early medieval political practice, the politics of the land, as a means to illustrate the potential of the approach.  相似文献

Abstract

Objectives: To evaluate whether daytime sleepiness, poor sleep quality, and morningness and eveningness preferences are associated with common mental disorders (CMDs) among college students. Methods: A total of 963 college students completed self-administered questionnaires that collected information about sociodemographic characteristics, sleep quality characteristics, CMDs, and other lifestyle behaviors. Results: The prevalence of CMDs was 24.3% (95% confidence interval [CI] [21.5%, 27.1%]) among all students. Prevalence estimates of both excessive daytime sleepiness and poor sleep quality were higher among females (35.4% and 54.4%) than males (22.0% and 45.8%). Cigarette smoking was statistically significantly and positively associated with having CMDs (p = .034). Excessive daytime sleepiness (odds ratio [OR] = 3.65; 95% CI [2.56, 4.91]) and poor sleep quality (OR = 4.76; 95% CI [3.11, 7.29]) were associated with increased odds of CMDs. Conclusion: Given the adverse health consequences associated with both sleep disorders and CMDs, improving sleep hygiene among college students is imperative to public health.  相似文献

When Ian Wilson and Carlos Barahona of the Statistical Services Centre at the University of Reading were asked to review an evaluation of the effectiveness of an aid package in Malawi, they expected a simple enough task. But few things in the developing world are simple. Where aid for the poorest is concerned, is evidence collected and analysed with enough rigour to enable well-informed decisions to be made?  相似文献
