The paper analyzes the impact of e-business technologies on maintenance management and supply chain operations. The aim of this work is to investigate the network organization level of supply chains in case of remote maintenance application and to understand how maintenance policies are coupled with information technology (IT) solutions. To this purpose two literature reviews are presented: firstly, on the supply chain and network integration, and then on the evolution of maintenance using information technology. Following this, the paper present four specific industrial case-studies of eMRO network organisation. They have been chosen as reference models from a set of practical applications and pilot tests performed by the authors in different production sectors in the last 5 years. Technology complexity environments, maintenance outsourcing level, and supply chain integration context are discussed for each case-studies with particular regards to the profitable forms of collaboration provided by the introduction of IT and the Web. This analysis work toward the development of a framework useful to: (1) classify different e-maintenance systems and understand the relationships between the different members of the network, and (2) identify the variables which can influence the introduction and development of the systems. 相似文献

This paper studies the effectiveness of the implementation of trade facilitation measures in member countries of the Association of Southeast Asian Nations (ASEAN). We evaluate trade facilitation performance and indicate trade facilitation needs and priorities that vary between ASEAN members. In particular, we examine logistics‐related costs in ASEAN and whether the current level of logistics‐related costs could be a burden or an advantage for ASEAN countries. We also identify critical barriers that have impacts on logistics services related to foreign investment and customs across ASEAN. Finally, we propose recommendations for the harmonisation of logistics policies in ASEAN countries aimed at the development of the ASEAN Economic Community. 相似文献

Using technological capabilities as embodied in machinery, organization, processes and products, this study examines the links with host-site institutions and regional production linkages. The statistical results show no relationship between these variables. In-depth interviews complement the quantitative findings. Overall, the result shows that the government’s localization efforts failed because too many joint-venture assemblers were approved in the 1990s when the domestic market was small. The lack of economies of scale also affected the growth of national suppliers. Hence, national producers are confined to low value added segments and lack the quality to compete in export markets. 相似文献

This paper compares the weighting schemes in the traditional, principal component and dynamic factor approaches to summarizing information from a number of component variables. To facilitate the comparison, we propose a framework to discuss the approaches with respect to their implied loadings in a latent variable model. We also propose a way to transform the dynamic factor index into an analogous index which is a weighted average of the components. The framework shows the strengths and weakness of the alternative weighting schemes and the sense in which the dynamic factor approach has the advantage of capturing both the significance and the variability of the components. 相似文献

ABSTRACT This article explores the use of marketing metrics by a sample of Vietnamese firms, providing an example of the use of marketing metrics in a “transition” economy as it grows and becomes more market and marketing driven. The analysis reports usage frequency and then develops a set of “correlation chains” linking firm characteristics, metric use, and various indicators of performance. Vietnamese managers generally report that several types of metrics are used. Ownership structure and industry also impact which metrics are utilized. An initial assessment of chains relating metric use to firm performance indicates that the impact is complex and indirect. 相似文献

This paper presents a new Cumulative Sum approach for the detection of turning points in financial time series that are subject to cyclical mean level and volatility regime shifts. The new CUSUM approach is applied to the problem of detecting turning points in hot issue markets for Initial Public Offerings (IPOs), thus providing a multi-dimensional characterization of states of the IPO cycle. 相似文献

As banking markets in developing countries are maturing, banks face competition not only from other domestic banks but also from sophisticated foreign banks. Given the substantial growth of consumer credit and increased regulatory attention to risk management, the development of a well-functioning credit assessment framework is essential. As part of such a framework, we propose a credit scoring model for Vietnamese retail loans. First, we show how to identify those borrower characteristics that should be part of a credit scoring model. Second, we illustrate how such a model can be calibrated to achieve the strategic objectives of the bank. Finally, we assess the use of credit scoring models in the context of transactional versus relationship lending. 相似文献

This paper re-designs the New Keynesian model developed by Ireland (2004) and then uses the Vietnamese data from January 1995 to December 2012 to estimate the model's parameters. The empirical results show that the State Bank of Vietnam had been more aggressive as well as more responsive to aggregate fluctuations in the period before August 2000 than in the latter period. Thus, this change in the policy stance could be a potential reason for the declining importance of monetary policy in generating movements in output growth, inflation, interest rate, and the output gap across the subsamples. Another notable finding is the dominant role of the cost-push shock in explaining fluctuations in inflation, interest rate, and the output gap, leading to a policy implication that more attention should be devoted to developing substitute and complement industries so as to mitigate negative effects of the cost-push shocks by reducing the degree of dependence on imports. 相似文献

We use ARCH time series models to derive model based prediction intervals for the Total Fertility Rate (TFR) in Norway, Sweden, Finland, and Denmark up to 2050. For the short term (5–10 yrs), expected TFR‐errors are compared with empirical forecast errors observed in historical population forecasts prepared by the statistical agencies in these countries since 1969. Medium‐term and long‐term (up to 50 years) errors are compared with error patterns based on so‐called naïve forecasts, i.e. forecasts that assume that recently observed TFR‐levels also apply for the future. 相似文献
