Rail is a significant capital asset for railway companies. It contributes more than half of the capital assets of railway infrastructure. Recent rail inspection data using Ultrasonic rail testing has shown increasing number of rail defects, failures and causing disruptions to rail services. This cost can be further increased when the track quality is poor. In recent years, railroads have been purchasing over 500,000 tons of rails per year at an estimated total cost of US $1.25 billion for replacement of worn out and degraded rails. Rail grinding is considered as viable means in reducing the impacts of rail defects and failures. Rail grinding can result in improved curving performance (wheel/rail interaction) and prevents crack initiation and propagation of surface cracks due to RCF. This paper focuses on analysis of rail degradation process and development of mathematical model considering technical and economic decisions in rail grinding to rail infrastructure owners.

Mean residual life is one of the most important characteristics that can be used to measure the reliability of parallel systems. In literature, mean residual life of parallel systems has been defined in different ways. How are these mean residual life functions related to each other? To answer this question, this paper studies the mean residual life of parallel systems from the point of view of change point, at which the mean residual life function changes its trend. Different definitions of the mean residual life of parallel systems are reviewed and introduced. By comparing the change points of these mean residual life functions graphically, we find that these change points behave in a regular pattern, and all of them are related to the change point for single components in the aspect of location. These results are helpful in the determination of optimal burn-in time.

Preliminary risk analysis (PRA) is a methodology used in critical systems safety studies. It is primarily used at the preliminary stage of the system¿s design so as to determine the scenarios of potential accidents, to evaluate their probabilities of occurrence (frequency) as well as the severity of the resulting consequences and to propose solutions (preventive and/or mitigative safeguards) in order to reduce the risk level in terms of severity/occurrence (to reduce the frequency of the contributors or reduce the severity of the accident). The preliminary risk analysis was largely used in several industrial fields (aeronautics, weapons systems, chemistry, railway...) in order to study the safety of the systems. From one field to another, from one expert to another, many extremely different approaches and methods are used to carry out this analysis. Moreover, the formats representing the results of the PRA are often varied as well as the terminology and the concepts related to the PRA. The main goal of this paper, completed within the framework of project ANR-PREDIT-SECUGUIDE, is to propose a PRA method and to determine standard contents of PRA to be used in the context of the railway systems.

Healthcare service industry is one of the fast growing service sectors in Taiwan. Customer satisfaction and patient-oriented service are becoming important issues and playing significant roles on establishing sustainable strategies. Due to lack of a systematically effective method of identifying patients¿ needs and voice, in this paper, we present an integrated methodology of Kano model and quality function development (QFD). Firstly, Kano model is applied to identify customer needs, and calculate customer satisfaction coefficient that helps the manager to prioritize the importance of service qualities that can increase customer satisfaction. Then, by following the same procedures for product design the four phases of QFD are used to translate the voice of the patients¿ needs into the regular service planning. With this methodology, managers can straightforwardly identify and prioritize what customers need. The steps described here are practical procedures for improving and upgrading healthcare service. Furthermore, the results can facilitate the managers to develop sustainable strategies.

Vegetable is an important agricultural export products of China. Japan is the one of main export countries of Chinese vegetable trade. Over the past few years, the technical barrier trade becomes the main reason to prevent our agricultural products from the exports to Japan. The paper employs the gravity model to do an empirical analysis using the data of Japan and Chinese from 2003 to 2006, then applies to Chinese vegetable exports trade and puts forward some policy suggestions. The domestic manufactures need to raise product quality as much as possible, and the government also needs to work out quality standard beneficial to protecting consumer actively. The higher the standard of China, the closer the Chinese standard with import countries, the more can China promote export.

ERP systems acquisition is an organisational issue since it brings in a new environment. This not only changes the way process is handled (process re-engineering), but also influences the organisation¿s culture and people. ERP imposes technology-driven environment with an aim to enhance process productivity, information integration and user interfaces. Research indicates many ERP projects still ¿fail to deliver¿ results due to organisational complexities instead of commonly perceived technology dimensions. In this paper a framework is discussed to understand the ¿readiness¿ in an organisation. An ERP acquisition is said to be successful if it is put to effective use and benefits are achieved as expected. Organisation¿s ¿readiness¿ is essential to manage these issues and the ¿readiness¿ should be well planned before initiation of ERP systems acquisition. The framework is applied to a dairy processing unit over a period of time during which ERP system was acquired and impact of ¿readiness¿ is observed.

Focusing on formal project management initiatives (PMIs) in the information technology (IT) sector in China, this paper first examines possible differences in perception about such PMIs between IT professionals who were exposed to their implementation and those who weren¿t. This part of the investigation is based on an adaptation of Rogers¿ theory of diffusion of innovations. Second, this paper examines the implementation of PMIs and their possible effect on IT projects. This part of the investigation focuses on ¿inside¿ project management risks and performance. Findings from a survey of 82 senior IT professionals show some differences in perception between the two groups of respondents. Findings show also that organizations that have implemented PMIs tended to better control the ¿inside¿ risks related to the management of IT projects and to report higher performance levels on such projects. The implications for research and practice are discussed.

With the growing awareness of human activity on global climate change, the pricing of carbon emissions would inevitably become reality in Asia as it is in Europe. This paper critically analyzes the possible environmental challenges on supply chain management at the strategic level and the possible paradigm shift. We investigate how environmental factors such as carbon emission affect the supply chain architecture and change its landscape. We predict that green supply chain would bring a paradigm shift in supply chain management. Higher level of horizontal integration is expected to see among suppliers, manufacturers and logistics service providers, and geographically the supply chain would start to contract after the ruthless expansion in past two decades. These predictions would help manufacturers, suppliers, and logistics service providers adjust their supply chain strategies in this shift.

An organization such as a Local Economy and Employment Promotion Agency (LEEPA) needs a proper management system enabling tangible results to be obtained. Even so, it has made great progress in the implementation of continuous quality techniques by using inadequate management models due to its complex structure and status as a public entity. Thus it has a high number of indicators which only cause greater difficulties when it comes to establishing conclusions, and management is oriented towards processes when the usual working method is project management. In this paper, the main features of a series of models have been described and their application to the LEEPA has been analyzed by seeking the deficiencies and proposing or designing improvements. The final aim has been achieved by the definition and use of the so-called Single Employability Indicator; a single parameter from which to obtain conclusions concerning the financing of the whole Organization. The drafting of a new Process Map in accordance with the LEEPA¿s activity has made integration of the models studied necessary by obtaining a hybrid model of Process Management and Project Management.

The paper offers a model and analysis of the rental process at a subscription-based business like Netflix. We analyze a priority scheduling scheme, currently in use, that gives priority to light renters over heavy renters and show that, in some situations, it may be more profitable for the firm to give priority to heavy renters. The optimal initial inventory decision is found for a simplified case. Extensions are briefly discussed.
