In this paper, the maritime industry’s commitment to green supply chain has been analyzed. The objective of this study is to show that the reuse of empty containers not only adds value to a firm, but leads to waste reduction in the supply chain. The novelties of this article include (i) empty and laden containers are treated in accordance with a shipping company’s green effort; (ii) both the volume and weight of containers are introduced to indicate a potential constraint on green effort; (iii) empty container storage costs are included as a value-added component which stem from green effort.  相似文献

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain.  相似文献

The role of product architecture modularity is commonly in increasing product reusability and minimizing waste. This paper designs a decision support system to determine optimal product architecture modularity in closed loop supply chains. The objective is to investigate if remanufacturing and modular upgrading is appropriate at certain periods and in modules. The optimization model is tested under several production yield scenarios in order to determine manufacturing and remanufacturing capacity and production line scheduling under process yield uncertainty. The implications of product architecture modularity for operations economy of green supply chains are discussed in terms of their theoretical and managerial aspects.  相似文献

To meet green supply chain management’s requirements of a company and its transportation service providers (TSPs), it is essential to set clear, achievable, and realistic targets. This paper proposes two data envelopment analysis (DEA) approaches to find targets for two-stage network structures. The objective of proposed approaches is to plan in feasible region. The feasible region specifies bounds to ensure targets are within current operational capacity of TSPs. Applying the approaches to set targets for 24 TSPs lead to different results. However, proposed models ensure that the TSPs would be efficient in their current capacity.  相似文献

This study aims to understand how buyer–seller relationship, competitive environment and guanxi affect Chinese manufacturers’ decision to implement Green Supply Chain Collaboration (GSCC). We also examine whether guanxi is able to mediate the buyer–seller relationship and GSCC implementation. Data collected from 222 Chinese manufacturing organizations were analyzed using the partial least squares method of structural equation modeling. The result shows that buyer–seller relationship influences Green Supply Chain Collaboration through asset specificity, volume uncertainty, transaction frequency and competitive environment. The results also showed support for our hypotheses that guanxi mediates the effect of asset specificity, volume uncertainty and environmental competition on GSCC.  相似文献

Based on a comprehensive data set of German railway customers we analyze consumers’ choices and particularly subsequent changes of two-part pricing contracts (loyalty cards). In a competing risks framework, we simultaneously estimate effects on three types of contractual events: cancellations, upgrades, and downgrades. Focusing on customer relationship management (CRM) practices, we find several factors affecting these events, some of which railway companies can influence to their advantage. Intuitively, installing auto-renewal procedures for loyalty cards decreases cancellation hazards. However, automated electronic mailings (e.g., reminders and account statements) and advertising (e.g., ticket offers) can be counterproductive and increase the risk of cancellation.  相似文献

Drawing upon the Schumpeterian view of competition and stakeholder theory, the purpose of our study is to examine how issues of rivalry and stakeholder pressure motivate firms to implement green supply management practices. We also consider the role of top management support as an important enabler to how firms react to competitive pressures to pursue green supply management practices. Our model is tested using a sample of supply chain professionals. Our results indicate that environmental pressure from rivals and stakeholders influences green supply management implementation through the mediating role of top management support for environmental initiatives.  相似文献

The aim of this paper is concerned with the design and development of a functional framework for maritime mode integration in European automotive supply chain management when considering outbound distribution. Furthermore, it provides a readjustment of traditional concepts and terminology with findings that the role of ro-ro port terminals should be considered as decoupling points, poles and postponement platforms. Case studies examine relevant Western European ro-ro port terminals for cars and respective links to assembly/factories of vehicles localized in the hinterland and concludes that ro-ro port terminals reduce logistical friction and impedance, as well as promote space/time compression.  相似文献

Building on previous research, this paper establishes a new multi-objective program scheduling model of Logistics service supply chain that considers the uncertainty of operation time for functional logistics service providers (FLSPs) in a mass customization service environment. This model aims to minimize total scheduling costs, minimize the difference between the scheduled and actual time of each service process, and maximize the average satisfaction of FLSPs. Considering the differences in target priority, the goal programming method is applied to solve the model hierarchically. In addition, the effects of scheduling parameters on scheduling objectives are provided after numerical analysis.  相似文献

This paper introduces a research framework to identify barriers from a remanufacturing supply chain perspective including strategic (governmental) and operational dimensions. Using responses from expert practitioners in a truck engine remanufacturer in China, a grey-based Decision-Making Trial and Evaluation Laboratory (DEMATEL) method is applied to examine the cause-effect relationships among various implementation barriers. The results identify that lack of strong financial support for remanufacturing technologies or equipment updates and innovation are key implementation barriers. Lack of quality standards of remanufactured products, adequate availability of used truck engines, and quality guarantee marketing of remanufactured engines are also major barriers.  相似文献

The main objective of this paper is to develop a model to determine the relative efficiency and quality of airports. This factor seems to have a strong effect on the airlines’ choice of hubs. Previous studies of airport quality have used subjective passenger data whereas in this study airport quality is defined from the airlines’ viewpoint. Accordingly, we have solicited airlines’ evaluations of a number of European and non-European airports by means of a detailed questionnaire. Statistical analysis of the median score has shown that these evaluations vary considerably relative to quality factors and airports. The key methodology used in this study to determine the relative quality level of the airports is Data Envelopment Analysis (DEA), which has been adapted through the use of principle component analysis. Of the set of West-European airports analyzed, Geneva, Milan and Munich received uniformly high, relative efficiency scores. In contrast, Charles de Gaulle, Athens and Manchester consistently appear low in the rankings.  相似文献

Mobility and transportation service requirements change with growing age. Also in a car-based society like Germany many seniors need to give up driving the car and are dependent on relatives or public transport. Especially in rural areas, the accessibility of public transport is often limited. Demand responsive transportation has occasionally been proposed by researchers as a viable alternative to stop-, route- and time-based public transportation to address such problems. This case study analyses passenger data from the true DRT system EcoBus to identify distinct drivers of old passengers’ satisfaction compared to other passengers. Contrary to existing literature, older people stated to be even more satisfied with the service then younger travellers did. Moreover, older travellers tend to travel alone, but showed slightly higher satisfaction when travelling in groups. The results suggest that older people might be more open-minded and positive regarding flexible public transport schemes than expected.  相似文献

Airlines from Bahrain, Kuwait, Qatar, the United Arab Emirates and Oman have gained significant market shares in international air transport. Traditionally travellers have chosen hubs like Amsterdam, Frankfurt, London or Paris as transfer points for trips to Asia. With the inauguration of non-stop services to places like Abu Dhabi, Doha or Dubai, new choices for air travellers have emerged. We analyse data derived from German air transport statistics on the effects of passenger flows between the airports of Düsseldorf and Hamburg to Asian destinations. They suggest that services introduced by Emirates stimulated passenger demand for Asian destinations, while incumbent hubs do not lose transfer passengers. Regarding travel times and connection quality of routings between secondary airports in Germany and Asian destinations, comparing routings of Emirates Airlines and Lufthansa suggests that due to geographic and scheduling constraints, services via Arabia do not constitute a perfect substitute for time-sensitive passengers.  相似文献

The geographical scope of travel varies from short distances in urban areas to long distances across cities and countries. While urban travel has been widely analysed in the literature, travel over longer distances and particularly across countries, has received much less attention. While this may be justified due to the number of travellers it cannot be justified when looking at the mileage consumption and its resulting environmental impacts. In this paper, we investigate international long-distance travel preferences related to travel between Scandinavia and Central Europe with particular focus on the Fehmarn Belt fixed link between Germany and Denmark to be opened in 2021. To facilitate long-term demand forecasts for the future fixed link, stated preference data were collected in 2011. Based on these data a discrete choice model for long-distance travellers was developed in order to estimate the value of travel time savings (VTTS). The final model, which was formulated as a nested logit model and included Box–Cox transformed travel time and cost attributes, revealed several interesting findings. Firstly, we found damping effects in both cost and time – most strongly in cost. Secondly, we found significant interactions among travel cost and time, and journey characteristics, such as distance and duration. This had direct impact on the VTTS, which was shown to decrease with distance and duration. Thirdly, we found that air travel implies a higher average VTTS, which is to be expected but rarely supported by empirical evidence.  相似文献

Are museums, galleries and cultural institutions (MGC) educational institutions or accommodations of leisure market? The aim of the present study is to understand why people visit MGCs through analysing a potential link between internet use types and MGC visits. Internet use is categorized into three types: independent activities, recreational activities and social activities. The empirical results indicate that internet use for recreational activities is negatively related to MGC visits, while internet use for independent activities is positively related to MGC visits. The findings suggest that MGCs are expected to provide visitors with educational experience rather than with social or recreational experience.  相似文献

Many airlines use the main deck of aircraft to carry passengers and belly capacity to accommodate cargo and baggage. When problems regarding the weight and balance requirements of the aircraft arise, the cargo is the first to be considered for unloading: a practice is known as “short-shipping”. This paper develops a simulation model for estimating the probability of occurrence of short-shipping. Risk analysis is used to estimate the uncertainty of several factors such as the weight of passengers, baggage, and fuel.  相似文献

This paper aims to draw lessons from retrospectively evaluating the evolution of the air transport discipline right up to the COVID-19 outbreak through the Journal of Air Transport Management (JATM), the main scholarly air transportation journal globally. As such, this study deploys a comprehensive bibliometric analysis and graphical mapping of the JATM knowledge body through CiteSpace visualization of 1483 JATM papers from 2001 to 2019. Our results suggest that while the industry has experienced pandemics and economic crises in the past, both were not dominant in influencing JATM literature neither in frequency nor in impact. That said, recovery, crisis and disruption are important key words in JATM papers not just in regard to safety and economic crisis management but increasingly also related to health concerns with recent key papers published in the pandemic and recovery management context which may have helped the industry dealing with the current crisis as well as current JATM papers on this topic assisting with preparing for a transitioning out of COVID-19 world.  相似文献

This article elucidates how organised tourism initiated by the international tour operator system can involve local actors in a developing country with a young tourism industry. The empirical basis is incoming tour operators in Madagascar with the focus on their policies and practices in getting involved with local tour operators and individual providers of service by the realisation of their programs for international markets. The study adopts a qualitative approach based on personal interviews with incoming tour operators located in the capital city of Madagascar. The central theoretical frameworks applied are primarily from the research literature on partner selection and cooperation in exchange relationships (channels of distribution) and contract theory and the results are discussed within in the wider perspective of local competence development and sustainable tourism. The findings demonstrate that incoming tour operators have a quite limited involvement in the cooperation with local actors and uncover the problems linked to partner-specific, local attraction-specific and context-specific factors. The study offers an insight into a field that has been scarcely illuminated empirically by research and it is believed that the results have relevance beyond the geographical context of the research.  相似文献

Urban commuting has continuously fascinated scholars and decision-makers. As few people live and work in the same place, there is always excess commuting (i.e., the non-optimal or surplus work travel occurring in cities because people do not minimize their journeys to work for most residents). Traditional commuting data sources (e.g., questionnaires and census surveys) are challenged by small samples, high cost, and low spatiotemporal resolution. In contrast, the big social-sensing data (e.g., smart card and mobile phone data) only consider one or two traffic mode of a route, which is not consistent with the real-life condition. This article proposes a framework for modeling excess commuting based on open-source data of the ten most populous megacities in China. We downloaded residential points of interest (POIs) from Lianjia Real Estate website and obtained workplace POIs from China's AMAP, which is widespread used as Google map. The stratified sampling approach was employed to derive commuting pairs. Both commuting distance and time were obtained by the shortest path under public transportation from AMAP. Then, the linear programming method was employed to calculate the theoretical minimum commuting time and distance of each city. We analyzed the statistical property and spatial distributions of excess commuting and found that (1) commuting distances and time (ranging from 9.1 to18.1 km and from 44.8 to 74.3  minutes) of all ten megacities follow a left-skewed normal distribution; (2) in terms of commute cost, all cities show universal core-periphery patterns where the spatial heterogeneity of the commuting time is more significant than that of distance; (3) for each city, the excess commuting measured by time (i.e. from 0.61 to 0.79) is lower than that measured by distance (i.e. 0.68 to 0.89); and (4) the role of mixing land use, waterbody distribution, and centripetal urbanization on urban commuting distance and time is significant.  相似文献
