The aim of this article is to propose a decision model based on Analytic Hierarchy Process (AHP) for the evaluation and selection of Logistics Service Providers (LSPs) for a refrigerated products company. The results indicated that quality, responsiveness and reliability are the most important criteria for selecting an LSP for the transportation of perishable refrigerated goods, considering contractor’s profile, which is based on protection of its brand and reputation in the market. In addition, sensitivity analysis is performed to verify priority ranking stability. Therefore, this research illustrates how AHP model could be implemented to help the decision-making process for selecting third-party services in logistics for perishable refrigerated goods effectively. 相似文献

This study aims to propose a hybrid framework for lean six sigma (LSS) based on the prioritisation of barriers and solution approaches, to facilitate hassles free applications for handling the challenges of wastes reduction and quality improvement. The study identifies 27 LSS barriers and 22 solution approaches through literature review and utilises feedback from industry experts. For framework, study uses fuzzy AHP-PROMETHEE to prioritise LSS barriers and solution approaches. Incorporating fuzzy sets in analytical hierarchy process (AHP) ensures the optimality of barrier weights. Whereas, preference ranking organisation method for enrichment of evaluations (PROMETHEE) helps in pairwise comparisons of solution approaches with respect to each LSS barrier, facilitating fair judgements. This research guides regarding the development of framework and checks its suitability and robustness through case application of an Indian manufacturing organisation. Authors expect that researchers and practitioners will find study useful for LSS and multi criteria decision making(MCDM) domains. 相似文献

Three groups of lay opinion leaders were used in a group role-playing decision exercise designed to explore problems in public risk management decision-making. The application domain was possible risks from the 60 Hz electric and magnetic fields associated with high-voltage power transmission lines. While there were differences in the make-up and dynamics of the three groups, the structure and substantive content of the tasks undertaken dominated intergroup variation in terms of the factors that were most important to group members' decisions. The groups displayed sophistication in their identification of decision attributes and in many of the arguments they advanced, but experienced difficulties in structuring and making trade-offs and decisions. The groups were not good at normalizing or otherwise manipulating quantitative information, and used it largely in the form it was received. Upper-bound risk estimates were treated operationally in most group discussions as expected values. Several kinds of strong framing effects were observed in the use of cost and risk information. Specific quantitative results obtained must be treated with care but may provide a starting place for further work on the acceptable level of transmission line risk. 相似文献

The assessment of corporate sustainability has become an increasingly important topic, both within academia and in industry. For manufacturing companies to conform to their commitments to sustainable development, a standard and reliable measurement framework is required. There is, however, a lack of sector-specific and empirical research in many areas, including the sugar industry. This paper presents an empirically developed framework for the assessment of corporate sustainability within the Thai sugar industry. Multiple case studies were conducted, and a survey using questionnaires was also employed to enhance the power of generalisation. The developed framework is an accurate and reliable measurement instrument of corporate sustainability, and guidelines to assess qualitative criteria are put forward. The proposed framework can be used for a company’s self-assessment and for guiding practitioners in performance improvement and policy decision-making. 相似文献

This paper provides a critical analysis of the way that practice-based strategic planning in terms of disaster risk reduction occurs, highlighting the drivers and facilitators of change. It documents these in the context of other governmental systems. Examination the changes to wildfire planning policy in Victoria, Australia, following the 2009 Bushfire Season, provides an explanation of the realpolitik of policy formation, management and change, as well as inter-governmental interactions. The findings document and discuss the conditions and reasons for strategic change occurring in the case study. 相似文献

There is little evidence on unemployment duration and its determinants in developing countries. This study is on the duration aspect of unemployment in a developing country, Turkey. We analyse the determinants of the probability of leaving unemployment for employment or the hazard rate. The effects of the personal and household characteristics and the local labour market conditions are examined. The analyses are carried out for men and women separately. The results indicate that the nature of unemployment in Turkey exhibits similarities to the unemployment in both the developed and the developing countries. 相似文献

This paper proposes a methodology for investigation of the space–time relations of accessibility to public services and collective mobility. The paper assesses the space–time efficiency of local public transport facilities and makes an accessibility analysis as a baseline for evaluating future changes. It explains the potential for improvement and the effects on planning paradigms. Public transport accessibility greatly changes during day and night time so they should be assessed through multi-scaled and diachronic maps as a contribution to the timetable plan and overall planning strategies. The case study of Brescia, Italy is used to test the methodology. The new light rail system of Brescia entered into operation in 2013 and could change the entire form of urban mobility. 相似文献

Energy conservation is an important factor in both sustainability programs and operating costs faced by organizations. The current study used visual prompts, performance feedback, and goals setting to reduce unnecessary classroom lighting on a college campus. A package intervention was applied weekly over a semester using a multiple baseline design across three units, with one unit serving as a baseline-only control. Signs were hung in classrooms and updated weekly. The signs asked users to conserve energy by turning off the lights when the room is not in use, and indicated progress toward a goal for the current room as well as the building overall. The combined treatment successfully reduced unnecessary classroom lighting and generated interest in campus sustainability programs. 相似文献

Uncertainty is a critical factor that pervades all aspects of electric-utility planning. Uncertainties about future load growth, about the continued performance of existing supply and demand resources, and about the costs, construction times, and operations of new resources greatly complicate utility resource acquisition. This paper discusses the factors that lead to uncertainty, reviews the methods that utilities use in planning and in acquiring resources, and suggests future research to help deal with these uncertainties. This review is based on assessments of the long-term resource plans prepared by 10 utilities and one Public Service Commission, telephone interviews with staff at these 11 organizations and with staff at three consulting firms, and reviews of many other related publications. 相似文献

To investigate the extent to which personal values and experiences among scientists might affect their assessment of risks from dioxin, radon, and environmental tobacco smoke (ETS), we conducted an experiment through a telephone survey of 1461 epidemiologists, toxicologists, physicians, and general scientists. Each participant was read a vignette designed to reflect the mainstream scientific thinking on one of the three substances. For half of the participants (group A) the substance was named. For the other half (group B), the substance was not named but was identified only as Substance X, Y, or Z. Knowing the name of the substance had little effect on the scientists' evaluation of dioxin, although those who knew the substance to be dioxin were more likely to rate the substance as a serious environmental health hazard (51% vs. 42%, p = 0.062). For radon, those who knew the substance by name were significantly more likely to consider it an environmental health hazard than were those who knew it as substance Z (91% vs. 78%, p less than 0.001). Participants who knew they were being asked about ETS rather than substance X were significantly more likely to consider the substance an environmental health hazard (88% vs. 66%, p less than 0.001), to consider the substance a serious environmental health hazard (70% vs. 33%, p less than 0.001), to believe that background exposure required public health intervention (85% vs. 41%, p less than 0.001), and to believe that above-background exposure required public health intervention (90% vs. 74%, p less than 0.001). These findings suggest that values and experiences may be influencing health risk assessments for these substances, and indicate the need for more study of this phenomenon. 相似文献

The Business Case for Corporate Social Responsibility: A Review of Concepts, Research and Practice 总被引:1,自引:0,他引:1
In this review, the primary subject is the 'business case' for corporate social responsibility (CSR). The business case refers to the underlying arguments or rationales supporting or documenting why the business community should accept and advance the CSR 'cause'. The business case is concerned with the primary question: What do the business community and organizations get out of CSR? That is, how do they benefit tangibly from engaging in CSR policies, activities and practices? The business case refers to the bottom-line financial and other reasons for businesses pursuing CSR strategies and policies. In developing this business case, the paper first provides some historical background and perspective. In addition, it provides a brief discussion of the evolving understandings of CSR and some of the long-established, traditional arguments that have been made both for and against the idea of business assuming any responsibility to society beyond profit-seeking and maximizing its own financial well-being. Finally, the paper addresses the business case in more detail. The goal is to describe and summarize what the business case means and to review some of the concepts, research and practice that have come to characterize this developing idea. 相似文献

In contrast to the old debate between national and more globally orientated strategies, recent typologies, as outlined by Calori and others in a recent issue of this journal, have begun to uncover subtler international strategies applicable to less patently global industries. This article investigates whether such typologies can be adapted to a service sector such as retailing and analyses performance differences across the whole set of these new categorisations, segregating some of the main sectors. Focusing on clothing where scale economies were lower, we present a case study demonstrating how this approach can still yield strategic insights and recommendations at an early stage in internationalisation, even for players located in more peripheral locations such as Norway. We confirm ‘continental leadership’ strategies (under consideration) can be associated with slightly better profitability for retailers more generally; but we warn that this is riskier for clothing retailers, for whom market share emerges as a less critical driver. The most profitable retail strategy configuration is the bold ‘global shaper’ strategy. However, taking into account the case company’s resource position within the clothing sector, our approach recommends consideration of the ‘quasi-global’ strategic configuration, associated with an improvement of just under 2% return on investment. This perspective also aids ‘strategic benchmarking’ (illustrated against high performers H&M and Zara), setting an agenda for operational improvements. 相似文献

This article analyzes the mechanisms and effects of innovative financial instruments that a central public administration (CPA) may adopt to minimize the flood risk in particularly exposed regions. The pattern we suggest assumes that in risky areas the CPA can issue two financial instruments, called project options and CAT‐bonds, producing a dynamic interaction among three types of agents: the CPA itself, the local public administrations, and private investors. We explore the possible scenarios of such interaction and the conditions under which the CPA's goal of maximal risk reduction is attained. This pattern is proposed for flood risk mitigation in the city of Florence, where the model dynamics are tested assuming parameters obtained from engineering studies. 相似文献

Whether on grounds of perceived safety, aesthetics, or overall quality of life, residents may wish to be aware of nearby energy sites such as nuclear reactors, refineries, and fracking wells. Yet people are not always accurate in their impressions of proximity. Indeed, our data show that only 54% of Americans living within 25 miles of a nuclear site say they do, and even fewer fracking-proximal (30%) and refinery-proximal (24%) residents respond accurately. In this article, we analyze factors that could either help people form more accurate perceptions or distort their impressions of proximity. We evaluate these hypotheses using a large national survey sample and corresponding geographic information system (GIS) data. Results show that among those living in close proximity to energy sites, those who perceive greater risk are less likely to report living nearby. Conversely, social contact with employees of these industries increases perceived proximity regardless of actual distance. These relationships are consistent across each site type we examine. Other potential factors—such as local news use—may play a role in proximity perception on a case-by-case basis. Our findings are an important step toward a more generalizable understanding of how the public forms perceptions of proximity to risk sites, showing multiple potential mechanisms of bias. 相似文献

This paper examines supply chain design strategies for a specific type of perishable product—fresh produce—using melons and sweet corn as examples. Melons and other types of produce reach their peak value at the time of harvest; product value deteriorates exponentially post‐harvest until the product is cooled to dampen the deterioration. Using the product's marginal value of time (MVT), the rate at which the product loses value over time in the supply chain, we show that the appropriate model to minimize lost value in the supply chain is a hybrid of a responsive model from post‐harvest to cooling, followed by an efficient model in the remainder of the chain. We also show that these two segments of the supply chain are only loosely linked, implying that little coordination is required across the chain to achieve value maximization. The models we develop also provide insights into the use of a product's MVT to develop supply chain strategies for other perishable products. 相似文献

Two models have been proposed to explain why two groups of workers who have the same level of productivity can receive different wages: (i) the statistical discrimination model, according to which the discrimination is the result of a rational response to uncertainty about productivity that consists in adopting certain characteristics as proxies for productivity and (ii) the taste‐based discrimination model, according to which the discrimination is based on prejudice against a particular group. It is usually difficult to determine empirically whether the gap in earnings is due to statistical or taste‐based discrimination. However, the conditions for a natural experiment were created in 1989 when Israel introduced a licensing examination for immigrant physicians arriving from that point onward, thus making it possible to determine which type of discrimination is responsible for the wage gap between immigrant and native physicians. Controlling for other factors, the paper finds that: (1) the earnings of physicians who immigrated to Israel after 1989 are significantly higher than those of physicians who immigrated previously and (2) the earnings of immigrant physicians who have taken the licensing examination converge to those of native physicians after an average of 5.5 years. These results constitute evidence that the difference in earnings between native and immigrant physicians is due to statistical, rather than taste‐based, discrimination. 相似文献
