Safety analysis of rare events with potentially catastrophic consequences is challenged by data scarcity and uncertainty. Traditional causation‐based approaches, such as fault tree and event tree (used to model rare event), suffer from a number of weaknesses. These include the static structure of the event causation, lack of event occurrence data, and need for reliable prior information. In this study, a new hierarchical Bayesian modeling based technique is proposed to overcome these drawbacks. The proposed technique can be used as a flexible technique for risk analysis of major accidents. It enables both forward and backward analysis in quantitative reasoning and the treatment of interdependence among the model parameters. Source‐to‐source variability in data sources is also taken into account through a robust probabilistic safety analysis. The applicability of the proposed technique has been demonstrated through a case study in marine and offshore industry.  相似文献

Today, since a single product is no longer sufficient to cope with the dynamic market environment, firms are trying to provide the integrated offering of products and services. However, despite the importance and utility of product-service integration, a limited approach has been conducted regarding the planning of the strategic management of integrated offering. To deal with this issue, this paper firstly suggests the concept and typology of technological interface in product-service integration. Based on the technological interface, a generic structure of product-service integrated roadmap is developed. Extended from the generic structure, this paper finally proposes the typological configurations of integrated roadmap according to the technological interface and investigates the usage, characteristics, and roadmapping processes.  相似文献

Radical innovation is crucial for a firm’s success, and organisations should promote it. Prior research has argued that human capital is essential for a company’s innovation. However, the direct and indirect effects of Human Resource Management (HRM) on radical innovation have not yet been determined. Therefore, the present paper aims to explore the direct impact of HRM on radical innovation with a content approach and a process approach. It will also examine the mediating effect that learning through an exploration process has on HRM and radical innovation. Using data from 200 medium-sized Spanish industrial firms, our results demonstrate that Strategic Human Resource Management (SHRM) has a positive and direct effect on radical innovation. We also find that an HRM system directed toward change and creativity and SHRM positively support the process of exploration learning, and that competence exploration has a favourable impact on radical innovation. These results indicate that competence exploration mediates the effect HRM systems and SHRM have on radical innovation.  相似文献

The U.S. Department of Agriculture (USDA) tests a subset of cattle slaughtered in the United States for bovine spongiform encephalitis (BSE). Knowing the origin of cattle (U.S. vs. Canadian) at testing could enable new testing or surveillance policies based on the origin of cattle testing positive. For example, if a Canadian cow tests positive for BSE, while no U.S. origin cattle do, the United States could subject Canadian cattle to more stringent testing. This article illustrates the application of a value-of-information (VOI) framework to quantify and compare potential economic costs to the United States of implementing tracking cattle origins to the costs of not doing so. The potential economic value of information from a tracking program is estimated to exceed its costs by more than five-fold if such information can reduce future losses in export and domestic markets and reduce future testing costs required to reassure or win back customers. Sensitivity analyses indicate that this conclusion is somewhat robust to many technical, scientific, and market uncertainties, including the current prevalence of BSE in the United States and/or Canada and the likely reactions of consumers to possible future discoveries of BSE in the United States and/or Canada. Indeed, the potential value of tracking information is great enough to justify locating and tracking Canadian cattle already in the United States when this can be done for a reasonable cost. If aggressive tracking and testing can win back lost exports, then the VOI of a tracking program may increase to over half a billion dollars per year.  相似文献

Martin K. Starr facilitated the creation of an identity for production and operations management (POM) as an academic discipline. This paper aims to summarize Starr's substantial contributions to scholarly inquiry on system integration and interfunctional coordination, modular production, and catastrophe avoidance. Even after four decades, we describe how his legacy in these areas continues to define several major drivers of operations and supply chain management research and practice. Starr has influenced several generations of students, professors, and executives with his writings, teaching, and leadership roles in the POM community that include 32 years on the faculty of the Columbia School of Business, 15 years as Editor‐in‐Chief of Management Science, and presidency of the Production and Operations Management Society.  相似文献
