The inherent complexity of supply chains, combined with their economic importance, has prompted research in supply chain management. While there has been a significant amount of work reported in modelling supply chains, the effectiveness of these models in addressing the complex area of supply chain management is questionable. What is giving added urgency to the need for research in this area are the recent developments in communications that offer the promise of connecting suppliers, assemblers and customers in a seamless network of information that can form integrated supply chain management. This paper aims to address the deficiency in modelling by proposing a methodology that models the integrated supply chain as an abstracted network, called a Trans-Net. The Trans-Net approach offers three main potential advantages. First, the multiple participants in a supply chain can be modelled without undue complexity. Second, it is an approach that allows users to examine the interactions between different considerations so that important attributes such as cost and lead-time can be readily calculated and bottleneck areas identified. Third, it applies a mathematical formalism to the problem, with the potential of being relatively straightforward to computerize. 相似文献

Technology adoption is not a new venue for research. Much work of decision modeling, diffusion of new technology and statistical analysis of survey data has been done. Some studies focus on finding the optimal forms of technology to adopt within a complementarity framework, but there is no mention of finding an optimal path from a firm's current state to its optimal state. This represents a significant gap in the literature. The paper applies a constrained shortest path problem to training and technology adoption decisions by firms. Given the current set of training and technology adoption the method solves for what technology/practice should be adopted or removed from the complete set of combinations and in what order so as to maximize performance subject to budget constraints. To the authors' knowledge, this is the first application of the constrained shortest path problem to technology adoption decisions. 相似文献

This interpretive case study sought to fully understand and describe the turnaround experience from an organizational breakdown to breakthrough with the use of Open Space Technology. The turnaround occurred in a Roman Catholic parish. Participant interviews were used to collect the data. These qualitative portrayals provided insights and implications around the effectiveness and impact of Open Space. Four important themes emerged: the experience of breakdown, the deep longing for a breakthrough, the transformation of crisis into a turnaround and the effectiveness of Open Space Technology. This case study provides perspectives on how to effect transformation for an organization in crisis with the least effort and maximum impact within a short time span. It contains insights and implications for leaders and consultants to do the same. 相似文献

与以往大量探讨研发投入影响因素的文献不同,本文从R&D产出效率视角,考察了技术独立董事制度对其的影响。结果发现,我国上市公司增加研发投入并未带来创新水平的显著提高。而聘请技术独立董事的公司能够提升R&D产出效率,并且当上市公司同时设置技术执行董事和技术独立董事时,R&D产出效率更高,但本文没有发现技术独立董事薪酬对R&D产出效率起到激励作用。本文的结论为我国政府和公司制定创新战略以及独立董事制度建设提供了参考价值。 相似文献

We develop an individual behavioral model that integrates the role of top management and organizational culture into the theory of planned behavior in an attempt to better understand how top management can influence security compliance behavior of employees. Using survey data and structural equation modeling, we test hypotheses on the relationships among top management participation, organizational culture, and key determinants of employee compliance with information security policies. We find that top management participation in information security initiatives has significant direct and indirect influences on employees’ attitudes towards, subjective norm of, and perceived behavioral control over compliance with information security policies. We also find that the top management participation strongly influences organizational culture which in turn impacts employees’ attitudes towards and perceived behavioral control over compliance with information security policies. Furthermore, we find that the effects of top management participation and organizational culture on employee behavioral intentions are fully mediated by employee cognitive beliefs about compliance with information security policies. Our findings extend information security research literature by showing how top management can play a proactive role in shaping employee compliance behavior in addition to the deterrence oriented remedies advocated in the extant literature. Our findings also refine the theories about the role of organizational culture in shaping employee compliance behavior. Significant theoretical and practical implications of these findings are discussed. 相似文献

This article introduces a general approach for characterizing cyberinfrastructure resilience in the face of multiple malicious cyberattacks, such as when a sequence of denial‐of‐service attacks progressively target an already weakened information system. Although loss assessment frequently focuses on a single overall measure such as cost or downtime, the proposed technique considers both the timing and the amount of loss associated with each individual attack, as well as whether this loss is incurred suddenly or is “slow‐onset.” In support of this, an underlying mathematical model is developed to represent the relative impact of each attack and the corresponding length of time that its effects persist within the system, as well as to illustrate the trade‐offs between these two factors. The model is extended to represent uncertainty in its parameters and thus to support comparative analyses among various security configurations with respect to a baseline estimate of resilience. Monte Carlo simulation is then used to illustrate the model's capabilities and to support a discussion of its ability to provide for more effective decision making in the context of disaster planning and mitigation.

美国有毒物质排放清单制度的经验与启示简 总被引:1,自引:0,他引:1
有毒化学品排放清单制度首创于美国。美国的经验表明,该制度对于促进环境信息公开是一种行之有效的手段.它能实现环境效益、经济效益和社会效益三者的统一。该制度内容包括有毒物质排放报告、环境应急管理、危险化学品安全管理、环境风险评价等,有毒化学品相关信息公开既是该制度的核心内容也是其最大成功之处。我国应借鉴美国经验,建立类似有毒化学品排放清单的法律制度,有毒化学品数据库的建立和相应信息公开问题,应是下一步立法的规制重点。 相似文献
