知识管理视角下的项目风险管理过程与集成   总被引:2,自引:0,他引:2  
项目风险的实质是缺乏预测未来不利事件的足够知识,这些知识包括知识的缺乏、误用、不确定性以及知识管理等方面.除了特定领域的专业知识外,项目风险的分析、评价、控制等本身也是一种特殊的知识.与以往基于过程控制的项目风险管理方法相比,基于知识的项目风险管理把引起风险的知识因素分析和应对风险的知识工作的成本估计引入到通用的项目风险管理过程中来,以实现组织知识管理与项目风险管理的有效集成.  相似文献

Risk evaluation is one of the important elements of international engineering project management. The risk factors of international engineering projects are systematically analyzed from multiple dimension features of the projects. The muhilayer evaluation index system for the international engineering project risk assessment is proposed and constructed, which consists of 8 I-grade indexes and 24 II-grade indexes as policy risk, market risk, resource risk, and technical scheme risk, schedule risk, funding risk, personnel risk and management risk. And then the self-evaluation and benchmarking evaluation methods are applied to evaluate the international engineering project risk, and established the corresponding mathematical models. Finally, a project evaluation example is given to illustrate the applicability and effectiveness of the mathematical models.  相似文献

In this paper, we explore the potential for strategic environmental assessment (SEA) to be a useful tool for banks to manage environmental risks and inform lending decisions. SEA is an environmental assessment tool that was developed to assist strategic-level decision-makers, such as policy-makers, planners, government authorities and environmental practitioners in improving developmental outcomes, aiming to facilitate the transition to sustainable development. We propose that SEA may also be a valuable tool for banks because it has the capacity to provide information about environmental risks at a time when it can be used as an input to bank lending decisions, which can assist banks in making lending decisions with better environmental outcomes. For these reasons, we argue that in some circumstances, and particularly for project finance transactions, SEA may be a more useful environmental assessment tool for lenders than environmental impact assessment, which many banks are currently relying on to help assess and mitigate environmental risks. Furthermore, we suggest that the use of SEA by banks would contribute to the sustainability goals of SEA.  相似文献

The content of risk-based assessment and management and risk-based inspection and maintenance (RBI&M) employed in process plants are addressed in this article. Probabilistic analyses including probabilistic risk assessment developed in the engineering field over the past few decades are reviewed first. Following that, RBI and risk-informed management employed in the nuclear industry and risk-based inspection, maintenance, and other risk-based approaches used in chemical plants as well as their developments are reviewed, respectively. While most of the above were developed and practiced in industrialized countries, the current situation in Taiwan is also mentioned. Special attention is paid to the possibility and difficulties of employing RBI&M in Taiwan’s power and process plants. The difficulties in adopting existing risk-based approaches to inspect and manage Kaohsiung’s underground pipelines are pointed out in particular. Comments are made at the end of the article.  相似文献

This paper addresses the problem of sectoral approach in the formulation and assessment of projects in development co-operation. Sectoral studies and reports often ignore cross-links between aspects covering poverty, gender, culture, social and institutional fabric, and environment. A first important improvement would be to synchronise the execution of the various sectoral studies. Further improvement may be found in the integration of sectoral studies. Two different forms can be distinguished. At a lower level of integration, the studies are required to focus on a common set of alternatives. At a higher level, one single assessment will cover all relevant cross-sectoral aspects. The paper presents some preliminary reflections and experiences by the Commission for Environmental Impact Assessment in the Netherlands on development of a conceptual framework for integration of assessments.  相似文献

Risk perception researchers frequently notice major discrepancies between expert judgment and lay opinion concerning the identity of ‘large’ risks. These discrepancies are particularly disconcerting because they lead to a significant misallocation of scarce resources devoted to public risk management. Yet, democratic decision-making also appeals to many risk perception researchers, and some see such little prospect for a solution thaty they seem close to surrendering to decision-making based on lay risk perception. This article argues that such a ‘grin and bear it’ strategy is also unsatisfactory; that risk perceptions are unstable grounds for decision-making; that expert risk assessment and lay risk perception differ by design rather than accident; that risk experts' search for ‘virtuous lawmakers’ who would make public decisions for the greatest public good is a vain one; that the dissonance risk perception researchers now observe will likely get worse in the new information age; and that risk perception researchers need to return to first principles to find solutions to these dilemmas. In particular, the gap between expert judgment and lay perception will close only when non-experts are permitted and expected to make their own risk management decisions, so far as that is possible, while bearing full responsibility for their choices.  相似文献
