Maintaining the performance of infrastructure-dependent systems in the face of surprises and unknowable risks is a grand challenge. Addressing this issue requires a better understanding of enabling conditions or principles that promote system resilience in a universal way. In this study, a set of such principles is interpreted as a group of interrelated conditions or organizational qualities that, taken together, engender system resilience. The field of resilience engineering identifies basic system or organizational qualities (e.g., abilities for learning) that are associated with enhanced general resilience and has packaged them into a set of principles that should be fostered. However, supporting conditions that give rise to such first-order system qualities remain elusive in the field. An integrative understanding of how such conditions co-occur and fit together to bring about resilience, therefore, has been less clear. This article contributes to addressing this gap by identifying a potentially more comprehensive set of principles for building general resilience in infrastructure-dependent systems. In approaching this aim, we organize scattered notions from across the literature. To reflect the partly self-organizing nature of infrastructure-dependent systems, we compare and synthesize two lines of research on resilience: resilience engineering and social-ecological system resilience. Although some of the principles discussed within the two fields overlap, there are some nuanced differences. By comparing and synthesizing the knowledge developed in them, we recommend an updated set of resilience-enhancing principles for infrastructure-dependent systems. In addition to proposing an expanded list of principles, we illustrate how these principles can co-occur and their interdependencies.  相似文献

Not only ETO (Engineering to Order), but even serial production industry should know how to deal with projects and their schedule: plant commissioning, shutdown, introducing new products and similar circumstances should be managed with adequate planning and resource allocation techniques to create a schedule useful in decision making during the execution. The current complex reality, with evolving technologies and fierce pressure to reach the market as soon as possible, pushes the project managers to use more advanced techniques than waterfall planning, such as agile or lean. It also requires them to take a holistic view and manage concurrent tasks in complex projects. The contributions of this paper are two: the proposal to control specific parallel groups of waterfall activities under uncertain environments, which can lead to iterations and reworks, as a single concurrent Activity Managed by Kanban Methods (AMKM). This activity can be subsequently embedded into traditional scheduling approaches as CPM-PERT. The second contribution is the feasibility of its application in industrial environments due to the affordability of simulation software. Two use cases are shown as evidence. It is not a disruptive proposal, but a kaizen action based on very mature technologies. Finally, it is suggested some improvements to be implemented in Project Management Software due to this ‘kaizen’ proposal.  相似文献

为研究远海岛礁渔获冷链物流的运行方案,本文选择了岛礁冷库储存中转和海上直接收购等两种不同的渔获运输方式,同时考虑了中转冷库选址、中转运输和直接收购船舶配备、航线配置、在渔场停留时间和渔获运输损耗等诸多复杂问题,构建了远海冷链物流体系组合优化模型。求解时,提出了一种以遗传算法(GA)为外部框架,以改进的模拟植物生长算法(PGSA)为内部模块,通过信息传递实现内外连接交互的集成算法。最后,以我国南海远海岛礁及渔场为实例进行分析,取得了较好效果。通过与传统遗传算法对比,本文优化结果、稳定性及计算速度等均有明显提高,从而证明了本文所建模型与算法的合理性和有效性。  相似文献

对于推动我国农村电商与农村物流发展,政府政策支持与引导至关重要,政府减贫战略目标的实现依托于农村电商与农村物流协同主体决策。分别构建政府、企业、农村电商与农村物流协同演化博弈模型,探讨协同系统发展参与主体均衡策略选择,分析政府减贫策略下农村电商与农村物流协同演化博弈稳定性,通过收益矩阵分析得出均衡策略和稳定性因素。结果表明:政府对企业的策略选择是影响企业决策的重要因素,政府积极推进策略有利于农村电商与农村物流协同合作演化;农村电商与农村物流协同减贫策略决策、投入成本对系统演化具有重要影响。政府“减贫”、农村电商“线上协同”、农村物流“线下协同”是现阶段政府减贫下农村电商与农村物流协同发展最优模式。  相似文献

Abstract

The Millennium Development Goals (MDGs) are often critiqued as a strategy of social engineering. This analysis would seem to be supported by the case of the Millennium Villages Project (MVP), the world's leading programme for the achievement of the MDGs. At the level of its discursive articulation, the MVP appears as a scientific ‘proof of concept’ for the comprehensive engineering of neoliberal social orders. But its evaluation methodology has been widely criticised for a lack of scientific rigour, and field research that I conducted in the Ruhiira Millennium Village in Uganda in 2013 revealed serious problems of implementation. I argue that the MVP is better understood not as a strategy of social engineering but as the staging of a social fantasy in which the constitutive antagonisms of capitalist development are concealed. In this fantasy space, the MDGs function to fill the gap between the promise of development and the impossibility of capitalism without poverty.  相似文献
