Exploring the motivation and willingness of self-initiated expatriates,in the civil engineering industry,when considering employment opportunities in Qatar

This paper provides empirical and contextual insight into the complexity of Self-Initiated Expatriates’ (SIEs) experiences in a unique setting. Factors that influence SIEs in the civil engineering industry, when considering overseas employment in Qatar, are identified and considered. Drawing comparison to organizational expatriates (OEs), this paper uses semi-structured interviews conducted with professionals from the civil engineering and construction industries. The research surfaced that different factors interconnect to affect individuals’ decisions about overseas employment. Three factors, specifically; location appeal, host country as an employment setting and effect of expatriation on the family, appear to be more influential to participants when the proposed destination is Qatar.

Applying kaizen to the schedule in a concurrent environment

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.     

基于随机p-鲁棒优化的国家血液战略储备库选址-库存模型

以往的救灾实践对建立国家血液战略储备体系提出了迫切要求。国家血液战略储备库的建设问题亟待解决。由于血液产品特性以及应急血液保障特性的存在，使得国家血液战略储备库的选址决策具有一定的复杂性。本文将问题定位为选址-库存问题。首先，以应急条件下血液保障及时度最高为目标，构建了一个不确定环境下考虑多情景、多血型、多阶段、带提前期、有容量限制、日常随机需求、有预算约束及协同定位的国家血液战略储备库选址-库存模型。同时，为了规避应急条件下的不确定风险，进一步构建了国家血液战略储备库选址-库存问题的随机p-鲁棒优化模型。该模型为离散非线性混合整数规划模型，难以快速精确求解。故基于模型性质，设计了相应的遗传算法。最后，设计了两组算例验证模型与算法的有效性。其中，第1组算例基于我国大陆地区31个省级血液中心与省级行政区的数据，并根据不同预算值给出6个算例，得到了国家血液战略储备库的选址-库存决策方案。第2组算例为6个不同规模的模拟算例，用来测试不同规模下的算法性能。算例结果表明：遗传算法的性能更好；鲁棒解与确定性模型最优值相差不大（最大差距≤1.08%），可降低不确定性导致的风险。实践中，可对本文所建模型稍作改进，应用于具有类似特征的易腐品（药品、粮食等）应急物资储备库选址-库存决策。     

Toward General Principles for Resilience Engineering

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.     

胡塞尔“构造”概念的三种图式

“构造”概念是胡塞尔现象学的核心概念，它被用来刻画意义如何向我们显现。索科拉夫斯基认为，胡塞尔分别在静态现象学和发生现象学阶段采取了“静态构造”的形式-质料图式和“发生构造”的一元论图式。笔者将指出，随着后期胡塞尔现象学的推进，构造的含义将更加复杂，它同时指示了自我在世界视域之中的横向结构，以及绝对时间意识支持着世界经验、并与其相互交织的纵向结构。笔者也将在此基础上，提出第三种构造图式。

远海岛礁冷链物流体系优化模型及其集成算法

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。
