岩土工程勘察中技术问题分析与对策研究

随着我国经济改革的进一步深入,勘察市场竞争越来越激烈。低价中标使许多勘察单位不愿意采用先进手段和先进设备。近年来,勘察技术进步有停滞不前的趋势。许多与工程密切相关的课题得不到解决。     

并行工程环境下产品开发中非时间冲突研究

文章认为，并行工程中非时间冲突问题的产生是由于开发设计目标与结果不一致、评价标准不同、信息不完整、资源要素约束等原因所致。基于此，文章提出了确保目标一致建立自我矫正机制、合理的组织与设计任务划分、建立信息共享机制、建立设计原理支持系统等并行工程环境下产品开发中非时间冲突问题的解决方案。     

Providing packages of relevant ATM information: An ontology-based approach

ATM information providers publish reports and notifications of different types using standardized information exchange models. For a typical information user, e.g., an aircraft pilot, only a fraction of the published information is relevant for a particular task. Filtering out irrelevant information from different information sources is in itself a challenging task, yet it is only a first step in providing relevant information, the challenges concerning maintenance, auditability, availability, integration, comprehensibility, and traceability. This paper presents the Semantic Container approach, which employs ontology-based faceted information filtering and allows for the packaging of filtered information and associated metadata in semantic containers, thus facilitating reuse of filtered information at different levels. The paper formally defines an abstract model of ontology-based information filtering and the structure of semantic containers, their composition, versioning, discovery, and replicated physical allocation. The paper further discusses different usage scenarios, the role of semantic containers in SWIM, an architecture for a semantic container management system, as well as a proof-of-concept prototype. Finally the paper discusses a blockchain-based notary service to realize tamper-proof version histories for semantic containers.     

Harnessing the wisdom of crowds: Decision spaces for prediction markets

The increased metabolism of business in the modern world has served to heighten both the frequency and the difficulty of organizational decision making. Practitioners and academics are constantly looking for decision-making mechanisms that can be used to address these challenges. One recently emerged mechanism is prediction markets: a group decision-making tool that uses a market mechanism to rapidly aggregate information held by large, diverse groups of participants. Prediction markets have a number of benefits and have been demonstrably successful in a number of contexts; however, it is important to recognize that they are suited to some types of decisions and contexts but not to others. This article examines the benefits of prediction markets and develops a framework that can be used to identify in which situations prediction markets can be profitably deployed within organizations. It also provides a roadmap for practitioners to use to guide their own organizational deployment of prediction markets.

面向港区平面交叉口安全性评价的微观交通仿真模型

本文基于交通冲突技术(TCT),通过建立港区交叉口交通流微观仿真模型,对影响港区交叉口安全性的主要冲突类型进行分析评价。结合港区道路交通特性,仿真模型引入车型参数控制因素,以车辆间冲突制动距离为评价指标,并对大型车辆弯道行驶轨迹及其产生的冲突进行了分析,通过采用改进的二维元胞自动机模型,对车辆在元胞中的加速、减速以及位移规则进行了改进。通过仿真得出,在实验条件下,跟驰冲突是影响平面交叉口安全性的主要冲突类型,侧面冲突是影响交叉口通行能力的主要冲突类型,仿真结果及分析表明了本文交通仿真模型的有效性。
