西非铝矾土进口海运供应链风险评估

在分析从西非到我国终端客户的铝钒土进口海运供应链(Bauxit Import Maritime Supply Chain,BIMSC)内部和外部影响因素的基础上,采用故障模式与影响分析(Failure Mode and Effects Analysis,FMEA)和模糊贝叶斯网络(Fuzzy Bayesian Network,FBN)相结合的方法,建立BIMSC风险评估方法的概念框架。采用FMEA辨识潜在的失效模式,并剖析失效原因和后果;根据失效模式潜在的因果关系建立贝叶斯网络;利用三角模糊数处理表征风险参数的不确定性,评估BIMSC风险水平,并进行敏感性分析,确定风险因子排序。研究结果表明,港口操作中的违规操作、违规指挥、货物易流态化和安全管理问题是主要的风险因素。     

Development and prospects of initial alignment method for strap-down inertial navigation system北大核心CSCD

Initial alignment technology is directly related to the navigation accuracy and startup time of the strap-down inertial navigation system (SINS), and has always been regarded as a challenging focal point in the research field of inertial navigation. This paper makes a comprehensive survey of SINS initial alignment technology, briefly introduces the basic principles of initial alignment without latitude, coarse alignment with known latitude and precise alignment, and points out their advantages, disadvantages and applicable conditions. The research and effects of existing initial alignment error suppression techniques are then analyzed and discussed. Finally, according to the problems of existing initial alignment methods and the development requirements of the carrier, the future research direction of SINS initial alignment technology is predicted. © 2022 Journal of Clinical Hepatology.

网络数据融合技术在MITS中的应用研究

探讨了基于传感器网络的数据融合技术在海事智能交通系统(MITS)中的应用问题,为该领域的进一步研究提供一些有价值的思路和见解。基于目前研究遇到的困境,提出将MITS抽象成一个无线传感器网络(WSN),从而可在WSN环境下引入数据融合技术来研究海事智能交通系统中的各种信息处理问题,如船舶的定位与导航以及避碰等;紧接着,总结了现有定位、导航、避碰和船舶安全管理技术研究的现状并分析了存在的主要问题;针对基于GPS的MITS存在的种种弊端,结合各国卫星定位导航系统的建设现状,提出利用MITS内其它元素的信息和多源信息融合技术来实现船舶的相对定位和导航这一新思路;最后,从网络数据融合技术角度出发,具体指出了MITS网络融合系统构建时所必须考虑的一些基本问题,并给出该融合系统的一般性框架。     

Japanese perspective of driver information systems

A perspective view of of Japanese R&D activities of Driver Information Systems is given from the standpoint of developing joint projects by public and private sectors. First, a brief history of the R&D activities is illustrated from above mentioned standpoint. Then, two major projects, AMTICS and RACS, and the social backgrounds of these projects are explained. In order to give a clear idea of both projects some technical details are treated.Based on the history and the present status of the developments, the basic design conceptions of Japanese Driver Information Systems are explained and several factors or reasons which have influenced to the design conception are discussed. Then, the promoting systems of the R&D activities are generally explained and present status of the projects and future problems in developing more advanced systems are also handled. A brief discussion on the establishment of international standard is also mentioned as a final comment.
