锚机绞缆机液压泵组为何罢工

<正>某VLCC配有AKER KVARNER (挪威阿克克瓦公司)生产的锚机绞缆机液压泵组，其型号为HPU 3*190,液压泵组被安装在船艉舵机房。在液压泵组本身机械状况正常的前提下，其出口压力的控制依靠液压泵控制阀块。要解决液压泵组出口压力异常的情况，必须对液压系统各部件的功能和工作原理有清楚的了解。

A NEW TECHNIQUE FOR COMPAIRING FUZZY NUMBERS USING AN INDEX OF OPTIMISM

IntroductionFuzzy numbers,or fuzzy subsets of the realline R,are a convenientconceptfor the representa-tion and arithmetic manipulation of imprecise nu-merical quantities[1,2 ] .In applications,the problemof comparison or ranking fuzzy numbers arises nat-urally.For example,in a fuzzy decision- analysiscontext[3 ] ,comparison of fuzzy expected utilitieslooms imminent.Many methods for comparing two or morefuzzy numbers have been suggested in the litera-ture as surveyed in Ref.[4]. Generally,th…     

基于二维布局分散度的两阶段箱位指派优化

集装箱码头的资源配置优化,是集装箱装卸作业组织的核心.作为集装箱堆场空间资源配置的重要优化指标,提出布局分散度的规划概念.以集装箱码头堆场的箱位指派问题为应用背景,为提高集装箱后续作业效率,分别从堆场布局层面和箱区箱位指派层面考虑多维度布局分散度的优化意义.建立第一阶段为仿真,第二阶段为混合整数二次规划(MIQP)的两阶段优化模型.结合实际码头生产数据进行算例实验,结果缓解了堆场拥堵情况并提高了码头集装箱装卸作业效率.同时,研究也揭示了布局分散度概念在堆场资源优化配置应用中的重要意义.     

A BENCHMARK EXERCISE ON FUZZY SET THEORY BASED EXPERT JUDGEMENT TECHNIQUE

Introduction　　In the areas of every level of probabilistic riskassessment and management in nuclear powerplants,the application of subjective expert' s judg-ments is broadly in demand.The behind reason isprobably thatthe assessmentis usually performed,based on the limited data due to the scarcity of op-erating experience and/or on the incompleteknowledge due to the complexity of phenomenaembedded in severe accidents[1] .In the literature,subjective expert' s judgment is also called expertjud…
