基于变权法的FPSO原油舱火灾风险综合评价

建立FPSO原油舱清洗作业风险评价体系,对清洗过程中的火灾风险进行评价,为决策者应对风险提供科学依据。在使用层次分析法计算原油舱清洗火灾风险评价体系中各指标权重的基础之上,引入变权法,对得到的常权进行微调处理,使综合评价结果更接近实际。依据"海洋石油113"号洗舱作业数据,分别用层次分析法和变权法进行权重计算,并将综合评价值进行对比。分析结果显示:FPSO原油舱火灾风险综合评价体系引入变权法后,评价结果能通过评价值分布状况来调整各指标在综合评价体系中的作用,而且可以突显评价值相对较小的指标对综合评价值的影响,从而为制定风险应对措施提供新思路。     

Scheduling decision styles on leisure and social activities

This paper investigates scheduling decisions associated with different types of leisure and social activities. Correlations among decisions and self-selection biases are explicitly investigated by using a sample selection model with a bivariate probit selection rule. A dataset collected in the first wave of a recent activity-travel scheduling panel survey carried out in Valencia (Spain) was used for empirical investigation. Significant differences are revealed in the empirical models for leisure and social activities in planning decisions, including different effects of temporal, companionship and demographic factors. The findings of the empirical model have important implications to travel behavior and activity-travel scheduling model developments. These results confirm the existence of different mechanisms underlying the activity-travel decision processes when leisure and social activities are of concerns. Results provide significant insights into enhancing the performances of an activity scheduling model by capturing accurate activity-travel scheduling tradeoffs in flexible activity types e.g. leisure and social activities.

Investigating the predictive performance of computational process activity-based transportation models

The aim of this paper is to achieve a better understanding of computational process activity-based models, by identifying factors that influence the predictive performance of A Learning-based Transportation Oriented Simulation System model. Therefore, the work activity process model, which includes six decision steps, is investigated. The manner of execution in the process model contains two features, activation dependency and attribute interdependence. Activation dependency branches the execution of the simulation while attribute interdependence involves the inclusion of the decision outcome of a decision step as an attribute to subsequent decision steps. The model is experimented with by running the simulation in four settings. The performance of the models is assessed at three validation levels: the classifier or decision step level, the activity pattern sequence level and the origin–destination matrix level. The results of the validation analysis reveal more understanding of the model. Benchmarks and factors affecting the predictive performance of computational activity-based models are identified.     

川藏铁路康定至昌都段地质灾害区域危险性评价

为了评判地质灾害对川藏铁路工程的影响,针对康定至昌都段地形高差大、地灾速度大、地灾规模大、构造活动强的特点,通过对现场调查和分析,将地质灾害区域危险划分为低危险区、中危险区、高危险区和极高危险区4个等级。根据灰色聚类理论,将影响线路工程的主要地质灾害归纳为崩塌-滑坡、泥石流和断层破碎带灾害,采用标度法构建判断矩阵,运用层次分析法构建地质灾害区域危险性分区模型,并将该模型运用于康定至昌都区域的地质灾害危险性分区。研究结果表明,康定至昌都区域工程地质灾害主要为高危险区,在进行工程建设时应适当提高标准,以抵御地质灾害的影响。
