基于参数优化的物流需求灰预测研究

在当前大力发展物流业的同时,需要做好物流需求预测,从而为各地科学合理地制定物流发展规划,实现物流系统供需平衡提供重要决策依据。物流系统是典型的灰色系统,文章利用江苏省物流货物周转量历史数据建立新陈代谢GM（1,1）模型群,并对模型参数进行优化,通过对模型群中不同维度的各个模型进行比较,选取其中精度较高的模型对货物周转量进行预测。结果表明模拟与预测效果均很好,模型有较高的应用价值。     

Preferences for alternative fuel vehicles of company car drivers

Costs of car ownership for company cars drivers and private car owners are very different. Car use, car choice decisions and preferences for car characteristics may therefore differ substantially between these two markets. In this paper, we present results of a study on the preferences of company car drivers for alternative fuel vehicles and their characteristics, based on data from an online stated choice experiment in the Netherlands. Results show that, assuming current car characteristics, preferences for alternative fuel vehicles, and for electric and fuel cell cars in particular, are substantially lower than those for the conventional technology. Limited driving ranges, long recharge/refuelling times and limited availability of refuelling opportunities, are to a large extent responsible for this. Preferences for alternative fuel vehicles increase considerably with improvements on these aspects, especially for the hybrid and flexifuel car. Under the current company car tax system in the Netherlands, which favours cleaner technologies, these two car types are even preferred to the conventional technology, assuming equal catalogue prices and personal monthly cost contributions. Comparing results with those from a similar choice experiment among private car owners shows that willingness to pay patterns for AFV improvements regarding driving range, recharge and refuelling times, fuel availability and diversity in AFV supply, are considerably different for company car drivers than for private car owners. Company and private car drivers may therefore react (very) differently to future improvements in AFV technology and fuel availability. We finally show that preferences of company car drivers for fuel cell and electric cars depend to a large extent on annual mileage. Market share simulations show that potential early adopters of electric and fuel cell cars can be found among people with a relatively low annual mileage.     

Social-demographics, driving experience and yearly driving distance in relation to a tour bus driver’s at-fault accident risk

This study explored the at-fault accident risk of tour bus drivers based on 2023 drivers in Taiwan. Of the observed drivers, 4.1% had at least one accident in a year period, of these, 68.7% were at-fault for the accident. The results of logistic regression model revealed that a driver’s driving experience was the most influential factor (Wald = 32.291, p = 0.000) leading to at-fault accident risk. Drivers whose driving experience was from 6 to 8 years possessed the lowest at-fault accident rate (0.9%), which was lower than the over-all average at-fault accident rate of 2.8%. Novice drivers whose driving experience less than 3 years had the highest at-fault accident rate (12.4%). The driver’s yearly driving distance and the use of an Automatic Vehicle Location (AVL) system were also significantly associated with a driver’s at-fault accident. However, a driver’s age and educational level were not significantly associated with at-fault accident.
