如何运用现代非线性数学方法研究公共交通车辆调度决策系统

时代在进步,经济在腾飞,交通作为经济的命脉,无可质疑的也产生了翻天覆地的变化与发展,但是就目前来看,我国的交通系统由于人口的基数和居民的私家车的增多,交通的压力日趋增大,如何改善这种状况,是本文旨在研究跟探讨的关键所在,本文主要介绍了非线性代数的数学方式来分析和调度交通的车辆,并由此提出了一套利用智能化指导居民出行的优化方案,从而缓解交通压力,提高决策能力,另外,还介绍了一种运用于调度车辆的遗传算法,便于决策者进行参考和配置。     

基于趋势分解的机场季节旅客吞吐量预测方法

针对机场季节旅客吞吐量的特点,提出了基于趋势分解的机场季节旅客吞吐量预测方法,其基本思想是:首先根据机场季节旅客吞吐量历史数据的移动平均数,计算平均季节指数并进行修正,然后构建机场季节吞吐量趋势变动模型,从而构建航线季节客运需求分析模型。仿真结果表明该方法可行且结果具有较高的精度,可作为预测机场季节旅客吞吐量的有效工具。

Estimating multimodal public transport mode shares in Athens,Greece

We analyze market shares for each public transport mode in total public transport ridership for the multimodal public transportation system of Athens, Greece. This analysis provides useful information for making investment decisions concerning the public transport infrastructure and for allocating subsidies. Due to the non-stationary properties of the data, cointegration techniques are applied to investigate the long run equilibrium relationships. Error Correction Models are implemented to estimate short run dynamics as well as the speed of adjustment from the short to the long run. Results suggest that fare and GDP are the main determinants of the public transport mode shares both in the short and in the long run. Findings also indicate the role of total ridership fluctuations in explaining variations in public transport mode shares.     

Land Transport for Export: The Effects of Cost, Time, and Uncertainty in Sub-Saharan Africa

In Sub-Saharan Africa (SSA), inland export transport costs and time delays are much higher for landlocked countries, vary substantially between different geographic corridors, and exhibit substantial uncertainty. Unit costs and costs of time for land transport of exports are high for many agricultural products relative to metals and other high-value products. We illustrate systemic uncertainty in land and maritime transport for exporting by use of simulation. Relationships among uncertainty, infrastructure quality, and other features of logistics systems are highly non-linear, and can be potentially used to identify priorities for trade facilitation.     

Innovative Practice——Shipping Magnate CY Tung's Road to Success

CY Tung was the pioneer of innovation and the practioner of innovative theories in modern shipping, regardless of his huge oil tanker building, container transport, institutional management or resource integration. Tung, the shipping industry have called the pioneer of innovation, Tung's road to success is a story and history of continuous innovation. In his shipping career, adhering to the innovative concept, multi-use new shipping technology, and management practice, Tung had built a team with the ability to innovate. Tung's group, by integrating its human resources, contacts and production resources ultimately established himself in the highly competitive international shipping market and achieved his legendary of the world shipping tycoon.

Tourism's climate mitigation dilemma: Flying between rich and poor countries

Stronger demand for medium- to long-haul air transport is the main driver of the tourism industry's increasing greenhouse gas (GHG) emissions, causing the current development of global tourism to be environmentally unsustainable. Efficiency improvements and biofuel usage are unlikely to maintain pace with the projected growth in transport volume. Therefore, curbing the growing demand for air transport has been suggested as another option for the sustainable development of tourism. However, the political and industry discourse concerning the restriction of air transport tends to label such a restriction as unethical, as such limits would impair the development that tourism brings to poor countries. This paper investigates the possible impacts of air travel restrictions on the least developed countries (LDCs) and non-LDCs by examining global tourism. The impacts on LDCs are found to be ‘neutral’ on average, with both losses and gains in tourist arrivals. The extent of any losses does not appear to be beyond the scope of possible economic compensation.
