程序化交易系统的检测与优化体系

随着国内金融市场的不断发展与完善,程序化交易变得越来越受关注。目前国内大多数程序化交易者并没有建立起一个完备的检测与优化体系,采取的测试方式大多为简单的历史数据回溯测试,这容易导致对历史数据曲线的过度拟合。论文构造出一个较完整的程序化交易系统的检测与优化体系,依次分为六个步骤:设计交易策略,交易策略程式化,验证性检测,交易系统最优化,推进的样本外测试,实战交易。通过此体系可以分析交易模型的风险与收益水平及策略的稳定性,并得出健全的交易策略需具备的特点:获利相对均匀分布、具有相对稳定的盈亏次数比率、具有连续且平滑的最优化参数集、适应不同类型的市场且风险可控。     

Marketing research and revenue optimization for the cruise industry: A concise review

This paper presents a concise review of the cruise industry mainly from marketing research and revenue optimization prospects. In recent years, the cruise industry has experienced an exciting growth. However, as one of the fastest growing and most profitable categories in the entire leisure market, this industry has hardly received any research attention. Given the limited academic articles, this paper presents a concise review about this budding research topic. First of all, a discussion about global cruise industry is conducted. Then, academic studies of the cruise industry on general marketing research, revenue management, itinerary design/optimization, optimal market segmentation, demand infiltration and economic issues are reviewed. Finally, some promising directions for future research are presented.

Optimization Modeling for Logistics: Options and Implementations

Logistics optimization has significantly grown in popularity over the last few decades. Improvements in computing power, modeling software, and the willingness of companies to invest time in the modeling effort have allowed models that were once too unwieldy to solve to optimality to be solved quickly. This has led to a more wide‐spread recognition by logistics managers of the potential advantages of using optimization. The scope of logistics optimization in companies and organizations has expanded to address strategic, tactical, operational, and collaborative decision making. Spreadsheets, an analytical tool familiar to managers, have played a crucial role in the expanded modeling efforts of companies. Although optimization’s role in logistics has grown tremendously, there still are areas that remain to be explored that will allow it to achieve an even larger and more successful role in the management of companies. Additionally, there are some models that are still too large or too complex to currently solve to optimality, despite the advances in computing power and modeling/solving software.     

Disaster‐Relief Logistics With Limited Fuel Supply

Disaster‐relief logistics consists of providing adequate emergency supplies rapidly to the affected people so as to minimize human suffering and death. This study empirically examines the impact that the shortage of fuel, a commonly encountered problem in many disaster situations, can have on the effectiveness of disaster‐relief logistics operations. We focus on investigating the following two issues: (1) whether the shortage of fuel is more damaging in attaining logistical goals than the equivalent‐sized shortage in emergency supplies themselves, and (2) what types of vehicles should be used when the fuel supply is limited. Results suggest that the shortage of fuel may be more damaging than the shortage of emergency supplies, and that smaller trucks may be preferred to larger trucks when the shortage of fuel becomes severe.
