濮城油田高含水开发后期剩余油分布规律研究与挖潜

本文通过对濮城中渗复杂断块油藏进行剩余油分布规律的研究,从微观、宏观两个方面详细描述了高含水后期油藏剩余油分布特征,对剩余油潜力进行再认识,在此基础上,对不同的剩余油存在类型,提出了分类油藏不同的挖潜技术对策,在重组、建立、恢复注采井网的基础上,进行有效地层间调整挖潜,改善多油层非均质油藏后期开发效果,使水驱采收率得到了提高,水驱效果不断得到改善。     

我国公共租赁房的租金定价模型

公租房补充和完善了我国保障性住房制度,但如何制定合理的公租房租金标准,才能促进公租房健康可持续发展显得尤为重要。公租房租金制定应遵循一定的原则,即成本回收、差别定价和可持续性原则。     

服务补救满意研究

回顾了现有服务补救满意前置因素特别是感知公平的研究成果,进一步推断出应如何感知公平,并借鉴预期失验范式和公平理论建立服务补救顾客满意模型。通过模拟情景问卷数据对模型进行实证检验,结果表明,分配公平和过程公平是服务补救满意的直接前置因素,顾客很可能通过补救结果和过程方面的预期表现失验形成感知公平。     

The customer consequences of returns in online retailing: An empirical analysis

Pressure continues to build on the operations management function to facilitate system and firm level benefits. In the online marketplace, one area of growing interest is that of product returns. Though commonly viewed as a cost center from an operations perspective, operations’ actions have the potential to strongly influence future customer buying behavior in several ways. Using an archival database of actual purchase and returns history provided by a moderately sized online retailer, this study examines the relationship between a customer's experience of product returns, and subsequent shopping behavior. Employing transaction cost, consumer risk, and procedural justice theories, we demonstrate that the returns management process, rather than being regarded as an afterthought to the production and deployment of goods, can significantly and positively influence repurchase behavior. Additionally, we provide evidence that certain customers should be considered for prioritization in the returns process. We suggest ways through which operations managers can take care in discharging their responsibilities in this area – to make returns processing more than simply a “necessary cost of doing business” rather, using it to their advantage in engendering repeat and increased purchase behavior.     

De-hubbing of airports and their recovery patterns

The paper analyzes cases of de-hubbing in air transport between 1997 and 2009. It initially addresses the conditions to be met for airports to be identified as de-hubbing cases. Second, it examines what happens after de-hubbing by clustering the cases into homogenous groups that show that, on average, airports that experienced de-hubbing did not recover their original traffic within five years and that de-hubbing is likely to be irreversible. When hub carriers were replaced at least partially by low-cost carriers, airports on average recovered faster. De-hubbing adversely affects the number of destinations served less severely than the seats offered by carriers.     

Collaboration decisions on disruption recovery service in urban public tram systems

This research focuses on the decisions on recovery services to deal with short-term disruptions in public tram systems. The disruption recovery approach used in Munich, Germany - the best service acclaimed by the public, is adopted as the basis to examine whether to collaborate with a taxi company to provide the recovery service and how to price to compensate the service. The two involving parties’ decision functions with the taxi’s average arrival time as the leading decision variable are formulated and analyzed. Both theoretical and numerical sensitivity analyses are conducted to shed lights on the critical factors affecting the decisions.     

基于变权模糊综合评判的装备抢修备件重要度评估

为科学合理地评价抢修备件重要度,文章在分析影响抢修备件重要度的各种因素基础上,建立了评价指标体系。由于常权模糊综合评判难以体现单项指标变化对备件重要度的影响,论文应用变权综合评估方法,并通过实例证明了变权方法的优越性。
