基于直觉模糊熵的MBA学生综合能力评价——以模块化培养模式视角

对MBA学生综合能力的评价属于多属性决策问题,评价的目的是考察MBA学生通过模块化培养模式下综合能力的高低。多属性决策问题的特点之一是指标属性的完全未知。通过专家确定的创新能力、机会识别能力、资源整合能力、团队协同能力及解决问题能力等影响因素作为评价MBA学生综合能力的主要指标属性,采用直觉模糊熵方法对MBA学生综合能力进行了评价排序,评价结果有一定的可靠性和可操作性。

电子采购中组合多属性招投标的优化研究

由于物品之间存在互补效应,往往投标者会将几个标的物作为一个组合标进行投标。这一方式在传统的多物品电子采购中仅仅从价格或成本的考虑来确定竞胜标,因而无法同时解决采购中的多属性问题。在网络技术的支持下,这种组合招投标的采购模式已经成为可能。通过以最大化采购方的效用为目标建立数学模型,并运用禁忌搜索算法进行求解,可满足多属性决策的招投标方法要求,解决电子采购中对于具有互补效应的多物品多属性的竞胜标确定问题。但由于问题自身的复杂性,对此类问题的研究处于起步阶段,对于多属性间的关系研究,多属性评价方法的改进,以及求解方法的研究与计算效率的提高等问题还有待于进一步解决。     

基于联系数的三角模糊数多属性决策新模型

针对属性值和属性权重都用三角模糊数表示的多属性决策问题,提出了一种基于联系数的三角模糊数多属性决策评价模型.通过运用集对分析的不确定性系统理论,利用三角模糊数的中值及上下确界所限定的取值区间,将三角模糊数转化为联系数,建立了联系数决策模型,并给出决策步骤,基于此可以对多属性决策评价问题进行排序.该模型的建立既考虑了三角模糊数的中值,又兼顾了三角模糊数的上下确界,即联系数的差异度,更具有客观性.通过对实例的运用和分析表明,该方法算理清晰,计算简便,结论合理.

Valuation Bounds on Barrier Options Under Model Uncertainty

This article investigates valuation bounds on barrier options under model uncertainty. This investigation enriches the literature on the model‐free valuation of these exotic options. It is found that with weak assumptions on underlying price processes, tight valuation bounds on barrier options can be sought from a set of European options. As a result, the numerical routine developed in this article can be reviewed as a new method for the evaluation of barrier options, which is independent of model assumptions. © 2012 Wiley Periodicals, Inc.

Liu,Peter Yi-Chih. The Development of the Advertising Industry in Japan and Taiwan: A Comparison, 1945–1975. Taipei: International Advertising Agency,Ltd., 1975

Abstract

An increase in regulatory activity regarding false and deceptive advertising during the late 1960s and throughout the 1970s instigated an increase in the number of articles on the subject in both the academic and trade journals. Most of the developing literature centered on post hoc regulation done by formal government agencies (such as the FTC) and informal self-regulatory agencies (such as NAD/NARB). Largely overlooked was the routine but important advertising clearance process that addresses matters of falseness, deception and taste before the advertisements appear in the media. Recent trends toward de-regulation make the clearance process more important than ever before.

This article focuses on widely followed clearance procedures prevalent among major advertisers who use agencies and national media. A case example is included to show nuances and intricacies of the process. Common exceptions to the example are noted. Figures are included to model the general process and primary concerns of the involved parties.     

Routine contraction in good times: An example of a typical prototype development routine

The general wisdom in the routine literature is that routine contraction happens as a response to adverse situation. This study examines routine contraction even during non-adverse situations. Here, routine contraction is operationalized as the shrinkage of resources. The data is hand collected from the public website of the National SCRABBLE^® Championship, 2010. Here, each SCRABBLE^® routine is an analogy of a prototype development routine. The higher order relationships between SCRABBLE^® routines and prototype development routines in a second generation Stage Gate^® product development process are mapped following structure mapping theory. The results of panel regressions indicate that the performance of a routine at a particular time (t₀) positively affects contraction of the same routine at an immediately later time (t₁). Efficiency moderates this relationship. Routine contraction may happen even in good times. The paper closes with theoretical contribution and managerial implications of these results.     

Accounting for the employment effects of changes in trade

Simple “accounting” methods have been used to estimate the effects of changes in trade on sectoral employment. Using an applied general equilibrium (AGE) model with Canadian data for 1972 and 1980, this article examines an accounting method first employed in a Brookings study by Charles Frank. The results suggest that despite the criticism it has received, this method provides a reasonable way of assessing the change in employment attributable to changes in imports.

Customer-Perceived Value in Long-Term Buyer–Supplier Relationships: The General B2B Insurance Sector

This article explores the role of customer-perceived value in long-term buyer–supplier relationships. This article aims to identify what creates value for organizational customers, particularly in the field of professional business-to-business (B2B) general insurance services. On the integrated grounds of customer relationship theory in marketing and the resource-based view in strategic management, qualitative research, coupled with interviews, was conducted to explore insights from various representatives of different Vietnamese general insurance firms. The findings suggest that reliability, risk coverage, reputation, technology, interpersonal skills, and technical skills are the six most important types of resources that insurance companies should possess to enhance customer-perceived value.
