C2C电子商务的后向物流模式探讨

c2c卖家在c2c物流价值中具有双重身份:物流选择的代理人和物流活动的委托人,使得卖家拥有选择物流商和分割买家支付的权力,而物流的低效率不会带来卖家收益的降低,从而产生道德风险,以买家价值为导向的后向物流模式可以打破卖家的双重身份.

基于WBS的建设工程监理动态控制研究

建设工程监理是一种以严密制度为特征的综合管理行为,传统的管理模式已不能胜任现代工程的新特点。为了合理地进行计划、组织、协调、控制,监理企业必须结合现代工程项目的管理方法,充分利用现代项目管理软件进行控制。文中引入项目管理的系统方法,采用工作分解结构（WBS）方法,对工程项目进行分解,提出一种监理工作的明确表示法。在此基础上结合P3e／c的项目管理信息系统,实现建设工程监理的动态控制。     

An economic-statistical design of double sampling control chart

The double sampling (DS) chart can reduce the sample size when monitoring the process mean. In this study, Duncan's cost model was modified by adding the statistical constraints to develop the design model of DS chart for the optimization of design parameters—sample size, control limit coefficient, warning limit coefficient and sampling interval. A numerical example was provided to illustrate the use of this model. A sensitivity analysis of the effects of model parameters and statistical constraints on the optimal design of DS chart was also performed.     

Ritual legitimation, de-coupling and the budgetary process: managing organizational hypocrisies in a multinational company

The study of participation in the budgetary cycle has formed a prominent part of the research literature concerned with the budgetary process. More recently there has emerged a body of literature concerned with exploring the political and symbolic nature of the budgetary process. The paper reports upon the outcomes of an empirical study of the introduction of `budgetary participation' in a division of a European subsidiary of a large North American car manufacturer. We detail the long process of consultation and negotiation within the subsidiary, and between it and the European Headquarters. The study provides a revealing instance of the roles of formal budget participation as a ritual of control and legitimation without the substantive involvement of middle managers and suggested to us the introduction of de-coupling and organizational hypocrisy alongside the introduction of budget participation. The study pays close attention to the contingent effects of the wider political context of the division and the relationships between the division, its organizational context and organizational environment, and how this context played upon the budgetary process in the division. The outcomes that we analyse at `Delta' reflect the de-coupling strategies and organizational hypocrisies commonly found in public sector organizations. In this wider setting the corporation persists with the ritual of `tight' budget negotiation and target setting and apparent underachievement in performance. Yet we conclude that the complex technological and political context to the formation and siting of Delta continued and may continue to support its existence.$g0     

Robustness of some non-uniform random variate generators

Often the usefulness of a random variate generator for a distribution is based on the successful generation of independent variates from the uniform distribution. However, no pseudo-random number generator is capable of generating a truly random uniform sequence. As the cost of computations is now dramatically reduced, the computational efficiency should not be the primary criterion in choosing a good generator. Proposed here is a robustness criterion which is designed to study the effect of an imperfect pseudo-random number generator on the accuracy of a random variate generator. In particular, the beta and binomial variate generators are examined for their robustness to the non-uniformity of a pseudo-random number generator.     

The multi-organizational interaction approach to industrial marketing

A conceptual approach is presented for investigating interaction processes in industrial marketing.The interaction process is interpreted as a multi-organizational phenomenon which is characterized by indegenous episode variables and contextual factors. Empirical results using this interaction approach are discussed, and the importance of analyzing the influence of relative organizational attributes (relative to each organization involved in the interaction process) on the results of an industrial marketing transaction is stressed.
