基于排队论的超市收费服务模型的探讨

提高顾客的通过速度,减少顾客收费的停留时间是提高超市的服务质量有效途径之一。排除论作为研究服务系统中排除现象随机规律的学科,如能将其运用于超市服务系统的规划当中,有重要的实践意义。文章根据排除论的思想建立了超市的排队服务模型。通过对模型的优化设计,科学地确定超市服务收费通道数量,并通过实例说明了该方法的计算过程,证明排队论在超市服务系统优化中具有实际用途,为类似的设计提供参考。     

Assessing supply chain risks with the analytic hierarchy process: Providing decision support for the offshoring decision by a US manufacturing company

This paper reports the process used by a US manufacturing company to assess supply chain risks within the context of an offshore sourcing decision. The case study company was faced with the objective of finding a new supplier for two of its major product lines. Five alternatives were considered: (1) sourcing finished goods from Mexico; (2) sourcing finished goods from China; (3) sourcing parts from China and assembly in the US; (4) sourcing parts from China, assembly in a Maquiladora in Mexico with investment; and (5) sourcing parts from China, assembly in a Maquiladora in Mexico with no investment in the venture. To find the best solution, action research methodology was combined with the application of the analytic hierarchy process (AHP). Through iterative and structured discussions, 17 risk factors were identified, which were subsequently grouped into main and sub objectives. AHP was then used to evaluate the importance of each risk factor, and to determine the best alternative. This study makes several contributions to the field of purchasing and supply management. First, it provides a comprehensive framework of empirically derived risk factors to be considered in an international sourcing context. Second, it shows how AHP can be used to assess these risk factors and alternatives as part of the framework to facilitate and support the final offshoring decision. And third, it illustrates the successful application of the approach by a US manufacturing company. As such, this paper contributes to the research streams of offshoring and risk management in purchasing and supply, as well as to decision-making under uncertainty and AHP. In addition, it serves as a practical methodology for firms in similar situations.

The Rocky Road to Legacy: Lessons from the 2010 FIFA World Cup South Africa Stadium Program

This article describes how the management and organization of the South African 2010 FIFA World Cup stadium program shaped the current legacy of an oversupply of overdesigned and underutilized stadiums. The article identifies seven key factors that explain the differences between expected benefits and the actual legacy. Identification of these factors contributes to the increasing academic interest in explaining the poor legacy outcomes of mega‐events. In conclusion, we recommend that future host country governments defragment their stadium programs by establishing a World Cup Delivery Authority (WCDA), with responsibility for the leadership and coordination of the stadium program.     

Educational Development in South Sudan: Conscious Design or Spontaneous Order?

Educational development is key to the future prosperity of South Sudan. Officially the situation appears bleak with up to 50 per cent of primary‐aged children out of school, high reported dropout rates and poor attainment. Those involved in the development of education, government departments, international agencies, individuals and communities are each following one of two different approaches as they seek to extend the reach of education. The article suggests that these different approaches arise because those involved hold to either a conscious‐design or a spontaneous‐order model for educational development. The article looks at the recent development of schools in Juba, the capital of South Sudan, in the light of these two theories and finds, despite the rhetoric of the official reports, that most growth is organic and that most recent educational development is emerging spontaneously.     

On axiomatizations of the Shapley value for assignment games

We consider the problem of axiomatizing the Shapley value on the class of assignment games. It turns out that several axiomatizations of the Shapley value on the class of all TU-games do not characterize this solution on the class of assignment games. However, when considering an assignment game as a (communication) graph game where the game is simply the assignment game and the graph is a corresponding bipartite graph where buyers (sellers) are connected with sellers (buyers) only, we show that Myerson’s component efficiency and fairness axioms do characterize the Shapley value on the class of assignment games. Moreover, these two axioms have a natural interpretation for assignment games. Component efficiency yields submarket efficiency stating that the sum of the payoffs of all players in a submarket equals the worth of that submarket, where a submarket is a set of buyers and sellers such that all buyers in this set have zero valuation for the goods offered by the sellers outside the set, and all buyers outside the set have zero valuations for the goods offered by sellers inside the set. Fairness of the graph game solution boils down to valuation fairness stating that only changing the valuation of one particular buyer for the good offered by a particular seller changes the payoffs of this buyer and seller by the same amount.     

Intra- and interorganisational learning processes: an empirical comparison

The organisational learning literature has so far focused primarily on intraorganisational learning processes. However, during the last 10 years or so, a growing number of organisational learning studies have focused explicitly on interorganisational learning. So far this literature has concentrated on the requirements for such learning. Little attention has been devoted to examining the potentially unique dynamics of interorganisational learning processes. Consequently, few if any studies have examined whether interorganisational learning processes differ from traditional intraorganisational learning and, if so, in what respects. The purpose of this paper is to make an empirical comparison between intra- and interorganisational learning processes by drawing on a longitudinal qualitative case study of experiential learning processes within and between a business organisation and its partners, continued over a period of 3 years.

What you see is meaningful: Does green advertising change the intentions of consumers to purchase eco-labeled products?

Consumers are increasingly worried that their current consumption patterns have negative environmental impacts, which in turn shapes their green purchase intentions. Based on the signaling theory and stimulus–organism–response model, the purpose of this research is to construct a theoretical framework to understand consumer intentions to buy eco-labeled products. Empirical results from 671 questionnaires show that as expected, green advertising receptivity positively affects intention, and the relationship between green advertising receptivity and intention is also moderated by promotion focus and mediated by system trust and personal trust. However, the relationship between green advertising receptivity and purchase intention is not moderated by prevention focus. Hence, this research suggests that stakeholders should conduct truthful green advertising campaigns to dispel consumer suspicion and target different consumers with different green advertising and marketing campaigns to increase sales.
