在简要介绍了“啤酒游戏”、系统动力学及其仿真软件Vensim的基础上,进一步构建了啤酒游戏的因果关系图和系统动力学流图,并在此基础上应用Vensim/DYNAMO构建了“啤酒游戏”的计算机模型,对其进行了仿真。研究了订货延迟时间对物流库存系统情况造成的影响,比较了两种不同的采购策略对“啤酒游戏”的影响,发现订货延迟时间的存在是造成“啤酒游戏”中“牛鞭效应”的内因,商家过分在意当前的库存与缺货情况,急于补存或者降低库存,反而会造成“牛鞭效应”的加剧。结果表明,如果商家适当的延长库存的补货时间,“啤酒游戏”中的“牛鞭效应”会有所改观,这是现代供应链上的物流企业应该借鉴的。  相似文献

This study investigates the impact of individual risk aversion on replenishment decisions in a multi-echelon supply chain, and explores whether this impact is affected by experiential learning. The methodology applied is that of observational studies, while the multi-echelon supply chain is modeled through the classical Beer Game. Participants in the study are purchasing and supply chain professionals. Results suggest that risk aversion leads to higher orders, Risk aversion persists even after experience of the game has been gained.  相似文献

This paper investigates the impact of capacity constraints and safety stock on the backlog bullwhip effect in a model of a two-tier supply chain. One of the most commonly applied methodologies to study the various aspects of the Beer Game model is the control theoretic technique. It is clear that these control theoretic models are linear and cannot deal with non-linearities, such as capacity constraints. Thereafter, simulation experiments together with Taguchi design of experiments are performed to study non-linear impacts of capacity constraints in a two-tier supply chain. This research gives supply chain operations’ managers and designers a practical way to develop a trade-off between capacity and safety stock at different echelons and to take better decisions about their capacity and safety stocks. Future work should investigate the total cost implications of capacity constraints and safety stocks in a multi-echelon supply chain.  相似文献

Using Ajzen’s theory of planned behavior and Shapero’s entrepreneurial event model as well as entrepreneurial cognition theory, we attempt to identify the relationship between entrepreneurship education, prior entrepreneurial exposure, perceived desirability and feasibility, and entrepreneurial intentions (EI) for university students. The data were collected from a survey of ten universities; we received 494 effective responses. We used probit estimation to show that perceived desirability significantly impacts EI whereas there is no significant impact from perceived feasibility. There is a significant negative impact from exposure (which is surprising) and a significant positive impact from entrepreneurship education. Males and people from technological universities and/or backgrounds have higher EI than females and people from other universities and backgrounds. There are also significant positive interactive effects by gender, university type, and study major on the relationship between entrepreneurship education and EI.  相似文献

This paper adds to the empirical inventory management literature by examining the moderating effects of environmental dynamism on the relationship between inventory leanness and financial performance. While the financial implications of inventory management practices have been extensively studied in the literature, it is clear that lean inventory strategies may not have the same payoff for all firms in all industries. Grounded in inventory theory, this study explores how firm characteristics and environmental dynamism—measured in terms of innovative intensity, demand uncertainty and competitive intensity—moderate the inventory leanness–performance link. We use hierarchical linear modeling to analyze a data set of 5749 firm-year observations from 123 U.S. manufacturing industries. In line with the hypotheses set forth, the results indicate that innovative intensity in an industry increases the effect of inventory leanness on firm performance while competitive intensity has the opposite effect. The hypothesis with respect to the moderating role of demand uncertainty is not supported. Another interesting and important finding is that inventory leanness accounts for nearly one third of the variation in firm performance after controlling for firm size and growth, thus underlining the importance of efficient and effective inventory management for overall firm success.  相似文献

Despite the calls for a deeper understanding of SCM in the healthcare industry, theoretical research focused on healthcare buyer-supplier collaboration, specifically inventory management issues, remains nascent and fragmented. Although slow to change, healthcare organizations have begun to consider alternative inventory management systems to improve inventory control and patient care. Industrial vending machines (IVM) can help healthcare organizations address inventory management issues. Grounded in transaction cost economics and contingency theory, this research develops and empirically tests a model that highlights the critical role of information management in the link between buyer-supplier relationship quality and performance outcomes within the context of IVM implementation and use in the healthcare industry. Based on survey data from healthcare managers, results indicate that both information management and relationship quality are tied to a series of benefits in the context of collaborative buyer-supplier IVM agreements.  相似文献

Surprisingly, deterministic time series can generate highly irregular, random-appearing trajectories. These deterministic time series result from nonlinear dynamical systems of differential or difference equations. The random appearance displayed by these systems is called nonlinear dynamical complexity. Properties of nonlinear complex systems include aperiodic random appearance, sensitive dependence on initial conditions and model parameters, and nonstationarity. Experiments involving the operation of simulated business environments and theoretical nonlinear dynamical models for inventory are reviewed to explore motivating factors that can give rise to demand with nonlinear complexities. The experimental and theoretical evidence reviewed indicates that nonlinear complexities in demand have significant implications for inventory management. Thus, researchers and practitioners in inventory management need to consider these properties when choosing inventory management methods. Characteristics of nonlinear dynamical systems and their implications for inventory management are presented in this paper. The use of the Brock, Dechert, and Scheinkman (1987) (BDS) test for nonlinear dependence is demonstrated on actual demand data.  相似文献

Estimation of the linear quadratic model, the workhorse of the inventory literature, traditionally takes inventories and sales to be first‐difference stationary series, and the ratio of the two variables to be stationary. However, these assumptions do not always match the properties of the data for the last two decades in the United States. We propose a model that allows for the non‐stationary characteristics of the data, using polynomial cointegration. We show that the closed‐form solution has other recent models as special cases. The resulting model performs well on aggregate and disaggregated data. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

囚徒困境及其破解策略在日常工作中的应用举例   总被引:1,自引:0,他引:1  
博弈论就是研究互动决策的理论,主要感兴趣的是其胜负主要取决于谋略智能的对抗性局势,而囚徒困境则博弈论中的经典模型之一。该模型深刻揭示了个人理性与集体理性的冲突。在囚徒困境中,每个人都会根据自己的利益做出决策,但是最后的结果却是集体遭殃。文章以博弈论中的经典模型"囚徒困境"为工具分析解剖日常生活工作中的若干热点和难点问题,并提出相应的破解策略。  相似文献
