Recently, innovation‐oriented firms have been competing along dimensions other than price, lead time being one such dimension. Increasingly, customers are favoring lead time guarantees as a means to hedge supply chain risks. For a make‐to‐order environment, we explicitly model the impact of a lead time guarantee on customer demands and production planning. We study how a firm can integrate demand and production decisions to optimize expected profits by quoting a uniform guaranteed maximum lead time to all customers. Our analysis highlights the increasing importance of lead time for customers, as well as the tradeoffs in achieving a proper balance between revenue and cost drivers associated with lead‐time guarantees. We show that the optimal lead time has a closed‐form solution with a newsvendor‐like structure. We prove comparative statics results for the change in optimal lead time with changes in capacity and cost parameters and illustrate the insights using numerical experimentation. 相似文献

This article argues that a better management of increasingly complex socio-ecological systems would require to adopt evidence-based policy-making and improve the science–policy interface by means of participatory action research involving scientists, citizens and policy-makers. The connectivity between the production of scientific evidence by experts and the delivery of policies by policy-makers is currently unsatisfactory. There is the need to find more effective knowledge mechanisms between researchers and policy-makers. A new way of connecting scientists and policy-makers is to invite a “third player” to the game, i.e. the citizens and stakeholders who are interested in or affected by policy decisions, to perform pilot experiments of participatory research. Participatory research combines different forms of knowledge. “Objective” knowledge produced by scientific disciplines is needed to describe, explain or understand a phenomenon, but participatory research brings in the contribution of citizens' everyday knowledge, e.g. their intimate familiarity with their environment and social context. The approach is illustrated with the aid of examples provided by a number of EU-funded participatory research projects coordinated by ISIS: RAISE (www.raise-eu.org), MOVE TOGETHER (www.move-together.net) and AWARE (www.aware-eu.net). 相似文献

Decentralized decision making is a fact in the modern business world accompanied by extensive research that looks into its consequences for overall firm profits. We study the interactions of decentralized marketing and operations divisions in a corporation and explore their impact on overall firm profits in the case with and without coordination of the two decentralized units. We assume that the marketing department is responsible for the price that influences the demand (sales), and the operations department is responsible for the production rate. We allow for backlogging over time. We model the interdependence involving marketing and operations decisions as a non‐cooperative differential game, with the two divisions as strategically interacting players. We find that, without coordination, strategic interactions of marketing and production result in inefficiencies that can quantitatively be substantial. Next, we introduce a dynamic transfer pricing scheme as a coordination device and evaluate if it establishes efficient (first best and fully coordinated) outcomes. We show that if production and marketing play a game with pre‐commitment strategies, there exists a dynamic transfer price that efficiently (fully) coordinates decentralized decision making and hence results in Pareto‐efficient company profits. If the two decentralized divisions play a game without pre‐commitment, dynamic transfer prices can partially coordinate decentralized decision making but fail to fully eliminate overall inefficiencies arising from strategic interactions among decentralized divisions. 相似文献

组织间界面规则的演进是组织理论研究的一个重要问题。网络环境下组织间界面规则的演进就是团队的管理边界与社会心理边界通过漂移与重合运动所达到的一种相互平衡的关系结果,团队间界面规则的演进是一种内生性改变,是一个自组织的动态演进过程,团队间界面规则演进的“双元模式”和团队学习是推动组织界面规则动态演进的内在机理。 相似文献

根据自发脑电的特点,将HMM-AR模型算法运用到脑电状态的分类中,证明它是一种非常有用的分析脑-机接口方法。将Laplacian filter、ICA和HMM-AR方法相结合,用想象左右手运动的BCI数据进行识别,得到了很好的分类结果,有效地区分脑电中运动与非运动两种状态。该算法能够在运动开始后1 s内检验到脑电信号的变化,从而证明了该算法在BCI的实用性,达到了良好的识别效果。 相似文献
