Tactical coordination in a multi-location and multi-stage operations structure: A model and a pharmaceutical company case

In this paper, we look at the internal supply chain of an internationally operating firm characterized by a multi-location and multi-stage operations structure. We address problems at three levels, namely the strategic, tactical, and operational levels. Our approach goes beyond the operational literature, and focuses primarily on the tactical level. We specify a model and a case that capture strategic and tactical issues and relate the tactical issues to organizational issues. We simulate coordination in different organizational forms pertaining to the ‘tactical control’ of the firm. Our analysis suggests that a functionally organized multi-location and multi-stage operations structure using traditional planning will not work. The choice is between a strongly IT-based, centralized organization or a more decentralized organization using transfer prices as the coordination device.     

Unlocking the Value of RFID

RFID (Radio‐Frequency Identification) technology has shown itself to be a promising technology to track movements of goods in a supply chain. As such, it can give unprecedented visibility to the supply chain. Such visibility can save labor cost, improve supply chain coordination, reduce inventory and increase product availability. Industry reports and white papers are now filled with estimates and proclamations of the benefits and quantified values of RFID. Early adopters are now rallying more and more followers. However, most such claims are educated guesses at best and are not substantiated, that is, they are not based on detailed, model‐based analysis. This paper argues that there is a huge credibility gap of the value of RFID, and that a void exists in showing how the proclaimed values are arrived at, and how those values can be realized. The paper shows that this credibility gap must be filled with solid model analysis, and therefore presents a great opportunity for the Production and Operations Management (POM) research community. The paper reviews some of the ongoing research efforts that attempt to close the credibility gap, and suggests additional directions for further strengthening the POM's contribution to help industry realize the full potentials of RFID.     

多分销中心供应链模型及其牛鞭效应的H∞控制

本文在文^[1]具有一个分销中心供应链模型的基础上,建立了具有多个分销中心的供应链结构模型,采用供应链上游库存与订货偏差波动之和与下游顾客需求偏差波动之比描述牛鞭效应。提出顾客末端需求波动最差条件下H_∞控制方法,以抑制牛鞭效应。这一方法本质就是供应链末端需求波动最差情况下,制定供应链管理的最优决策。并且以一个石油分销系统为对象进行了供应链牛鞭效应的H_∞控制仿真实验。     

一类供应链的线性转移支付激励机制研究

针对不同的供应链设计不同的契约是供应链协作的一个重要手段。在由一个零售商和一个供应商组成的供应链中,零售商的促销努力水平对供应链的效率有重大的影响,本文提出了一种线性转移支付激励机制,且证明了在该机制的作用下,零售商将付出对整个供应链最优的促销努力水平,这时供应链的总收益将得到提高,而对新增收益的划分则取决于供应商和零售商之间的讨价还价能力。     

Scrutinising the interplay between governance and resilience in supply chain management: A systems thinking framework

Supply chain disruptions recurrently challenge end-to-end operations owing to the ambiguous understanding of the role of governance in impacting supply network resilience. This paper scrutinises the relevant literature to understand the plethora of interpretations in supply chain governance and resilience while further providing a new perspective on the representation of the interplay between governance and resilience in supply chains. In this regard, the Systems Thinking lens is adopted to pull together the typologies and constructs of supply chain governance and resilience from the literature. Methodologically, System Dynamics modelling principles are leveraged to capture the underpinning structural interdependencies in a causal loop diagram. The study reveals that endogenous and exogenous supply chain governance processes and mechanisms support the intrinsic and extrinsic resilience in networks. Overall, this research contributes to the supply chain risk management domain by synthesising the interplay between governance and resilience, identifying pertinent typologies, and articulating research propositions that can inform decision-making at policy and management levels.     

考虑学习效应的可复用物流容器供应链的最优运作决策研究

本文研究了单个制造商通过可复用物流容器将产品送至单个零售商的闭环供应链,在可复用物流容器回收处理后得到的数量小于发出时数量的条件下,本文考虑可以通过工人操作过程中存在的学习效应来降低可复用物流容器的丢弃率。本文构建了两个模型：模型1未考虑维修中心工人操作过程中存在的学习效应,可复用容器的丢弃率为随机变量;模型2考虑维修中心工人在操作过程中存在学习效应,使得可复用物流容器的丢弃率不断降低。通过定量分析确定了最小联合库存总成本下的最优运行周期、货物配送次数以及可复用容器配送次数。结果表明,在任一供应链参与者不采取降本措施的情况下,仅考虑工人在操作过程中存在的学习效应就可以起到降低容器丢弃率、节约总成本的效果。此外,本文还分析了制造商可以支付给工人的最大维修费用,为企业的成本投入预算提供决策依据。     

基于制造商O2O模式选择的O2O供应链定价与网上交货期决策

以制造商主导的O2O供应链为背景,考虑市场需求受价格和网上交货期的影响,针对网上直销和网上代销两种O2O模式分别构建O2O供应链定价与网上交货期决策模型,研究渠道成员的最优策略并分析其性质。再通过数值算例分析了价格敏感型消费者情境和网上交货期敏感型消费者情境下消费者网上销售渠道偏好程度和佣金率对O2O供应链最优策略和利润的影响,并探讨了制造商O2O模式的选择问题。发现：消费者网上销售渠道偏好程度越高,越有利于制造商和O2O平台,但不利于线下门店;佣金率越高,越有利于线下门店和O2O平台,却不利于制造商。当消费者更关注网上交货期时,缩短网上交货期并不利于制造商;而当消费者更关注价格时,延长网上交货期是有利的。制造商的O2O模式选择主要受佣金率的影响,只有当佣金率处于较低范围时网上代销O2O模式是制造商的较优选择。
