Investigating the value of information sharing in multi-echelon supply chains

Under the structure of multiple business entities, supply chain management (SCM) offers the external and internal integration of business processes in enterprises. The most important objective of SCM is to enhance the supply chain performance such as reinforcing the service level and increasing profit as well as reducing order cycle time and inventory. In recent years, due to the advancement of information technology, enterprises can manage the product flow and the information flow via economical and efficient mechanisms. The well-organized information sharing can enhance the supply chain performance and allow enterprises to refine their strategies of supply chain in order to maximize their profits. The previous studies pointed out the positive effect of information sharing on the efficiency of supply chain. However, relatively little literature focuses on the performance analysis for multi-echelon supply chain with various information sharing scenarios. By using the simulation technique, this paper models different scenarios of information sharing, and further analyzes the impacts of information quality on multi-echelon supply chain performance. In addition, this paper employs Data Envelopment Analysis (DEA) to integrate multiple performance measures to ensure the information sharing scenarios with enhanced performance.     

Economic impact of enhanced forest inventory information and merchandizing yards in the forest product industry supply chain

Forest products industry should maximize the value of timber harvested and associated products in order to be competitive in global markets. Enhanced forest inventories and merchandizing yards can help in maximizing value recovery in the forest products supply chain. This study develops an optimization model to analyze the economic impact of enhanced forest inventory information and merchandizing yard operations in the forest products supply chain. The application of the model is demonstrated by using a case study of a hypothetical forest industry in northwestern Ontario, which obtains four log assortment grades from the surrounding eight forest management units. The model analyzes five different scenarios with 0%, 25%, 50%, 75%, and 100% certainty of tree quality in forest inventory information. The results of the study show that with full certainty of tree quality information, it is possible to gain 49% in gross profit in comparison with a scenario with no certainty. The usefulness of enhanced forest inventory and merchandizing yard in the entire supply chain of forest products industry is recognized by maximizing total value of wood fiber (by allocating right log to the right product), reducing fluctuations in raw wood fiber supply, and minimizing inventory carrying costs and lost sales.     

The impact of vertical integration on inventory turnover and operating performance

This paper investigates how vertical integration may influence inventory turnover and firm operating performance. A causal model is developed to investigate the effects of vertical integration on three types of inventory, namely raw materials inventory (RMI), work in progress inventory (WIPI) and finished goods inventory (FGI). The model tests the interactions between inventory types and the consequences of inventory turnover performance on various aspects of firm performance including costs and profitability. In particular, path analysis supports systematic differences with respect to how vertical integration affects RMI, WIPI and FGI. Vertical integration has a positive effect on RMI and FGI turnover but no significant effect on WIPI turnover. FGI contributes to a reduction in supporting processes costs which causes an improvement in return on sales (ROSs). Vertical integration impacts ROS directly.     

Vendor managed inventory: a survey of the Taiwanese grocery industry

Recent research has shown the importance of improving the supply chain competitiveness by means of strategic alliances. This study considers the retailer–supplier partnership through a vendor managed inventory (VMI) system. The characteristics of a VMI system and a retailer–supplier power relationship are discussed in some detail with a case illustration to examine the practical implementations of the system in the Taiwanese grocery industry. VMI not only has the ability to reduce costs, but also to improve service levels and create business opportunities for both parties in the supply chain. Thus, it is considered as one of the main systems in a strategic alliance.     

基于供应商管理库存的信息系统设计研究

自从"零库存"的概念被丰田汽车公司提出以后,40多年来各生产企业绞尽脑汁考虑如何通过有效的运作与管理将库存降到最低.现在,供应商管理库存(VMI,Vendor Managed Inventory)的模式逐渐被国内企业接受.供应商管理库存,是在供应链管理理念下要求的产物。它要求供应商对下游企业库存策略、订货策略以及配送策略进行计划和管理。所以,采用合理模式运作VMI就成了当前要解决的问题。

The effect of cross-organizational governance on supply chain resilience: A mediating and moderating model

This study examines the effect of a novel antecedent, namely cross-organizational governance (which can be further divided into contractual and relational governance), on supply chain resilience. Additionally, it explores the mediating and moderating effects of supply chain collaboration and institutional environment, respectively, on the relationship between cross-organizational governance and supply chain resilience. Accordingly, a research model, together with four hypotheses, is constructed based on institutional theory. These are further tested based on data collected from a single-respondent survey of 358 Chinese manufacturing companies. The results reveal that contractual and relational governance have significant positive effects on supply chain resilience; supply chain collaboration plays a partially mediating role and institutional environment plays a moderating role in the effects of contractual and relational governance on supply chain resilience. This study enriches the understanding of the relationships between cross-organizational governance, supply chain collaboration, supply chain resilience, and institutional environment. It also provides a reference for supply chain managers’ decision-making activities.

VMI系统中供应商的成本变化研究

供应商管理库存(VMI)是目前供应链管理中的重要方法之一。一般来说,在独立的单个零售商和单个供应商间导入VMI系统后,零售商在短期和长期内都能获利,而供应商的利润变化则是不确定的。实行VMI后供应商的成本将会发生很大变化,这是供应商进行决策的主要依据。在指出已有文献存在研究缺陷的基础上,文章对实行VMI后供应商的成本变化进行了进一步的研究。     

基于多级线性规划法论连锁企业库存配送的一体化控制

随着经济全球一体化及我国加入WTO,国外连锁企业加快了进入中国市场的步伐,我国连锁企业面临着越来越严峻的挑战和考验。如果想在激烈的市场竞争中继续保持竞争优势,企业就必须在保证更高客户服务水平的基础上进一步降低物流成本。库存和配送是连锁企业物流系统的核心子系统,两者在成本上存在着此消彼长的关系。因此,连锁企业如果能够将库存和配送两方面的成本统一起来,在两者之间寻求一个平衡点进行库存/配送一体化决策,对于降低连锁企业的物流总成本具有非常重要的意义。
