Based on demand uncertainty, the paper studies inventory management decision of two competing supply chains from the perspective of customer service. The paper mainly discusses two different inventory strategies, which are widely used, that is, consignment stock and VMI, and analyzes the optimal policies under three competitive scenarios, which consist of using consignment stock in both supply chains (CC mode), using VMI in both supply chains (DD mode), and using consignment stock in one supply chain but VMI another (VC mode). The paper compares equilibrium inventory level and profit of supply chain in different competitive modes, and concludes that both supply chains use VMI is equilibrium, which means that when manufacturers have right to choose inventory management policy, they prefer VMI. But it isn’t paradoxical with the phenomenon that consignment stock is common in reality, because manufacturers are forced to use consignment by retailer’s channel power.

Customer Service Level

Inventory management remains a key challenge in supply chain management. Many companies recognize the benefits of a good inventory management system. An effective inventory management helps reaching a high customer service level while dealing with demand variability. In a complex supply chain network where inventories are found across the entire system as raw materials or finished products, the need for an integrated approach for managing inventory had become crucial. Modelling the system as a multi-echelon inventory system allows to consider all the factors related to inventory optimization. On the other hand, the high criticality of the pharmaceutical products makes the need for a sophisticated supply chain inventory management essential. The implementation of the multi-echelon inventory management in such supply chains helps keeping the stock of pharmaceutical products available at the different installations. This paper provides an insight into the multi-echelon inventory management problem, especially in the pharmaceutical supply chain. A classification of several multi-echelon inventory systems according to a set of criteria is provided. A synthesis of multiple multi-echelon pharmaceutical supply chain problems is elaborated.

Last Mile Delivery

With traditional ERP systems, there is a lack of networking among suppliers, partners, and logistics providers. So, there is a need to have a holistic view of production and movement of goods from production to last mile delivery. The physical and digital supply chains need to be integrated to ensure secure supply chains that promote business excellence, collaboration among stakeholders, and reduce costs. The high-level view over their supply chains allows them to function better in a multi-channel world. It also helps them identify where to reduce stock without compromising customer service. Otherwise, it leads to a delay in delivery, counterfeit products, thefts, fraud, and cyberpiracy, which may lead to lawsuits and losing of brand image. The tacit function of supply chain management is to provide tracking of specific goods in the supply chain. So, it is imperative to leverage the blockchain technology stack to map multi-enterprise value networks and enable connected multi-modal networks.

Supply Chain Governance

Purpose The purpose of this paper is to investigate how small manufacturing firms develop and manage relationships with global suppliers and distributors. In so doing the authors aim to contribute to knowledge about SMEs and supply chain management (SCM). Design/methodology/approach The authors conducted 12 in-depth case studies of SME final assemblers of machinery in the French farm equipment sector. Findings The most effective form of global supply chain governance used by successful SMEs is informal networks involving managers in similar complementary firms, which serve to concatenate links with foreign suppliers and distributors. Research limitations/implications The principal limitation of this research is that it is specific to one sector and therefore questions of transferability are raised. Practical implications The important implication for managers in manufacturing SMEs is that links with other complementary local firms in the same sector need to be developed, leveraged and valued. Originality/value The originality of this case research is that the authors draw on inter-organisational boundaries, power asymmetries and network governance to develop a conceptual framework for the study of SMEs and global supply chains. By focusing on the perceptions of boundary-spanning managers, the authors show how, in circumstances of demand uncertainty, soft network governance is an effective strategic choice.

Purpose – This paper aims to empirically explore demand-related information sharing in the extended supply chain. Design/methodology/approach – Through a single, embedded case design, a range of methods are used to collect data from companies representing three different supply chain tiers, including focal company, first-tier suppliers and first-tier customers. The collected data are analysed through the theoretical lens of interdependence. Findings – The findings indicate that the supply chain actors adapt information sharing to the pooled, serial or reciprocal type of interdependence. Information sharing is thus increased with key dyadic partners representing, for example, unique offerings and high market shares as percentage of total expenditure/sales. The study also unearths several barriers to information sharing beyond dyadic ties, including problems related to dis-aggregated, misinterpreted and/or incomplete information. Research limitations/implications – The study empirically contributes to the existing literature by exploring information sharing in the extended supply chain and by suggesting different approaches to information sharing depending on the type and intensity of interdependence between supply chain partners. Further, the paper contributes to the existing literature on barriers of information sharing in supply chains by identifying barriers specific to multi-tier information sharing. “Meta-information” (i.e. information about the shared information) is needed to overcome some of the barriers of sharing information in cases of weak, pooled interdependencies in the supply chain. Practical implications – Similar to previous empirical research, this exploratory study indicates that companies, in general, refrain from sharing information beyond dyadic ties. Supply chain managers would instead mostly focus on stronger, reciprocal interdependencies and emphasise dyadic information sharing. To further guide managers, a demand profiling framework considering market share and demand uncertainty is presented. It may be interesting to engage in multi-tier information sharing in particular cases where strong interdependence exists between three or more partners. Originality/value – This study contributes to existing research on information sharing in supply chains by empirically studying information sharing in an extended supply chain, applying interdependence theory as its analytical framework and unearthing several barriers that are specific to multi-tier information sharing.

The Relationship

Purpose – The purpose of this paper is to provide some empirical evidence of the relationship between strategy and structure/processes in supply chains on the basis of the results of an exploratory analysis using survey data from Japanese manufacturers. Design/methodology/approach – This study explores the differences of structure/processes among the four supply chain strategies, that is, efficient, responsive, efficient/responsive, and traditional. Specifically, this study conducts a one-way analysis of variance of the structure/process variables by supply chain strategies. Findings – As the results of exploratory analysis including follow-up interviews with survey respondents, this study found many differences between traditional and efficient/responsive firms on process variables. With regard to structure variables, the existence of a supply chain management department, which is a variable of internal structure, in responsive and efficient/responsive firms is statistically more likely than in efficient firms. In addition, this study found significant differences between efficient and responsive firms, and traditional firms on some variables of external structure. Research limitations/implications – The results of this study explain why efficient/responsive firms can achieve high level of customer service and low operating cost, which is demonstrated by Qi et al. (2009). In addition, this study statistically ensures the validity of Stavrulaki and Davis’s (2010) proposition that firms with agile strategy tend to conduct opportunistic collaboration or have collaborative barriers with their suppliers because of their flexible supply base. Originality/value – This is the first empirical study that explores the relationship among management elements in supply chains including not only strategy but also structure and processes. Through this study, it is implied that the strategy-structure-processes-performance paradigm adopted in this study is useful for exploring the patterns of other management elements that fit in with supply chain strategies.

The present study is an attempt to quantify the Bullwhip Effect (BWE) -the phenomenon in which information on demand is distorted in moving up a supply chain. Assuming that the retailer employs an order-up-to level policy with auto-regressive process (AR), the paper investigates the influence of forecasting methods on bullwhip effect. Determining the order-up-to levels and the orders for the retailers’ demands in an isolated manner neglects the correlation of the demands and the relevant risk pooling effects associated with the network structure of the supply chains are disregarded. It is illustrated that the bullwhip effects are significantly reduced with consideration of potential correlation between the retailers’ demand.

Historically, the echelons of the supply chain, warehouse, distributors, retailers, etc., have been managed independently, buffered by large inventories. Increasing competitive pressures and market globalization are forcing firms to develop supply chains that can quickly respond to customer needs. To remain competitive and decrease inventory, these firms must use multi-echelon inventory management interactively, while reducing operating costs and improving customer service. The current paper reviews the literature, addressing multiechelon inventory management in supply chains from 1996 to 2005. The behaviour of the papers against demand and lead-time uncertainty is the key analysis point of the literature review presented here and it is conducted from an operational research point of view. Finally, directions for future research are suggested.
