Impact of demand correlation and information sharing in a capacity constrained supply chain with multiple-retailers

This paper considers a single product, two-echelon capacity constrained supply chain consisting of a supplier and two retailers facing correlated end-item demand. We use a decentralized Markov decision process with restricted observations to represent this system and conduct a numerical study to quantify the benefits of information sharing to the retailers under varying levels of supplier capacity and supply allocation mechanisms. Our results show an inverse relationship between capacity and information and indicate the retailers can achieve significant benefits as a result of the information sharing partnership.     

采纳区块链技术的两级供应链信息共享博弈

针对中小型供应链成员是否建立基于区块链技术的信息共享平台以及建立后的价值问题,考虑消费者的质量和价格敏感,分析了由零售商主导并包含两个地位不等的制造商的供应链中基于区块链技术的信息共享问题.本文分别构建传统合作模型、基于区块链技术的信息共享短期模型和长期模型,探讨不同模式下的供应链价值和模式选择.结果表明:短期而言,建立基于区块链技术的信息共享平台会扩大制造商之间的地位差距,致使强者愈强而弱者愈弱,零售商的利润会受损.长期而言,信息共享带来的质量努力效应会缩小制造商之间的差距并增加利润,零售商和整个供应链在经历短期的阵痛之后利润会显著增加.可知当消费者对价格和质量敏感性较高时,建立基于区块链技术的信息共享平台对实力较强的制造商是有利的,对实力较弱的制造商是不利的,对供应链是长期有利的,否则,不建立基于区块链技术的信息共享平台对供应链和实力较弱的制造商是有利的.     

The value of information sharing in a supply chain with a seasonal demand process

This paper considers a two echelon seasonal supply chain model that consists of one supplier and one retailer, with the assumption that external demand from the customer follows a seasonal autoregressive moving average (SARMA) process, including marketing actions that cannot be deduced from the other parameters of the demand process. In our model, the supplier and the retailer employ order-up-to policy to replenish their inventory. In order to evaluate the value of information sharing in a two echelon seasonal supply chain, three levels of information sharing proposed by Yu, Yan, and Cheng (2002) are used. The results for optimal inventory policies under these three levels of information sharing are derived. We show that the seasonal effect has an important impact on optimal inventory policies of the supplier under the three levels of information sharing. Our findings also demonstrate that the replenishment of lead time must be less than the seasonal period in order to benefit from information sharing. Thus, this result provides managers with managerial insights to improve supply chain performance through information sharing integration partnerships.     

The antecedent factors on trust and commitment in supply chain relationships

The primary purpose of this study is to investigate the role of information sharing, information quality, and information availability in the development of trust and commitment in supply chain relationships. Samples were gathered in Taiwan and Canada using a field questionnaire. Multiple regression and ANOVA were used to analyze the data. It was found that there is a positive relationship between the level of quality, and availability, and the level of trust; information sharing and commitment. Additionally, results revealed that country moderates the relationship between information sharing and trust.     

Determination and exchange of supply information for co-operation in complex production networks

Today's manufacturing industry is characterised by strong interdependencies between companies operating in globally distributed production networks. The operation of such value-added chains has been enabled by recent developments in information and communication technologies (ICT) and computer networking. To gain competitive advantages and efficiency improvements such as reduced inventory and higher delivery reliability, companies are introducing information exchange systems that communicate demand to suppliers and production progress information to customers in the network. This article proposes a system that supports co-operation in complex production networks by enabling companies to determine and exchange supply information with their customers. The requirements for such a system are analysed and it is embedded in a framework of supply chain management business processes. The system facilitates the determination and exchange of meaningful, reliable and up-to-date order status information from the supplier to the customer. Based on comparing the progress of an internal production order with a pre-defined milestone model for each product, the status of the customer order is determined and—in case of lateness—communicated to the customer together with an early warning. To demonstrate the developed supply information concepts and processes, the business process is implemented as a pilot system and evaluated by the user companies participating in the 5th Framework IST project Co-OPERATE.     

The effects of business systems leveraging on supply chain performance: Process innovation and uncertainty as moderators

Rooted in the profit-seeking motives of social exchange theory, this study aims to investigate the factors that facilitate leverages of firm’s business systems and their sharing of information with group members, as well as the impacts of business systems leveraging (BSL) on information sharing and supply chain performance. Simultaneously, the moderating effects of uncertainty and the degree of process innovation on the relationship between BSL and supply chain performance are also estimated. The analytical results indicated that proactive technological orientation, information technology (IT) connectivity, supply chain member pressure, and member relationship quality encourage firms to combine their business systems with those of other business partners. Interestingly, in a situation where there is high demand and an uncertain supply, the impact of BSL on supply chain performance is low, while the moderating effect of process innovation on the relationship between BSL and supply chain performance is significant. Finally, it is suggested that firms implementing BSL work to upgrade their technology maintain tight relationships with supply chain partners and create innovation in all aspects of their business processes in order to survive in the highly competitive IT environment.     

System for supply network management

Strategies and algorithms for operational planning and control are quite important to successful operations of a supply network. Implementation of a strategy requires substantial information system support, but few detailed designs of such systems have appeared in the literature. We designed an information system for a centralized management concept that could handle any type of strategy or algorithm. We developed algorithms for two different strategies deemed important by researchers and practitioners, push and pull, and implemented them in system modules. This information system performed well in simulations of the management of operations of an example six-stage supply network. This system provides an example for operational development as well as a platform for laboratory experiments.

Information technology, operational, and management competencies for supply chain agility: Findings from case studies

Given the growing emphasis on the need for supply chain agility to sustain competitive advantage, this study explores the impact of the relationship between supply chain competence and supply chain agility on firm performance. Although the influence of supply chain agility on firm performance has been acknowledged, this study further articulates the relationship from the perspective of inter-organizational collaboration. We develop a conceptual model based on the resource-based view and employ a multi-case study method in this exploratory research. Our findings highlight the importance of distinguishing the difference between supply chain agility and supply chain competence and their impact on firm performance. This study contributes to the growing body of conceptual and empirical literature on supply chain agility and adds to the understanding of the complexity of supply chain competence.
