Information sharing in supply chains: Incentives for information distortion

The existing literature on supply chain information sharing assumes that information is shared truthfully. Unless each party can verify the authenticity of the other party's information, manufacturers and retailers may divulge false information for their own benefit. These information distortions may reduce the benefit levels or even stop information sharing in supply chains. We analyze the incentives for manufacturers and retailers within a supply chain to distort information when they share it and propose a mechanism that results in truthful information sharing. We consider a make-to-order supply chain consisting of a single manufacturer and a single retailer. The manufacturer and the retailer set prices based on their private forecasts of uncertain demand. If both parties share their forecasts truthfully, the manufacturer always benefits; however, the retailer benefits only if the manufacturer sets a lower wholesale price when information is shared compared to when information is not shared. However, we show that the manufacturer and the retailer, respectively, have an incentive to overstate and understate their forecasts while sharing information. The information distortion phenomenon is the direct result of each party exploiting its private information to appropriate the gains from information sharing. We show that the incentives to distort information are eliminated and both parties benefit from information sharing if the manufacturer and the retailer can agree on their relative profit margins prior to information sharing.

Effects of managerial ties and trust on supply chain information sharing and supplier opportunism

Managerial ties and trust are important factors in facilitating collaboration and reducing opportunistic behaviour. There is, however, a lack of empirical evidence on how these relational factors influence the sharing of information among supply chain partners. For example, do stronger managerial ties help to improve supply chain information sharing (SCIS) and reduce supplier opportunism? To what extent SCIS is influenced by managerial ties and trust? How do managerial ties interact with trust in influencing SCIS? Using data from 272 Chinese manufacturers, this paper examines the impact of managerial ties and trust on SCIS and supplier opportunism. The results show that, through trust managerial ties can significantly influence the extent of information sharing and the quality of the information shared. Managerial ties also have a direct impact on the extent of information sharing, but not on the quality of the information shared. The main implication for management practice is that the quality of the information shared – rather than the extent of information sharing – should be seen as the main leverage in reducing supplier opportunism.     

Towards Privacy-Preserving Cloud Storage: A Blockchain Approach

With the rapid development of cloud computing technology, cloud services have now become a new business model for information services. The cloud server provides the IT resources required by customers in a self-service manner through the network, realizing business expansion and rapid innovation. However, due to the insufficient protection of data privacy, the problem of data privacy leakage in cloud storage is threatening cloud computing. To address the problem, we propose BC-PECK, a data protection scheme based on blockchain and public key searchable encryption. Firstly, all the data is protected by the encryption algorithm. The privacy data is encrypted and stored in a cloud server, while the ciphertext index is established by a public key searchable encryption scheme and stored on the blockchain. Secondly, based on the characteristics of trusted execution of smart contract technology, a control mechanism for data accessing and sharing is given. Data transaction is automatically recorded on the blockchain, which is fairer under the premise of ensuring the privacy and security of the data sharing process. Finally, we analyzed the security and fairness of the current scheme. Through the comparison with similar schemes, we have shown the advantages of the proposed scheme.

Characteristics affecting management of design information in the production system design process

Although it has been argued that the design of production systems is crucial, there is a general lack of empirical studies analysing and identifying resources and capabilities required for an efficient production system design process. One of these resources is the critical role attributed to design information and one such capability is how the design information is managed. To address this research gap, this paper reports the results from two in-depth case studies in the automotive industry focusing on the management of design information in the production system design process. Our results show that design information management needs to be understood as a multidimensional concept having three dimensions: acquiring, sharing and using design information. By focusing on the three dimensions, six characteristics affecting the management of design information when designing the production system are identified. The characteristics are information type, source of information, communication medium, formalisation, information quality and pragmatic information.     

Impact of reputation information sharing in an auction-based job allocation model for small and medium-sized enterprises

This research investigates the impact of reputation information sharing in an auction-based job allocation system using a multi-agent based simulation model based on three performance measures: economic efficiency, throughput index, and penalty index. Two forms of reputation information sharing systems, dyadic and public, were implemented and studied. Dyadic reputation systems deal with one-to-one information sharing, while public reputation systems deal with many-to-many information sharing. The paper proposes a hybrid auction mechanism, which is a combination of the sealed bid and reverse auction mechanisms. Analysis of the simulation results shows that reputation information sharing benefits the system tremendously by increasing the overall economic efficiency and throughput index, while decreasing the penalty index of the system. The results also show that as the significance of reputation in the market increases, the benefits realised in terms of economic efficiency and throughput index also increases.     

Determination of the optimal degree of information sharing in a two-echelon supply chain

Information sharing is beneficial for supply chains, but often has marginally decreasing impacts on profit due to the costly expense of collecting more detailed information. This study aims to determine the optimal degree of information sharing with consideration of the trade-off between the cost of collecting information and the benefits gained by utilising it to enhance the profit of a two-echelon supply chain. Based on the analytical results, the profit that the supplier gains from information sharing can stem from the decrease in inventory cost after having more accurate information about demand. Furthermore, the impacts that the cost of collecting information has on the optimal degree of information sharing are investigated, and the results show that the optimal degree of information sharing is positively correlated to the correlation of successive market demand, that is, when the demand for successive periods is more correlated, information sharing becomes more valuable, and hence the optimal degree of information sharing increases.

Ex post demand information sharing between differentiated suppliers and a common retailer

We consider ex post demand information sharing in a two-echelon supply chain in which two suppliers sell differentiated products through a common retailer. We model three scenarios of information sharing to characterise the conditions under which information sharing may benefit or hurt different players: (1) no supplier is informed; (2) only one supplier is informed; and (3) both suppliers are informed. We find that the retailer may voluntarily share the low demand information when the product differentiation and demand magnitude satisfy certain conditions. In contrast, the retailer has no incentive to share the high demand information, even though this information benefits the suppliers. To achieve information sharing, we propose a side payment mechanism, which allows benefitted players to subsidise hurtful players. Finally, we extend our model by considering a situation where the suppliers have limited capacity and may invest to ramp up production capacity to satisfy a high demand.
