Abstract:Firms are increasingly held accountable for their suppliers' transgressions. Consequently, firms need to develop upstream visibility to exercise control over their supply chains. An emerging body of work has recognized the importance of supply chain visibility and has examined it using analytical models, behavioral methods, and case studies. Still, large-sample empirical evidence on the benefits of supply chain visibility remains elusive. We seek to bridge this gap by examining conflict minerals disclosures (m… Show more
“…Since poor visibility on supply chains has negative effects such as long lead times [42], counterfeiting [16], stock-outs situations [43], bullwhipeffect [44] and high inventory cost. Although several efforts have been made in the area to improve the poor visibility issue [5], still poor visibility is a major challenge and has negative effects on supply chain networks performance [8,30,45]. Table 1 summarizes some of the existing models that have been proposed for the poor visibility issue.…”

“…Given the globalization and expansion in the supply chain operations, the complexity of chain operations have been increased [1][2][3][4]. Due to the decentralized nature of the supply chain, firms are unable to identify the origins of problems that arises within their supply chain flow [5]. For instance, the recall of millions of toys in Mattel (an American multinational toy manufacturing company) in 2015.…”
Due to the increasing complexity of supply chains over the past years, many factors significantly contribute to lowering the supply chains performance. Poor visibility is one of the major challenging factors that lowers supply chains performance. This paper proposes a Blockchain-based supply chain network model to improve the supply chain visibility. The model focuses in improving the visibility measurements properties: information sharing, traceability, and inventory visibility. The proposed model consists of information sharing, traceability, and inventory visibility platforms based on Blockchain technology smart contract. The model built with Hyperledger platform and extend the Hyperledger Composer Supply Chain Network (HCSC) model. The research is designed to three main phases. First phase: the preliminary phase which is the literature review phase to identify the existing challenges in the domain. The second phase: the design and implementation phase which is the development steps of the proposed research model. The third phase: the evaluation phase which represent the performance evaluation of the proposed model and the comparisons between the proposed model and the existing models. In the evaluation performance, the common performance metrics Lead time and average inventory levels will be compared in the proposed model, Cloud-based information system, and the traditional supply chain. These proposed platforms offer an end-to-end visibility of products, orders, and stock levels for supply chain practitioners and customers within supply chain networks. Which helps managers' access key information that support critical business decisions and offers essential criteria for competitiveness and therefore, enhance supply chain performance.

“…The existing literature enlists plenty of studies claiming benefits of supply chain ecosystems (Blackhurst et al 2005;Caridi et al 2014;Kim and Lee 2010;Swift et al 2019). Sharing information within a supply chain improves performance, for instance, by minimizing the bullwhip effect as well as inventory costs (Yu et al 2001;Lee and Wang 2005;Lee and Whang 2000;Kim et al 2016).…”
Decision-making supported by digital ecosystems has been increasingly studied during recent years, especially due to improved technical capabilities to collect, store, and analyze large amounts of data. The literature recognizes that these systems can reduce response time of managers and enhance a cost-efficient recovery of supply chains. However, there is a lack of methodological frameworks to evaluate the benefits of these platforms. In addition, there is still little understanding of the risks in ocean container transport and their implications for supply chains. This paper proposes and applies a mathematical model for evaluating the impacts of digital platforms, with a focus on solutions to mitigate risks in sea transport operations. The model is based on scenarios and decision tree models to evaluate the impacts of a supply chain digital ecosystem on full containers shipped from Asia to Europe implemented by four companies. Results show monetary savings per scenario in the range from €3448 to €79,242. The most significant savings are expected on unplanned transshipments, cargo damage, export inspections, container detention, and container release.
“…For instance, firms with high visibility into their conflict minerals supply chains achieve higher profitability than firms with less visibility. Moreover, firms with high visibility into their conflict minerals supply chains realize improved sales performance and stock market valuations (Swift, Guide, & Muthulingam, 2019). As these relationships reflect a buying firm's upstream supply chain, we regard this as the vertical perspective of the supply network (T. Y.…”

“…The outsourcing of manufacturing can even cause a lack of control (Y. H. Kim & Davis, 2016;Serdarasan, 2013). Therefore, firms need to develop upstream visibility to exercise control over their supply chains (Swift et al, 2019). The need for supply chain transparency is high (Kashmanian, 2017).…”
Tobias and my two paranymphs Frederik and Vincent from Twente-as well as Holger, Andreas, Eika, Patrick, Colin, Constantina, Sebastian, Micha and Catja from Münster. While climbing different stages and enjoying good times together, I am glad that some of you became close friends of mine. Looking forward, several of you already completed their academic journey, while others are still on different heights of their mountains. Good luck to all of you in completing your projects-just keep climbing, I am sure you will make it! Special thanks go to my family-above all my mother Edith and my brother Benedikt. Thank you very much for your patience, understanding and unconditional support in the last years. You helped me keeping my motivation and recharging my batteries when energy was low. I could always count on you. This thesis is dedicated to you. Last but not least, I am very grateful to have my longtime friends Marina, Daniela, Laura, Anne and Vanessa from my hometown Wiedenbrück; the "Stuttgart Crew" Jule, Johanna, Martina, Kathrin, Eva, Bene and Konrad; and my dear friends Tatiana and Josiane in Münster. On my journey towards the top of the mountain, you always kept celebrating small stage victories with me and encouraging me when muscles were aching. All of you have been part of this exciting hike and joined me climbing it to the summit cross. Thanks a lot. Without you, this project would have been impossible.
