Summary: This paper examines the relative impact of flexibility and redundancy on supply chain responsiveness, finding that the backup-suppliers practice is more effective than the flexible-suppliers practice. It also shows that adding some level of flexibility to a backup-suppliers practice can lower the expected total cost.

Summary: Supply Chain Management is constantly evolving, and Supply Chain Resilience (SCR) is a recent concept that has emerged from changes in business practices. However, there is still limited research on how to model and quantify SCR behavior. This study proposes a new resilient supply chain metric that is incorporated into an optimization model to maximize economic and responsiveness objectives. A case study is conducted to analyze the impacts perceived by downstream customers and to demonstrate the correlation between SC performance and the new SCR metric.

Summary: Market disruptions impact demand directly, and service providers in logistics supply chains must prepare service capacity before demand is known. This paper explores how to determine future service capacity based on market disruptions and the beneficial effects of elastic logistics on the supply chain. The analysis shows that elastic logistics can lead to positive outcomes regardless of the risk attitude.

Summary: Quality issues in supply networks can have negative impacts on suppliers and their downstream customers. In this study, we develop a novel modeling framework based on epidemiology to investigate how network structure affects the propagation of quality issues. The results show that the magnitude of a quality issue is strongly influenced by its origin node and the network archetype. Improving quality control at critical nodes and adjusting the network structure are effective strategies to mitigate the spread of quality issues.

Summary: This paper proposes a methodological approach for managing dependence and uncertainty in dynamic industrial scenarios, by studying the pandemic's effects on supply chains and analyzing the connections among effects and risks. The proposed approach utilizes the Analytic Network Process (ANP) to weight risks and the Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) to rank contingency strategies.

Summary: Firms are using blockchain technology to prevent fraudulent activities and identify data tampering in supply chains. However, a comprehensive review of blockchain application in building a cyber-secure and resilient supply chain is lacking. This study conducts a systematic literature review to assess the state of literature on the significance of blockchain in this context. The analysis reveals six dominant themes related to blockchain adoption and application, challenges, and benefits in the supply chain.

Summary: This paper applies stochastic optimisation of CVaR to maintain risk-averse viability and improve resilience of a supply chain under propagated disruptions. Two stochastic optimisation models are developed with conflicting objectives, and a stochastic mixed integer quadratic programming model is used to select a risk-averse viable production trajectory. The proposed approach is applied to smartphone manufacturing, and the findings show that more risk-aversive decision-making leads to a larger viability space and higher resilience of the supply chain. Single-objective decision-making may reduce supply chain viability.

Summary: The study uses Bayesian belief networks combined with the analytic hierarchy process and noisy-OR techniques to evaluate primary risks in the software supply chain, reducing the number of queries required of decision makers. By ranking software suppliers based on risk level, decision makers can select a low-risk supplier and gain a better understanding of risk factors in the SSC.

Summary: The COVID-19 pandemic has put the supply chains for medically critical items and common household goods to the test, particularly in terms of severe shortages of personal protective equipment (PPE) and ventilators in the United States. These shortages have revealed vulnerabilities in the supply chains of essential products during times of crisis, leading to public pressure on corporations to reconsider their supply chains. Drawing from lessons learned during the pandemic, this paper proposes a research agenda and opportunities to develop responsive supply chains to combat future pandemics and major public health emergencies.

Summary: This study focuses on the communication selection problem of autonomous sensors connected through the Internet of things, highlighting the role of environment state in mediating sensor quality and familiarity. When sensor qualities are public, sensors eventually settle on a constant target set, but this choice is influenced by past states. When sensor qualities are private, sensors may not settle on a constant target set.

Summary: This paper examines the implications of credit-based MSPs in a more general setting, involving two types of farmers and two types of crops. The study finds that strategic farmers can counteract the decisions of myopic farmers and that credit-based MSPs are more effective when the market is dominated by myopic farmers. Additionally, offering MSPs to complementary crops can result in a higher surplus.

Summary: Dual sourcing and contingent sourcing are important risk mitigation strategies for managing supply chain risks, particularly transportation-related losses of inbound orders. Shipment information, obtained through in-transit inspection points or monitoring technologies, enables contingent sourcing as a means of managing transportation risk. This study examines the impact of contingent sourcing and shipment information in a setting where a buyer can source from two competing suppliers.

Summary: When determining store locations, competing retailers need to consider customers' store choices. Incumbent retailers estimate customer attraction parameters using historical data, while new entrants can observe the location structure of incumbents to estimate these parameters. We propose an inverse optimization approach to help new entrants improve their profits by identifying parameter combinations that lead to observed equilibrium solutions.

Summary: The asymmetric market power between a firm and its partners negatively affects the firm's financial performance. Building relationships with suppliers or customers that have matched market power is the best approach. The strength of the buyer-supplier relationship amplifies the negative impact of asymmetric market power, while the level of relationship embeddedness reduces its negative effect. Moreover, firm-specific institutional, industry, and regional economic heterogeneities also influence the financial impact of asymmetric market power.

It examines the theory of coopetition and organizational relationships in intra-firm and inter-firm supply chains, focusing on collaboration between rival manufacturers. The study identifies structures and mechanisms of coopetition, such as buyer-supplier coopetition, supply networks coopetition, and production and distribution/logistics coopetition. It provides a holistic approach to SCC management practices and serves as a guide for future research.
