A scenario where the market demand is changed suddenly by some undesired events is considered. The results reveal that enhancing collaboration with a more resilient supplier can significantly improve supply chain resilience and reduce supply chain losses. It is also found that enhancing the supplier relationship can significantly benefit supply chain resilience if the collaborative intensity is relatively low, and it has less effect if supply chain members have already collaborated closely. Thus, enhancing the supplier relationship to a limited intensity is a relatively effective and economic method to strengthen supply chain resilience.展开更多

The value of demand information sharing is analyzed in a two-level supply chain involving one supplier-multiple retailer model in which retailer demands may be correlated. Each member in the supply chain forecasts its demand using an AR (1) demand process. Two conditions of the information sharing are considered (1) Without the information sharing, the retailers only communicate their orders to the supplier. (2) With the information sharing, retailers communicate their orders and forecasting models to the supplier. Analyses showthat the reductions of supplier's average inventory and average costs are substantial with the information sharing. However, the retailers donot get direct benefit from the information sharing. The retailers may ask the supplier to reduce the replenishment leadtime, so that the retailers will obtain substantial cost savings and inventory reduction. Both partners may obtain benefits when information sharing and leadtime reduction are implemented together.展开更多

We proof that using the general contract based on auction theory, i. e. the wholesale price contract, would not achieve the coordination of channel composed of the manufacturer and the winning supplier. The paper designs a contract mechanism, i.e. the side payment price-restricted contract based on auction theory, which not only ensures Pareto optimal solutions for both, but also coordinates the supply chain. A numerical experiment is provided to compare the performance of different auction mechanisms and to reinforce key managerial insights generated through analysis.展开更多

Further, this research aims to develop a measurement framework and pragmatically prove the framework through a measurement model. First, a factor structure for various constructs is made and the initial validity is determined from practicing managers and academicians. This research employs survey method and the data is collected from 358 supply chain professionals working in manufacturing firms in India. A measurement model is developed and proved with various tests of reliability and validity. Finally, three major latent constructs were formulated, namely, criterion of supplier selection, supply effort management and firm performance. The factor scores of these latent variables were used for further analysis. A six-stage approach was followed in the analysis of data. Firm performance was regressed against supplier selection criterion and supply effort management. The results indicate that the predictive variable has positive and significant effect on firm performance and they do not have any interaction and multicollinearity effects.展开更多

In Zambia, the Logistics Management Information System (LMIS) is a key tool for managing the supply chain of these commodities. This study aimed to evaluate the effectiveness of LMIS in ensuring the availability of essential medicines and medical supplies in public hospitals in the Copperbelt Province of Zambia. Materials and Methods: From February to April 2022, a cross-sectional study was conducted in 12 public hospitals across the Copperbelt Province. Data were collected using structured questionnaires, checklists, and stock control cards. The study assessed LMIS availability, training, and knowledge among pharmacy personnel, as well as data accuracy, product availability, and order fill rates. Descriptive statistics were used to analyse the data. Results: All surveyed hospitals had LMIS implemented and were using eLMIS as the primary LMIS. Only 47% and 48% of pharmacy personnel received training in eLMIS and Essential Medicines Logistics Improvement Program (EMLIP), respectively. Most personnel demonstrated good knowledge of LMIS, with 77.7% able to log in to eLMIS Facility Edition, 76.6% able to locate stock control cards in the system, and 78.7% able to perform transactions. However, data accuracy from physical and electronic records varied from 0% to 60%, and product availability ranged from 50% to 80%. Order fill rates from Zambia Medicines and Medical Supplies Agency (ZAMMSA) were consistently below 30%. Discrepancies were observed between physical stock counts and eLMIS records. Conclusion: This study found that most hospitals in the Copperbelt Province of Zambia have implemented LMIS use. While LMIS implementation is high in the Copperbelt Province of Zambia, challenges such as low training levels, data inaccuracies, low product availability, and order fill rates persist. Addressing these issues requires a comprehensive approach, including capacity building, data quality improvement, supply chain coordination, and investment in infrastructure and human resources. Strengthening LMIS effectiveness is crucial for improving healthcare delivery and patient outcomes in Zambia.展开更多

文摘A supply chain resilience model is established based on the biological cellular resilience theory to analyze the impact of the supplier relationship on supply chain resilience. A scenario where the market demand is changed suddenly by some undesired events is considered. The results reveal that enhancing collaboration with a more resilient supplier can significantly improve supply chain resilience and reduce supply chain losses. It is also found that enhancing the supplier relationship can significantly benefit supply chain resilience if the collaborative intensity is relatively low, and it has less effect if supply chain members have already collaborated closely. Thus, enhancing the supplier relationship to a limited intensity is a relatively effective and economic method to strengthen supply chain resilience.

文摘The widespread application of new-generation information technologies has driven the continuous development of supply chain finance in terms of expanding the credit base,precise risk control,and diversifying financing channels.In response to this trend,the government has successively introduced a number of policies aimed at regulating,guiding,and supporting the healthy and orderly operation of supply chain finance.These policies include improving public data open platforms,optimizing the regulatory system,strengthening risk governance,accelerating the construction of exchanges,improving the unified registration and information disclosure system,and introducing relevant supporting policies.To further promote the high-quality development of supply chain finance,it is necessary to continuously improve the risk-control system,ensure the stable operation of the financial market,enhance financial governance capabilities,adapt to dynamic market changes,and improve the information disclosure mechanism to provide institutional support for the construction of the data credit system.
文摘In recent years,with the advent of the digital era,digital transformation has become a mainstream social trend.As a powerful driving force,digital transformation is profoundly changing the operation mode and management method of enterprise supply chains.Enterprises should seize this opportunity to continuously enhance supply chain resilience.Enhancing enterprise supply chain resilience based on digital transformation can not only improve the supply chain’s resistance and recovery capabilities,but also further enhance its innovation capability.This helps enterprises better respond to various unstable factors and provides protection for promoting the sustainable development of the supply chain.In this regard,this paper first expounds the multi-dimensional value of digital transformation in enhancing enterprise supply chain resilience,and then puts forward effective paths,aiming to provide certain reference for relevant researchers.
文摘To explore the impact of partial centralization on supply chain performance,this study constructs a two-period game model of a closed-loop supply chain involving a manufacturer and an online retail platform participating in the trade-in strategy.Through mathematical modeling and numerical simulation methods,the optimal decisions were analyzed under conditions where the manufacturer partially owns the retail platform’s partial equity.This study finds that partial centralization yields the highest profits,followed by full centralization,with decentralized decisions yielding the lowest profits.Moderate centralization enhances overall profits by optimizing incentive mechanisms,whereas excessive ownership concentration reduces the flexibility of the retail platform,leading to a decline in profits.Additionally,product durability and trade-in subsidy significantly influence supply chain profitability:high-durability products reduce renewal frequency,while trade-in subsidy effectively stimulates consumer demand and increase overall profits.This study provides theoretical support and practical guidance for companies implementing the trade-in strategy.
