TL;DR: In this paper, the authors studied a vehicle supply chain and formulated four different modes of developing charging infrastructures for EVs when: (a) EV manufacturer invests in setting up the charging infrastructure with a government subsidy to EV consumers, namely the Model M, (b) Government invests in charging infrastructure and also provides a subsidy to EVs consumers, such as the Model MG, and (c) Government invested in the Model G.
Abstract: Electric mobility has emerged as a key initiative for the policymakers and the governments to mitigate the carbon footprint of the transportation sector. However, the adoption of electric vehicles (EVs) is slow, primarily due to the scarcity of adequate charging facilities. The intriguing factor in terms of developing charging infrastructure is related to which entity should invest in developing the same. Herein, we study a vehicle supply chain and formulated four different modes of developing charging infrastructures for EVs when: (a) EV manufacturer invests in setting up the charging infrastructure with a government subsidy to EV consumers, namely the Model M, (b) EV manufacturer invests in setting up the charging infrastructure, namely the Model R (c) Government invests in setting up charging infrastructure and also provides a subsidy to EV consumers, namely the Model MG, and (d) Government invests in setting up the charging infrastructure, namely the Model G. Our findings show that the Model MG and M are equally effective for generating the maximum EV demand and market share, thereby require maximum effort for developing the charging infrastructure. Further, social welfare is also maximum in these two cases, which is counterintuitive because government support is more in the Model MG as compared to the Model M. Hence, under a limited budget constraint, the government can provide direct subsidy to EV consumers and let EV manufacturer invests in charging infrastructure to maximize social welfare. Further, the Model MG and M have a lower overall environmental impact when GV's environmental impact is higher than a threshold. Additionally, we provide multifaceted policy recommendations for the government, along with manufacturer strategic choices under different scenarios.

TL;DR: In this article, a vendor-managed inventory (VMI) arrangement in a supply chain (SC), where the buyer imposes a penalty for shipments exceeding an upper limit, was considered, and the equivalence of VMI under deterministic demand with that of quantity discount models was established.
Abstract: In this paper, we have considered a vendor-managed inventory (VMI) arrangement in a supply chain (SC), where the buyer imposes a penalty for shipments exceeding an upper limit. We have shown as how the industry practice of VMI under penalty can be used as a SC coordination mechanism. The vendor can influence the buyer to increase the batch size without making the buyer worse off. We also discuss how such a penalty scheme may be derived. Further, we have established the equivalence of VMI under deterministic demand with that of quantity discount models, thus highlighting the need to incorporate both cooperation and coordination perspectives while analysing SC collaboration mechanisms.

TL;DR: Findings reveal that a combination of subsidy and green-tax can generate higher social welfare as compared to the use of only one of them under both monopoly and duopoly markets.
Abstract: The transport sector is one of the largest contributors to rising greenhouse gas (GHG) emissions in the world. With no tailpipe emissions, electric vehicles (EVs) can be one of the ways to reduce G...

TL;DR: A comparative analysis across four different forecasting models provides a new direction to envisage energy requirements and reveals different diffusion scenarios and possible policy measures to improve EV acceptances, especially in the presence of an uncertain environment like COVID-19.

TL;DR: A critical review of influential closed-loop supply chain research that takes a business economics perspective can be found in this article, where the authors offer a critical review and analysis of influential CLSC research.
Abstract: Research in closed-loop supply chains (CLSCs) has grown rapidly over the last 10 years. The authors offer a critical review of influential CLSC research that takes a business economics perspective. Much of the research was inspired by practice-driven thoughtpieces, and this helped to keep research focused on relevant issues. However, CLSC research has several assumptions, such as perfect substitution between new and remanufactured products that risk becoming institutionalized. There is a strong need to carefully examine current industrial practice so that research remains focused on relevant problems. Deeper understanding of consumer perceptions of remanufactured products, product diffusion, and valuation of returned products are needed for the field to continue to add insights into developing sustainable economies.

TL;DR: In this paper, the authors investigate the effects of carbon emission reduction on a supply chain with one manufacturer and two competing retailers for deteriorating products under vendor-managed inventory (VMI), which has not been fully studied in the existing literature.

TL;DR: In this paper, the authors used causal loop diagrams (CLDs) to simulate the performance of traditional and cloud-based hospital supply chains and compared the performance metrics: average inventory levels, lead time, and unfilled orders.

TL;DR: Three flexible subsidy contracts for VMI supply chains are proposed that enhance service levels, maximize SC performance, and share SC profits fairly, and help SC members to arrive at optimal price, revenue-sharing ratio, inventory target, subsidy rate.
