Fairness in online vehicle-cargo matching: An intuitionistic fuzzy set theory and tripartite evolutionary game approach

This paper explores the concept of fairness and equitable matching in an on-line vehicle-cargo matching setting, addressing the varying degrees of satisfaction experienced by shippers and carriers. Relevant indicators for shippers and carriers in the on-line matching process are categorized as attributes, expectations, and reliability, which are subsequent quantified to form satisfaction indicators. Employing the intuitionistic fuzzy set theory, we devise a transformed vehicle-cargo matching optimization model by combining the fuzzy set's membership, non-membership, and uncertainty information. Through an adaptive interactive algorithm, the matching scheme with fairness concerns is solved using CPLEX. The effectiveness of the proposed matching mechanism in securing high levels of satisfaction is established by comparison with three benchmark methods. To further investigate the impact of considering fairness in vehicle-cargo matching, a shipper-carrier-platform tripartite evolutionary game framework is developed under the waiting response time cost (WRTC) sharing mechanism. Simulation results show that with fairness concerns in vehicle-cargo matching, all stakeholders are better off: The platform achieves positive revenue growth, and shippers and carriers receive positive subsidy. This study offers both theoretical insights and practical guidance for the long-term and stable operation of the on-line freight stowage industry.Comment: 36 pages, 15 figure

Mapping of Strategic Factors for 2nd Life Battery Repurposing: A qualitative multiple case study of Norwegian actors

Policies for energy efficiency and renewable energies, as well as consolidating CO2 standards for vehicles, have been implemented to achieve climate targets set by The Paris Climate Agreement. In recent years these actions have led to a boost in the global electrification of the transport sector, and hence Electric Vehicles (EVs). In Norway, EVs represented a market share at 55% in 2020, making the country a first-mover internationally. A Lithium-Ion Batteries (LIB) is removed from the EV when the retaining capacity drops below 80%, which will lead to an increase of decommissioned LIBs in the future. In recent years, the amount of End of Life (EoL) batteries has been seen as a business opportunity, giving rise to several start-ups employing decommissioned EV batteries in second-life applications. This thesis aims to cover a gap in the research literature, focusing on contributing valuable insight with empirical data from the Norwegian repurpose market. Through a qualitative multi-case study design, a selection of established businesses, either directly or indirectly connected to the Norwegian repurpose market, were studied. Findings mapped out strategic factors for repurposers and identified barriers and drivers in the Norwegian repurposing market. The use case of second-life batteries, channels for sourcing second-life batteries, and how the different cases can overcome barriers in the market proved to be the most influential factors. Barriers within the second-life battery market occur due to a lack of market structure and national regulatory standards. Moreover, empirical evidence shows a need for governmental facilitation to expand the market for second-life battery repurposing

The Impact of Demand Uncertainty on Consumer Subsidies for Green Technology Adoption

This paper studies government subsidies for green technology adoption while considering the manufacturing industry’s response. Government subsidies offered directly to consumers impact the supplier’s production and pricing decisions. Our analysis expands the current understanding of the price-setting newsvendor model, incorporating the external influence from the government, who is now an additional player in the system. We quantify how demand uncertainty impacts the various players (government, industry, and consumers) when designing policies. We further show that, for convex demand functions, an increase in demand uncertainty leads to higher production quantities and lower prices, resulting in lower profits for the supplier. With this in mind, one could expect consumer surplus to increase with uncertainty. In fact, we show that this is not always the case and that the uncertainty impact on consumer surplus depends on the trade-off between lower prices and the possibility of underserving customers with high valuations. We also show that when policy makers such as governments ignore demand uncertainty when designing consumer subsidies, they can significantly miss the desired adoption target level. From a coordination perspective, we demonstrate that the decentralized decisions are also optimal for a central planner managing jointly the supplier and the government. As a result, subsidies provide a coordination mechanism

Shifting Gears: Industrial Policy and Automotive Industry after the 2008 Financial Crisis

Apart from being one of the hardest hit sectors during the 2008 financial crisis, the auto sector is also a prominent sector where emerging auto markets such as China have fared relatively well compared to their competitors in North America and Europe. This paper examines various ways that nations have shifted their policy gears to revive and restructure the automotive industry by using the case studies of the USA, France, and China. New sets of policy initiatives are contingent on particular industrial and institutional contexts, but both developed and developing countries have employed wide range of “murky” protectionist measures. This makes it unlikely for the WTO member countries to take a naming and shaming approach and file a case at the WTO level, which poses challenges to the WTO rules and trade liberalization

Game-theoretic analysis to examine how government subsidy policies affect a closed-loop supply chain decision

The pros and cons of government subsidy policies in a closed-loop supply chain (CLSC) setting on optimal pricing, investment decisions in improving product quality, and used product collection under social welfare (SW) optimization goal have not been examined comprehensively. This study compares the outcomes of three government policies under manufacturer-Stackelberg (MS) and retailer-Stackelberg (RS), namely (i) direct subsidy to the consumer, (ii) subsidy to the manufacturer to stimulate used product collection, and (iii) subsidy to the manufacturer to improve product quality. Results demonstrate that the greening level, used product collection, and SW are always higher under the RS game, but the rate of a subsidy granted by the government is always higher under the MS game. Profits for the CLSC members and SW are always higher if the government provides a subsidy directly to the consumer, but productivity of investment in the perspective of the manufacturer or government are less. In a second policy, the government organizations grant a subsidy to the manufacturer to stimulate used product collection, but it does not necessarily yield the desired outcome compared to others. In a third policy, the manufacturer receives a subsidy on a research and development (R&D) investment, but it yields a sub-optimal greening level. This study reveals that the outcomes of subsidy policies can bring benefit to consumers and add a degree of complication for CLSC members; government organizations need to inspect carefully among attributes, mainly product type, power of CLSC members, and investment efficiency for the manufacturer, before implementing any subsidy policies so that it can lead to an environmentally and economically viable outcome
