In this paradigm, PAV owners make decisions on whether/when/where/for how long to share their PAVs, which would make a dynamic fleet of SPAVs. To improve the effectiveness of such a mobility system, a certain fleet of shared business-owned autonomous vehicles (SBAVs) may also be required. This study proposes a bi-level programming model considering the hybrid ownership of shared autonomous vehicles (SAVs). The upper level optimizes the fleet size of SBAVs and rental price of SAVs involving an endogenous fleet of SPAVs, and the lower level involves an SAV self-relocation strategy and attends to travelers’ daily activity-travel scheduling behaviors. A memetic algorithm involving iterative adjustments of the supply and demand sides is developed for the bi-level model. Results from numerical examples indicate that SBAVs provided by the operator complement SPAVs to serve the mobility demand to improve system performance, while PAVs owners adapt sharing behaviors and daily schedules to reduce activity-travel disutilities.","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"2 1","pages":""},"PeriodicalIF":10.6,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The supplier receives all retail revenue in the former but incurs a channel entry cost. In the latter, the supplier pays the platform commission based on the resulting sales revenue, and the platform may share its demand information with the supplier. We consider two quantity leadership structures: supplier-led and platform-led. First, we show that the platform employs a linear quantity decision rule in equilibrium when there is information asymmetry. Second, a quantity-leader platform always shares its information with the supplier via the commission channel, whereas a quantity-follower platform may not have any incentive to do so. Third, regardless of who the quantity leader is, the supplier always encroaches via the commission channel if the retail-channel entry cost is high and encroaches via the retail channel if that cost is low. Quantity leadership significantly impacts the supplier’s encroachment channel selection only when the retail-channel entry cost is moderate. In this situation, a quantity-leader supplier prefers retail (commission) encroachment, whereas a quantity-follower supplier prefers commission (retail) encroachment when the commission rate is low (high). Last, we consider an extended model that focuses on the simultaneous quantity competition game, and our results characterize the conditions where the supplier is less likely to choose the commission channel in a simultaneous game than in a sequential game.","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"214 1","pages":""},"PeriodicalIF":10.6,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within this dynamic process, the load redistribution behaviour is the core countermeasure for the propagation of cascading failures, however the diversified mechanism has not been systematically studied. To fill in these gaps, this study aims to develop a pioneering resilience analysis framework against cascading failures, to comprehensively explore the impact of port disruptions on the shipping network resilience. By pioneering the influence analysis of port betweenness, weight, and connectivity on load determination and target selection, a port importance assessment method is applied as the foundation for load redistribution decisions. Based on the global service routes data from 2020 to 2023, the GCSN resilience against the sequential cascading failures of 686 ports worldwide is quantified by three metrics. A scenario analysis is conducted to simulate the effects of cascading failures triggered by 5 historical port disruption events (e.g., the COVID-19 port lockdowns and the 2024 bridge collision at Baltimore port) on resilience of the network. Determining the identified critical capacity threshold is pivotal for effectively enhancing the system’s resilience and preventing the likelihood of cascading failures. Additionally, this study offers cutting-edge perspectives to the global shipping industry stakeholders. It presents distinct strategies and preferences, offering actionable advice for port authorities in their risk response decisions. Moreover, this study delivers an economic rationale and critical evaluations, instrumental for the strategic maintenance, planning and augmentation of port infrastructures to prevent unforeseen risks.","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"71 1","pages":""},"PeriodicalIF":10.6,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is critical but remains challenging to understand and predict DM performance in transport, because operators’ mental states have not been effectively considered in complex DM processes such as ship anti-collision operations. This paper proposes an advanced decision support methodology that pioneers the incorporation of objective neurophysiological and subjective data to analyse functional connectivity in the brain and predict DM performance in ship navigation. Experiments were conducted using a functional Near-Infrared Spectroscopy (fNIRS) technology to explore the functional connectivity of two groups (low workload and high workload) and predict their DM performance in a ship collision avoidance situation. It brings brain science into transport engineering and the results generate new contributions to the existing knowledge, including (1) the establishment of a methodology to detect different workload levels in safety–critical transport systems using psychophysiological measurement; (2) analysis of brain’s functional connectivity of different groups of decision makers (e.g., seafarers) with high and low workload tasks; (3) an advanced methodology to assess human reliability in complex scenarios and predict operational behaviours; (4) pioneering a human-centred approach to predict DM performance and demonstrate its feasibility in shipping. From a practical perspective, stakeholders can utilise the findings of this study to rationally evaluate human performance in transport system operations, aiding in operator qualification and certification processes.

Telehealth has significantly improved chronic patients’ health by providing convenient, accessible, and personalized care, ultimately reducing hospital readmissions and improving patient outcomes. This research investigates the strategic collaboration between a physical hospital and an internet enterprise in developing a telehealth platform for chronic disease patients’ follow-up visits. We examine how government reimbursement policies and revenue-sharing contracts affect this collaborative model’s optimal pricing and performance. Using a four-stage sequential game theory model, we analyze two specific revenue-sharing contracts: capacity-based and volume-based. The study considers both homogeneous and differentiated reimbursement mechanisms, examining their influence on hospital profits, social welfare, and patient choice. Our findings demonstrate that volume-based contracts facilitate mutually beneficial collaborations, while capacity-based contracts favor hospital profitability. Homogeneous reimbursement has a limited feasible range and results in lower hospital profits and moderate social welfare. Differentiated reimbursement, coupled with the volume-based contract, maximizes social welfare by providing increased reimbursement for online patients and mitigating perceived value differences. This highlights the need for governments to prioritize differentiated reimbursement and volume-based contracts for robust and socially beneficial telehealth platforms. However, enhancing patient trust in the telehealth platform’s medical quality remains crucial for healthcare supply chain development under homogeneous reimbursement.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103864"},"PeriodicalIF":8.3,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study incorporates LTS into the design of supply chain finance schemes, considering the manufacturer’s financial constraints. To this end, we compare LTS and two types of low-carbon technology licensing (LTL) schemes, namely, royalty fee licensing (LTL-V) and royalty fee portfolio fixed-fee licensing (LTL-V+F), to reveal the value of LTS to capital-constrained supply chain and the government. The conclusions indicate that boosting unit royalty rates with a high consumer’s low-carbon preference, as well as fixed fee are not conducive to the increase of manufacturers’ order quantity. Compared to manufacturer independent financing benchmark scenario and any LTL scheme, the LTS scheme can not only achieve higher unit carbon emission abatement, but also potentially lower total carbon emissions.

The results show that firms have the same disclosure motivation when the platform pursues profit maximization because only the agency channel is retained in the supply chain, and firms share profits equally. However, the indistinguishable disclosure incentive for firms exhibits a convex relationship with the consumer surplus concern in the dual-purpose case. In addition, the M-C or P-C format is the optimal disclosure preference for firms, indicating that hitchhiking may not always be the best option. Specifically, the manufacturer (platform) will proactively disclose information in regions where the commission rate is low (high) and the consumer surplus concern is not too high. Firms in these areas have common preferences regarding different disclosure formats. Also, consumers do not necessarily benefit from the increased consumer surplus concern under the P-C format.
