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. Furthermore, it is critical for adaptive automation regarding DM support in safety–critical systems.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103861"},"PeriodicalIF":8.3,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. Owing to the effective increase in expected environmental revenues, the government’s revenue under LTS may also increase significantly in some cases.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103827"},"PeriodicalIF":8.3,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637372","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}

We elaborate on two disclosure formats: the P-C format, in which the platform discloses quality information, and the M-C format, in which the manufacturer discloses quality information. 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.

Compared with stable long-term contract demands, spot container shipping demands are often unstable due to their high frequent cancellations during the slot booking period and their uncertain arrivals even no-shows. This poses a challenge for shipping companies in making precise and profitable decisions on slot allocations for these spot demands, to avoid the loss of slot utilization and shipping profit. This paper thus focuses on a dynamic slot allocation problem for spot containers with consideration of their random arrivals and cancellations during the booking period to maximize the expected shipping profit, and formulates it as a Markov decision process (MDP) model. Due to the well-known curse of dimensionality of MDP models, this paper uses the approximate dynamic programming (ADP) approach to approximate our MDP model, and consequently develops a series of stochastic programming models, which can yield a near-optimal slot allocation policy. Numerical experiments are conducted to examine the effectiveness and superiority of our models obtained by the ADP approach. The computational results show that our dynamic slot allocation strategy can make shipping companies achieve a high slot utilization rate, up to 91.36 %. Furthermore, compared with various slot allocation policies commonly used by shipping companies in practice, the policy obtained by the approach used in this paper performs best in terms of profit, with an improvement of up to 33.26 %.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103837"},"PeriodicalIF":8.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637381","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}

Given that there are more product varieties online than offline and competitive online marketplace, it remains unclear how retailers identify products that should be offered as hybrid versus online-exclusive. Comparing to online exclusive selling strategy, two key features of the hybrid selling strategy are captured: the <em>demand expansion</em> and <em>profit margin effects</em>. The demand expansion effect refers to the phenomenon where a retailer, transitioning from an online-exclusive approach to a hybrid approach, can expand market size by appealing to consumers who exclusively prefer offline purchases. Besides, the profit margin effect relates to how customer migration impacts retailer profits due to the disparity in unit product profit margins between online and offline channels. We reveal that the products with significant demand expansion effect should be offered as hybrid, and the hybrid selling strategy is efficient in preventing supply encroachment. However, even if the profit margin and demand expansion effect are positive, the products may be better to offer as online-exclusive. This is because, under the hybrid selling strategy, the supplier would charge a high wholesale price to squeeze the retailer’s profit. Consequently, the hybrid selling strategy in this circumstance intensifies the double marginalization effect, prompting the retailer not to opt for the hybrid selling strategy as a means to prevent supplier encroachment. Finally, the cross-selling effect, in which the customers buy some other products, strengthens the profit margin effect, and the results remain robust. Therefore, our study provides management insights that high-volume products may also be offered as online-exclusive, which challenges previous findings based on the long-tail phenomenon.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103853"},"PeriodicalIF":8.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637374","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 problem is how the routing and scheduling of trucks should be determined to take full advantage of truck platooning and minimize the total transportation cost. We propose two model formulations over a time-expanded network for this problem: a direct delivery model and an indirect delivery model, where the indirect delivery model allows trucks to visit intermediate locations during deliveries to facilitate the formation of platoons. In both models, trucks are permitted to wait at any traversed node provided that time windows of requests are not violated. We develop an improved dynamic discretization discovery (DDD) algorithm to solve the two models exactly. Through extensive computational experiments, we find that (1) the improved DDD algorithm can increase solution accuracy with much less computational effort compared with the basic DDD algorithm; (2) the cost-saving effect of truck platooning is favorable; and (3) for freight companies operating on small transportation networks, using the direct delivery model may be more appropriate.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"193 ","pages":"Article 103846"},"PeriodicalIF":8.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637376","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}
