Consensus mechanisms such as Proof of Work (PoW) and Proof of Stake (PoS) are crucial for maintaining the decentralized and secure nature of blockchain networks, ensuring that all transactions are verified and consistent across the network. This is vital for preserving the integrity and reliability of Web 3.0 applications. This paper investigates the decision-making process involved in selecting between these two mechanisms. We find that platforms are more inclined to adopt a PoW-based system when mining costs are relatively low, indicating a strong correlation between cost efficiency and consensus choice. Furthermore, our analysis reveals that the optimal token reward from mining in a PoW platform and the token reward rate per validator in a PoS platform exhibit non-monotonic changes, suggesting complex interactions among various influencing factors. Notably, we identify two win-win scenarios where the system achieves both increased profitability and enhanced social welfare. Specifically, the PoW platform demonstrates superior performance in profit and social welfare when penalties for data processing capacity shortages are sufficiently high. Conversely, when these penalties are low, the PoS platform shows greater effectiveness in achieving both profit and social welfare. These findings provide valuable insights into the strategic considerations underlying the choice of consensus mechanisms in blockchain applications.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"200 ","pages":"Article 104173"},"PeriodicalIF":8.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089088","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}

However, despite the rapid growth of shared mobility platforms, ridesharing demand remains relatively low. To design appropriate network-based policies to stimulate ridesharing, solving the traffic assignment problem in the presence of ridesharing services serves as the first and fundamental step. In a general network with both car owners and non-car owners, this paper models travelers’ mode, ridesharing partner and route choices at ridesharing user equilibrium. The model allows each RS driver to serve riders between any of her/his reachable origin–destination (OD) pairs, ensures each RS rider is served door to door by one RS driver, and endogenously determines the RS driver/rider demand and ridesharing price between each OD pair. The model is formulated into a non-monotone variational inequality (VI) problem. To solve it efficiently on large-scale networks, we propose a tailored Benders decomposition-based approximation approach, which decomposes the VI problem into a subproblem and a non-monotone master problem. The subproblem is transformed into a convex programming problem, which is further equivalent to a Beckmann formulation with side constraints. And for the non-monotone master problem, we apply the constant approximation scheme to approximate it by solving a convex quadratic programming problem with off-the-shelf solvers. The convergence of the proposed algorithm is theoretically established, and the correctness of the model and the efficiency of the algorithm are demonstrated through numerical experiments based on small to large scale networks.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"200 ","pages":"Article 104140"},"PeriodicalIF":8.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089086","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}

Through the analysis of 386 firms in mainland China, we identify that SC digitalization can boost firm performance by serially enhancing ROCs and BMDs. Interestingly, a cross-industry analysis further reveals that while ROCs are crucial for both manufacturing and service firms in sustaining the performance outcomes of SC digitalization, distinct differences in BMDs emerge. Manufacturing firms primarily depend on novelty-centered BMD, whereas service firms integrate both types of BMDs.

This study addresses the integrated rescheduling problem in a high-speed railway network during severe disruptions, focusing on train routing, timetable adjustments, and passenger reassignment. We employ rescheduling strategies that allow disrupted trains to reroute through alternative paths within stations and across the network, utilizing remaining capacity to ensure reliable service for affected passengers. To tackle this issue, we propose a path-based mixed-integer linear programming (MILP) model based on detailed space–time networks, aiming to minimize total train delays and passenger inconvenience caused by disruptions. However, solving this integrated model using the column generation method presents convergence challenges as the problem scale increases. To address these challenges, we introduce a hierarchical solution framework with two main components: (1) a Benders decomposition-based procedure to iteratively capture the interaction between train rescheduling and passenger reassignment, and (2) two column generation procedures to explore promising space–time paths for both trains and passengers. Additionally, a dynamic constraint generation technique is integrated to further accelerate the solution process. Numerical experiments using real-world data from Chinese high-speed railway network validate the effectiveness of the proposed approach. The results show that our method delivers high-quality solutions within an acceptable time frame, efficiently reassigning passengers and rerouting trains during disruptions. Experimental findings also reveal that integrated modeling improves overall efficiency by 17.32% on average compared to sequential modeling. Furthermore, the proposed hierarchical algorithm significantly outperforms traditional column generation methods, reducing computation time by an average of 53.82%.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"200 ","pages":"Article 104177"},"PeriodicalIF":8.3,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067240","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}

However, the MDCEV model primarily focuses on activity choices that generate increased utility over time, overlooking the fact that travel, as a derived activity, is typically something people prefer to save time on. To bridge the research gap, we introduce the bi-mode utility multiple discrete–continuous extreme value (BMU-MDCEV) model. This model seamlessly integrates a diminishing function for travel with the classical utility function, underscoring the principle that individuals typically aim to minimize travel time. Inspired by the fact that both choice modeling and machine learning (ML) involve non-convex optimization processes, this study implements an ML-based computational graph (CG) mechanism to provide reliable and efficient parameter estimates for the proposed model. This approach emphasizes the integration of theory- and data-driven methods within the context of multiple discrete–continuous choices. Validated using the National Household Travel Survey (NHTS) 2017 dataset, the CG-enhanced BMU-MDCEV model effectively uncovers socioeconomic heterogeneity and captures the substitution and complementarity in time allocation patterns. Our analysis of the marginal utility of various travel types reveals a positive correlation between travel time tolerance and activity satiation for discretionary activities (e.g., leisure, shopping). Conversely, individuals tend to reduce unnecessary travel time for mandatory daily activities (e.g., home-based activity, work), regardless of the degree of activity satiation. By shedding light on the nuanced mechanisms behind individuals’ time allocation, our proposed method paves the way for informed transport management strategies that respond more effectively to individual behavior.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"200 ","pages":"Article 104154"},"PeriodicalIF":8.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067204","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 first analyze the promised delivery time decisions and the first-best expected profits of the two types of creators in the symmetric-information scenario. We then characterize an effective reimbursement rate, which is the minimal amount that a creator is required to pay for each delayed delivery, and find that this rate can fully prevent the delivery delay. In the asymmetric-information scenario, where the creator type is private information, we fully obtain the perfect Bayesian equilibrium by specifying the costly and costless separating equilibrium and the pooling equilibrium. Importantly, we demonstrate that the effective reimbursement rate mentioned earlier cannot prevent delays caused by a high-type creator’s distortion in determining the promised delivery time, highlighting the flaw of the reimbursement policy. Surprisingly, increasing a low-type’s delivery inefficiency degree always harms the low-type creator but does not necessarily benefit the high-type.

The decision-making of this problem is pivotal for the manufacturer, as it directly impacts after-sales service performance. This problem also represents a novel departure from conventional research, which traditionally treats pricing and inventory decisions in isolation under the assumption of predetermined contractor participation. We develop a two-echelon inventory allocation framework that jointly optimizes pricing and inventory decisions for each contract type. Through theoretical analysis, we demonstrate that the optimal contract choice critically depends on the number of participating contractors: semi-outsourcing proves superior with limited participating contractors, while full outsourcing becomes preferable as contractor availability increases.
