The members in a liner alliance often have different shipping resources, indicating that they have to coordinate the shipping resources with each other, in order to achieve smooth cooperation. During the coordination, the fairness of members cannot be ignored as it forms the foundation of cooperation stability. Meanwhile, the vessel fleet is often heterogeneous in practice, not homogeneous assumed in most of existing studies. Therefore, this research explores the joint optimization problem of heterogeneous vessel fleet co-management (including fleet co-deployment, vessel co-scheduling, vessel co-sequencing, slot co-chartering and slot co-allocation), taking into account profit-sharing agreement and weekly-dependent demand. In response to this problem, a mixed-integer nonlinear program is first formulated with the goal of maximizing the overall profit reached by the alliance. We then linearize this nonlinear program, and subsequently develop a solution method to identify the optimal solution for the linearized model. Various numerical tests are performed to examine the validity of the proposed model. Furthermore, several managerial insights that support the operation of liner alliance are delivered.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"194 ","pages":"Article 103880"},"PeriodicalIF":8.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816524","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}

In this system, parcel lockers (PLs) are positioned in PT stations, through which small and light parcels are allocated to passengers for delivery to their final delivery addresses (i.e., performing the last-mile delivery). A probabilistic mathematical model is formulated with behavioural constraints to estimate the probabilities of accepting CS tasks by passengers. The probability is estimated based on a logit function, sensitive to the parcel’s weight, reimbursement amount, and the walking detour required to deliver the parcel to its final destination. The logit model is constructed based on survey data collected from the Greater Sydney (GS) area, Australia. The mathematical model optimises the allocation of delivery tasks to the CS system and PLs, subsequently, incentivising CS-allocated tasks for participating passengers. Furthermore, the model performs the routing of vehicles to deliver non-allocated parcels, including heavy parcels. A heuristic solution algorithm is then proposed to optimise decisions related to allocation, routing, and incentivisation, which was tested on a real case study. By conducting sensitivity analysis on various model parameters, results show that for a small carrier, utilising a PT-based CS system could minimise daily delivery costs by up to 36%, depending on passengers’ rate of familiarity with the CS initiative and the number of PT stations equipped with PLs. Vehicle delivery cost in the CS-integrated delivery system is also reduced between 50% and 65%, in comparison to the conventional vehicle-only system. Our study reveals that a CS system should offer higher incentives at the beginning, and as CS familiarity grows, figures could be reduced depending on other market and operational conditions. Furthermore, simulated experiments suggest that denser PL networks enable carriers to reduce incentives even at earlier stages with lower familiarity rates.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"194 ","pages":"Article 103916"},"PeriodicalIF":8.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816527","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}

Geo-fenced systems have emerged to mitigate these problems by restricting LSEVs to designated areas. However, integrating these infrastructures effectively remains challenging due to regulatory, convenience, and operational hurdles. In this study, we introduce a facility location optimization problem that strategically places Micro-Mobility Service Facilities (MMSFs) that enable charging, parking, and battery swapping of LSEVs. A utility model with benefit and loss functions accounts for the multiple objectives in this problem, including the impact of MMSF placement on service coverage and user convenience as well as financial and logistical costs. This model is uniquely customizable, allowing urban planners to modify the utility function’s parameters to align with specific local priorities and regulatory conditions. To solve this facility location optimization problem, we present a Deep Reinforcement Learning (RL) method that iteratively learns optimal placement strategies for Micro-Mobility Service Facilities by simulating interactions within real-world urban road networks and adapting to user demand patterns, regulatory constraints, and operational efficiencies. Our experiments in Austin and Louisville demonstrate that strategic placement of these facilities leads to substantial enhancements in infrastructure coverage, with improvements in parking demand by up to 163% in Austin and 72% in Louisville. These results underline the role of our approach in fostering more equitable and efficient urban mobility systems, significantly exceeding traditional simulation-based methods in both coverage and operational logistics. In particular, the results based on various budget scenarios reveal that service coverage and accessibility can be improved, with diminishing returns at higher budget levels due to demand saturation.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"194 ","pages":"Article 103872"},"PeriodicalIF":8.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142788853","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}

Particularly, the manufacturer’s design of the product’s attributes would affect the conversion rate of the customers who click the web links to the product, and customer demand for the product eventually. The manufacturer jointly plans the product design and inventory control in this model. By exploring the model, we demonstrate that the manufacturer makes inventory decisions following a modified base-stock policy dependent on the conversion rate, and adjusts the product design as the inventory cost rate increases. Furthermore, we find the manufacturer’s separate plan of product design and inventory control harms the manufacturer but can benefit the retail platform and the entire supply chain. This finding can explain why the manufacturer’s separate plan is a widely observed phenomenon in practical C2M programs.

The RT-VR&amp;CS problem aims to develop a fast and robust algorithm to determine the real-time relocation and charging strategies for electric vehicles (EVs) with the goal of maximizing the profit of carsharing operators. A dynamic algorithmic framework based on a rolling time horizon is first established. Specifically, the entire planning horizon is divided into a series of sub-horizons, and a static vehicle relocation and charging strategy (S-VR&amp;CS) problem is subsequently addressed over each sub-horizon in regard to the latest rental information known up to the beginning of the sub-horizon. For each static problem, we employ a set-packing-type formulation and a column-generation-based solution method. In particular, a multi-label method is developed to generate activity trajectories (i.e., columns) incorporating vehicle relocation and charging strategy for the first static problem, whereas the activity trajectories for the subsequent static problems are efficiently generated in an online environment by leveraging the existing activity trajectories generated for the previous static problem and employing a reactive column generation process. Numerical experiments on randomly generated instances and a case study based on a one-way carsharing company in China, i.e., EVCARD, are conducted to demonstrate the efficiency of the proposed solution method.

A backward induction method is employed to conduct a comparative analysis of social welfare between group management and localized management strategies for multi-airport systems. The results demonstrate that the group management strategy represents the Nash equilibrium, as it ensures the maximization of social welfare while maintaining alignment with public welfare objectives. Further examination of high-speed rail unit operating costs reveals a potential Prisoner’s Dilemma that the management departments may encounter. When the high-speed rail unit operating costs fall below a critical threshold, total social welfare under the localized management strategy surpasses that of the group management strategy for multi-airport systems. Moreover, higher airline revenue proportions derived from air-rail intermodal services may mitigate the likelihood of encountering a Prisoner’s Dilemma, as the critical value of high-speed rail unit operating cost increases with the increase of airline revenue proportions.

Considering the platform can flexibly set the quality standard, we explore the quality certification for the platform where the quality and price decisions of the heterogeneous manufacturers can be affected. We find that the certification is profitable (unprofitable) for platform when the certification cost coefficient is low (high). Additionally, we identify two effects of the consumer preference on the certification: the low-preference effect and the high-preference effect, which have opposing impacts on the standard and the quality investment of certified manufacturers. Interestingly, smaller differences in brand positioning enhance the high-preference effect, which reflects the complementary role of the high-preference effect in expanding product vertical differentiation. Moreover, when implementing the certification, the platform may prefer to encourage only the high-end manufacturer to participate in the certification, as the different impacts of two preference effects render certification unprofitable for the low-end manufacturer. More interestingly, we find that the introduction of quality certification has a two-fold effect. It incentivizes participant (non-participant) to enhance (degrade) its product quality and price.

First, we present that retailer financing can lead to a “win–win–win” situation for the manufacturer, retailer and consumers, as the firms’ capital flows within the whole supply chain and boosts the production output. Second, we find that, in the presence of asymmetric quality information between the retailer and manufacturer, the retailer may provide financing services to motivate an informed manufacturer to initiatively share quality information. The strategic information sharing becomes dominant when the manufacturer’s production cost is high and initial capital is moderate.
