Being overly conservative in allocating items at the beginning of the supply chain to save stock for fulfilling demand further down the supply chain increases the likelihood of unallocated items (waste). On the other hand, fully addressing the demand of nodes in the earlier stages of the supply chain may negatively impact the equity of the allocation policy, as downstream nodes may receive significantly fewer items in proportion to their demand. This study proposes a framework for modeling the sequential decisions involved in this online resource allocation problem as a Markov Decision Process (MDP). Given that the size of the state–action space can become very large for this problem, standard dynamic programming methods in the reinforcement learning domain reach their limits, so using Approximate Dynamic Programming (ADP) is a practical solution. In this study, two methods of measuring downstream uncertainty are proposed, and Policy Function Approximation (PFA) is used to develop an optimal allocation policy.

We examine two dimensions of blockchain’s role in mitigating information asymmetry within supply chains. We focus on (i) the disparity in quality information between the manufacturer and retailer, and (ii) the discrepancy in quality information between consumers and the product. We find that if both the manufacturer and the retailer raise prices simultaneously due to blockchain adoption, the manufacturer should avoid claiming that the product quality is very high or low. When consumer trust in product quality is moderate and the benefits of blockchain are moderate, the value of blockchain is realized more at the production stage. Conversely, when consumer trust is either very low or very high and the blockchain benefits are substantial, the value of blockchain shifts to the retail stage.

A common restriction is referred to as low emission zone (LEZ) where ICEVs are either banned from entering or required to pay a daily toll to enter, whereas green vehicles such as electric vehicles (EVs) are exempt from any access restriction and toll payment. Therefore, delivery companies operating in LEZs face new challenges to determine their fleet configurations and make route plans. In this paper, we tackle this issue by adopting an optimization-based approach, which deals with routing a mixed fleet of vehicles that serves customers located inside and outside the LEZ. The fleet consists of ICEVs and EVs that are allowed to recharge en route. The objective is to minimize total operating costs that comprises the charging cost of EVs, fuel cost of ICEVs, and tolls paid by ICEVs that enter the LEZ. We present the mixed integer linear programming formulation of the problem and use it to solve small-size instances. For solving large-size instances, we develop an Adaptive Large Neighborhood Search method that benefits from new problem-specific mechanisms.

Aircraft recovery problem (ARP), which provides aircraft recovery plans for airlines, is one of the most important problems in airline disruption management. This paper develops a robust aircraft recovery model (RARM) with considering slot resource, airport capacity and maintenance flexibility. To increase the robustness of recovery plans, we reduce the number of critical and loose connections. When the number of flights involved is large, there are too many variables and constraints in the RARM, making it difficult to solve. Then we propose alternating direction methods of multipliers (ADMM) combined with column generation method (CG) to solve RARM. Specifically, some complex constraints are relaxed by augmented Lagrangian method (ALM) and the relaxed problem is decomposed into multiple subproblems under the ADMM framework. Since the ADMM subproblems are nonlinear integer programs, we utilize the binary variable property and linearization technique to linearize them so that their computational difficulty is mitigated. We prove that the best extreme points of their linear relaxations are optimal to the subproblems, and then CG is used to solve the equivalent linear relaxations of subproblems. In our numerical experiments, the proposed model and algorithms are tested on real-world data. Computational results show that our methods can find robust aircraft recovery plans in reasonable time. For all instances, the total delay time caused by a new disruption is decreased with a maximum reduction of 37.46%.

A frequently used method involves setting up bins where consumers can return their used products. Despite their growing popularity, these programmes have received limited research attention. This research extends take-back literature by incorporating novel bin configuration considerations and evaluating the economic benefits of volume reduction technologies. We develop a detailed mathematical framework to determine the optimal reverse supply chain (RSC) strategies for take-back. We validate our model through a real-world case study implementation. Furthermore, by testing it across diverse global scenarios with various parameter combinations, we generate broadly applicable findings that advance both theoretical understanding and practical implementation. Our analysis reveals that optimal bin configuration varies by returns volume: mixed product streams in a single bin prove more economical at low-volume sites, while separate collection bins become advantageous at high-volume locations. The implementation of shredding technology emerges as a crucial cost-reduction strategy, that is particularly effective when deployed at high-volume storage facilities. For a wide range of experiments, transportation costs represent approximately half of optimised total expenses. Higher contamination levels in bins correlate with reduced transportation expenditure, but this brings increased disposal fees and negative environmental impact. Our findings recommend maintaining a mixed inventory of shredded and non-shredded materials at storage facilities, with selective transportation to recycling centres. The proposed models and recommendations provide practical decision-making tools for businesses seeking to optimise take-back operations, contributing to the broader implementation of circular economy principles for environmental performance.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"201 ","pages":"Article 104261"},"PeriodicalIF":8.3,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144329779","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}

Carbon emission at a container terminal is mainly from two sources: one is from vessels moored at the terminal, and another is from equipment to stevedore containers, like quay cranes (QCs) on quay-side platform, yard cranes (YCs) at yard, and trucks to transport containers. The berth allocation, QC/YC assignment, truck deployment and subblock reservation are the operations for vessels to moor and stevedore containers, and they mutually interact with each other, which consequently affect the stevedoring efficiency and the carbon emission. Particularly, QCs usually require routine maintenance for operational safety. Therefore, to explore this challenge problem encountered by port operators, this paper tries to integrate operations with QC maintenance under carbon emission tax, and formulates it as a mixed-integer nonlinear programming model. To solve the model on large-scale instances, a column generation (CG) based approach is developed. Finally, numerical experiments are conducted to verify the effectiveness of the proposed models and solution approach. The results indicate that the carbon taxation policy has significant impact on integrated operation plans, and can significantly reduce the carbon emission. Also, we compare the effects of stepwise and unitary carbon taxation policies on carbon emission reduction, and find the former performs better than the latter. In addition, computation results show that the proposed CG based approach has better performance compared with commercial solvers.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":"201 ","pages":"Article 104270"},"PeriodicalIF":8.3,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330493","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 study, four subsidy scenarios are examined: no subsidy, subsidizing the 1st port operator, subsidizing the 2nd port operator, and subsidizing both two port operators, with the goal of maximizing social welfare. The findings reveal that if the conversion degree of SSE construction is high, the absence of subsidies often results in a Prisoner’s Dilemma, where both two operators may engage in simultaneous SSE construction that is not economically viable. Although resorting to abandoning SSE construction can resolve this dilemma, government subsidies tend to reduce the likelihood of achieving both environmental and economic benefits simultaneously.
