In this study, we designed a time-driven simulation–optimization framework that addresses the dynamic heterogeneous order-courier assignment problem and incorporates order-vehicle restrictions.

Extensive testing using literature instances demonstrated the framework’s ability to satisfactorily address the defined problem.

A generalized travel cost function incorporates the following disutility factors: monetary cost, day-to-day mean travel time, (un)reliability as represented by day-to-day 95th percentile travel time, crash risk, and physical discomfort. The proposed open-source tool can be used to create multimodal travel cost matrices, which may immediately serve as an input for accessibility analysis and other policy decisions related to emerging mobility options.

Following real-world practices, we build analytical models to study two strategies in which the manufacturer leads BT adoption (MLB) and the retailer leads BT adoption (RLB). Our results show that BT adoption does not necessarily create extra supply chain profits. Higher profits can be obtained when consumers show a strong preference for traceability or when the leader shares sufficient costs otherwise. Raising leaders’ cost-sharing proportions does not necessarily benefit followers, and the cost burden may motivate leaders to reduce the traceability level, thereby decreasing overall benefits. Interestingly, cost-sharing is not a “zero-sum” game for supply chain members, and sharing more costs as followers may help create mutual benefits. A comparison of the strategies of MLB and RLB reveals that the product price, traceability level, and carbon emissions in MLB can either be higher or lower than those in RLB. From an environmental perspective, we show that the carbon tax has a nonmonotonic effect on product retail prices. For the supply chain, it is possible to increase profits but simultaneously reduce emissions in each strategy, and a superior strategy that improves both economic and environmental performance exists. By modelling the regulator’s participation in BT adoption, we further show that emission taxes and BT subsidies are not concomitant, and surprisingly, we find that the emission tax may either increase or decrease with product emission intensity. Moreover, our extension shows that regular operational costs for BT may impact the economic performance of BT adoption but other key findings remain robust.</div></div>","PeriodicalId":49418,"journal":{"name":"Transportation Research Part E-Logistics and Transportation Review","volume":null,"pages":null},"PeriodicalIF":8.3,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142312121","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 takes advantage of both networks to realise more accurate prediction of ship trajectories. Furthermore, the performance of the proposed model is comprehensively evaluated using Automatic Identification System (AIS) data from three water areas representing traffic scenarios of different safety concerns. The superiority of the proposed model is verified through comparative analysis with twenty other methods, including the state-of-the-art STP in the literature.

However, the lowest carbon emission is followed by higher travel time and response time. Thus, metamodel-based optimization was also performed via desirability function analysis.

Additionally, these factors have distinct impacts on the supply chain members, which can cause inefficiencies across the entire chain. Our study aims to propose an appropriate contract for fashion chain members by considering the impact of shipment policies (single vs. dual). By comparing the benchmark cases, we first address the policy-level dilemma of a vertically integrated fashion firm. We offer a decision matrix for the optimal shipment policy. This matrix weighs production uncertainty, product obsolescence, and associated holding costs. Using the findings of the benchmark case, we investigate the effectiveness of traditional wholesale price and quantity discount contracts. We find these contracts fail to address issues pertaining to flexibility and equitable risk-sharing mechanisms. Finally, we propose a novel risk-sharing quantity discount contract to address these shortcomings.
