This paper considers the routing of commodities in a transportation network that is flexible in response to demand through changes to regional warehouse clustering and the designation of consolidation locations. Traditionally, warehouse clustering and consolidation locations are determined as part of strategic planning that is performed months to years in advance of operations—limiting the flexibility in transportation networks to respond to changes in demand. A mathematical programming-based algorithmic framework is proposed to integrate the strategic decisions of location planning with tactical decisions of vehicle routing and synchronisation. A multi-armed bandit problem is developed to explore warehouse clustering decisions and exploit those that lead to small transportation costs. An extensive computational study will show that the proposed algorithmic framework effectively integrates strategic and tactical planning decisions to reduce the overall transportation costs.</p></div>","PeriodicalId":45871,"journal":{"name":"EURO Journal on Transportation and Logistics","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2192437622000164/pdfft?md5=b682e3c823f0fbae488b2759a763d7fe&pid=1-s2.0-S2192437622000164-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130342988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the driving forces of this research is the stagnation in the aviation industry, along with the cessation of all international flights to prevent worse pandemic conditions. The main contribution of the study is clarifying the effect of fleet variety and its financial inferences about fleet standardization and crisis management relationship under inoperative service considerations. Data Envelopment Analysis (DEA) is used as a complementary method for standardization index calculations. According to the results, while the positive contribution of the fleet standardization index to operational revenues was observed, there was no sign of the effects of fleet standardization on the accounting performance of companies. Besides, fleet standardization enabled us to measure the response of Low-Cost Carrier (LCC) and Full-Service Carrier (FSC) airlines in crises. In this study, nine airline companies were selected from both trend representatives, and the results were presented for the U.S. It is found that fleet standardization is related to the adopted flight network type and profitability of each company directly. Results obtained revealed the relationship between fleet standardization and financial relations under inoperative conditions positively. In addition, inferences were made about the effects of the operational policies adopted by the companies.</p></div>","PeriodicalId":45871,"journal":{"name":"EURO Journal on Transportation and Logistics","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2192437622000139/pdfft?md5=0db9fb18bcf0dcdd92663eaa2cc52097&pid=1-s2.0-S2192437622000139-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43674742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models previously designed to schedule truck drivers with interdependent routes have been capable of capturing such scenarios. However, until now, there has been no efficient way to schedule drivers when facing multiple types of interdependency constraints. To overcome this challenge, we introduce properties of truck driver schedules under working time constraints for single-day journeys. A two-stage algorithm exploits these properties to quickly produce schedules for a large number of truck routes. The algorithm minimizes the latest completion time of multiple truck schedules while ensuring that all drivers can complete their route with sufficient recovery periods and within their working hours.

Previous works demonstrated that the maximum performance achievable by traffic control policies depends on the number and location of controllers employed, which implies the need to determine a set of controllers capable of fully controlling the underlying transportation network. Various approaches have been explored in the literature to locate controllers on networks, however a gap remains in terms of scalability as the methods proposed often exhibit heavy computational complexity. In this paper we aim to propose an approach capable of locating pricing controllers on transportation networks that is scalable, such that it can be applied on large instances, such as city-sized or regional networks. For this purpose, we propose a topology-based approach, adapted from the sensor location problem, as both problems share similar characteristics. We validate our proposed approach by analyzing the performance of controller sets produced on a wide range of artificially generated network ensembles. The analysis we provide reveals that the method proposed, while being easily applicable on large instances, is capable to locate an efficient controller set, and to redirect flows on the network so as to reduce the total time spent by road users.</p></div>","PeriodicalId":45871,"journal":{"name":"EURO Journal on Transportation and Logistics","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2192437622000061/pdfft?md5=6eb81aa2e633f03d4a2cdb26a1dc8d5e&pid=1-s2.0-S2192437622000061-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91750800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
