The economic, social and environmental sustainability of last-mile logistical operations poses a formidable societal challenge, demanding major organizational changes and technological inventions in transportation, the success of which will critically depend on the availability of appropriate optimization tools.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this thesis, we study two recent innovations in last-mile delivery: i) \u003Cem\u003Eroaming delivery\u003C\/em\u003E systems, where the orders are delivered to the trunk of a customer\u0026rsquo;s cars, as opposed to a static location like home; and ii) dynamic delivery systems, where vehicles deliver goods locally from an origin depot (or, perhaps a small number of origin depots) to customer locations, and the requests for delivery arise during the vehicle operating period, which, if accepted, must be satisfied within a service window (\u003Cem\u003Ee.g., \u003C\/em\u003Emeal delivery) or by the end of the day (\u003Cem\u003Ee.g.,\u003C\/em\u003E same-day delivery).\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWe introduce the \u003Cem\u003Evehicle routing problem with roaming delivery locations\u003C\/em\u003E and the \u003Cem\u003Emeal delivery routing problem\u003C\/em\u003E, to formalize and conduct a systematic study of the essential features of these systems, and then develop heuristics and optimization-based tools that enable their successful deployment. On a more basic level, we contribute to the understanding of the relation between cost and service quality objectives in dynamic delivery systems, through the study of a series of models with a highly simplified geometry, exploring the structure of optimal solutions and providing efficient algorithms to solve some vehicle routing and demand management (order acceptance strategies used when the system is overwhelmed by demand) problems.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Innovations in Last-Mile Delivery Systems"}],"uid":"27707","created_gmt":"2017-12-04 15:48:31","changed_gmt":"2017-12-04 15:48:31","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-12-13T10:30:00-05:00","event_time_end":"2017-12-13T12:30:00-05:00","event_time_end_last":"2017-12-13T12:30:00-05:00","gmt_time_start":"2017-12-13 15:30:00","gmt_time_end":"2017-12-13 17:30:00","gmt_time_end_last":"2017-12-13 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
