The inventory tailing-off effect is counterbalanced by an approximate value function obtained via sampling and data fitting. We also study the fundamental question of whether approximate value functions allow us to shorten planning horizons so that solving multi-period problems becomes computationally tractable.\n\u003C\/p\u003E\n\u003Cp\u003EThis is joint work with George Nemhauser and Martin Savelsbergh.\n\u003C\/p\u003E\n\u003Cp\u003EThis is a joint SCL\/DOS Seminar. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Decomposition of Multi-Period Inventory Routing Problems Via ADP","format":"limited_html"}],"field_summary_sentence":[{"value":"Decomposition of Multi-Period Inventory Routing Problems Via ADP"}],"uid":"27187","created_gmt":"2009-10-12 20:36:10","changed_gmt":"2016-10-08 01:47:09","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2009-03-27T12:30:00-04:00","event_time_end":"2009-03-27T13:30:00-04:00","event_time_end_last":"2009-03-27T13:30:00-04:00","gmt_time_start":"2009-03-27 16:30:00","gmt_time_end":"2009-03-27 17:30:00","gmt_time_end_last":"2009-03-27 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5311","name":"multi-period"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EAnita  Race\u003C\/strong\u003E\u003Cbr \/\u003EH.
