We compare both existing and new formulations by their theoretical properties and by their performance in computational experiments. We present results for different classes of transportation problems with separable\/non-separable, continuous\/lower-semicontinuous non-convex piecewise linear cost functions.\n\u003C\/p\u003E\n\u003Cp\u003EThis is joint work with Prof. Shabbir Ahmed and Prof. George Nemhauser. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Mixed Integer Programming Models for Non-separable Piecewise Linear Cost Functions","format":"limited_html"}],"field_summary_sentence":[{"value":"MIP Models for Non-separable Piecewise Linear Cost Functions"}],"uid":"27187","created_gmt":"2009-10-12 20:37:43","changed_gmt":"2016-10-08 01:47:34","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-10-28T16:00:00-04:00","event_time_end":"2008-10-28T17:00:00-04:00","event_time_end_last":"2008-10-28T17:00:00-04:00","gmt_time_start":"2008-10-28 20:00:00","gmt_time_end":"2008-10-28 21:00:00","gmt_time_end_last":"2008-10-28 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5652","name":"Piecewise linear"}],"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.
