Even though the probabilities are small, rare events can be important. Rare events might correspond to queue lengths exploding or buffers overflowing in a manufacturing system. Even though these \u0022large deviations\u0022 are rare, it can be important to know just how rare.\u003C\/p\u003E\u003Cp\u003EConsider a system that can be modelled as a Markov process and has a stationary distribution that cannot be computed explicitly. We are developing methods for deriving exact asymptotic expressions of the stationary distribution. Furthermore, the methodology gives insight into how various large deviations develop, which allows system designers to know how to improve the system.\u003C\/p\u003E\u003Cp\u003EDuring the seminar, I will illustrate the methodology by analyzing a particular queueing system. I will also point out how some of the ideas in this research can be used in rare event simulation.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"APS Seminar"}],"uid":"27187","created_gmt":"2012-04-17 09:54:32","changed_gmt":"2016-10-08 01:58:45","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-04-20T17:00:00-04:00","event_time_end":"2012-04-20T18:00:00-04:00","event_time_end_last":"2012-04-20T18:00:00-04:00","gmt_time_start":"2012-04-20 21:00:00","gmt_time_end":"2012-04-20 22:00:00","gmt_time_end_last":"2012-04-20 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[],"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":"\u003Cp\u003EDave Goldberg \u003Ca class=\u0022moz-txt-link-rfc2396E\u0022 href=\u0022mailto:dgoldberg9@isye.gatech.edu\u0022\u003E\u0026lt;dgoldberg9@isye.gatech.edu\u0026gt;\u003C\/a\u003E email or by calling: (201) 723-4314.\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
