Baranovskiy Evgeniy Issledovanie Zadach Optimizatsii


V poslednie desyatiletiya intensivno razvivayutsya napravleniya, svyazannye s izucheniem zadach upravleniya i optimizatsii v sistemakh, opisyvaemykh nelineynymidifferentsial'nymi (obyknovennymi i s chastnymiproizvodnymi) uravneniyami. Odnako pri issledovanii mnogikh zadach teorii upravleniya sushchestvuyushchie metody okazyvayutsya nedostatochnymi. Takaya situatsiya kharakterna dlya upravlyaemykh sistem so slozhnoy strukturoy mnozhestva dopustimykh upravleniy i sistem, v kotorykh neobkhodim uchet obratnoy svyazi. Odin iz sposobov preodoleniya voznikayushchikh trudnostey zaklyuchaetsya v ispol'zovanii metodov teorii topologicheskoy stepeni. Predlagaemaya monografiya posvyashchena postroeniyu novoy topologicheskoy kharakteristiki - stepeni mnogoznachnykh vozmushcheniy odnogo klassa monotonnykh operatorov. S pomoshch'yu etoy kharakteristiki izuchen ryad zadach upravleniya s obratnoy svyaz'yu. V chastnosti, issledovan klass upravlyaemykh sistem parabolicheskogo tipa s asferichnymi mnozhestvami dopustimykh upravleniy,rassmotrena zadacha optimal'nogo upravleniyatemperaturoy v odnoy modeli nagrevaniya sploshnoy sredy s pomoshch'yu neskol'kikh raspredeliteley tepla,issledovana zadacha upravleniya vneshnimi nagruzkami vmodeli L.M.

Matveev Evgeniy Kvantil.naya Optimizatsiya


Poisk resheniya v prakticheskikh zadachakh chasto prikhoditsya vesti v sluchae, kogda nekotorye iskhodnye dannye ne yavlyayutsya determinirovannymi, a opredelyayutsya sluchaynymi parametrami. Pri determinirovannom podkhode k modelirovaniyu sistem vliyanie sluchaynykh faktorov ne uchityvaetsya. No s prakticheskoy tochki zreniya v etom sluchae mozhet byt' poteryan realizm prisutstvuyushchikh v zadache yavleniy. Estestvennyy, na pervyy vzglyad, put' analiza stokhasticheskikh sistem (zamena sluchaynykh parametrov ikh srednimi znacheniyami i nakhozhdenie optimal'nykh upravleniy poluchennykh determinirovannykh zadach) ne vsegda opravdan i mozhet narushit' adekvatnost' modeli izuchaemogo yavleniya. V kachestve razumnogo kriteriya, po kotoromu proizvoditsya optimizatsiya, yavlyaetsya funktsiya kvantili. Funktsiya kvantili kharakterizuet garantirovannyy pri zadannom urovne veroyatnosti rezul'tat prinimaemogo resheniya. Pri takom podkhode maloveroyatnye, naikhudshie sochetaniya parametrov isklyuchayutsya iz rassmotreniya za schyet togo, chto risk ikh poyavleniya ogranichivaetsya na nekotorom dopustimom urovne.
