12 Obiective generale În afară de colaborarea directă, în domeniul ştiinţific, cercetătorii din cadrul centrului nostru îşi propun şi colaborări cu cercetători din străinătate, aceste acorduri având drept scop atingerea unui alt obiectiv strategic al UCB, anume promovarea şi dezvoltarea celor mai bune metode de predare, privind pedagogia universitară şi experienta acumulatăa în alte universitati din străinatate. De asemenea acest obiectiv completează un alt obiectiv strategic al Universităţii Constantin Brâncuşi ce vizează promovarea calităţii în cercetare prin sprijinirea colectivelor care dezvoltă proiecte valorificate prin aplicare directă în spaţiul economic şi social şi prin lucrări publicate/prezentate în reviste recunoscute internaţional (cotate ISI) sau la conferinţe. Este de remarcat aici faptul că membrii centrului, prin publicarea rezultatelor lor ştiinţifice în articole cotate ISI, au atins deja cu succes obiectivul strategic al UCB de mai sus. Obiective strategice Modernizarea managementului cercetării ştiinţifice şi promovarea unui marketing eficient pe piaţa cercetării; Iniţerea unor programe de cercetare în colaborare bilaterală cu universităţi din străinatate şi mai ales din Uniunea Europeană. Încurajarea cercetării ştiinţifice interdisciplinare; Promovarea transferului tehnologic; Elaborarea unor proiecte de cercetare/dezvoltare naţionale sau internaţionale care să permită obţinerea finanţării infrastructurii necesare desfăşurării activităţii centrului. Imbunătaţirea infrastructurii centrului prin achizitionarea unor echipamente şi licenţe software precum şi prin creşterea achiziţiei fondului de carte, de publicaţii periodice şi nu în ultimul rând de abonamente electronice la jurnale de prestigiu. Atragerea studentilor în activitatea de cercetare şi creşterea mobilitătii studentilor şi a personalului academic. Continuarea activităţii în cadrul Centrului a Simpozionului Durabilitate şi fiabilitate Obţinerea cotaţiei CNCSIS superioare pentru revista "Durabilitate şi fiabilitate", jurnal administrat de membrii centrului. Diseminarea rezultatelor obţinute de membrii centrului prin publicarea unor articole în reviste de largă circulaţie internaţională, a unor monografii şi respectiv prin participarea la Conferinte internaţionale importante. Pentru a le face accesibile imediat preprinturile vor fi publicate pe pagina WEB a Universităţii Constantin Brâncuşi. Înfiinţarea şi up-datarea periodică a unei pagini web a centrului. Obţinerea recunoaşterii pe plan naţional şi internaţional a activităţii ştiinţifice a Centrului. 12
