The Donaghey College of Engineering and Information Technology (EIT) at UALR offers a graduate program leading to the Ph.D. degree in Engineering Science and Systems (ENSS). The program is designed to provide a collaborative, interdisciplinary framework of graduate studies and research in engineering with exposure to the systems approach that is increasingly the hallmark of current research and development in the global engineering community.The Engineering Science and Systems doctoral program leading to the Ph.D. degree is housed in the Donaghey College of Engineering and Information Technology. Faculty, curriculum, and resources for this program are contributed by six departments: Systems Engineering, Computer Science, Information Science, Engineering Technology, Construction Management and Civil and Construction Engineering, and Earth Science. The program is designed to provide a collaborative, interdisciplinary framework of graduate studies and research in engineering with exposure to the systems approach that is increasingly the hallmark of current research and development in the global engineering community. The program consists of a total of 76 credit hours, which include 14 credit hours of program core courses, 9 credit hours of track core courses, 15 credit hours of electives, and 38 credit hours of dissertation research courses.This track focuses on design and analysis of systems and their architecture, integration of systems, decision and risk analysis, and simulation and optimization of systems, that are part of the technical infrastructure that supports an organization's application and information needs.
