This is an updated version of an article by the same name that appeared in ORSA CSTS Newsletter, 15:1 (Spring 1994). It surveys recent research and research opportunities in structured modeling. After first reviewing the basics of structured modeling, we discuss improved modeling languages, approaches to model integration, extensions designed for simulation modeling, and three topics falling under implementation strategies and technologies, namely host software, language-directed editors, and language-based customization of specialized application packages. In addition to describing completed work and work in progress in these areas, we highlight numerous attractive research opportunities.
