This report provides documentation for CACIs Executive Aids for Crisis Management. The documentation of these computer decision aids demonstrates the capacities of the aids, which were developed to assist Department of Defense crisis managers by providing them with ready access to the historical records of postwar U.S., Soviet, and Chinese crisis behaviors. These aids were significantly enhanced during FY79 by Updating all data files through the end of calendar 1978 Adding a module containing information on the crises of concern to the Peoples Republic of China from 1949-1978 Adding a section that allows users to directly compare the characteristics, actions, objectives, and problems associated with crises of concern to both the United States and the Soviet Union and Producing an aid component that presents the outcomes of Soviet and American crises from 1966-1978. The data file manipulation characteristics of the aids allow crisis planners to search rapidly for historical precedents and analogies in the course of considering crisis options. In noncrisis periods they can serve as instructional devices for crisis management personnel.
