An architecture for active DSS

An architecture is proposed for decision-support systems that can provide active assistance to a user working on complex problems. The major feature is that, in addition to conventional user-directed processes, there are processes directed by a computer-directed-process manager (CDPM). For a CDPM to function, the system must maintain a continually updated model of what the user is doing. The input to this model is a history of the process, gathered by the history-recorder component of the system and analyzed by a history inference processor. Schema theory provides a framework construction of the model of the user problem-solving processes and the CDPM.<>
