Abstract

An expert information system with which a decision maker in the construction, or a related industry, can generate a decision record and related control instructions in a facile manner without significant omissions while ensuring that substantially all of the options available for making the decisions have been considered. The expert system includes a microcomputer which executes a system control program to select information units from the expertise of a data base and to concentrate individual information units until an entire decision record has been generated. The process is enhanced by a multiwindowed display which displays possible selections from the expert data base while contrasting that data with data in another window having a list of data indicating the decisions or selections already made. A display pointer with a controllable position is employed to select lines and phrases of the expert information from that portion of the data base displayed in the selection window. The selection of such informaiton causes the line or phrase from the data base, an information unit, to be transferred to the decision record and to the display of the selected decisions window.
