System for graphically generating the sequence and temporal relationship between tasks in a project

A computer based system for generating graphic charts and textual representations identifying the temporal and sequential relationship between a plurality of tasks which must be performed to complete a project. The system initially receives as input, from the user, a listing of the tasks and their durations. The system then generates and outputs to the user a series of inquiries each relating to the sequential order of at least two of the tasks. By selection of the tasks forming the basis for each inquiry and a logical analysis of the user's responses to previous inquiries, the system logically deduces the sequential order between all of the tasks with a minimum number of inquiries. Using the task list and duration and the sequence order derived from the responses to the inquiries the system then graphically displaying the tasks and their sequence produces any of a variety of charts, including a PERT chart, and other alphanumeric listings useful in planning and accomplishing the project.
