| Abstract: | A program for a visual display computer is described which enables a user to ‘draw’ pictures closely resembling chemical plant flowsheets. It is thought that this approach could be useful as a means of introducing the problem structure into the computer and also as a visual aid for the user. Specifications are described which were laid down for this new program and which were formulated as a result of experience gained with a previous more general network drawing program. An account is given of the major problems which arose in the implementation and the solutions which were adopted. |
