Computer Aided Drawing of Process Flowsheets. Final Report, 15 August 1979-15 July 1980

摘要

This project is concerned with the development of a computer program package that automates the lay-out drawing of process flowsheets. Given a list of the equipment items in the flowsheet, their symbol codes, stream connection topology, and aggregation of items into process sections the methodology will deduce the location of the equipment symbols in the drawing space, will lay-out the streams connecting these symbols, will position all peripheral flowsheet symbols and information, and will produce a data file to be executed by a graphics device. All technical work in the project is completed and documentation of the resulting computer programs have been prepared. The program package which has been developed consists of two stand-alone programs: PFL-II, the equipment lay-out logic and PFD-II the stream lay-out flowsheet drawing portion. The former uses concepts and techniques from graph planarity testing methodology; the latter uses novel path structure classification methods. (ERA citation 07:047622)
