A Fuzzy Expert System for Converting Process Flow Diagrams to Piping and Instrumentation Diagrams

Behnam Baloochy and Ramin Bozorgmehry
Abstract—P&IDs (Piping and instrumentations diagrams) are detailed schematic diagrams of process plants. The production of P&IDs is tedious; involving continual checks of correct connectivity, correct equipment selection, etc. A fuzzy expert system has been developed to aid in PFD to P&ID conversion. The system has been constructed using a set of fuzzy rules based upon individual unit operations. It consists of two main parts: database and application program. The database has been designed using Rational Rose software, and it has been implemented using InterBase. The application program has been designed base on object oriented paradigm and UML standard, and then it has been implemented using Borland C++ Builder compiler. Performance of the developed software has been evaluated base Tennessee Eastman benchmark. This case study shows that the software is capable of handling the PFD to P&ID conversion providing a rich knowledge base.
