Abstract
An input software system is used to provide input to a process simulation software device. The input software system includes an expert system which guides the user step by step through required and optional input to successfully create a flow sheet model. The expert system prevents model overspecification and logically inconsistent specifications. The expert system checks for completeness of the model specification and the reasonableness of parameter values.
