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.

A method of forming an input file for a computer controlled model process simulation device, comprising the steps of: displaying on a video display, controlled by computer means, an ordered series of screen views to provide an arranged course for user entry of data for forming a complete input file, at least one screen view providing input fields for receiving data entered by the user through an input device coupled to the computer means; providing to a user on each screen view a state of completeness and prompts directing the user through the arranged course; determining correctness of data currently entered by the user for one input field according to data which was entered by the user for other input fields, and if correct, updating the state of completeness provided by each screen view, a complete state being established when a complete and error free input file is formable from the user entered data, amount of user entered data to form a complete input file being a function of content of data entered by the user along the arranged course; forming a changeable subset of the ordered series of screen views in response to the updating of the state of completeness, the subset providing that portion of the arranged course for user entry of data necessary to enable a complete input file to be formed with data entered by the user thus far; displaying the subset upon user command; updating the state of completeness with each user entry of data in a screen view of the subset; and changing the subset in response to each updating of the state of completeness.
