This paper first reviews factor reconstructability analysis (RA) modelling completely by data. Gives a description of levelled variable factor reconstruction analysis model generation process and its further extension to forecasting, evaluation and optimisation. It introduces RA modelling with multi‐variety information and knowledge. From generation of mixed variable RA models to generation of models with both data and knowledge, the paper gives a related table and a figure on “Information flow of reconstructability analysis with multi‐variety information and knowledge” which included database, RA relational knowledge base, and interfaces for input of experts' knowledge. Finally, it gives some examples and prospects.
