      • Selecting a problem model

        Model selection criteria: 

        1. If it is clear what conditions should be obtained in the conflict zone, choose the “Conditions in OZ” model; 
        2. If the condition is formulated as an action, choose the “Actions in OZ” model;
        3. If a technical contradiction is formulated, choose the “TC” model;
        4. If a physical contradiction is already formulated, choose the “PhC” model.
