Hierarchical modelling of objectives
•	Based on the objectives generated in the group part, use Web-HIPRE to create a hierarchical model of the objectives.  
•	Check the set of objectives for redundancy.
•	Include only essential objectives into the hierarchy. 
•	The hierarchy should be minimal.
•	You may also create new objectives.
•	Include also decision alternatives into the model. (They must be the same as in the group model.)
•	Write a brief description of the objectives not presented in the group part if such objectives are included in the hierarchy.
•	Paste the objectives hierarchy into the answer section below. 
•	See the ”Hierarchical modelling of objectives” section at the MCDA web site.
