Concept of improvement of product considering the qualitative-ecological interactions and weights of attributes

important to support these actions. Mostly, that still remains a
problem in determining precisely the product criteria expected by
customers. In this area, there is a need to identify the customer criteria
and then process them into product criteria. In addition, it is important
to include the environmental aspect so that the customer is satisfied
with the landscape of the product. Therefore, the purpose was to
develop a concept for product quality assessment that considers
criteria relations. This concept will be created based on qualitativeecological interactions and will also include the weights of product
criteria. The proposed conception relies on combined instruments, for
instance, the SMART(-ER) method, a questionnaire with comparison
in pair method, AHP method, DAMATEL method, Likert scale,
WPM method, and relative state scale. The idea is to support an
expert in assessing any product that will be selected by an individual
customer. The originality of the concept allows the identification of
key technical product criteria correlated with customer expectations
for utility and aesthetic criteria.
