As declared by the EURO Council, the main purpose of the EWG's is to encourage communication and research between small groups of members specializing in particular topics.

Fuzzy logic and fuzzy set theory have several important connections with Operations Research (OR), for instance, in the fields of mathematical programming, preference modelling and its applications in multicriteria decision aid, scheduling, representation and exploitation of non-stochastic types of uncertainty, etc. The purpose of EUROFUSE is to communicate and to promote knowledge of the theory of fuzzy sets and related areas and their applications.

It is a general principle of EURO that EWG's should bring together people with different backgrounds (like industry, university, etc) who are interested in the same OR topic in order to exchange ideas, experiences and research results. EWG's are free in planning special activities in accordance with the Charter for EWG's.
