Abstract
A two-phase decision support framework is presented and experimented with a case study to find the level of preference of any number of welding processes under a variety of welding circumstances. First phase fathoms unapplied/inappropriate welding processes based on a set of exclusion criteria. Second phase decides the best welding process amongst those remaining according to a set of selection criteria. The second phase is an integration of two methods, FUZZY-AHP which weights the selection criteria with the goal, and FUZZY-TOPSIS which ranks such criteria and gets most suitable welding process. The proposed framework covers a wider range of practical welding criteria with more flexibility and amenability; thus, making it possible to be simply applied in the complex industrial problem.
