Abstract
This paper develops a framework to differentiate welding processes, for industrial purposes, according to two families of criteria. It is constructed as a phase-wise decision support system that reviews objects with physical and economic criteria. The first phase excludes the non-functioning processes from the panel, and catching the best candidate processes are left to the second phase. The second phase is an integrated mechanism that weights the active criteria versus the goal using a FUZZY-AHP system and then it ranks the candidates using a FUZZY-TOPSIS system. Both phases operate linked with parallel and accessible database and knowledge-base to accommodate a large variety of welding factors (alternative welding processes and welding criteria) and allow inserting new ones. This framework is mechanized as a portable software, and then validated based on existing cases. The proposed framework is advantageous with having a flexible opened structure that can manage existing and expected industrial problems.
