ABSTRACT
Although the analytical hierarchy process (AHP) is a sophisticated multiple criteria decision making (MCDM) tool with a well-defined comparison scale, it is often criticized for its inability to consider the vagueness and uncertainty of judgments of the decision maker. Fuzzy logic is often incorporated into the pairwise comparison process to address the abovementioned deficiency of AHP, referred to as fuzzy AHP (FAHP). FAHP is one of the most widely used MCDM techniques to deal with the high level of uncertainty associated with environmentally conscious manufacturing and product recovery (ECMPRO)-related problems. This chapter presents a FAHP-based model that evaluates and ranks in order alternative product recovery facilities (PRFs). Kuo and team developed an environmentally conscious design methodology by integrating AHP and fuzzy multiattribute decision making. In Li et al AHP and fuzzy logic were integrated to develop an optimal modular formulation for modular product design considering environmental issues.
