    Abstract: This study aims to formulate a decision maker’s (DM’s) risk attitude to modify
    ELECTRE (ELimination Et Choix Traduisant la REalité, or ELimination and Choice
    Expressing REality) III model. We apply both the traditional and modified models to evaluate
    WEEE (Waste Electrical and Electronic Equipment) recycling plants in Taiwan for the
    purpose of improving their operation quality in the future. The results show that both models
    are stable and suitable for the applications of environment evaluation.
    The evaluation criteria include environmental, managerial, social, financial, and
    technological aspects on 15 recycling plants. Taiwan’s Environmental Protection
    Administration (EPA) looks to provide higher differentiated subsidies as a bonus to those
    plants with better performances and offers some directives to the underachieving plants for
    further improvement. We employ concave and convex utility functions to modify the
    concordance and discordance indices in order to represent the DM’s risk attitude, mimicking
    the gain and the loss in the DM’s mind. We also execute sensitivity analyses on different
    weights and thresholds so as to demonstrate the stability of our proposed model.
