Formalizing an Integrated Multidisciplinary Decision-Making Methodology for Ranking Sustainable Infrastructure Designs

摘要

The sustainable success of public infrastructure projects is becoming a driving force of the advancing urbanization boom in developing countries globally. Making informative decisions from sustainable infrastructure designs has been drawing considerable attention in the research community of infrastructure sustainability (IS). However, integrating knowledge of decisionmakers (DMs), who are multidisciplinary professionals with over differentiated expertise, encounter uncertainties in representing decision information due to their various preferences. This study, therefore, has developed an integrated multidisciplinary decision-making (MDM) methodology leveraged by a five-step modeling technique for ranking analysis of sustainable infrastructure design alternatives. It comparatively combines different preferences of multidisciplinary DMs in representing decision information among intuitionistic fuzzy, linguistic, and mixed decision environments. The integrated MDM methodology is then validated by an illustrative example, which is assumed to simulate the collaborative ranking analysis for sustainable infrastructure designs. The validation findings demonstrate the capability of this proposed integrated MDM methodology in deriving objective and consistent ranking results in a multidisciplinary group level of detail. This research contributes to a reasoning methodology of managing representation uncertainties of decision information from multidisciplinary DMs with various preferences for sustainable infrastructure developments.
