An interval-valued fuzzy-stochastic programming approach and its application to municipal solid waste management

In this study, an interval-valued fuzzy-stochastic programming (IVFSP) approach is developed for municipal solid waste (MSW) management under uncertainty. IVFSP can tackle multiple uncertainties presented as intervals as well as possibilistic and probabilistic distributions. The adoption of interval-valued fuzzy sets is capable of reflecting waste managers’ confidence levels over subjective judgments, and can thus enhance the system robustness. …
