The Model of Urban Sewage Treatment under Possibility Measure

Cun- lin LI, Lin ZHANG, Zhi- fu JIA


This paper was investigated the pro blem of urban sewage treatment under the possibility theory. An expected revenue decision model of urban sewage treatment with penalty parameter was established. Based on the possibility measure, the model was transformed into an equivalent nonlinear cons trained optimization model, and the existence of solutions of the model was proved. An example was given to verify the existence of solutions.
