Uncertain and fuzzy planning for water pollution control of south Feihe river
Based on the best planning of discharge outlet,the interval range values of water environment operating parameters were introduced,two groups of cost and constriction equations were built up,and then the inexact fuzzy linear programming of river water system was established with the fuzzy factors being introduced in the constraint equations.Using this model,the inexact fuzzy programming of water pollution control over the south Feihe river in the city of Hefei is carried out,optimum interval solutions to the treatment coefficient and the expense of various sewage outlets are obtained.The results are comparatively accurate and stretchy,which may be helpful to the water quality planning for the south Feihe river.
