For the multi-contaminants batch water network optimization problem
a mixer-integer nonlinear programming model with the objective of minimum fresh water usage was established. Meanwhile
a solution strategy combined with matrix encoding genetic algorithm and trust region sequential quadratic programming(TRSQP)was proposed. In this paper
the matrix encoding method is easy to establish scheduling module
so the water reused relationship between the water units is more clearly defined.The integer variables was optimized by matrix encoding genetic algorithm and the continuous variables was optimized by TRSQP
the optimal strategy integrated the two methods to achieve the solution of MINLP model with the MATLAB software. The proposed method was used to solve two typical examples and the results obtained were superior to those in literature
which demonstrated that the approach introduced by this paper was effective.
