Study on water treatment system's optimal operation model and its solution method

According to the popular water treatment process of waterworks in north China, a nonlinear mathematical model with multi-objectives and complex constraints is put forward for water treatment system's optimal operation, which is able to minimize the operation costs and give consideration to the safety and tradition. Then LINGO is used successfully to solve the model against its features. Furthermore, the research on the interface between LINGO and the popular office software is made emphatically, which produces a set of optimization software that has LINGO as the core of computation. Through practice, this software is found stable, easy to use and suitable for the application to the water supply corporations.
