The paper enquires into the applicability of the optimum linear plan method to masterplan for land utilization.

At last,Based on linear programming model,optimal decision of different grading protection area of cultivated land is advanced.

Study on the optimal planning of water resource utilization—a priority discharge model;

With an aim at the existing problems in the optimal planning of water pollution control system, the paper suggests that genetic algorithm (GA) is employed to solve the area optimum planning model.

Multistage transmission network optimal planning (MTNOP) is a complex nonlinear combinatorial optimization problem, which cannot be well solved by traditional optimization methods.

The more-for-less paradox in the optimum programming model about utilization of water resources was discussed.

Using the principle of analytic hierarchy process,the method of optimum programming for sites of thermal power plants is proposed It utilizes the qualitative and quantitative method, and overcomes the difficulties of many qualitative factors,many targes and large searching space.
