The Study Of Greenhouse Lighting Surface Fuzzy Optimization Design

The main energy source of greenhouse is solar radiation. Defining optimum lighting surface of the greenhouse is the key of greenhouse structural design of greenhouse.In this paper carrying on the senior person's research theory, take the increasing of greenhouse lighting quantity as the objective function, take rational angle of lighting surface as basis and think of over geographical latitude,cloudy day how many and sunshine percentage height, apply the way of establishing mathematics model, establish fuzzy optimization model of greenhouse lighting surface. Through the fuzzy mathematical method used, the fuzzy optimization problem is transfered into the solver of common optimization problem. Matlab is the main mathematical calculating tool of the optimization problem.Though calculating lighting quantity, prove that lighting quantity of optimum lighting surface increase.
