【摘要】 温室的主要能量来源是太阳辐射，确定出最佳的温室前屋面以获得更多的太阳辐射是温室结构设计的关键。本文在承接前人研究理论的基础上，以提高温室的采光量为设计目标，主要以合理时段采光屋面角为依据，并考虑地区纬度、阴天多少、日照百分率高低，应用建立数学物理模型的方法，建立日光温室的采光面模糊优化设计的模型。建模过程中考虑了各个约束条件的模糊约束性，求解过程中应用水平截集将模糊优化问题转化称为普通优化问题。运用Matlab语言为主要数学计算工具，求解数学模型。通过对采光量的计算和分析，证明优化的曲面可以使温室采光量大大增加。更多还原

【Abstract】 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.更多还原
