Embedding the gradient direction search and new kinds of evaluation functions into the Genetic Algorithm, a special hybrid Genetic Algorithm with mutation along the weighted gradient direction to solve non-linear programming problems is developed. Then in Chapt 4, a type of nonlinear programming problems with fuzzy objective and fuzzy resources constraints is discussed, in which the objective is ill-defined and the resources possess two different types of fuzzy resources, i. e., tolerance and imprecision. By way of description and formulation of fuzzy objective and fuzzy resources, the problem with fuzzy objective and two different types of fuzzy resources is modelled into a fuzzy nonlinear programming model FO/RNLP and interpreted as three equivalent alternative crisp model to reflect the variety of the environment and the subjective and preference of the decision maker .

本文首先针对遗传算法在求解非线性规划问题中存在的问题，首次提出非可行点／染色体的主导准可行方向，准可行方向，及非可行点属于可行域的可行度等新概念，借助于模糊思想，提出了描述和度量非可行染色体的新方法；通过嵌入非可行染色体的信息于评价函数中，提出了三种新的评价非可行染色体的评价函数；把传统的启发式方法-梯度方向搜索和新的评价函数嵌入到遗传算法中，提出了一种沿加权梯度方向变异的新型混合式遗传算法；第四章针对生产实际中非清晰定义的模糊目标和两种类型的模糊资源，建立了一类连续型模糊目标／资源约束非线性规划问题的模型FO／RNLP。

By comparing and analyzing, it is concluded that for simple and slow slope terrain, the change of wind speed around hill can be truly calculated by some experimental formula such as MSFD calculations. While for cliffy slope and complex terrain experimental formula cant calculate the wind speed truly, it is well to analyze the question by numerical simulation.

通过对比分析可得，对于简单的、坡度较小的地形，山丘周围的风速变化可以较准确的由一些经验公式，例如MSFD理论模型计算得出；而对于坡度较大的以及较复杂的地形，经验公式无法较准确地对风速做出估算，只能借助于数值模拟来分析。

For the differences between stockholders and creditors, unified rules about accounting information disclosure should be enacted by government. In the end, audit committee and external audit should be established to inspect the manager's selection and compliancy of these rules.

由于股东与债权人等不同的利益主体对会计信息存在不同的需求，必须借助于政府的暴力比较优势制定统一的会计信息披露规则，同时引入外部审计与审计委员会制度，监控经营者对统一规则的选择与遵循，以保证信息披露质量。
