摘要
本文引入模糊数学中贴近度的概念进行环境因素分析,通过一个合理的隶属函数,求出环境状况所对应的模糊子集A_0和各影响因素所对应的模糊子集A_t,然后分别计算A_0和各A_t之间的贴近度,从各贴近度的大小来衡量各影响因素对环境状况影响程度的大小。该方法分析过程简单明了,计算也非常简单,具有较强的实用性。
In this paper, environmental factors is analysed with the concept of approach degree in fuzzy mathematics. Fuzzy sets A_0 and (?)_i, which are correspondding to environmental condition and influence factors respectively can be obtaine with an appropriate subordinate function. Then we can calculate approach degrees between A_0 and A_i and use these to describe the effect level of influence factcrs on environmental condition. This method is very simple in analysis process and calculation. It has a higher practical value.
