基于区间直觉模糊不确定语言的中小企业电子商务网站建设决策方法研究

Research on Decision Making Method of E-Commerce Website Construction of Small and Medium Sized Enterprises Based on Interval Intuitionistic Fuzzy Uncertain Language

阐述中小企业在整个国民经济中的重要地位,指出电子商务对于中小企业具有天然的适应性和可行的推广性.揭示研究对象中蕴含着广泛的模糊性,应用区间直觉模糊不确定语言的必要性.介绍区间直觉模糊不确定语言的基本概念、基本运算、算术平均和加权平均、距离、期望函数、精度函数、期望函数值、精度函数值以及对象比较方法等内容.提出区间直觉模糊不确定语言决策步骤:设定方案集、指标集、专家集,确定评判矩阵,确定指标权重,计算加权平均,计算期望函数、精度函数,期望函数值、精度函数值,进行排序.以盛东商贸有限公司电子商务网站设计方案测评为例,碍出方案3优于方案2优于方案5优于方案1优于方案4的结论.

This article expounds the importance of small and medium enterprises in the national economy, it points out that electronic commerce has a natural adaptability and fea- sible generalization to small and medium-sized enterprises. It reveals that the research object contains a wide range of fuzziness, and the necessity of applying the interval fuzzy uncertain language. This article introduces the basic concepts, basic operation, arithmetic average and weighted average, distance, expectation function, precision function, the expected function value, the precision function value and object comparison method of interval intuitionistic fuzzy uncertain language. This article presents the steps of interval valued intuitionistic fuzzy uncertain linguistic decision making： Set the program set, index set, expert set, determine the evaluation matrix, determine the weight of the index, calculate the weighted average, cal- culate the expectation function, precision function, the expected function value, the precision function value, and then sort. As an example of the design of e-commerce website, this article draws a conclusion that the scheme 3 is better than the scheme 2 and the scheme is better than the scheme 5 and the scheme is better than the scheme 1 and the result is better than the scheme 4.
