本文关注于电子商务网站的产品比价,基于网上商品诸多不确定因素的存在,提出了采用Vague集理论研究比价产品的思想.论文以电子机票为例,借助Vague值表示机票的报价及其可信度,基于用户对产品的需求,通过合理假设,构架了不同航段的比较向量矩阵.最后利用特征值和特征向量求解的方法,得到了满意的机票价格排序,这一方法的引入为电子商务中的产品比价提供了一种新的思路.
In this paper, we focus on the product parity of e-commerce websites, and based on the existence of many uncertain factors in online commerce, this paper puts forward the idea of using Vague Set theory to study parity products.In this paper, taking electronic ticket as an example, Based on the user’s demand for the product, through reasonable assumptions, a comparative vector matrix of different segments is constructed.Finally, the satisfactory ranking of air ticket prices is obtained by using the eigenvalues and eigenvectors, and the introduction of this method is e-commerce In the product parity provides a new way of thinking.
