因為現今電子商務帶給消費者便利又多樣性的購物管道，所以消費者對於商品 的性能更顯得特別注重，且Weibull分配常應用於可靠度、生存分析、工業工程等等 領域的商品之品質特性。因此，在兩商品的品質特性X 和Y 分別服從具有不同位置 參數的新型Weibull分配且互相獨立之下，我們將運用兩商品之樣本資料藉由性能測 度R(= P[X > Y])之假設檢定來探討兩商品的優、劣。

Because today's e-commerce gives to consumers convenience and diversity of shopping channels, so the performance of goods is particularly special attention for consumers and Weibull distribution often used to quality characters of products in the areas of reliability, survival analysis, industrial engineering, etc.. Hence, under the new type Weibull distribution with different location parameters and independent of each other, we will use the sample data of quality characters X and Y for the two products to explore the superiority and inferiority for two products based on the hypothesis testing of the measure of performance R(= P[X > Y]) .
