301型電聯車集電靴碳刷同等品成本之研究

本研究係以高運量301型電聯車集電靴碳刷為例，以原廠品與非原廠品兩種型式之電聯車集電靴碳刷作分析比較，另以中運量VAL256電聯車集電靴碳刷相關採購及分析資料做參考，評估各廠商集電靴碳刷之特性，進而探討同等品採購及降低本成之關聯。經資料統計發現，原廠品使用壽命、平均磨耗率、年耗用金額均優於非原廠品，故考量集電靴屬性特殊，欲開發同等品，除須提供足夠之測試數量、長時間測試、耗費人力外，其所衍生之風險亦高，所以建議爾後檢討購料成本時，再另行評估開發同等品之適切性。

In this study, the comparisons and analyses of the costs of original and non-original current collector brushes installed in 301 rolling stocks are presented. The relevant procurement and analytical data of current collector brushes installed in medium-capacity VAL256 EMU cars are also introduced for reference to evaluate the features of different products. Further, the relevance between equivalent product procurement and cost down is discussed according to the information statistics. Results show that the expired duration, average abrasion rate, yearly consumption amount of the products from original manufacturers are indeed superior to those of substitutions. Therefore, considering special attributes and high-risk acquisition of the current collector brushes, it is strongly suggested that the feasibility of developing substitutions should be evaluated discreetly through the review of manpower consumption as well as long-term tests.
