以失效模式與效應分析 (FMEA) 評估防洪抽水站管理模式之研究

Evaluation of the Flood Pumping Station Management by Using the Failure Mode and Effects Analysis (FMEA) Technigue

指導教授 : 鄭光炎 張寬勇

摘要


有鑑於當前防洪抽水站常見之管理模式有別,計有:(1)鄉鎮市公所執行操作並辦理委外維護保養、(2)鄉鎮市公所執行操作,由縣市政府辦理委外維護保養及(3)縣市政府辦理委外代操作及維護保養等三種管理模式。各個防洪抽水站機組設備之型式、規格及容量互異,人力配置不等,抽水頻率亦不盡相同,在管理模式的作業績效評估上,如沒有統一的比較基礎,難以評定不同管理模式作業績效之優劣。 本研究利用失效模式與效應分析 (Failure Mode and Effects Analysis, FMEA)擬建立一套客觀評量系統,以衡量防洪抽水站於不同管理模式下之作業績效。本研究係以臺灣北部地區三個抽水機組型式相同,但管理模式不同之防洪抽水站為例,從中收集可能導致抽水機能失效的問題點(失效模式)及其關鍵成因,包括耗材損耗、操作方法、機組設備維修及設備本體等,設計FMEA檢核表並建置評量系統,以評量於不同管理模式下各防洪抽水站之作業績效。利用各站最近一年期之例行作業檢查書面紀錄資料,匯入建置完成之評量系統,進行實證分析以獲取本研究之結論。 透過本研究已順利將失效模式與效應分析 (FMEA) 方法導入,針對防洪抽水站管理模式之作業績效建置可量化之評量系統,可針對不同防洪抽水站管理模式之作業績效進行評估,同時利用本研究所建立之FMEA檢核表,可發現各不同抽水站之主要問題點 (失效模式) 發生處,以防範於未然。

並列摘要


There exist different management models in the current flood pumping station practice. The most common three types of management models include: (1) the local township office carries out the operation and the local contractor performs the maintenance, (2) the local township office carries out the operation but the county (or city) government is responsible for the commission of maintenance work and (3) the county (or city) government commissions contractors to perform both operation and maintenance. Furthermore, different pumping stations are equipped with variants of machine set. The specifications and capacities vary station to station. Therefore, the manpower arrangements and pumping frequencies is not possible fit to a standard planning. Without a unified and fair comparison basis, it would be extremely difficult to assess which management model can achieve the best performance in efficiency, cost reduction and manpower management. This thesis employs Failure Mode and Effects Analysis (FMEA) to establish an objective evaluation system, which is able to evaluate the working efficiency of flood pumping stations under different management models. This research investigates three flood pumping stations located in northern Taiwan. They are equipped with the same type of machine set, but operated in three different types of management models aforementioned. We collect the crucial causes that might lead to the pumping failure, i.e., failure mode, design the FMEA control table, and then develop a scoring system to evaluate the working efficiency of each station under different management models. The crucial causes include deterioration of material, operating procedure, equipment maintenance, equipment itself and so on. By means of the routine inspection records of each station through the most recent year as input data for the developed system, conclusions are drawn based on the analyses of these case studies. In this research we have successfully shown how to use Failure Mode and Effects Analysis (FMEA) to quantitatively evaluate the working efficiency of flood pumping stations under different management models. We also effectively differentiate working efficiency resulted from various management models through the established evaluation system. In addition, the use of FMEA control tables is helpful to discover how the failure mode occurred in different pumping stations, by which information the decision of corrective actions can be taken to prevent failure in advance.
