| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 97 === 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.
