近年來民生經濟未見好轉，各項原物料價格飆漲，其中銅價由92年每公斤57元上漲至今最高每公斤達318元，導致竊賊覬覦偷竊電業高價纜線變賣，造成電業財產及營運等各項損失外，更易因纜線被竊導致配電線路停電，進而影響供電戶用電之權益及造成民眾公共安全之虞慮。故電業為有效抑低纜線失竊率，投入大量經費研究防制對策，以減少因纜線失竊所造成的龐大損失。 本論文研究探討電業在嘉義縣市防制纜線失竊之各項專案效益，應用資料包絡分析法(Data Envelopment Analysis; DEA)分析，其投入變數為各項專案之人事費用及沉沒成本，其產出變數為抑抵數量與減損金額，建構模型以瞭解電業在防制纜線失竊各項專案之執行成效，其分析結果提供電業在推動各項失竊專案管理執行上與編列預算之參考，以較合理之投入成本獲取專案之最大效益，並達到降低纜線失竊率之目的。 In recent years, raw material prices have continued to increase despite the continual decline in economy. Specifically, copper price rose from $NT57 per kg in 2003 to the current $NT318 per kg. This substantial price increase lead to thefts of costly electrical cables for selling, causing not only losses in the properties and operations of electric power industry, but also power outage resulting from thefts of distribution lines, thereby negatively influencing the interests of households to which electricity is delivered and generating public safety concerns. To reduce the rate of electrical cable thefts, electric power industry has invested substantial funds in research projects to seek preventive measures for reducing the considerable losses caused by cable thefts. By using Data Envelopment Analysis (DEA), this study explores the effectiveness of various projects that were aimed at controlling electrical cable thefts in Chiayi County. The input variables include personnel costs and project sunk costs, and the output variables are the number of suppressed attempts and the amount of impairment. A model is established to examine the effectiveness of electrical cable theft prevention projects initiated by the electric power industry. The findings of this study can serve as a reference for executing antitheft projects management and planning budgets, to achieve maximal benefits from dedicated projects to which reasonable investments are made and thereby reduce the rate of cable thefts
