摘要: | 水是人類賴以生存的三大要素之ㄧ,自來水更是國人日常生活中不可或缺的,但由於台灣工商業日益發達,國人生活水準提高,自來水之需求量相對增加。在缺水危機逐年嚴重的台灣地區,因開闢新水源相當不易的情形下,「省水」更顯重要。因此,台灣自來水公司致力辦理逾齡管線汰換工程,預期漏水率可逐年獲得改善。但工程品質乃攸關其是否能有效發揮工程應有之效益與功能,因此台灣自來水公司於總管理處設置「工程督導小組」,並以任務編組方式辦理工程品質督導查驗。在目前工程品質督導人力指派作業,常以人工經驗法則為之,並非最佳化指派,除可能在無形中造成人力指派的不公平性外,並容易造成出差旅費之浪費。 針對上述問題,本研究針對管線工程品質督導人員指派之個別需求及條件,利用LINGO 8.0套裝軟體建立一最佳化人力指派模式,並採用二種不同模式進行分析,除了解決人力資源指派不公平的問題,也藉由不同模式將所求得最經濟成本進行比較與探討。另外依據各參數之敏感度變化趨勢進行敏感度分析,藉由調整各人力資源之限制條件或增減出差旅費配置,以達人力資源公平利用與降低成本的目的。其結果顯示,本研究最佳化模式產生的指派結果,確實較一般人工經驗指派之成本為低且更有效率。因此,本研究可運用於年度預算編列規劃及人力增減檢討等成本規劃問題,提供決策者指派之參考。 關鍵字:工程品質、人力指派、LINGO 8.0、最佳化。 Water is one of the three essential elements that human beings depend on for survival, with running water especially inevitable. Due to the increasing prosperity of Taiwan’s industry and business development and the elevation of domestic living standard, the demand for running water is relatively increasing. With the crisis of serious water shortage, water conservation is critically important, for exploiting new water resources is challenging. Therefore, Taiwan Water Corporation has been always devoted to eliminating outdated pipelines, hoping to improve the water leakage ratio year by year. However, the quality of engineering projects has great impact on whether a project can attain the expected benefit and functions. Consequently, Taiwan Water Corporation establishes a “engineering project supervising team” within the headquarter, and conducts investigation on the quality of engineering projects by task-based grouping. Among the current supervisor assignments for engineering projects, the assignments are often distributed by empirical methods rather than optimal assigning procedure. Therefore, it is more likely to invisibly result in the unfairness of supervisor assignments and tend to cause unnecessary waste during the business trip. To solve the above problems, this study aims to establish an optimal supervisor assignment model by means of LINGO 8.0 software package, which meets the respective needs and conditions for the supervisors assigned to assessing the pipeline engineering project quality. The study also uses two different models to conduct the analysis, in order to manage the unfairness of human resources assignments and to compare and discuss the most economical cost deriving from these two models. Additionally, the study also conducts the sensitivity analysis based on the variation trend of sensitivity for each parameter. By adjusting the human resources constraints or changing the business trip budgets, it expects to obtain the fair distribution of human resources and reduce the capitalized cost. The result shows that the result of the assignment optimization model indicates that it is more efficient and costs less than common empirical assignment methods. As a result, this study can provide the directors with the references of human resources assignments and it can also be applied to annual budget planning and other cost-related issues like the changes in the cost of manpower planning.
