摘要:	T 公司基於公司政策「人命為首要，工安最優先，落實安衛三化，確保人員及作業安全追求工安零災害之目標，並建構安全、健康、友善之職場環境」的理念，對於職業安全衛生之要求與實施上不乏餘力，每年於年底時訂定明年之「職業安全衛生查核計畫」，其規範了查核計畫之實施與執行相關內容，希望藉由工作現場查核之機制，查核現場之不安全環境、機具、設備、作業程序與人員不安全之行為等危害因素，期能增加工作場所之安全與降低職災發生率。該公司於每年訂定「職業安全衛生查核計畫」時，規劃人員均須依公司現行查核模式，考量查核人員之人數、職級與專業背景等因素進行規劃編組。但近 20 年來公司因配合政府實施用人精簡、遇缺不補等政策，員額精簡達 17.25%，且目前公司面臨人力老化、退休潮來臨，導致基層人力缺額嚴重與人員調動頻繁等現象，本研究應用最佳化理論進行查核人員編組作業，考量相關限制條件，使用 LINGO 12.0 版數學規劃套裝軟體及 Microsoft Excel 2007 版試算表軟體程式建構數學模式，試以相對限制條件下以基層人員指派次數最小值為目標，期能減輕基層人員工作負荷，並達到人員指派公平合理的目的。為了評估本研究模式之實用性，遂進行範例模擬測試與評估分析，測試分析結果甚佳。本研究模式與人工經驗編組模式進行比較分析，發現本研究具較佳之效益，且能大量節省規劃編組人員作業之時間與提升工作效率，並有效改善人工編組作業之缺點。本研究進行敏感度分析，可得知其重要參數之敏感度，於其參數增減情況下對本研究模式之影響並可做為決策者進行查核人員指派之參考。;The company policy of the T Company focuses on the concept of “human life first, work safety priority, and practicing health and safety protocols to achieve the objective of zero personnel and operation safety disaster while building a safe, healthy, and friendly work environment.” The T Company has spared no efforts in meeting the occupational safety and health requirements. It has formulated the "Occupational Health and Safety Inspection Plan" at the end of each year for the following year to regulate the inspection plan execution and implementation related contents in hopes that the on site inspection mechanism can identify the risk factors such as the unsafe environments, machines, equipment, operation procedures, and personnel practices in the workplace in order to strengthen safety and reduce the occupational disaster rate. When the company formulated the "Occupational Health and Safety Inspection Plan" each year, the planning personnel must organize an inspection team according to factors such as the number of inspectors, ranks, and professional backgrounds. However, the company has collaborated with the government to implement the personnel streamlining policy for the past two decades by not filling the vacant job positions, and the policy resulted in a 17.25% staff reduction. At present, the company is facing an aging and retirement trend that is leading to the severe shortage of the base level staffs and the frequent personnel shift phenomenon. In this study, we adopted the optimization theory to perform the inspection team planning operation, considered the relevant restriction conditions, and used the LINGO 12.0 mathematical planning package software and the Microsoft Excel 2007 spreadsheet software program to construct a mathematical model to strive to identify the minimum number of base level personnel assignments under the relative conditions. The goal was to reduce the workload of the base level personnel while achieving the fair and reasonable personnel assignment objective. We performed model simulation tests and evaluation analyses to evaluate the practicability of the model of this study, and yielded excellent test results. We performed comparative analyses between the model of this study and the manual team planning model, and found that the model of this study has better benefits, can save a significant amount of operation time and improve III work efficiency during personnel planning, and can effectively improve the shortcomings of the manual team planning operations. We performed a sensitivity analysis to identify the sensitivity of the key parameters and how the increase or decrease of these parameters can affect the model of this study. The result can serve as a reference for the decision makers when they designate the inspectors.
