The background of case study • This thesis collects seven months, November 2004 to May 2005, electrical equipment fault event data from a chemical manufacturing firm, about 3200 jobs being analyzed. • The case study company, an ISO9001 and ISO14000 certificated company, produces polyester fiber. • The company was established in October, 1967, and is a full-processing manufacturer of polyester filament and staple fiber. • In terms of capacity, the case study company is the second largest polyester producer all over the world, and is number one in Taiwan.
Access supports a variety of query types (Access 支援各種查詢功能) • These queries return data from one or more tables and display the results in a result table. • The table is updateable, which means that we can change the data in the table and the changes will be reflected in the underlying tables. • Selected queries can also be used to group rows and calculate sums, counts, averages, and other types of totals for these groups.

Comparisons of all factories maintenance fee with/without CMMS
Evaluate CMMS for Knowledge Management • CMMS can also function on sharing KM maintenance knowledge, which has never been measured by computer before. • The hands-on experience sharing has rapidly enhanced the technician’s ability, resulting in 4 out of 72 workforce being saved. • The cost for cultivating a technician is about NT$68,000/per month; the adoption of CMMS system has saved NT$ 272,000/per month for the case study company.
Apply this CMMS to link MIS of enterprise. We perform maintenance management well. Refer to the following description: 1. Define Maintenance Tasks(定義保養工作) 2. Plan Maintenance Work(計畫保養工作) 3. Update Work Order(更新派工) 4. Get Work Done in a Certain Period(限定完工期限) 5. List of Parts Re-Ordered(庫存備品採購) 6. For Conducting Training(員工訓練)

4.1 Conclusion • The goal of maintenance activity is to provide high quality, low cost maintenance. (達成高品質低成本的目標) • A good maintenance management will definitely reduce productive loss. (可減少生產損失) • Adoption of CMMS enhances the performance of maintenance, inspection, monitoring, inventory, and training, etc. (採用電腦化維修管理可以增強保養執行) • By integrating with Enterprise Resources Planning (ERP) or MIS, we can perform better to maintenance management. (採用電腦化維修管理方便與MIS整合) • CMMS, predictive and maintenance tracking systems are now a necessary in managing and controlling assets, plant and equipment maintenance in modern manufacturing. (採用電腦化維修管理對現代製造業是必須的)
4.2 Directions for Future Researches • Re-manufacture, repair, and exchange services for equipments and reliable parts; repair the third party’s parts (low cost) and evaluate the using validity. (開發對抗品,低價位可靠的備品) • Reduce the associated costs on site management of parts inventories, and increase working time to ensure that users have the right replacement parts. • (降低維修備品成本) • 3. Combine CMMS systems with the existing or planning control systems to increase real-time monitoring capabilities. (結合CMMS增強即時監視能力) • 4. Remote diagnostic services to increase facility uptime and reduce overall labor expenses. (遠端維修減少人力浪費)
4.2 Directions for Future Research 5. Consult professionals and expertise to implement EAM solutions without developing additional in-house expertise. (委外顧問及專家) 6.Establish the predictive maintenance practices, which display more effective than that of breakdown maintenance techniques. (建立預知保養執行) 7. Ensure all HMI will automatically transform to maintenance management database, in order to achieve real-time trusty. (HMI自動轉換到維修管理系統) 8.Maintain Database for data security. (database維護及安全)
