Abstract:	DVD碟片的製造過程中，包含有射出、冷卻、塗佈、烘乾、濺鍍、洗邊、膠合、UV燈照，每一個生產環節對DVD碟片的品質都會造成影響。由於主觀的設計缺陷及客觀的操作環境因素將造成設備或元件的損傷，如機器的磨耗、塑膠的彈性疲勞等等。光碟塗佈機以旋轉的方式運作，其軸承會因為加工公差或裝置定位問題，使得旋轉時產生不平衡振動造成軸承疲勞現象。本文將塗佈轉速作為塗佈機(2,2,1)系統之負荷強度，以量產為目標設計其最佳的負荷轉速分配，再以彩色時間派翠網路模擬(2,2,1)系統的失效行為，根據模擬結果找出適當的系統預防保養維修之週期。 The manufacture of the DVD disc contains some necessary processes, whish are disc molding, cooling, dye coating, drying, sputtering, edge cleaning, bonding, and UV-curing. The quality of products will be affected by every manufacturing process. Because of the defects in designing and the external facts of operation, the equipment or components can be damaged in some aspects, such as mechanical fatigue and abrasion . In the DVD disc manufacturing process, the equipment of dye coating called Spin Coater functions with rotation. Due to the unbalanced rotation, the bearing of Spin Coater will be fatigued. In this thesis, we have two discussions on shared-load (2,2,1) system of Spin Coater : (1) The load and the hazard rate of the Spin Coater. (2) Applying Colored Time Petri Net to simulate the failure of the Spin Coater, and to map out the period of maintenance.
