摘要

薄膜電晶體液晶顯示器 (TFT-LCD) 專業製造工廠，以其專業的技術與製程製造能力提供其顧客完善服務，TFT-LCD廠所投資成本比一般傳統性工業甚為可觀，為了符合各樣多變的顧客需求，如短的製造週期與配送時程 (如JIT 及時交貨下，顧客指定交貨日期寬放極短)，與快速顧客回應 (顧客訂單或設計有臨時變動，要快速反應在製造工序上)，高品質，低成本等等需求皆較以往有過之。

CIM (Computer Integration Manufacturing) 系統可以縮短工單工時，提升設備使用率，改善品質及降低成本，且能符合客戶動態需求的必要性；CIM 依照其FC (Factory Coordination)及PAC (Production Activity Control)之架構，加上佐以MES (Manufacturing Execution System) 為FC 及PAC 之介面；由MES整合MRP (Material Requirement Plan)，BOM (Bill of Material)，PDD (Product Definition Database) 資料庫，及歸納彙總整理儲存產品資料收集，提供上位FC及下位PAC製造排程、配工、資源分配、效率、稽核動作；CIM 系統下的MRP 與PDD 處理顧客訂單接單、確認及預定交貨期，並將顧客訂單依照目前產能與資源來排定工廠工單；並能讓一個資本與知識密集的高科技TFT-LCD廠，導入各種自動化設備，製程規劃與控制，生產排程，物料需求與規劃，以及搬運系統予以整合之；從顧客手中接受訂單，確認訂單，排定交期到原料物料請購，再將顧客訂單分割成小批量之生產線工單，工單之製程規劃，排程，執行，直到工單完成再予以整合成原有的客戶訂單等等的製造管理、執行、決策工作皆由CIM 系統來統整執行之。

本篇技術報告主要在探討電腦整合製造系統對薄膜電晶體液晶顯示器製造廠經營績效之影響，報告中首先介紹了CIM 的定義、CIM 系統的效益、TFT-LCD 的製造流程、CIM系統功能架構、以及CIM系統在TFT-LCD產業的應用等相關議題，深入研究導入CIM 系統的個案H公司。

本研究經過分析後發現，CIM 系統在所探討的各個構面中，IBM Poseidon與Consilium WorkStream系統不論於Customization程度和彈性、專案管理、功能層面及整合介面等各功能構面上，各有其優缺點與差異性；但就H公司而言，引用IBM Poseidon系統則無需承擔Consilium WorkStream既有的風險與資訊技術 (IT) 過於老舊日後需汰換之困擾，且IBM Poseidon能完全配合上H公司的Ramp Up的進度與系統穩定度的考驗，進而提升H公司全自動化時的生產力。

Thin Film Transistor - Liquid Crystal Display (TFT-LCD) Manufacturers, with much higher investment cost than other traditional manufacturers, have provided their customers with good services in terms of highly professional production techniques and capacity. In order to meet customers’ various requirements such as shorter manufacturing time, Just in Time Delivery, and high-quality products with lower cost etc., a much more effective system has recently been introduced to TFT-LCD Manufacturers.

This system is so called Computer Integration Manufacturing (CIM). Through enterprise modeling, comparison, with object-oriented method for the CIM model, it becomes a good system for TFT-LCD Manufacturers to solve problems encountered when facing customers’ numerous demands. The manufacturing lots are scheduled and dispatched to the right cell at the right time through the coordination of the scheduler, dispatcher and monitor of FC. First of all, customer’s order is entered into Manufacturing Execution System (MES). Next, the MES is to be integrated with Material Requirement Planning (MRP), Bill of Material (BOM) and Production Definition Database (PDD) to prepare piece parts for the production. Then, customer orders are scheduled as factory orders and released into shop floor control systems. Factory Coordinator (FC) and Production Activity Control (PAC) then take over the factory orders (Jobs). Finally, PAC continues to monitor and follow FC’s schedules to complete the whole production. Through this system, TFT-LCD Manufacturers are able to deliver products to customers with their expected delivery date, quality requirement and other agreements stated on the purchase order.

The major research in this paper is mainly about the impact of CIM system on the operation performance of TFT-LCD manufacturers. The paper discusses the definition of CIM, the benefits of CIM system, the process flow of TFT-LCD, the functional structures of CIM system, and the application of CIM system in TFT-LCD industry, through the case study of Company H.

The analysis and comparison in this study found that the two CIM systems under study, the IBM Poseidon and Consilium WorkStream system each has its own advantages and disadvantages in terms of customization degrees and flexibilities, project management, function levels and interface integration. However, for Company H, the IBM Poseidon system has some other benefits. Applying IBM Poseidon system not only gets rid of the current risks but also avoids the troubles resulting of the information technology (IT) too outdated which may be obsolete in the future from Consilium WorkStream system. At the same time it can catch up with the Ramp up progress, help to maintain the stability of the whole system, and eventually increase the productivity for Company H.
