| 摘要: | 在現今電子產業，隨著代工模式的發展，品牌擁有者更加注重保護自己品牌的形象。而製造業者往往被要求提供產品生產過程中所使用物料的資訊，或是提供含有特定物料的產品出貨資訊。製造業者必須提供這種服務，確保與品牌廠商穩固的合作關係。因此物料的可追溯性已然成為是製造業的主要需求，對於缺陷產品招回成本的降低和製造流程的改進具有重要的意義。
本文的研究對象A公司是國內工業電腦製造商，主要生產量測、自動化及電腦通訊科技相關的工業電腦設備，並以自有品牌銷售全球。由於產品銷售遍及全球各地且大多用於精確度要求極高的產業，因此對於產品品質要求相當嚴格，A公司如果無法維持或提昇產品的良率及品質，不僅會影響公司商譽並對業績帶來衝擊，也會讓客戶蒙受損失。而近年來因業務拓展快速，產品線增加及產品客製化程度升高，導致產品用料及製程更為複雜，返修率因此大幅增加。因此為了提昇產品品質，並且滿足外部客戶對於產品用料的查詢要求，A公司希望通過導入物料追溯系統來解決這些問題。
本文根據工業電腦製造業的普遍特點，研究A公司目前在製造過程中造成無法實現物料追溯的根本原因，包含作業流程、物料管理的不足及資訊系統的限制，並基於目前MES系統的結構、作業體系提出生產流程改善及資訊系統規劃，期望目標為完成支持物料追溯的各項功能模組的需求分析、設計與實現。
Nowadays, in the electronic industries, along with the proliferation of the OEM model, brand owners pay more attention to protect their brand image. Hence, material traceability has become a major issue facing manufacturers, who are required by the brand owners to provide these detailed usage information of materials and components in the production process. They must comply to ensure long term relationship. Therefore, traceability provides significant benefit in cost reduction in case of product recalls caused by defectives.
The focus of this study, Company A, is an industrial computer manufacturer, with its own brand with global sales. Its major products include measurement, automation, computer and communication equipment, mostly with high precision and high quality requirements. Company A must constantly improve its yield and quality, to maintain its reputation and relationships with its clients. Recent growths in sales for Company A, coupled with expansion in product lines, increased in customization, lead to more complicated sources of materials and production processes. These have resulted in higher repair rates. In order to improve product quality and fulfill external customer’s needs, company A is faced with immediate requirement for better traceability.
Based on the general characteristics of computer manufacturing, this study identified the causes inhibited material traceability as: lack of proper operating procedures and materials management, and the limitations of the current information system. An improvement plan is proposed, including a reengineered process for material handling, changes in its MES System to include several functional modules. These will hopefully result in a new level of material traceability for Company A. |
