摘要

現今的無線射頻通訊 (Radio Frequency, RF)產業，由於電腦網路通訊、手機行動通訊、衛星通訊以及數位家庭等無線通訊產品日漸普及，市場規模與商機越來越大，使這個產業變成了兵家必爭之地，競爭激烈程度前所未有。為了提升競爭力，各廠家在產品設計上不論機能、外觀及使用材質都不斷地推陳出新，製造上更要追求品質強化服務，提升效率避免犯錯，才能適者生存下來。
本論文運用資訊科技與企業流程改善手法來解決生產現場問題。在個案公司的表面黏著技術 (Surface Mount Technology, SMT) 製程中，嘗試以自行開發的系統解決該製程作業員放錯料件的問題，而在測試製程的用錯程式問題上，則採用自行研擬的企業流程改善手法，先以地毯式檢視整個工作流程細節，找出問題發生的流程步驟確認出需要改善的部分，並運用QC七大手法幫助分析思考問題的原因，再針對原因去找出對策，最後藉由資訊科技運用，重新設計工作流程。
本研究以個案公司生產改善為例，藉由文獻探討、個案公司介紹及其運用自行研擬的企業流程改善手法與資訊科技的案例等面向作探討，獲得以下結論：(1)資訊科技運用，對症下藥比較有效、(2)落實執行，才能實際發揮資訊科技的功效、(3)流程改善手法與資訊科技相輔相成，可以有效改善生產現場問題。

Today’s wireless communication(Radio Frequency, RF) related products such as portable computer, mobile phone, satellite and digital home products become more and more popular, it makes the market size and business opportunities more growing, and competitive than ever. In order to enhance the competitiveness, manufacturers not only continue to introduce new product function, appearance and materials used in product design, but also to pursue quality, enhance service, improve efficiency and avoid the mistakes in manufacturing to survive.
This thesis used information technology and business process improvement techniques to solve the problem of the shop floor. In the case of Surface Mount Technology(SMT) process, the company tried to solve the wrong parts problem with her self-developed system. In another case of using wrong program problem in the testing process, the case company used self-developed business process improvement techniques to review every step of the workflow in detail and identified the steps in which the problems occurred, analyzed the root cause with the tool of Quality Control, then looked for solutions for the problems and by use of information technology to redesign the workflow eventually.
This research takes a case study on a manufacturing company’s improvement of shop floor. With literature review, introduction to the manufacturing company, the case study focuses on how the manufacturing company use the self-developed business process improvement techniques and information technology. There are three conclusions in this research, including : (1)In using Information Technology to improve factory operation, the key to success is to hit the point of business need (2)Good discipline in using Information Technology is required to get the operation done efficiently (3)Information Technology enables process redesign and allows the organization to do production improvement more efficiently.
