光學模組新產品開發因各種開發時產生變異的因素，一個零件的改變可能導致一連串光學設計値之變異，以田口方法為基礎之穩健設計可能得以降低不確定性與變異。然而多數有關穩健設計的研究，均著重在使用統計技術，來解決較小範圍的產品特性或流程最佳化，少有對於變異的識別以及產品特性對雜音變化敏感性進行探討，以及較少對於應用結構化穩健設計方法在新產品開發階段的活動中做討論與研究。

本研究以探討田口方法為基礎之穩健設計應用在光學模組開發流程中，整理出一種結構化穩健設計的產品開發管理流程，對於市場的不確定性、產品與技術的不確定性進行評估流程改善，並藉由個案探討開發一個穩健的光學模組平台，其意義在於可替換不同的機能或零件模組，將模組化平台套用在生產過程以及產品設計當中，達到產品穩健性與多樣化的效果，因此運用田口方法為核心之穩健設計解決光學模組間變異達到新產品開發之效益，並以個案推導來歸結流程改善後的績效表現，進一步創造符合客戶需求之穩健設計之產品。

Due to different causes in the product and process variations of new optical module development, the design changes in one part may lead to variations in a series of optical design target values. The uncertainty and variability may possibly be reduced by using robust design method. However, most robust design studies are focused on statistical technique to solve a small range of product or process features. Few studies discuss how to systematically identify variants and product characteristics sensitive to the noises, also less discuss the application of a structured robust design methods in new optical module development activities.

This study investigated a Taguchi-based robust design methodology in optical modules development process, and sorted out a structural robust design in product development process. Addressing the uncertainties of markets, products and technologies, this study evaluates the process improvement and develops a robust optical module platform to replace the function of different parts or modules. Via a case study of backlight module design, the module platform was applied in the product and process design to achieve robustness in a diverse product designs. The Taguchi-based robust design method was shown to address different types of variations in the backlight module designs to achieve more robust parameter settings, to gain the benefits of module development performance and to better meet the customer’s requirements.
