A dynamic planning method for new product development management

Abstract

This article presents a quantifying and reordering method for new product development (NPD) based on concurrent engineering (CE). Herein, we propose to establish a fuzzy design structure matrix (FDSM) which combines fuzzy set theory (FST) and a design structure matrix (DSM). The FDSM can quantify the dependency strength between design activities and reschedule the design process. Utilizing the improved partitioning and tearing algorithms to reorder a FDSM, we can recognize clearly the interdependent relationship within the design activities in the NPD process. The objective of this article is to develop a systematic scheduling method which is efficient and yet flexible for NPD from an informational structure perspective. The FDSM can provide managers with a powerful tool for presenting the structure for the design process. This proposed method can enhance the performance of NPD management including decreasing the activity iterations and reducing the product development time through re-engineering the design process. Eventually, one case study is employed to illustrate the method and the result shows that it can shorten the time and can guarantee the quality and function of the design process.

基於同步工程的概念(concurrent engineering, CE) ， 本文結合了模糊理論(fuzzy set theory, FST) 及設計結構矩陣(design structure matrix)提出了一個模糊設計結構矩陣(fuzzy design structure matrix, FDSM)的動態規劃方法 ； 此方法運用改良的分解(partitioning)及割裂(tearing)算程將設計活動間的關係予以量化及重組以進一步進行新產品開發同步工程最佳化規劃。 本文最主要的目的是要提出一套具效率及彈性的系統性動態規劃方法 ， 此方法可以提昇企業設計開發管理的效能 ， 透過設計過程的重構 ， 經營管理者在面臨新產品設計開發流程規劃時可以減少設計流程的反覆迭代及重工過程 ， 進而縮短設計開發時間以增進產品市場競爭力 ， 最後本文以一個實際的電力線網路橋接器新產品開發流程規劃為例 ， 說明所提出的模糊設計結構矩陣模式(FDSM)之應用方式及其可行性 ； 結果證明此方法確實可以規劃出較佳的同步開發流程以縮短新產品開發時程並能確保設計開發過程的品質。
