六標準差是企業用來改善製程、管理製程與產品設計的一項企業策略。因為，六標準差是一種以專案引導 (project-driven)的方法論，在企業界，專案必須優先考慮能為組織提供最大財務利益者。為了要決定六標準差最適合的改善專案之優先順序，我們提出一項為六標準差專案評選 (project selection, PS)的分析架構。由於專案評選是屬於一種多準則決策問題(multiple-criteria decision-making, MCDM)，我們建議運用一種結合決策實驗室分析法(DEMATEL)、網路程序分析法(Analytic Network Process, ANP)以及多準則最佳妥協解法(VIKOR)的混合式多準則決策模式(hybrid MCDM model)來評選六標準差改善專案。印刷薄膜的品質對電子產品與食品包裝極為重要。我們選擇台灣的薄膜印刷產業，作為我們研究六標準差(Six Sigma)專案評選的實證模型，以及分析每一準則之渴望值誤差(aspiration gaps)，期望能達成預定績效水準。

Six Sigma is a business strategy that can be applied to process improvement, process management and product design. Because Six Sigma is a project-driven methodology, the projects that provide the maximum financial benefits to the organization must be prioritized. To evaluate the priorities involved in selecting the optimal improvement projects for Six Sigma, we present an analytical framework for Six Sigma project selection (PS). Because PS is a type of multiple-criteria decision-making (MCDM) problem, we propose a hybrid MCDM model that combines a decision-making trial and evaluation laboratory (DEMATEL) technique with an analytic network process (ANP) and the ‘VIseKriterijumska Optimizacija I Kompromisno Resenje’ (VIKOR, which translates as “Multi-criteria Optimization and Compromise Solution”) method. The quality of printing films is a very important issue for electronics and food product packaging. We selected the film printing industry of Taiwan as an empirical model to study the PS of Six Sigma and to reveal methods of improving the gaps in each criterion to achieve the aspiration levels of performance.
