在傳統的產品生命週期劃分下，產品的品質公差設計與機台途程規劃分別隸屬於設計及生產階段，品質公差設計為考慮產品功能與品質損失成本下之最佳化模式；而機台途程規劃則為最小化生產成本或平衡機台負荷之決策模式。傳統上必先完成設計階段之規劃，生產階段規劃接著必須在滿足設計規格的前提下進行決策。依序規劃下常有：製程能力未能達到公差設計規格、為了達到公差規格導致極高的生產成本、公差規格限制下導致超過機台產能造成瓶頸作業……等等問題，設計與生產未能同步則無法提供真正的最佳化模式。因此本研究嘗試建立一個考慮機台途程之品質公差設計模式，模式中考量生產成本（包括：機台製造成本與機台整備成本）、品質損失成本、重工成本、檢測成本、丟棄成本等成本，並依照需求建構其模式，由於本模式為一個NP-hard混合二元整數規劃問題，本研究並以LINGO 8.0求解，同時達到目標要求與機台產能限制，並探討產品良率、重工與丟棄和總成本之影響，提供製造業者有效率之最小化成本決策模式，做為產品發展設計與生產製造之參考。
