隨著保健技術與資訊科技的發展與演進，民眾對於保健食品的需求與品質越來越重視。保健食品商需要針對市場的快速且高品質的需求，製造出產品以滿足民眾的需求，然而，各個產品均有多個供應商可以選擇，且各個供應商本身因為製程與技術能力不同，具有不同優缺點，亦沒有單一供應商可滿足所有的需求，此外，隨著近年來保健技術的快速進步與市場需求的增長，保健食品商大約每隔3~6月需推出新產品，在時間與績效的壓力下，選擇供應商為保健食品商所面臨的挑戰。本研究以紫式決策分析架構為基礎，針對保健食品商供應商選擇的問題，提出保健食品供應商選擇決策架構，以選擇產品的合適供應商以共同合作推出符合顧客期待的產品，創造公司營收與提升競爭力。其中，提出的保健食品供應商選擇決策架構，以人、問題、環境的三個維度逐步探討，並以目前實務上保健食品供應商選擇會考慮的因素為基礎，整理出討論的指標與執行步驟。 並建構供應商選擇之根本目標層級與工具目標網路，以良好的顧客關係為總體目標，逐步解構成根本目標，並發展工具目標網路以探討供應商選擇可解決的相關問題。本研究以某一國際保健食品公司為實證研究對象，實際探討供應商選擇問題，以驗證本研究的效度。 With the development and cultivation of health food techniques and information technology, the demand and quality of health food have been emphasized by modern people.
