+## Supply Chain Procurement TCO
+[[Supply Chain Strategist Agent]] 使用 TCO 作为采购决策的核心依据，而非单一比较单价。
+
+### Cost Components in Procurement
+- **直接成本**：单价采购价、工装模具费、包装费、运输费
+- **间接成本**：检验费用、来料不良损失、库存持有成本、管理费用
+- **隐性成本**：供应商切换成本、质量风险成本、交付延误损失、协调开销
+- **全生命周期成本**：使用和维护成本、报废和回收成本、环保合规成本
+
+### Decision Principle
+> "While supplier C's unit price is 5% higher, their incoming defect rate is only 0.1%. Factoring in quality loss costs, their TCO is actually 3% lower." — [[Supply Chain Strategist Agent]]

+- 采购决策必须综合考虑直接成本 + 间接成本 + 隐性成本，而非仅比较单价
+- 关键物料宁可接受更高单价，也要确保供应安全（TCO 中隐含供应中断成本）
