生命周期成本
本帖最後由 hlperng 於 2019-4-21 20:20 編輯
生命週期成本 (life cycle costing, LCC) 亦有翻譯為壽期成本,又稱為總成本會計或總擁有成本 (total cost of ownership)。
- Life cycle costing is the process of economic analysis to assess the total cost of acquisition, ownership and disposal of a product. (ref. IEC 60300-3-3:2005, Introduction)
- Life cycle costing: process of economic analysis to assess the life cycle cost of a product over its life cycle or a portion thereof. (ref. IEC 60300-3-3:2005, 3.2)
Cost = Acquisition cost + Ownership cost + Disposal cost
生命週期成本分析 (life cycle cost analysis, LCCA)
- LCCA is a process of evaluating the economic performance of a item over its entire life.
