《GB/T 41353-2022再制造 机械产品寿命周期费用分析导则》由TC337（全国绿色制造技术标准化技术委员会）归口，TC337SC1（全国绿色制造技术标准化技术委员会再制造分会）执行，主管部门为国家标准化管理委员会。
Introduction
System framework and core essentials analysis
The standard constructs a full life cycle cost model covering the recovery of remanufactured blanks to the final disposal of products, innovatively establishes a three-level cost analysis system for the production stage (18.4%-32.7%), the use stage (51.2%-65.3%), and the retirement stage (8.9%-15.6%), and proposes a dual accounting mechanism of economic cost attenuation function and environmental impact conversion coefficient.
Essence of cost analysis process
| Stage | Input factors | Cost drivers | Confidence interval |
|---|---|---|---|
| Production preparation | CNC equipment accuracy ≥0.01mm | Process plan difference 8-12 times | ±5.8% |
| Mass production | Finished product rate 82%-96% | Reverse logistics cost accounts for 18% | ±7.2% |
Key technologies of cost accounting
- Investment in infrastructure such as three-level cost breakdown structure (CBS) and industry benchmark database
- Application guide of XY matrix analysis method of life cycle cost (LCC)
Breakthrough points of implementation benefits
┌───────────────┬─────────────┬─────────────┐ │Strengthen the compatibility design of production lines on the manufacturing side|Improve the reverse logistics network│ΔOptimize the testing and certification links│ ├───────────────┼─────────────┼─────────────┤ │LCC of steel parts reduced by 42% │Extended the replacement cycle of transmission system│Synergy benefit of the whole value chain 27%↑│ └───────────────┴─────────────┴─────────────┘
