GB/T 41353-2022Remanufacturing—Guidelines for life cycle cost analysis of mechanical products (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

Introduction

Remanufacturing of mechanical products is an important part of green manufacturing and an effective means to establish and improve a green, low-carbon and circular development economic system.

It is an important measure to implement the Circular Economy Promotion Law and promote the comprehensive green transformation of economic and social development. Remanufacturing refers to the remanufacturing of blanks The process of professional repairing or upgrading, so that its quality characteristics are not lower than the level of prototype new products. Remanufacturing is the "reuse" of the circular economy To accelerate the development of the remanufacturing industry is an important aspect of cultivating new economic growth points. Remanufacturing Economics and Remanufacturing Solutions Design, technology or process selection are closely related, and economic benefit evaluation is an objective requirement for developing remanufacturing industry and promoting the progress of remanufacturing technology.

Life cycle cost is an important economic evaluation index in the field of circular economy and sustainable development.

Evaluate costs at stages such as remanufacturing, technology or process selection, production planning, product acquisition and end-of-life disposal. for reference. Because remanufacturing has unique life cycle characteristics and product characteristics, and different remanufacturing technology models have an impact on production costs, usage costs Capital, end-of-life costs, and environmental costs have a significant impact. Therefore, the economic benefit analysis of remanufacturing should not only consider the cost savings of the production process.

It is more necessary to analyze the economic benefits of remanufacturing to avoid raw material waste, reduce environmental impact, and reduce user acquisition and use costs.

The guideline for life cycle cost analysis of remanufactured mechanical products is an important part of the remanufacturing management series of standards, The manufacturing standard system is of great significance. The results of life cycle cost analysis can be used to analyze the economic benefits and enterprise performance of remanufactured products.

Reference, guide enterprises to pay attention to the life cycle cost of remanufactured products. The purpose of this document is to standardize the life cycle cost analysis of remanufacturing companies.

It is convenient for enterprises to optimize the life cycle cost composition of remanufactured products and encourage users to choose remanufactured products of high quality and low price. This document can solve Determine the cross-field, cross-industry, and cross-professional application and coordination of remanufacturing, so as to play a good normative role and play an important role in the development of the remanufacturing industry. significance.
