Determining the Number of Groups in Selective Assembly for Remanufacturing Engine

At present, the world economy is developing rapidly and product life cycle become more and more short. But the resources on the earth are limited, leading to the rapid decline of available resources. For these reasons, sustainable development has become an inevitable choice. As a sustainable strategy, remanufacturing has received the attention of many researchers and is widely adopted in the industry. In this paper, selective assembly for remanufacturing engine is researched. In most research about selective assembly, the number of groups is fixed. In this paper, the number of groups and the range of each group are changeable, and the assembly accuracy is improved efficiently.
