Assembly sequence planning: A Review

Abstract

Background: Assembly process planning (ASP) is the important stage in the process of product design and manufacturing. A reasonable assembly sequence can reduce the complexity of assembly operations, reduce the number of tools and fixtures, improve the assembly efficiency, reduce the assembly time, and reduce assembly costs. Methods: The purpose of this paper is to review the objective function, constraint conditions, and the solving methods of the ASP. Conclusion: The research methods can be roughly divided into three categories: graph-based method, knowledge-based method, and artificial intelligence algorithm, and the advantages and advantages of the three methods are compared. Finally, future research is discussed which could provide reference for the ASP.
