Abstract
Assembly planning plays a major role in the manufacturing industry In order to reduce computational complexity this paper presents a knowledgebased approach to the assembly sequence planning problem The CSBAT connectionsemanticsbased assembly tree hierarchy proposed in this paper provides an appropriate way to consider both geometric information and nongeometric knowledge In this research the typical or standard CSBAT is applied to a given assembly problem The structure of the KBASP knowledgebased assembly sequence planning system is proposed and there are different ways to construct plans for a CSBAT by retrieving the typical base by retrieving the standard base and by geometric reasoning The approach proposed in this paper can generate assembly sequences for each CSBAT directly without the problem of merging plans for different child CSBATs The application shows that the knowledgebased approach can reduce the computational complexity drastically and obtain more feasible and practical plans
