Knowledge-based reasoning assembly process planning approach to laser range-finder

This paper presents a based on knowledge reasoning approach to the assembly sequence planning. The DACG (Directed Assembly Connection Graph) proposed provides an appropriate way to express both geometric information and non-geometric knowledge. In order to increase the assembly planning efficiency, the DACG includes engineering knowledge and semantic in design, manufacturing and assembly fields. Product semantic information model could offer much useful information for designer to finish the assembly (process) design and make right decision in that process. The proposed assembly process planning approach is applied to the development of a laser range-finder product successfully. Preliminary experience with the approach indicates the potential to reduce lead times and thereby can help in completing new product launch projects on time.
