Abstract:

Computer Aided Process Planning CAPP integrated with Computer Aided Design CAD and Computer Aided Manufacturing CAM will form the basis of engineeringplanning systems of the future. These systems will have the capability to operate in a paperless environment and provide highly optimized process operation plans. The WELDEXCELL System is a prototype of such a system for welding in shipyards. The paper discusses three significant computer technology advances which have been incorporated into the WELDEXCELL prototype. First is a computerized system for allowing multiple knowledge sources expert systems, humans, data systems, etc. to work together to solve a common problem the weld plan. This system is called a blackboard. The second is a methodology for the blackboard to communicate to the human user. This interface includes full interactive graphics fully integrated to CAD as well as data searches and automatic completion of routine engineering tasks. The third is artificial neural networks ANSs, which are based on biological neural networks e.g. the human brain, that can do neural reasoning tasks about difficult problems. ANSs offer the opportunity to model highly complex multi-variable and non-linear processes e.g. welding and provide a means for an engineer to quantitatively assess the process and its operation.
