Over the past few decades, manufacturing has evolved from a more labor-intensive set of mechanical processes ( traditional manufacturing) to a sophisticated set of information techonology based processes ( advanced manufacturing). The advanced manufacturing
systems (AMSs) are the latest manufacturing systems being used in the industries such as flexible manufacturing systems (FMSs), computer intergrated manufacturing systems (CIMS) and reconfigurable manufacturing systems (RMSs) involving use of sophisticated
techonologies like robots.computer aided manufacturing, rapid prototyping, flexible special purpose machines (FSPM),
