Sequence Analysis of Finite Position Machine Fpm

Logic control is an integral part of manufacturing systems. The creation and debugging of the logic control represents a significant amount of the effort needed to design a large manufacturing system. Today's rapidly shifting markets have greatly reduced the life of a product design and the manufacturing system to produce it. As a result reconfigurable manufacturing systems are being developed which are capable of producing different parts over its life. These systems will need control logic, which is capable of being easily reconfigured as the system changes. This work describes the analysis of Finite Position Machines (FPMs) for reconfigurable manufacturing systems thought VS Tree method. VS tree allows to create feasible Pattern structures, whose basically are systems of communicating finite position machines which represent safe reactive processes and allow behavior description.
