Finite state automation for emulation of activity sequenced engine

摘要

Disclosed is an apparatus and method to build activity sequenced engine programs from activity function units (AFUs) within a graphical environment. Each AFU is comprised of a set of graphical representations of functional units (FUs). AFUs can be combined with other FUs and previously-created code represented in FU form to build large complex programs which present the same functionality as iterative systems but are easily modified and added to by the user.
