Abstract:
1. A method, comprising: building a hierarchical representation of a process plan for a manufacturing object using data structures to represent operational flows of the manufacturing object; performing a query execution on the hierarchical representation to determine one or more of the data structures affected by a global flow change (GFC); and implementing a locking protocol, including least a lot plan editor lock (LPEL), flow block editor lock (FBEL), lot plan process lock (LPPL), and global flow change lock (GFCL), to preserve data integrity in the one or more data structures affected by the GFC; wherein the LPEL locks on an experiment object for concurrent editing, the FBEL tracks locking on at least one of a route, subroute, and operation block object, the LPPL locks an experiment object for in-site editing of active flow lots, and the GFCL tracks locking on operation objects for lot movement transaction support before and during the GFC.
