<p>A process control method carried out by a host process controller (2) and local process controllers (10, 11 and 12) is disclosed. The host process controller (2) generates a master file, and a sub-file associated with each process. The master file is transmitted initially to the relevant local process controller (10, 11 and 12). The local process controller automatically updates the file to indicate production progress. This includes updating a status code field for each record which indicates the production status of each individual product. The host process controller (2) receives allocation data via an input/output interface (3) and reads the file at periodic intervals to generate a temporary match table which includes allocation possibilities for end products to destinations. A permanent match table is generated after a pre-set time period and further input signals have been received to indicate desired matching. <IMAGE></p> |
