Modeling of RFID-Enabled Real-Time Manufacturing Execution System in Mixed-Model Assembly Lines

Algorithm 1

RFID basic event processing algorithm.

Step  1. Receive RFID basic reading events generated by physical readers.

Step  2. Query RFID basic event queue based on , and skip to Step  7 if there are RFID

   basic events with the same tag numbers.

Step  3. Insert into the RFID basic event queue.

Step  4. Search physical object numbers in mapping relation table between objects and tags

   based on ; if none is found, skip to Step  7.

Step  5. Search logical reading events with the same object numbers in logical reading event

   queue according to physical object numbers. If it is positive, skip to Step  7.

Step  6. Assemble into logical reading events according to physical object numbers, and

   insert into logical reading event queue.

Step  7. Abandon RFID basic event; skip to Step  1.
