1. A MULTI-AGENT RFID-ENABLED DISTRIBUTED CONTROL SYSTEM FOR A FLEXIBLE MANUFACTURING SHOP Present by : Ali Vatankhah

2. INTRODUCTION  Nowadays, business globalizations affect the manufacturing enterprises to provide new products with cheaper prices, higher quality, and faster delivery in order to sustain competitive advantage in the turbulent market.  Flexibility, agility, and re configurability are three paradigms which are proven as hazards to enterprise efficiency and profitability and playing a robust roll in this goal.

3. Manufacturing Control system Manufacturing Control - Managing and controlling the physical activities in the factory aiming to execute the manufacturing plans. Normally, a manufacturing control comprises the short-term process plan and the shop floor activities. Three indicators for testing a manufacturing control system  Agility - Ability to support different manufacturing system configurations, machines i.e.  Flexibility - Capability to adapt to new, different or changing environments. In manufacturing world, several flexibility classifications are presented in literature, like mix, changeover, volume, product and sequencing.  Re-configurability - Capability to react in a short period of time to the occurrence of unexpected disturbances (i.e. production environment changes). different production systems scenarios, with a small customization task.(qualitative)

4. Taxonomy of Manufacturing Control Systems

5. Centralized Control Structures  is characterized by a single decision node, where all the planning and processing information functions are concentrated.  Advantage: a better management and control optimization  Disadvantage: low, speed of response, control complexity, tolerance to faults and expandability, specially for large systems.

6. Sensors in Manufacturing Control System For any manufacturing control system a kind of drawback of an excessive dependence on up-to-date information about the products and other elements which move within the system is essential. To address these issues, wireless identification technologies have been developed and introduced over the last decades. Bluetooth and WiFI  Bluetooth and Wi-Fi  Wireless sensors  Bar code  RFID

7. Radio-frequency identification  Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.electromagnetic fields  Tags  Antenna  Reader

8. Bar code in compare to RFID in manufacturing control context  When a part is complex, it may lack a convenient and scan able location for bar codes. RFID tags can be placed anywhere on the part, and scanned from any orientation.  Unlike bar codes, RFID tags can store data for continuous production updates.  Unlike bar codes, RFID tags are unaffected by the dust and grime common to industrial environments.  RFID tags can provide monitoring of the arrival, continuous presence, and departure of specific parts to/from a cell, allowing for better management of routes and locations in the assembly environment.

9. Proposed architecture for RFID-enabled flexible manufacturing shop

10. RESULTS AND DISCUSSIONS The manufacturing lead time is the total time required to process a given product through the factory plant and comprises the setup time, the no-operation time, the idle time, and the processing time.

11. RESULTS AND DISCUSSIONS

12. Conclusion  This work has discussed the multi-agent architecture proposedt o support the design and implementation of an RFID-enabled distributed control and monitoring system for a manufacturing shop. The agents that compose the architecture have been conceived to cover flexibility, agility, and re configurability posed by all the distributed station control agents which it is inspired, and the communication mechanisms needed forth agents to carry out an RFID-based distributed control and monitoring system have been defined.
