  1. 1. AS/RS (Automated Storage/Retrieval System) By : HAMID BIN SALAMON
  2. 2. Contents <ul><li>Overview of AS/RS </li></ul><ul><li>Problems of conventional storage system </li></ul><ul><li>About AS/RS </li></ul><ul><li>-concept </li></ul><ul><li>-structure </li></ul><ul><li>-control </li></ul><ul><li>-benefit </li></ul><ul><li>Application example </li></ul><ul><li>Conclusion </li></ul>
  3. 3. Overview of AS/RS <ul><li>AS/RS refers to a variety of computer-controlled methods for automatically depositing and retrieving loads from defined storage locations. </li></ul>
  4. 4. Overview of AS/RS <ul><li>AS/RS are used widely in both Manufacturing and Distribution operations to hold and buffer the flow of material moving through the process to the ultimate end-user. </li></ul>
  5. 5. Problems of Conventional Storage System <ul><li>Much time spend for searching </li></ul><ul><li>lost or damaged products and inaccurate records </li></ul><ul><li>Orders spending too much time in the factory, causing customer deliveries to be late. </li></ul><ul><li>Waste much space </li></ul><ul><li>excess inventory </li></ul><ul><li>Workers are exposed dangers </li></ul><ul><li>=> Need AS/RS </li></ul>
  6. 6. Concept of AS/RS <ul><li>The operation are totally automated </li></ul><ul><li>Computer controlled </li></ul><ul><li>Fully integrated with </li></ul><ul><li>factory and warehouse </li></ul><ul><li>operations </li></ul>
  7. 7. Basic Structure of AS/RS <ul><li>Storage structure </li></ul><ul><li>S/R(storage/retrieval) machine </li></ul><ul><li>Storage modules </li></ul><ul><li>e.g.) pallets for unit loads </li></ul><ul><li>One or more pickup-and deposit station </li></ul><ul><li>External handling system </li></ul>
  8. 8. Basic Structure of AS/RS <ul><li>1. Storage structure </li></ul><ul><li>- which is the rack framework </li></ul><ul><li>- made of fabricated steel </li></ul><ul><li>- supports the loads contained in the AS/RS </li></ul>
  9. 9. Basic Structure of AS/RS <ul><li>2. S/R machine </li></ul><ul><li>- is used to accomplish storage transaction, delivering loads from the input station into storage, and retrieving loads from storage and delivering </li></ul>
  10. 10. Basic Structure of AS/RS <ul><li>3. Storage modules </li></ul><ul><li>- are the unit load containers of the stored material. </li></ul><ul><li>- include pallets, steel wire baskets and containers, plastic tote pans </li></ul>
  11. 11. Basic Structure of AS/RS <ul><li>4. Pick-and-deposit station </li></ul><ul><li>- is where loads are transferred into and out of the AS/RS. </li></ul><ul><li>- generally located at the end of the aisles for access the external handling system that brings loads to the AS/RS and takes loads away. </li></ul>
  12. 12. Basic Structure of AS/RS <ul><li>5. External handling system </li></ul><ul><li>- brings loads to the AS/RS and takes loads away. </li></ul><ul><li> ex:RTV(Robotic Transfer Vehicle) </li></ul>
  13. 13. Basic Structure of AS/RS <ul><li>AS/RS Structure </li></ul><ul><li>- automatically operated </li></ul><ul><li>- can reduce wasted storage </li></ul><ul><li> place </li></ul><ul><li>- protect product </li></ul><ul><li>Read More </li></ul>
  14. 14. Control <ul><li>Using computer </li></ul><ul><li>Principle problem </li></ul><ul><li>- positioning the S/R machine </li></ul><ul><li> within an acceptable tolerance </li></ul><ul><li> at a storage compartment in </li></ul><ul><li> the rack structure to deposit </li></ul><ul><li> or retrieve a load. </li></ul>
  15. 15. Control <ul><li>Positioning method </li></ul><ul><li>1) counting procedure </li></ul><ul><li>     - the number of bays and levels are </li></ul><ul><li>counted in the direction of </li></ul><ul><li>travel(horizontally and vertically) to </li></ul><ul><li>determine position </li></ul><ul><li>2) numerical identification procedure </li></ul><ul><li>    - each compartment is provided with a </li></ul><ul><li> reflective target with binary-coded </li></ul><ul><li> location identifications on its face. </li></ul>
  16. 16. Control <ul><li>Optical scanners are used to read the target and position the shuttle for depositing or retrieving a load </li></ul><ul><li>ex: Scanners read RFID-tags on pallets. (RFID-tags have information like compartment binary-code(position), sections, and etc...) </li></ul><ul><li>Each time a storage transaction is completed, the transaction must be recorded into the computer </li></ul>
  17. 17. Control <ul><li>Computer controls </li></ul><ul><li>- storage transaction can be entered in real-time </li></ul><ul><li>- inventory records can be accurately maintained </li></ul><ul><li>- system performance can be </li></ul><ul><li>monitored </li></ul><ul><li>- communications can be </li></ul><ul><li>facilitated with other factory </li></ul><ul><li>computer systems </li></ul>
  18. 18. Benefits <ul><li>Improve operator efficiency and storage capacity </li></ul><ul><li>Increasing accuracy </li></ul><ul><li>Maximize available storage space </li></ul><ul><li>Reducing labor costs </li></ul><ul><li>Reducing product damage and waste costs </li></ul><ul><li>Increasing customer service (e.g. : fast delivery) </li></ul><ul><li>Real time inventory control </li></ul><ul><li>Removing personnel from difficult working condition </li></ul><ul><li>(such as cold food storage environments) </li></ul>
  19. 19. Application Example <ul><li>Federal Express (FedEx) </li></ul>
  20. 20. Federal Express (FedEx) <ul><li>- They bring a lot of parcels and packages, and sort them with some standards (such as delivery zone) And then they load some parcels and packages into delivery trucks and deliver articles at house </li></ul>
  21. 21. Conclusion <ul><li>AS/RS is in use and can be used many kinds of manufacturing line & distribution centers. </li></ul><ul><li>Using AS/RS with proper design will produce above mentioned many kinds of benefits </li></ul>
