Simulation And Optimized On Process In Cold-Chain Logistics Center Based On RFID

In recent years, with the development of economy, the living standard of people'sliving standard rise continuously, the nutrition of low temperature cold goods is rich, sothere is more and more demand. Make the related cold chain logistics develop rapidly. Atthe same time, cold chain logistics requirements are constantly improved. But overall, ourcountry the development level of cold chain logistics can't meet the demand of the markettotally. How to improve the present situation of the cold chain logistics, and to enhance thecompetitive advantage, the integration of low temperature industry logistics resources isinevitable choice. Therefore, in the low temperature industry set off a logistics center (coldchain logistics center) investment boom.As a new auto-identification technique, RFID, which is more advanced and practicalthan the bar code technology at present. It has become an effective weapon on improvingthe efficiency of logistics, and it has been pay more and more attention by its outstandingadvantages, such as non-easy damaged, non-contact reading and writing, rapid speed ofreading and writing, simultaneous multi-object identification, etc. These advantagesdetermine that auto-identification technology may meet the strict requirements of coldchain. By unify the characteristics of RFID technical and cold chain logistics, this articledesign a complete flow project to improve the cold chain logistics efficiency with RFIDtechnology.This article constructs a simulation model bases on the loading and unloading processof the case cold chain logistics center. Through the simulation runs find that its bottleneck,then design the cold chain logistics flow bases on RFID technology and the cold chainlogistics' correlation theories. Then the builds a RFID application model in cold chainlogistics center after the further research on the changes of process and time attributed tothe RFID technology. Comparing and analyzing each process to the traditional flow, inorder to show the superiority of RFID technology. Finally, optimizing and verifying thefeasibility of the model. Through the RFID technology application, not only shorts theloading and unloading process, reduce the cost, improve the efficiency and service quality of the cold chain logistics, but also has a certain theoretical support for the practicaldecision from the simulation result and provides the reference to the application of RFIDfor relative areas.
