Selected aspects of indoor positioning based on AIDC elements in warehouse facilities

The article presents classification of automatic identification and data acquisition techniques (AIDC) as well as techniques for indoor positioning of objects supporting logistic processes, including especially warehousing processes. The use of presented solutions and the possibility of combining AIDC technics with indoor positioning systems to increase the efficiency of logistics processes in warehouses were discussed. This combination can make a tool supporting rational decision making for allocation of idling employees and vehicles to warehouse tasks and reducing empty runs on the base of position analyse. Then, the idea of using popular AIDC devices − mobile terminals with and without RFID scanners to track the position of employees was presented and discussed. Mobile terminals can provide information about position, which can be used for the allocation of tasks (the reverse functions of mobile terminals). Review of AIDC techniques in warehouses and industrial facilities, information flow in AIDC techniques, positioning techniques in a closed space, Resources positioning and the efficiency of the warehouse process, typical and new approaches to positioning resources in warehouse, the reverse function of mobile terminals are presented in the article.
