Abstract: Types of tire storage and their advantages and disadvantages were introduced, a optimization design method for the tire gravity-type AS/RS with tire rolling principle was proposed in paper.

Abstract: The preconditions of storage pre-schedule and real-time schedule management are wireless access and mobility support technology in aluminum profile logistic, which is vital for the automated storage/retrieval system(AS/RS) and logistics processes, such as intelligent warehousing and shipment. Understandings characters of the current wireless access technologies, applicability of networking mobility schemes, and their cooperation or compatibility with the Internet of things, decide the AS/RS and logistics structure and its whole efficiency. So the relational technologies and schemes are introduced in this paper from bottom to top according to Open System Interconnect seven layers protocols. It reveals that integration of multi-technologies was widely adopted in project implementation, which can be helpful to achieve high quality of mobile Internet access with lesser costs. Moreover, the feasibility of handover simplification and quality of service construction imply the success of schemes in design. Finally the strategic impact factors of the networking mobility support technology for AS/RS and logistics are concluded as overlapping coverage network optimization, delay tolerant network, and quality of service system based on user behavior.

Abstract: An indoor positioning technique combined with wireless sensor network, RFID and photoelectric sensor is introduced into high speed stacker positioning and speed regulating systems. Compared to high precision retroreflective laser ranging sensors, the combined positioning technique can provide absolute addressing with low cost to speed up stackers. An optimization of frequency conversion motor with absolute addressing can increase improve turnover rate and reduce energy consumption of AS/RS systems.

Abstract: We analyze the overall operation process and storage model of U-shaped curve rail type AS/RS, put forward an optimization designing method based on minimal operating time, set up a mathematical model, and make verifications using genetic algorithm which show that this optimization method greatly increases the operating efficiency of U-shaped curve rail type AS/RS, and provides a powerful reference for its application.
