【正文】 material and the ponents except parts procure more time and meet the actual demand. 3) The puter Management System to strengthen the macrocontrol function, so that the production output of each link to meet actual demand. 4) the establishment of finished products and semifinished base to solve the temporary discrepancies of market demand and supply , full productive potential of enterprises. sign of modern enterprise Modern enterprise take the intensive mass production mode. This requires that all sectors of the production process linked closely ,make it into an anic whole. require production management Scientific . Make scientific decisions. therefore, building an automated overhead warehouse system is one of the effective measures. As mentioned earlier, automated logistics system maximize to use the space, best meet 5 the production requirements, reduce the labor intensity, improve production efficiency, strengthen production and materials management, reducing inventory backlog of funds,it has unparalleled advantages. This is required and pursued by a modern enterprise. As a result of puter management and work technology .it is able to make the business leaders quickly grasp all the material information and make engineering and technical personnel, production managers, production technicians timely know information in order to arrange the production process in reason, improve production efficiency possiblely. Inter and enterprise internal work obtain a more businessline connectivitybetween the outside world and enterprise, breaking the information bottleneck, broaden their horizons, Introduced outside and linked inside,these provide a broad and strong technical support. Taking a look at chinese and foreign large enterprise, they have used automated logistics systems usedgradually since the beginning of 6039。 in 1963 puter controlled is took the lead in the overhead storage in the United States, builting the first putercontrolled warehouse. Since then, the automated warehouse in the United States and Europe have developed rapidly and formed a special subject. Mid60s, Japan began the construction of warehouse, and the speed of development became faster and faster, being one of the countries which have the world39。 the late 50s and early 60s appears the tunneltype stacking crane warehouse of the driver operating。 by means of service delivery is divided into straight, bend and transfer trucks three basic forms. Conveyor systems: the main stereo library peripherals, responsible for delivery of goods to or from the stacker crane . Conveyor types are more mon with roller conveyors, chain conveyors, lifting platform, distribution trucks, elevators, belt machine and so on. AGV system: the AGV. According to the guidanceoriented approach is divided into induction and laser guided trolley car. Automatic control system: Drive automated library system, automatic control system equipment. Currently used for the control model Fieldbusbased approach. Stock Information Management System: Also known as a central puter management system. Is a ful
