a plurality of unmanned carriers each capable of transferring one of the plurality of racks from one of the box supply zone, a picking zone, and a packing zone to the other, wherein the central control device controls at least one of the plurality of unmanned carriers to transfer the rack, on which order boxes equal to or greater than a first reference quantity located in the box supply zone are loaded, to the picking zone,
wherein in a case in which picking speed of the picking zone is less than a reference working speed, the central control device controls at least one of the plurality of unmanned carriers to temporarily transfer the rack, on which the order boxes equal to or greater than the first reference quantity located in the box supply zone are loaded, to a picking standby zone provided between the box supply zone and the picking zone.
2 . The logistics management system according to claim 1 , wherein the central control device determines a lower limit standard for storing an item set according to the order request, compares the plurality of reference standards with the lower limit standard, and selects any one among the plurality of reference standards.
3 . The logistics management system according to claim 2 , wherein the central control device inputs item information including the number and size of ordered items of the order request into a standardization simulation model to determine the lower limit standard, and where the selected reference standard satisfies: (i) to be equal to or greater than the lower limit size; and (ii) to minimize a size difference with the lower limit standard.
4 . The logistics management system according to claim 3 , wherein the item information further includes at least one among a weight, a volume, and a three-dimensional shape for each ordered item of the order request.
5 . The logistics management system according to claim 1 , wherein the box making system attaches a box label, on which a box identification code is printed, to the order box of the selected reference standard.
6 . The logistics management system according to claim 1 , wherein the central control device assigns different priorities to a plurality of picking work areas in the picking zone, and controls at least one of the plurality of unmanned carriers to transfer the rack, on which the order boxes equal to or greater than the first reference quantity are loaded, to any one picking work area to which the highest priority is assigned, among the plurality of picking work zones.
7 . The logistics management system according to claim 1 , wherein each of the plurality of racks further comprises:
a rack detector for generating rack monitoring data indicating an occupation state of each loading space provided on the rack,
wherein the central control device determines the quantity of the order boxes before picking loaded on the rack located in the picking zone, based on the rack monitoring data collected from the rack detector of the rack located in the picking rack, and
wherein in a case in which the determined quantity of the order boxes before picking is between a first reference quantity and a second reference quantity, the central control device controls at least one of the plurality of unmanned carriers to transfer another rack, on which order boxes of more than the first reference quantity located in the box supply zone, to the picking zone.
8 . The logistics management system according to claim 7 , wherein the central control device determines the quantity of order boxes after picking, which are loaded on the rack located in the picking zone, based on the rack monitoring data collected from the rack detector of the rack located in the picking zone, and wherein in a case in which the determined quantity of the order boxes after picking is between the first reference quantity and a third reference quantity, the central control device controls at least one of the plurality of unmanned carriers to transfer the rack located in the picking zone to the packing zone.
9 . The logistics management system according to claim 8 , further comprising: a packing system for performing inspection work and packing work with respect to the order boxes loaded on the rack transferred from the picking zone to the packing zone.
10 . A logistics management method comprising the steps of:
receiving, by an order processing system, an order request for each order;
selecting, by a central control device, any one among a plurality of reference standards based on the order request, wherein one reference standard is different from another reference standard in at least one among size and intensity;
transmitting, by the central control device, a box making command indicating the selected reference standard to a box making system;
making, by the box making system, an order box of the selected reference standard in response to the box making command, and supplying the order box to a box supply zone;
loading the order box on at least one of a plurality of racks each having at least one loading space; and
transferring, by at least one of a plurality of unmanned carriers, one of the plurality of racks from one of the box supply zone, a picking zone, and a packing zone to the other, wherein the central control device controls at least one of the plurality of unmanned carriers to transfer the rack, on which order boxes equal to or greater than a first reference quantity located in the box supply zone are loaded, to the picking zone,
wherein in a case in which picking speed of the picking zone is less than a reference working speed, the central control device controls at least one of the plurality of unmanned carriers to temporarily transfer the rack, on which the order boxes equal to or greater than the first reference quantity located in the box supply zone are loaded, to a picking standby zone provided between the box supply zone and the picking zone.
11 . The logistics management method according to claim 10 , wherein the step of selecting any one among a plurality of reference standards comprises the steps of:
determining a lower limit standard for storing an item set according to the order request; and
comparing the plurality of reference standards with the lower limit standard, and selecting any one among the plurality of reference standards.
12 . The logistics management method according to claim 11 , wherein the step of determining a lower limit standard comprises the step of inputting item information including the number and size of ordered items of the order request into a standardization simulation model to determine the lower limit standard, and
