Automatic storage and retrieval system and method for operating the same

A method for operating an automatic storage and retrieval system, wherein the automatic storage and retrieval system (AS/RS) is used to connect a user's computer device to an AS/RS programmable logic controller (PLC) through a communication network, and has a first database for storing a plurality of storage bin data each including a material, a corresponding storage bin for storing the material, controlling authorization for identifying the storage bin and an identification number corresponding to the storage bin;

• the method comprising the steps of:
• (1) displaying via the AS/RS a daily required material report in a browser of the user's computer device after a user loginning the AS/RS through an identification number provided for the user, and receiving a material selected from the material report by the user;
• (2) searching via the AS/RS in the first database for a storage bin datum relating to the material selected by the user, and determine if the identification number of the user is identical to that of the searched datum, wherein if the user does not match the searched datum in identification number, then step (3) is followed;
• or else, a corresponding storage bin for the selected material is obtained from the searched datum, and then step (4) is followed;
• (3) sending via the AS/RS a message showing no authorization for handling the selected material to the user's computer device, and returning to the step (1);
• and
• (4) informing the AS/RS PLC to operate the obtained storage bin for storing or retrieving the selected material.
