Hybrid storage facility

A method, implemented by a system in a storage facility, the system including a first static storage system that is affixed to ground and comprises a plurality of shelves, wherein the plurality of shelves may be arranged at different heights from the ground, wherein the plurality of shelves stores a first set of totes;

• a first dynamic storage system that is transportable and placed beneath a first shelf that is lowermost amongst the plurality of shelves;
• a first robotic apparatus that is configured to transport the first set of totes from the first static storage system to an order fulfilment and replenishment location in the storage facility;
• a second robotic apparatus that is configured to transport the first dynamic storage system from beneath the first shelf to the order fulfilment and replenishment location, the method comprising:
• performing, by a control server,
• mapping a first inventory item to one of the first static storage system and the first dynamic storage system for storage based on:
• (i) a first transportation time of the first robotic apparatus to transport a tote of the first set of totes between the first static storage system and the order fulfilment and replenishment location,
• (ii) a second transportation time of the second robotic apparatus to transport the first dynamic storage system to the order fulfilment and replenishment location, and
• (iii) a set of attributes of the inventory item that includes at least a consumption rate of the inventory item, and
• controlling one of (i) the first robotic apparatus to enable storage of the first inventory item in one of the first set of totes based on the mapping of the first inventory item to the first static storage system or (ii) the second robotic apparatus to enable storage of the first inventory item in the first dynamic storage system based on the mapping of the first inventory item to the first dynamic storage system,
• wherein
• when the first inventory item is stored in the first static storage system, the control server changes the mapping of the first inventory item from the first static storage system to the first dynamic storage system based on a consumption rate of the first inventory item exceeding a threshold consumption rate,
• when the first inventory item is stored in the first dynamic storage system, the control server changes the mapping of the first inventory item from the first dynamic storage system to the first static storage system based on a consumption rate of the first inventory item falling below a threshold consumption rate,
• when the first inventory item is mapped to a different storage system, the control server sends instructions to a robotic apparatus to retrieve the first inventory item and start a process to transport the first inventory item to the different storage system, and
• wherein when the control server changes the mapping of the first inventory item between the first static storage system and the first dynamic storage system, the control server controls one of the first robotic apparatus or the second robotic apparatus to change the storage of the first inventory item based on the changed mapping of the first inventory item.
