1. A system comprising a tag layout and an industrial vehicle, wherein:
the industrial vehicle comprises storage and retrieval hardware, a user interface, a tag reader, a reader module, and a vehicle controller;
the storage and retrieval hardware is configured to store and retrieve items from selected storage elements positioned along an aisle path;
the tag layout comprises a plurality of individual tags that are sequenced along the aisle path in accordance with a sequence list that is accessible to the reader module;
the tag reader and the reader module cooperate to identify the individual tags of the tag layout;
the reader module (i) compares a succession of identified sequenced tags with at least a portion of the accessible sequence list to determine if the succession of identified sequenced tags is in sequence along the aisle path in accordance with the sequence list, (ii) generates a missing tag signal for a malfunctioning sequenced tag when the comparison of the succession of identified sequenced tags with the sequence list indicates a sequence irregularity in the plurality of sequenced tags, (iii) correlates vehicle functionality with the malfunctioning sequenced tag when the missing tag signal is generated, and (iv) correlates vehicle functionality with an identified tag in the tag layout, tag-dependent positional data derived from the identified tag in the tag layout, or both;
the vehicle controller controls operational functions of the industrial vehicle hardware in response to the correlation of vehicle functionality with the malfunctioning sequenced tag when the missing tag signal is generated and (i) the correlation of vehicle functionality with the identified tag in the tag layout, tag-dependent positional data, or both, (ii) user input at the user interface of the industrial vehicle, or both.
