1. An information management device managing information for assisting with maintenance corresponding to an event having occurred in a manufacturing equipment comprising a manufacturing line and a control device for controlling the manufacturing line, the information management device comprising:
a memory; and
a processor, configured to:
store, in the memory, first data relating to data regarding the manufacturing equipment including data relating to an error route in a control flow for the manufacturing line and operation behavior data for the manufacturing equipment relating to a time period before and up to occurrence of the event, wherein:
the control flow comprises a plurality of steps executed by the control device; and
the first data comprises work moving image data of a worker;
classify the event based on the first data relating to the error route and the work moving image data, and generate event information associated with the first data relating to the error route for the classified event, wherein the event information includes one or more pieces;
store second data in which data regarding the manufacturing equipment and maintenance behavior data are associated with each other in the memory, wherein the association of the data regarding the manufacturing equipment and the maintenance behavior data relates to a time period that encompasses before and after maintenance work corresponding to the event;
generate maintenance information corresponding to each piece of the event information by associating the event information for the classified event with the second data;
store the maintenance information which corresponds to each piece of the event information in the memory; and
in response to another event occurring in another manufacturing equipment and being classified the same as the event that occurred in the manufacturing equipment, output the maintenance information on a display device to present information regarding to perform a maintenance work on the another manufacturing equipment and determine that the maintenance work on the another manufacturing equipment has been completed based on a maintenance work completion signal issued from the another manufacturing equipment.
