  • Publication number: 20220030752
    Abstract: An article management apparatus allocates articles necessary for a board working machine out of the articles stored in a storage based on a production plan of the board working machine that performs a predetermined board work on the board to produce the board product. The article management apparatus includes a first setting section, a second setting section, and a selecting section. The first setting section allows a user of the board working machine to set a restriction condition for each production plan of the board product. The second setting section allows the user to set a priority among multiple priority elements when allocating the articles for the articles needed in a case of producing the board product under the restriction condition set by the first setting section. The selecting section allocates the articles based on the priority of the priority element set by the second setting section.
