Component mounting system

A component mounting system comprising:

• a mounting machine that configured to produce a component loading board on which a component is loaded;
• and
• a management device configured to manage the production of the component loading board in the mounting machine,
• wherein the mounting machine includes:
• a feeder configured to supply the component;
• and
• a holding member configured to hold the component supplied by the feeder and obtains the component loading board by loading the held component on a board,
• the management device includes:
• a storage configured to accumulate and store, for each use of production factors, management data in which processing state data indicating whether a processing state indicated by at least one of a holding state of the component by the holding member and a loading state of the component on the component loading board is normal or abnormal is associated with each piece of production factor information for identifying the production factors indicating the feeder and the holding member used in the production of the component loading board;
• a processor configured to
• calculate normal processing rate data indicating a ratio of a number of uses when the processing state is normal to a number of uses of the production factors based on a data group of the management data within a period from a prescribed time point to a current time point for each of use time points when the production factors are used within the period, and output a normal processing rate data set with a data group of the normal processing rate data for each of the use time points as one set, in association with each piece of the production factor information;
• and
• generate predicted normal processing rate data indicating a predicted value of the normal processing rate data subsequent to the current time point according to a change in a use variable indicated by at least one of use time and the number of uses of the production factors in association with each piece of the production factor information, based on the normal processing rate data set;
• an operating unit configured to receive input of various commands;
• and
• a display configured to display the predicted normal processing rate data associated with the production factor information corresponding to each of the production factors indicated by a factor selection command when the factor selection command to select one of the production factors is input via the operating unit.
