- the worker classification of the worker who has the necessary skills for the work from the work for which no worker was found is determined. It is also possible to search and store the above work, worker classification, date and time, etc. in a log file or the like. For example, if the work for which no worker was found is a machine-related trouble-handling work, the mechanical system engineer can search for the worker classification of workers who have the necessary skills for the work. Work, mechanical engineer, etc. are stored. This indicates that there may be a shortage of mechanical engineers at the factory. Thus, the log file described above increases the number of workers in the factory. It can be used as a material for determining whether reduction is necessary.
- the number of workers is insufficient, and it can be inferred which type of worker is insufficient.
- unnecessary workers can be reduced by reducing the number of workers to the extent that error processing does not occur.
- the required number of workers of the required worker classification can be assigned to the factory, so that the efficiency of work per worker can be improved and the efficiency of the number of workers can be improved.
