Abstract: A central processing unit (11) in a call center receives a work request (for example, repair of a home electric appliance) of a client, allocates a worker in charge satisfying a predetermined condition based on the work contents for the received work request, and determines articles needed for the work. The central processing unit (11) then creates work information on the work contents and the articles on one work day for each worker, creates map information including position information on the work place where the work is carried out in association with the work information and the visit order of the work places to which each worker visits on the work day, and sends the work information and the map information to the mobile terminal (51) of each worker. Technicians receive the work information and the map information from the central processing unit, ascertain the work schedules, visit the indicated work places in order, and carry out the works.
