Zusammenfassung:	A reception electric field intensity or a transmission delay time in wireless communication between each of multiple apparatuses connected to one and the same network and a portable terminal device is measured (Step S101). Degrees of nearness, where a degree of nearness indicates a nearness between each of the multiple apparatuses and the portable terminal device in a numerical value are calculated based on a measurement result in Step S101 (Step S102). One apparatus is selected from among the multiple apparatuses as a candidate target apparatus based on the degrees of nearness calculated in Step S102 (Step S103). The candidate target apparatus selected in Step S103 is requested to execute a predetermined operation (Step S104). A decision on whether or not to approve the candidate target apparatus selected in Step S103 is received from the user, and the candidate target apparatus is identified as a work-target apparatus intended by the user when the user has approved (Step S105).
