To analyze whether or not the performance of network equipment is sufficiently developed, and to analyze the existence of equipment put in unreasonable operating circumstances unsuitable for the performance of the equipment based on the performance of the equipment connected on the network and the operating circumstances and to output the analyzed information.

This management device acquires the performance information of target equipment (S1), and acquires the operation information of the target equipment (S2), and sets a specific period as the analysis object period (S3), and analyzes the operating circumstances of the target equipment in the specific period (S4), and generates and outputs information showing whether or not the analyzed equipment is properly used based on the acquired performance information and operation information of the target equipment (S5). Here, it is possible to output information for changing the setting destination of the equipment or information for promoting the addition of new equipment on a network.
