ANALYSIS METHOD, ANALYSIS PROGRAM, AND ANALYSIS DEVICE

摘要

This invention makes it possible to predict the timing at which a failure will occur in a system (100). This analysis device (101) detects that the number (Nt) of a plurality of nodes (#1 through #N) that malfunctioned during a given period (prd) was 2. Then, on the basis of said period (prd) and the detected number of malfunctioning nodes, the analysis device (101) computes and outputs the number (Nper) of nodes that will be malfunctioning per unit time subsequent to said period (prd). The operator of the system (100) looks at said number (Nper) and determines, for example, whether or not nodes should be added to the system (100). For example, if the number (Nper) of nodes malfunctioning per unit time is greater than a number projected by the operator, the operator determines that nodes should be added to the system (100).
