7 Claims

1. A performance index value calculation system, comprising:

at least one processor; and

at least one memory device storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:

updating, in response to change in a communication system, stored inventory data indicating, for each element among a plurality of elements in the communication system:

an identifier of the element,

a specific element type of the element,

one or more linked element identifiers, each linked element identifier corresponding to a linked element among an element group linked to the element, and

a current status of a link between the element and each linked element among the element group;

repeatedly acquiring metric data of each element among the plurality of elements in the communication system;

storing, for each specific element type, calculation logic data indicating a calculation logic for calculating a desired performance index value of the specific element type, the calculation logic based on respective performance index values among the acquired metric data of each linked element among the element group linked to a given element of the specific element type;

identifying an element of interest among the plurality of elements in the communication system by the identifier of the identified element of interest in the updated stored inventory data and by the stored calculation logic data for the specific element type of the identified element of interest;

identifying a performance index value among the acquired metric data of each linked element among the element group linked to the identified element of interest; and

calculating the desired performance index value of the identified element of interest by applying the calculation logic indicated by the stored calculation logic data to the respective performance index values among the acquired metric data identified for each linked element among the element group linked to the identified element of interest.
