Abstract
A computer-executable method for diagnosing trouble causes in telephone cable segments when trouble data are available only for entire cables is presented. This method diagnoses problems in the components of processes when the component location of process problems is not known. It gives a statistical relationship between component attributes and process problem rates, to facilitate assessment and improvement of policies about the process. This method may be used for diagnosing systematic problems in segments of telephone cable connections of given central offices.
Claims10
A method of predicting and diagnosing trouble in a connection having a plurality of components with a plurality of characteristics, the method comprising:
- selecting at least one characteristic common to the plurality of components as a basis for predicting and diagnosing trouble;
- calculating a first value for the selected characteristic common to the plurality of components;
- based on a performance history of the connection, providing a second value representing one of prior trouble or no prior trouble with the connection;
- and,
- determining a probability of trouble in the connection at a given time as a function of the first value and the second value,
- wherein determining includes
- expressing the second value as a function of the first value and a third value, and,
- approximating the third value to permit the function of the first value and the third value to approach the second value, wherein the third value represents the probability of trouble in the connection at a given time.
A computer program product disposed on a computer readable medium for predicting and diagnosing trouble in a connection having a plurality of components with a plurality of characteristics, the computer program product comprising instructions for causing a processor to:
- use at least one characteristic common to the plurality of components as a basis for predicting and diagnosing trouble;
- calculate a first value for the used characteristic common to the plurality of components;
- receive a second value representing one of prior trouble or no prior trouble with the connection, the second value based on a performance history of the connection;
- and,
- determine a probability of trouble in the connection at a given time as a function of the first value and the second value,
- wherein the instructions for causing the processor to determine include instructions for causing the processor to
- express the second value as a function of the first value and a third value, and,
- approximate the third value to permit the function of the first value and the third value to approach the second value, wherein the third value represents the probability of trouble in the connection at a given time.
