Failure cause estimation device and failure cause estimation method
First Claim
1. A failure cause estimation device comprising:
- a first database that stores causes of past failure cases, questions, and replies thereto for each of the past failure cases;
a second database that stores combinations of the questions and the replies, the combinations being used to classify a cause of a failure case; and
a processor coupled to the first data base and the second data base,wherein the processor executes a process comprising;
presenting the combinations of the questions and the replies thereto stored in the second database, as branch conditions;
accepting an input of a new branch condition including a combination of a question and a reply, the combination being not presented as the branch conditions;
storing the new branch condition in the second database;
estimating, with reference to the first database, at least one cause satisfying the new branch condition and at least one branch condition selected from the presented branch conditions; and
presenting the estimated at least one cause as at least one cause candidate.

Abstract
A failure cause estimation device includes: a database that manages the causes of failure cases, questions, and replies thereto for each of the failure cases; a condition presentation unit that presents combinations of the questions and replies managed in the database on a display screen as branch conditions used to classify the cause of a failure case; a condition selection unit that selects at least one branch condition from the presented branch conditions according selection operation; a cause estimation unit that estimates a cause satisfying the at least one branch condition from the contents of the database; and a cause presentation unit that presents the estimated cause on the display screen as a cause candidate.

8. A failure cause estimation method of a failure cause estimation device, the failure cause estimation method comprising:
-
accessing a first database storing causes of past failure cases, questions, and replies thereto for each of the past failure cases, and a second database storing combinations of the questions and the replies, the combinations being used to classify a cause of a failure case; presenting combinations of the questions and the replies thereto stored in the second database, as branch conditions; accepting an input of new branch condition including a combination of a question and a reply, the combination being not presented as the branch conditions; storing the new branch condition in the second database; estimating, with reference to the first database, at least one cause satisfying the new branch condition and at least one branch condition selected from the presented branch conditions; and presenting the estimated at least one cause as at least one cause candidate.

9. A computer-readable, non-transitory medium storing a failure cause estimation program causing a computer to execute a process comprising:
-
accessing a first database storing causes of past failure cases, questions, and replies thereto for each of the past failure cases, and a second database storing combinations of the questions and the replies, the combinations being used to classify a cause of a failure case; presenting combinations of the questions and the replies thereto stored in the second database as branch conditions; accepting an input of a new branch condition including a combination of a question and a reply, the combination being not presented as the branch conditions; storing the new branch condition in the second database; estimating, with reference to the first database, at least one cause satisfying the new branch condition and at least one branch condition selected from the presented branch conditions; and presenting the estimated at least one cause as at least one cause candidate.
