Abstract
The present invention includes a method and system of identifying parts prone to problems. The method includes the steps of establishing a problem threshold, establishing a part type with a problem, determining a problem level with the part type in response to the part type problem level, comparing the problem level with said problem threshold, establishing a production life of the part type, determining if the part type is within a threshold of the production life, identifying the part type as the problem prone part in response to the comparison and the production life determination.
Claims21
A method of identifying a problem prone part type comprising the steps of:
- establishing a problem threshold;
- establishing a part type with a problem;
- determining a problem level with said part type in response to said part type problem level;
- comparing said problem level with said problem threshold;
- establishing a production life of said part type;
- determining if said part type is within a threshold of said production life;
- identifying said part type as said problem prone part in response to said comparison and said production life determination.
A system configured to identify a problem prone part, comprising:
- an interface configured to receive information associated with a part type;
- a repository configured to store said part type information;
- and
- a controller configured to establish a problem with a part in response to said information, establish a problem threshold, determine a problem level of said part type over a time period, compare said problem level with said problem threshold, and identify a problem with a part in response to the comparison.
A method, of identifying a problem prone part type comprising the steps of:
- establishing a parts watch threshold;
- establishing a problem threshold;
- establishing a first time period;
- establishing a part watch time period;
- establishing a part type with a problem;
- establishing a problem level with said part type during said first time period;
- establishing a production life of said part type;
- establishing if said part type is within a theshold of said production life;
- establishing a parts watch in response to said problem level during said first time period exceeding said part watch threshold, and said part type being outside said threshold of said production life;
- establish a parts watch problem level with said part type during said parts watch time period;
- and
- identifying said part type as said problem prone part in response to said parts watch problem level exceeding said problem threshold.
