Description
Technical field
The present invention relates to the case study technology.
Background technology
Causality analysis is a kind of typical problem analysis method, and people always attempt to seek the basic reason of not wishing that event produces.The Kauro Ishikawa of Tokyo University has invented famous Cause and Effect matrix method in nineteen forty-three, referring to accompanying drawing 7.Such Cause and Effect matrix can reflect a variety of causes.Each possible reason all is placed on the line.Cause and Effect matrix has shown a lot of reasons that incident takes place, but the linking relationship of the cause and effect between a lot of reasons is not provided.Like this, each reason can have influence on the initial event of not wishing, but the linking relationship between a plurality of reasons but can not be provided.
The causal method that another one is traditional is the cause and effect tree derivation.The cause-effect relationship tree forms the tree-like chain of cause and effect.Can use traditional instrument to form a logical tree structure (referring to Fig. 8), for example U.S.'s reliability center company (Re1iabilityCenter, Inc.of Hopewell, VA, basic causality analysis (RCA) software PROACT3.0 version USA).In each tree chain, the incident before each may be the reason of next event.Therefore, if stoped the generation of a reason, so ensuing all reasons all may be prevented from.
Summary of the invention
One embodiment of the present of invention can be set up a cause-effect relationship tree according to initial problem description.
According to embodiments of the invention, can each incident on the cause-effect relationship axle increase one or more additional case study axle.Additional shaft includes, but not limited to layering axle and/or operating axis.
In another embodiment of the present invention, system provides a kind of guide template of problem analysis.The guide template can prevent to add unwanted cause-effect.
In another embodiment of the present invention, system can automatically generate substituting problem description, and searches solution at this problem description in knowledge base.
