Generic programming for diagnostic models

摘要

A system for compiling a machine operable diagnostic system includes a header unit, a component unit, an effects unit, a test unit, and an instantiation unit. The header unit identifies general properties of a system from a generic description in an electronic format which includes at least one category of a plurality of variations. The component unit identifies a plurality of components of a modeled system from the generic description, and adds and separates the plurality of variations to the plurality of components, and each identified component includes at least one type of failure and a probability of the at least one type of failure. The effects unit identifies from the generic description a plurality of observable effects. The test unit identifies a plurality of tests and test outcomes designed to elicit the observable effects. The instantiation unit constructs a procedural instantiation of the machine operable diagnostic system.

1. A system for compiling a machine operable diagnostic system, including an electronic processor, the electronic processor comprising:
a header unit which identifies general properties of a system from a generic description in an electronic format which includes at least one category of a plurality of variations; a component unit which identifies a plurality of components of a modeled system from the generic description, and adds and separates the plurality of variations to the plurality of components, and each identified component includes at least one type of failure and a probability of the at least one type of failure; an effects unit which identifies from the generic description a plurality of observable effects, each observable effect corresponding to at least one type of failure for at least one component; a test unit which identifies from the generic description a plurality of tests and test outcomes designed to elicit the observable effects; and an instantiation unit which constructs a procedural instantiation of the machine operable diagnostic system based on the general properties, the identified components, the identified observable effects, and the identified tests and test outcomes; wherein the constructed diagnostic system includes a Bayesian network of a plurality of nodes and each node is represented by a program variable, the Bayesian network comprising: a component node for each identified component and the component nodes comprise at least a first layer; an effect node for each observable effect to which transitions at least one component node based on the probability of the failure; an observation node for each test outcome to which transitions at least one effect node based on the probability of observing the observed effect in the test outcome, and the observation nodes comprise a visible layer.
