Glossary of terms<br />
• Cardio-Vascular: the business unit within PMS responsible for the development, sales <strong>and</strong><br />
service of Philips Cardio-Vascular X-Ray Systems.<br />
• Cardio-Vascular X-Ray System: system is used to enable diagnosis <strong>and</strong> treatment of patients<br />
with cardiac <strong>and</strong> vascular diseases by using the X-ray imaging technique.<br />
• Cause-to-Effect Reasoning: see consistency-based approach.<br />
• Chameleon: a FRU that is used in the power supply example; it needs voltage.<br />
• Chiller: a FRU that is used in the power supply example; it needs voltage.<br />
• Collimator: a device made from radiation absorbent material such as lead or tungsten, designed<br />
to limit <strong>and</strong> define the direction <strong>and</strong> angular divergence of the radiation beam. This<br />
FRU is part of the environment for the beam propeller movement, <strong>and</strong> used in the power<br />
supply example; it needs voltage.<br />
• Component: one element of a larger system.<br />
• Consistency-based Approach: an approach to fault diagnosis that defines a diagnosis as a set<br />
of assumptions about a system component’s abnormal behavior such that observations of one<br />
component’s misbehavior are consistent with the assumption that all the other components<br />
are acting correctly [11, 25].<br />
• Consistency-based Model: see Consistency-based Approach.<br />
• CRCB: a FRU that is used in the power supply example; it needs voltage.<br />
• Customer downtime: see repair time.<br />
• C/V: See Cardio-Vascular.<br />
• Data Mining: automatically searching large stores of data for correlations between variables.<br />
• Deduction: inference in which the conclusion is of no greater generality than the premises.<br />
• Dependability (dependable): a property that a successful system must have. It can be decomposed<br />
into the more lower level attributes availability, integrity, maintainability, reliability<br />
<strong>and</strong> safety [4].<br />
• Development Costs: a criterion of diagnostic performance that is used in this thesis, namely<br />
all the costs that have to made prior to the start of the diagnostic process (e.g., supporting artifacts,<br />
training sessions for troubleshooters, other prepare actions that precede the operational<br />
phase).<br />
• Diagnosis: see fault.<br />
• Diagnostic Approach: the specific characteristics of a fault diagnosis process (e.g., reasoning<br />
scheme, online or off-line reasoning, automated or manual inference, etc.).<br />
• Diagnostic Engine: MBD engine that produces diagnoses based on a model <strong>and</strong> real-life<br />
observations.<br />
