摘要： The present invention refers to a system and a method for probability analysis of a target system (10), wherein output probability signals are generated dependent on generated input probability signals and based on a set of predetermined probability rules and a causal model describing the causality dependencies of the target system (10). The system (1) according to an embodiment of the invention comprises an identifier (20), which receives a status signal from a sensor (14) arranged at a component (12) of the target system (10), wherein the identifier (20) identifies the component (12) associated to the status signal. Further, the identifier can generate an input probability signal dependent on the status signal and the component (12). The input probability signal is then transmitted to a probability analysis apparatus (40), which generates the output probability signal.

摘要： The present invention relates to analysis of sensors and sensor signals using status signals carrying information about the status of components in a flow system. The invention can comprise means for condition checking (31) arranged to determine the alarm state of a function connected via a condition to a goal when the goal is not achieved or means for checking for normal/failed situations (32) arranged to check a function in an alarmed state next to a function in a normal state using consequence propagation rules. Further, the invention can comprise means for full consequence irregularity analysis (33) arranged to assume that one of the alarm signals is erroneous, to check the alarm states using consequence propagation rules and to present the simplified situation if the number of primary alarms are decreased.
