<p>Apparatus for and a method of analysing a process, the method comprising: generating a process template (51); determining a probabilistic model specifying the process template (51) and comprising:task nodesfor tasks (T1–T6) of the process; observables nodes for observables (O1–O7) that may be caused by performance of the tasks (T1–T6); anda background activities node; wherein the observables may further be caused by background activities (B) of the background node;measuring values of an observable corresponding to one of the observables nodes; andupdating a probabilistic estimate of the process state using the measured values. This may be performed to estimate a probability that the measured values are caused by the performance of a certain task (T1–T6) and/or the background activities (B), to estimate whether the process has begun, and/or to estimate which task (T1–T6) is being performed when the measured values are measured.</p> |
