Accuracy Measures for Timed Petri Nets
Marina Montes-Partida, Ernesto López-Mellado · 2024
The paper is in the scope of quality assessment of discrete-event process models; accuracy measures of timed Petri nets (TPN) are proposed. A TPN$\boldsymbol{N}$is assessed concerning a set of dated event sequences$\lambda_{\tau}$, where the occurrence instant of every event is recorded. The class of TPN addressed assigns real-valued time parameters to transitions as a single value$\boldsymbol{\delta}(\mathbf{t}_{\mathbf{j}})$or an interval of values$\imath(\mathbf{t}_{\mathbf{j}})$; a metric is developed for each kind of timing. The accuracy of$\boldsymbol{N}$is evaluated on [0, 1] by measuring the deviations between the actual event occurrences in$\boldsymbol{\lambda}_{\boldsymbol{\tau}}$and the expected firing instant of transitions in the TPN.
