Martin Sandberg, Exjobbs-seminarium Statistical Determination of Ignition Frequency Abstract The frequency of ignition is an important variable in the quantification of risk. Actual data and models used for the prediction of the frequency of ignition are now becoming quite dated. In this study, general theoretical models are developed of how the frequency of ignition can be applied depending on the data available. The data collected will allows more closely to examine the frequency of ignition and to apply the developed models.
