Frequency Probabilistic Risk Assessment Using Coloured Petri Nets for Telemedicine

Abstract

Recently, threats such as global warming and epidemics have become more serious. For chronic patients, it is desirable to evaluate the residual risks of telemedicine more accurately, including for combined hazards. However, such comprehensive evaluations are difficult to perform using existing risk assessment methods because telemedicine systems are distributed. To the best of our knowledge, existing research does not take the problem sufficiently into account. To assess the residual risk of telemedicine accurately, we study risk assessment using Coloured Petri Nets (CPN) for telemedicine, which is a formal modeling language that is well suited for modeling and analyzing complex systems. We evaluate the residual risks using simulation function by CPN Tools and obtain the residual risks more accurately. Given the results of an experiment we conduct using CPN for telemedicine, we can confirm the probability of not being able to consult telemedicine and other probabilities. Moreover, CPN is found to be well suited for assessing the combined hazards more accurately. This is the first paper of frequency probabilistic risk assessment using CPN for telemedicine.
