In English: I want to conclude a money transfer as soon as possible. The total time of processing is a deterministic 10 min. Therefore, if I make the request at 14:00 hours, the transfer should be complete for sure at 14:10. However, the electronic money transfer system is under attack by hackers, and they probabilistically complicate matters. Starting from 14:00, attacks arrive with i.i.d. (independent and identically distributed) interarrival times that are exponentially distributed with the parameter 1 = 5 min; the time of the first arrival after 14:00, counting from that hour, is again distributed as such, independent of the others. If an attack arrives while my transfer is being processed, the transfer is cancelled, and the attack is parried immediately, both actions assumed to take zero time, and the transfer starts all over again. If no attack is encountered during the transaction, the money transfer is successfully and safely concluded. What is the expected amount of time, after 14:00, the transfer takes to complete, including the processing time in case of success?
