Abstract：A methodology based on decision tables for the fault tree construction of the process control sys-tem is proposed, which is a step-by-step way to find the structure function.By means of binary state deci-sion tables with the condition stub of events and the condition entry of 0 and 1 , all the possible state com-binations of the events are listed.According to the interactions between parts under every circumstance, the output event can be deduced.In way of finding the union sets of the event sequences with the same consequences, the repeated events and irrelevant events can be ruled out and the reduced structure func-tion can be achieved.Verified by the fault tree modeling of nitric acid cooling system, the fault tree a-chieved in this way is consistent with the one in the original text.
