SAFETY INTEGRITY LEVEL EVALUATION SUPPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a safety integrity level evaluation support device for more efficiently achieving a target safety integrity level by simulating the safety integrity level of a safety-related system.;SOLUTION: A safety integrity level evaluation support device 2 includes: a storage part 40 for storing a design parameter; an arithmetic part 50 for calculating the SIL (Safety Integrity Level) of a whole system 1 by tabulating analytic values; a display part 60 for displaying the design parameter and the SIL of the whole system 1; and a correction part 70 for accepting the correction value of the design parameter. When the correction value of the design parameter is input by the correction part 70, the arithmetic part tabulates the analytic values as to the whole system 1 on the basis of the correction value, and recalculates the SIL of the whole system 1 on the basis of the pertinent analytic value, and simulates the SIL of the whole system 1 for the case where the design parameter is changed to the pertinent correction value, and displays the SIL on the display part 60.;COPYRIGHT: (C)2013,JPO&INPIT
