Received 11 November 2014; received in revised form 3 December 2014; accepted 5 December 2014ABSTRACT Recently, a number of evaluation studies on availability of plant were carried out. This studywas conducted to verify of the reliability of a simulation with some variable such as configura-tion of process, failure probability density function and the number of iteration times for thenatural gas liquefaction plant. The error rate of the KICT-RAM solution was evaluated as 0.03~1.79% compared with the result of the MAROS(commercial solution). And the error-ratechange was observed in the range of 0.03~1.75 on the condition of the iteration times as 30,100, 250. As a result the plant availability evaluation approach of KICT-RAM solution was ver-ified as reasonable. However, the careful approach was required to use the solution because theerror-rate increased according to iteration times change.
