PROBLEM TO BE SOLVED: To determine a critical failure removal time between the time when a control object becomes recoverable after failure and the time when the control object becomes unrecoverable after failure.;SOLUTION: A multi-dimensional state variable x⁰ which is the function of critical failure removal time and employed in function f representing the critical state of a control object, a multi-dimensional state variable x^m+1 which makes the function f 0, a plurality of multi-dimensional state variable x^k (1≤k≤m; k is an integer) dispersed between the multi-dimensional state variables x⁰ and x^m+1, and the Euclidean distance ε between the multi-dimensional state variable x^k and x^k+1 adjacent to each other from x⁰ to x^m+1 are determined to minimize the value of a formula, and a critical failure removing time is determined from the multi-dimensional state variable x⁰.;COPYRIGHT: (C)2007,JPO&INPIT
