<p>PURPOSE:To provide a simulation device having high reliability and generality in respect to numerical simulation for a system receiving irregular disturbance. CONSTITUTION:The simulation device 10 has an initialized input means 11, an increment generating means 12, an approximate value updating means 13, and an output means 14. The means 11 inputs the initial value of a status variable and a function for describing the system receiving irregular disturbance to the means 12, which generates the time increment of an approximate value by the use of two kinds of random number sequences without using a derivative for a function. The means 13 updates the approximate value by the generated time increment and the means 14 outputs a simulation result. The obtained simulation result gurantees approximation accuracy of 1.5-th order.</p> |
