Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the simulation system of the present invention.

As shown in FIG. 1, first, parameter information input means 1
inputs the parameter reference value A, the parameter value variable range X, and the number of evaluations N as input information necessary to automatically change the value of the parameter selected for simulation.

Further, the execution number storage means 2 stores the number of simulation executions i indicating how many times the simulation has been executed.

Therefore, the parameter value generation means 3 uses the parameter reference value A, the parameter value variable range X, and the number of evaluations N, which are input information of the parameter information input means 1, and the number of simulation executions i of the execution number storage means 2, to Parameter values to be used in the next simulation are calculated and generated using the following calculation formula prepared in advance.

A+XX (i-1)/(N-1) On the other hand, the model data storage means 4 stores in advance model data representing the target simulation model.

Therefore, the simulation execution means 5 executes the simulation using the model data in the model data storage means 4 and the parameter values generated by the parameter value generation means 3, and also executes the simulation execution number i in the execution number storage means 2. is increasing one by one.

Further, the result data storage means 6 receives and stores result data of each executed simulation from the simulation execution means 5 each time a simulation is executed by the simulation execution means 5.

Finally, the graph generation output means 7 generates a graph using the result data stored in the result data storage means 6 for N times, which is the number of times the simulation has been executed, and outputs it to the output device.

The simulation execution control means 8 first activates the 5-parameter information input means 1, and then controls the parameter value generation means 3 and the simulation execution means 5 when the simulation execution number i in the execution number storage means 2 is a parameter. N until the number of evaluations N entered using information input means 1 is reached.
The above-mentioned simulation operation is controlled by repeatedly activating it several times and finally activating the result data storage means 7.

As described above, the simulation system of this embodiment inputs necessary input information and automatically changes and generates parameter values, which are simulation conditions, using a calculation formula prepared in advance. This eliminates the need to create values, and allows input of simulation data, execution of simulation, and output of simulation results to be performed consistently and automatically.
