BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulation program generation method for generating a simulation program for realizing simulation using software.

0002

[Background Art] Conventionally, in this type of simulation program generation method, each time each simulation program is generated, algorithms for the operation and functions of a system to be simulated (for example, a network system) are individually programmed. A simulation program was generated by this.

[Problems to be Solved by the Invention] In the conventional simulation program generation method described above, each time each simulation program is generated, algorithms for the operation and functions of the system to be simulated are individually programmed. When the algorithm of the system to be simulated becomes complex or the scale of the system to be simulated becomes large, the number of man-hours required for programming becomes large.

Furthermore, since each simulation program is generated individually as described above, multiple systems (system configurations (for example,
Multiple simulation programs for network systems that have similar shapes (network systems) or systems that have the same configuration but differ only in the characteristic values of the components (for example, the transmission capacity of the transmission line in the network system) can be individually run. The disadvantage is that it is necessary to perform programming on each other (it is difficult to use data from one to generate the other).

In view of the above points, an object of the present invention is to provide a simulation program generation method that can reduce the number of steps required to generate a simulation program.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the simulation program generation method of the present invention.

The simulation program generation method of this embodiment includes a modeling data creation means 2 (means realized by the function of a graphic editor) that creates modeling data 3 based on an operation 1 by the user, and 3 and program module data 5 to generate a simulation program 7; and a program module and program corresponding to graphic characters (icons, etc.) used in a graphic editor that implements the modeling data creation means 2. The program module storage means 6 stores combination information for combining modules.

Next, the operation of the simulation program generation system of this embodiment configured as described above will be explained.

The modeling data creation means 2 displays a graphic character menu listing graphic characters indicating elements that can be components of a system to be simulated (hereinafter referred to as a simulation target system).

[0013] The user uses the function of the graphic editor related to the modeling data creation means 2 to select a graphic character representing a component of the simulation target system from the graphic character menu, and arranges the selected graphic character. Identify the system configuration of the simulation target system,
Parameter values are substituted into parameters prepared for each graphic character to input characteristic values of the constituent elements corresponding to the graphic character.

The modeling data creation means 2 generates modeling data 3 (information specifying the components of the simulation target system, system configuration) necessary for performing the simulation based on the user's operation 1 having the above contents. The modeling data 3 is then passed to the simulation program generation means 4.

The simulation program generation means 4 generates program module data 5 (a number of necessary program modules and connection information necessary for combining the program module groups, etc.) from the program module storage means 6 based on the modeling data 3. A simulation program 7 (a program in which a group of program modules in the program module data 5 are appropriately combined) is generated based on the parameter values, etc. in the program module data 5 and modeling data 3.

[0016]

Effects of the Invention As explained above, the present invention provides a modeling data creation means (means realized by the function of a graphic editor), a program module storage means, and a simulation program generation means. A simulation program can be easily generated by combining a group of program modules stored in the internal memory, and it is also possible to generate a simulation program while visually understanding it by displaying figures and characters using the modeling data creation means. This has the effect of reducing the number of steps required to generate a simulation program.

In particular, when it comes to generating multiple simulation programs for multiple systems with similar algorithms, it is possible to handle the generation of multiple simulation programs by simply changing the method of combining figures and characters or changing only parameter values. This has the effect that the number of man-hours required to generate a simulation program similar to an existing simulation program can be greatly reduced.
