Abstract

There is disclosed a computerized method of simulating an investment and return of a merchandise having a life cycle in which a plurality of stages vary with time. A set of first parameters indicative of turning points of time is input to segment the life cycle into the plurality of stages. A set of second parameters, for the plurality of stages, is also input, which define functions of time depending patterns of an amount of investment and patterns of an amount of return. The patterns of the amount of investment and the patterns of the amount of return are connected to generate an investment model and return model throughout the life cycle. A cumulative amount of investment and also a cumulative amount of return are calculated using the investment model and return model.

Claims

1. A computerized method of simulating an investment and return of a merchandise having a life cycle in which a plurality of stages vary with time, comprising:

inputting a set of first parameters indicative of turning points of time to segment the life cycle into the plurality of stages;

inputting a set of second parameters, for the plurality of stages, which define functions of time depending patterns of an amount of investment and patterns of an amount of return;

generating an investment model and return model throughout the life cycle by connecting the patterns of the amount of investment and the patterns of the amount of return; and

calculating a cumulative amount of investment and cumulative amount of return using the investment model and return model.

2. The method according to claim 1, further comprising displaying a logarithmic graph of the cumulative amount of investment and cumulative amount of return.

3. The method according to claim 1, further comprising performing a risk evaluation in the investment or return by changing any one of the set of first parameters or changing any one of the set of second parameters.

4. The method according to claim 1, wherein at least one of the patterns of the amount of return includes a product between a constant profit ratio and a function of time of a sales amount of the merchandise.

5. The method according to claim 1, further comprising calculating a break-even time or return on investment from the cumulative amount of investment and cumulative amount of return.

6. A computer program product comprising:

a computer storage medium and a computer program code mechanism embedded in the computer storage medium for causing a computer to simulate an investment and return of a merchandise having a life cycle in which a plurality of stages vary with time, the computer code mechanism comprising;

a code segment for inputting a set of first parameters indicative of turning points of time to segment the life cycle into the plurality of stages;

a code segment for inputting a set of second parameters, for the plurality of stages, which define functions of time depending patterns of an amount of investment and patterns of an amount of return;

a code segment for generating an investment model and return model throughout the life cycle by connecting the patterns of the amount of investment and the patterns of the amount of return; and

a code segment for calculating a cumulative amount of investment and cumulative amount of return using the investment model and return model.

7. The computer program product according to claim 6, further comprising a code segment for displaying a logarithmic graph of the cumulative amount of investment and cumulative amount of return.

8. The computer program product according to claim 6, further comprising a code segment for performing a risk evaluation in the investment or return by changing any one of the set of first parameters or changing any one of the set of second parameters.

9. The computer program product according to claim 6, wherein at least one of the patterns of the amount of return includes a product between a constant profit ratio and a function of time of a sales amount of the merchandise.

10. The computer program product according to claim 6, further comprising a code segment for calculating a break-even time or return on investment from the cumulative amount of investment or cumulative amount of return.

11. A simulation apparatus for simulating an investment and return of a merchandise having a life cycle in which a plurality of stages vary with time, comprising:

a first input unit configured to input a set of first parameters indicative of separate points of time to segment the life cycle into the plurality of stages;

a second input unit configured to input a set of second parameters, for the plurality of stages, which define functions of time depending patterns of an amount of investment and patterns of an amount of return;

a model generation unit configured to generate an investment model and return model throughout the life cycle by connecting the patterns of the amount of investment and the patterns of the amount of return; and

a calculation unit configured to calculate a cumulative amount of investment and cumulative amount of return using the investment model and return model.

12. The apparatus according to claim 11, further comprising a plotting unit configured to plot a logarithmic graph of the cumulative amount of investment and cumulative amount of return on a display.

13. The apparatus according to claim 11, wherein a risk evaluation in the investment or return is performed by changing any one of the set of first parameters or changing any one of the set of second parameters.

14. The apparatus according to claim 11, wherein at least one of the patterns of the amount of return includes a product between a constant profit ratio and a function of time of a sales amount of the merchandise.

15. The apparatus according to claim 11, further comprising another calculation unit configured to calculate a break-even time or return on investment from the cumulative amount of investment and cumulative amount of return.
