In the reference (1), I propose ＂the drawing method of the figure of the room planning quoted from the graph theory＂ as one of the drawing method of the more appropriate figure of the room planning from the standpoint of the interior design. But this investigation was necessary to study on the specific size of the room.
I analyzed the size of the room planning whose the floor space was 10 m×10 m (100 ㎡). The analytical method is the nonlinear programming in case that the size of the room planning is regarded as the optimal solution. As a result of analysis, it was obtained the realistically effective solution. Moreover, the solution which I tried the sensitivity
analysis was regarded as the optimal solution (the compromise solution).
In this nonlinear programming, the important points on the analysis are as follows.
(1) It was necessary that the basic size of the room planning was to set as realistic as possible under the constraint.
(2) After the optimal solution was obtained, it was effective that the sensitivity analysis was used to adjust finely the values of the objective function.
It became clear that the above mentions were important by simulation.
