  The present invention, for example, envisages a floating body type configuration for the design of a floating body to be used in the ocean from the oceanographic conditions in the sea area used and the purpose of utilization, etc., and safety and economics (construction costs, maintenance costs, and The present invention relates to a harmonized design system, a harmonized design method, a harmonized design conversion system, and a program for supporting optimization of a design by automatically performing evaluations such as benefit costs and environmental characteristics.

Conventionally, the design of structures has been entrusted to the know-how and thoughts of skilled engineers and designers, so that the design has been spent for a long time. Further, as the structure is constructed based on the design created in this way, problems such as excess of construction costs such as insufficient strength of materials and increase of required man-hours may occur. Furthermore, even if the structure as designed is completed, there are some cases where the operational cost is high or the energy efficiency is poor, which may increase the environmental load. This is also an advanced intelligent part that is greatly influenced by the knowledge, information, experience, and sensibilities of engineers and designers as well as floating body designs used in the ocean. As a result, it took a lot of time and effort to design. Although when there is a close existing example has been used a method of remodeling based on it, consideration of calculation and safety of the building costs, analysis and evaluated the energy consumption calculation or the like, is less than all of the conditions Unless there was, work to return to the design stage and make corrections occurred.

  From the above, it is necessary to improve the efficiency of a series of procedures for structural design, and it is required to construct a system that can realize an optimal design plan based on safety evaluation. In this respect, in the field of patents, for example, measures as shown in Patent Documents 1, 2, 3, and 4 have been proposed in order to improve the structure design efficiency.

The indoor environment is designed based on the relationship with the environment in the laboratory for realizing the characteristics.

  Because of this configuration, only the arrangement pattern of the electromagnetic wave absorption surface or electromagnetic wave reflection surface in the indoor space related to indoor environment design has to be the indoor environmental conditions to be designed, and the setting items are limited, and module selection at the concept stage I could n’t. It was only possible to evaluate the indoor environment by converting the signal propagation characteristics using the delay spread as a parameter as the signal propagation characteristics.

  Patent Document 2 discloses CAD data of a structure defined by a CAD unit, a mechanical response amount detected by a CAE structural analysis unit, production availability information determined by a production availability determination unit, and a cost calculation unit. The structure is detected such that the correlation with the manufacturing cost information detected by the method is detected, and based on the correlation, the mechanical response amount satisfies the design condition of the structure and can be manufactured, and the minimum manufacturing cost is obtained. The CAD data of the structure is changed until the optimal shape is detected, the correlation is updated based on the changed CAD data, and the optimal shape of the structure is detected based on the updated correlation An optimum shape design system configured by providing a control unit is provided.

  Because of this configuration, design data (for example, weight, shape, and strain related to the cushioning material) can only be input, or CAD data of previously designed cases stored in the database can be stored on the GUI (Graphical). Parameter conversion could not be performed by User Interface) or the like. In addition, it was only possible to evaluate the mechanical response amount, production feasibility, production cost, workability, and economy, and it was not possible to perform module selection or environmental impact assessment at the concept stage.

  Further, in designing a floating wind turbine generator, Patent Document 3 obtains the degree of fatigue damage due to waves from a statistical value of stress due to waves under a plurality of wave conditions, and winds under a plurality of wind conditions. Considering the procedure for obtaining the degree of fatigue damage due to wind from the time series of stress due to wind and the occurrence frequency of each wave condition, the total wave fatigue damage degree obtained by adding all the fatigue damage degrees due to waves in each wave condition is obtained, Taking into account the occurrence frequency of wind conditions, add up the total wind fatigue damage degree, the total wind fatigue damage degree, and the total wind fatigue damage degree by adding all the fatigue damage degrees due to wind in each wind condition And a method for designing a floating wind turbine generator including a procedure for obtaining the combined fatigue damage degree.

  Since such a configuration was adopted, the setting items were limited only to the combination of the wave condition and the wind condition, and module selection at the concept stage could not be performed. Moreover, only evaluation by DF (fatigue damage degree) was made, and economic evaluation and environmental evaluation could not be performed.

  Patent Document 4 discloses design specification input means for prompting input of design specification information such as the structure and material of an equipment structure, structural parameter setting means for setting a structural parameter from the design specification information, and material parameter from the design specification information. Material parameter setting means for setting the parameters together with the statistical distribution, use condition calculation means for calculating the use conditions such as temperature, stress, and strain of the equipment structure from the structure parameters and material parameters, and occurrence of the design target event in a predetermined period Disclosed is a technical idea comprising event occurrence probability evaluation means for calculating probability, risk evaluation means for evaluating risk from the product of occurrence probability and damage amount, and cost evaluation means for obtaining material cost from structural parameters and material parameters. Is.

Because of this configuration, module selection and environmental impact assessment at the conceptual stage were not possible, as described above.
