[0001]
TECHNICAL FIELD OF THE INVENTION
According to the present invention, data relating to metallic paint can be transmitted via the Internet between a manager (for example, a paint or paint color manufacturing company) and a user (for example, a design department or a paint color approving department in an automobile company). The present invention relates to a metallic paint color management system capable of selecting paint colors and developing paint colors that can be satisfied quickly by the user by transmitting and receiving each other.

[Prior art]
2. Description of the Related Art Conventionally, personal computers have been introduced into most companies and connected via a network, and some kind of information exchange and information sharing has been already performed by e-mail or in-house.
[0003]
However, with the introduction of these, product development, for example, selecting a metallic paint color (new color), which is a specification color for the outer skin of an automobile body, or applying it to paint color development, At present, the speed at which products can be offered to users as products has improved, and it cannot be said that this has led to increased profits in the business and even the company as a whole.
[0004]
In addition, even if information related to product development is crowded, information transmission is limited to a specific person, or information is stored only by a specific person, and information (garbage) data that no one accesses. Bases may be scattered.
[0005]
When thinking about improving the profits of the company here, the sales department in contact with the user plays most of the role, but we introduce knowledge management there and say that we will share wisdom and information with everyone Even if information is provided, much of it is known or obvious and does not seem to be useful for improving the company's profits.
[0006]
Therefore, it was important to consider what knowledge was from the user's point of view, and where to position it in the business was important. However, a personal computer was introduced to the paint company, which is the manager, and each employee became an environment. Even if internal efficiency has increased somewhat, from the user's point of view, there is no relationship or merit, and it is not directly linked to actual profit.
[0007]
Based on these facts, we found a means of creating a conventional metallic paint color and a means of measuring the metallic paint color and converting it into data, and worked on building a system that would help improve the profits of the company.

[0010]
Further, based on the data, the user can develop and select the desired paint color by interacting with the user side, and in order for the product to be viable, create a metallic paint color and measure the metallic paint color. It is important to combine the means for converting the data into data, and the means for storing the data obtained from the data and publishing them on the Internet. Knowledge management can be achieved, and the selection and development of metallic paint colors, which currently takes about 20 to 30 months or more, cannot be shortened.
[0011]
Under these circumstances, in selecting and developing metallic paint colors, which have become a major factor in the product strategy of automobile companies, considering the knowledge seen from the user side, the metallic paint color It is thought that the usefulness of information useful for "decision making" of metallic paint is useful, and that it can lead to the improvement of profits of the company only if it can be provided. Therefore, the development of a “metallic paint color management system” is required.
[0012]

The present inventors have conducted intensive studies to solve the above-described problems, and as a result, considered whether to introduce the idea of knowledge management at the point of contact with the user side, and provided the user with useful information on metallic paint color. , And thought to share information with the user side.
[0013]
Therefore, we developed a metallic paint management system that selects and develops metallic paint by sending and receiving knowledge about metallic paint, that is, the intellectual assets are exchanged between the administrator and the user via the Internet. The invention has been completed.
[0014]
That is, the present invention
1. A system for selecting and developing a metallic paint color by transmitting and receiving data (i) regarding metallic paint colors between an administrator side and a user side via the Internet,
