Visualization for management of electronics product composition

There are some systems called Supply Chain Management system or Value Chain Management system that manage production. It is a powerful tool in normal cases, but in a problem such that some parts are out of stock, it can solve the problem only by simple solutions, like postponing shipping of the product. Because it does not have enough information about production and functions to use the various information. Our research is concerned with a system to integrate information about production and show a solution to help users to judge which way is better to solve the problem. We implemented a prototype system. It takes inputs of some information that were not integrated in one place in former systems, but distributed among systems, people, or sections. It shows a solution for a problem making use of the information integrated in the system. The solution comes as process of reasoning to help user to judge what is the best to do in the case. We also implemented the user interface to show the process of reasoning.
