<p>PROBLEM TO BE SOLVED: To realize a technique for evaluating environmental costs which can be efficiently structured and corrected by using plural applications. SOLUTION: This system is provided with plural applications 11, 21, 31, and 41 to be used for calculating the environmental costs of products and a mediating agent A for integrally operating each application by communicating with each application based on a preliminarily decided cooperative procedure. The agent A operates communication in a preliminarily decided common format. The applications 21-41 are provided with wrappers 12, 22, 32, and 42 for operating the applications 21-41 according to a request in the common format from the mediating agent A.</p> |
