Study on optimum transport system of environmental resources-system dynamics approach

Interest in environmental problems has risen, and life cycle analysis (LCA) of the recycling system in waste treatment has attracted much attention. Under the present conditions, the sludge is not necessarily treated appropriately from the point of view of environmental control. Therefore, the flow of sludge in sludge treatment was modeled from a point of view of flow control. Here the sewage treatment process that is a part of sewage treatment system was modeled by using the technique of system dynamics. The program for treating the flow was made by using a personal computer and the system constitution that could cope with various conditions was examined. As a result, it has turned out that the system dynamics is a useful technique for obtaining the result corresponding to the change of environmental factors
