| Research Abstract |
The purpose of this study is to divise a new method of allocation of "obnoxious facilities", which are supposed to be disliked by many inhabitants, such as the garbage incineration plant and the sewage disposal plant. This method includes variables relating to both the distance between the facilities and the inhabitants around them, and the natural-social condition.
First, we extracted various published information about obnoxious facilities, and classified it. Second, we categorized location problems of those facilities by objective functions of optimization, and formulated them : (1) minimization of the amount of obnoxiousness, (2) relief of the inhabitants and area fuffering the greatest damage, (3) equalization of the amount of the obnoxiousness. In addition, we also formulated (4) consideration of the environmental conditions ; minimization of the damage of the air pollution, the radio interference and so on.
In order to understand the basic nature of each location problem, we measured the appropriateness of the location, under the condition that single facility is installed in the area, and tried to express it as equivalent lines. As a result, in the area hypothesized that the inhabitants are distributed uniformly and densely, both the periphery and the cneter of the objective area can be an optimal location of an obnoxious facility. Thus we found that the location problem of obnoxious facilities leads to which objective function we attach importance. Therfore, we devised a procedure to conprehensively dicide an optimal location of the facility by the summation of weighted parameters of each objective function. As a concrete application of this processing, we take up the location problem of a garbage incineration plant at Meguro Ward in Tokyo, and compared and evaluated the logically optimal location, the nominated location and the present location, and discussed the results.
