Evaluation of the optimal location and appropriate provision of the institutions in the fields of hygiene, medical care and welfare ; through simulation using GIS (Geographic Information System)

由于我们利用了数据系统，因此可以在卫生，医疗和福利领域进行调查。但是，我们发现公共机构发布的数据的可靠性非常低。在我们的研究中，通过voronoi图，我们将每个机构的需求量作为一个自变量来处理，从而使估计服务需求量成为可能。当各个设施的需求数量不独立时，该方法可以识别出模型中有关到达迁移长度分布的事物的必要性。在我们的研究中，我们以医院和福利设施为例，使用地理信息系统来寻找合适的机构配置。在系统中，绘制了到达迁移长度的密度分布。在这项研究中，我们可以找到并验证每个设施的适当配置。然而，当我们检查复数设施的验证时，我们发现重要的是使变量具有合理性，因为存在不确定因素。为了适应复杂的设施规划问题，我们必须采用不确定元素，并考虑每个不确定元素之间的相关特征。考虑到不确定因素和相关特征，我们对这些区域进行了研究。然而，由于城市时代有太多不确定的元素，很难对这些元素进行重新排列，也很难进行评价。研究表明，不断地模拟和考虑与城市结构和设施功能有关的不确定因素，如地震灾害、经济波动等，是非常重要的。研究表明，从多个不同的方面和角度对该地区进行调查，并根据客观数据科学地规划综合制度是非常重要的

As we utilized the data system, it became possible to execute the investigation in the fields of hygiene, medical care and welfare.But, as we found that the reliability of the data which the public organization has released is very low. In our research, by voronoi diagram, we made it possible to estimate the amount of service demand, by dealing with the amount of demand of each institution as an independent variable.When the demand quantity of each facility is not independence, it could recognize the necessity of the thing which is modeled concerning the distribution of arrival migration length.In our research, by making hospitals and welfare facilities into example, we used the geographic information system to find the appropriate provision of the institutions.In the system, density distribution of arrival migration length was drawn.In this research, we could find and verify the appropriate provision of each facility.However, when we examine the verification of the plural facilities, we found that it is important to make the variable with justifiability, as there are indefinite elements.In order to correspond to the complicated facility planning problems, we have to take indefinite elements and consider the related characteristic between each indefinite element.Taking indefinite elements and considering the related characteristics, we examined the areas.However, as there are too many indefinite elements in urban era, it was very hard to rearrange the elements and it was very difficult to appraise.From the research, it was suggested that it is very important to simulate constantly and consider the indefinite elements which relate to the structure of cities and function of facilities, such as earthquake disaster, economic fluctuations, and so on.This research suggests that it is very important to investigate the area from many different aspects and angles, and to plan comprehensive institutions scientifically based on objective data
