项目摘要

The purpose of this study was to develop methods both for identifying city-rogions and for locating urban facilities. Each method may be summarized as follows;1. Identification of City-Regions (1) City-regions(concentric rings) are identified with interaction data so as to make apparent the differrence between inner- and outer-regions. (2) The nature of each concentric ring is represented as a unity-index which is calcurated with interaction data. The degree of distinction between inner-and outer-regions is given by a boundary-index defined with respect neighboring unity-indeces. (3) City-regions usually have plural boundaries witch enclose the centre-city. (4) In addition to above items, city-regions are identified reflecting both geographical effects and influences due to othe city-regions. Further more, flexibility in the selection of the plural boundary structure allows for characterizations of an entire region according to various purposes.2. Location of Urban Facilities (1) Several urban facilities are to be located at certain sites among the candidate sites. The number of facilities which should be located is a function of the cost of the project. (2) The effects of facility location are represented by the total benefits received by residents who live within a "service radius" distance. Consequently, facility location is expressed as a optimization problem. (3) The benefit recetived by each resident is represented by a "Satisfaction" index. In this study, the Satisfaction index is directly related to the distance between ones resident and a certain facility.

这项研究的目的是开发确定城市区域和定位城市设施的方法。每种方法可概括如下：1.城市区域识别(1)城市区域(同心圆)通过相互作用的数据进行识别，以显示内外区域的差异。(2)每个同心环的性质被表示为一个单位指数，它是由相互作用数据计算的。内部区域和外部区域之间的区别程度由一个边界指数给出，该指数由相邻的单位指数定义。(3)城市--区域通常有围绕中心城市的多个边界。(4)除上述项目外，还确定了反映地理影响和其他城市区域影响的城市区域。此外，在选择多个边界结构时的灵活性允许根据各种目的对整个区域进行表征。城市设施选址(1)几个城市设施将设在候选地点中的某些地点。应选址的设施数量是项目成本的函数。(2)设施区位效应是指居住在“服务半径”范围内的居民所获得的总收益。因此，设施选址问题被表示为一个优化问题。(3)每个居民所获得的利益用一个“满意度”指数来表示。在本研究中，满意度指数与居住者与某设施之间的距离直接相关。
