  • Refereed, Geographical Review of Japan, The Association of Japanese Geographers, A reinterpretation of Christaller's central place theory : from marketing principle to generalized maximal covering location problem, ISHIZAKI Kenji, Previous research efforts (Ishizaki, 1992) demonstrate that the marketing principle of Christaller's central place theory can be formulated as the set-covering problem. Results from this model applied to a hypothetical lattice network bring up the question of how to generate the hexagonal system of cen-tral places. Christaller required a set of six K-places, located at the median points between their neigh-boring B-places, to cover unsupplied areas about k-d units from B-places (Fig. 1). However, only three K'-places will entirely serve unsupplied areas (Fig. 2). Why are K-places located at the median points between B-places ?
    The primary purpose of this paper is to propose a reinterpretation for solving the above problem and reformulate the marketing principle using a location-allocation model. Furthermore, the relaxed models reflecting real assumptions are developed to expand the notions of the marketing principle. Last, relationships between the marketing principle with the relaxed models in this paper and well-known location-allocation models are discussed, in order to investigate the implications of the market-ing principle.
    Christaller's central place theory insures a continuous type of good and successively inclusive hier-archy. Satisfying these constraints, the supply of goods from a central place is represented as a bundle of outer limits of the range of goods at some central place (Fig. 3). Consider adding the loca-tion of the central place with a bundle of the outer limits of the range of goods. The most efficient location of central place K is at the center point between two B-places on a line (Fig. 4), which where
    aim=demand of node i for good m
    Zim=1 if node i is covered with good m
    Yjm=1 if node j serves good m
    pm=the number of supply points for good m
    wm=weight for good m
    M=the set of good m
    dy=distance from node i to j
    Rm=the outer limit of the range of good m
    Ni(Rm)={j/dijRm}
    Objective function (1) is to maximize weighted demand for good m. Constraint (2) allows Zim to equal 1 only when one or more supply points of good m are established at sites in the set Ni(Rm). The number of supply points of good m is restricted to equal pm in constraint (3). Constraints (4) and (5) insure successively inclusive relaxation: the former defines which supply points for some good q possess good r; the latter defines which demand points covered by some good s are likely to be suppl- ied good t.
    Consequently, the marketing principle and the relaxed models are summarized in Table 2 and in the linked well-known location-allocation models (Fig. 7). The relaxed models are based upon the max- imal covering location problem (MCLP), which is useful for public facility location planning (especial- ly emergency medical services). GMMP has all the characteristics of maximal covering extensions. Therefore, GMMP expanded from the marketing principle is defined as the generalized maximal covering location problem integrating MCLP and its extensions. This definition may make the marketing principle interpretable as the basis of various contemporary public facility location models., 1995, 68A, 9, 579-602, 602, 10.4157/grj1984a.68.9_579

  • Refereed, Comprehensive urban studies, 東京都立大学都市研究センター, MDPREFによる都市公園の選好分析, ISHIZAKI Kenji, 本稿は、東京区部とその周辺に位置する親水性の8公園(井の頭恩賜公園、水元公園、有栖川宮記念公園、葛西臨海公園、上野恩賜公園、日比谷公園、浮間公園、和田堀公園)を対象とし、都市公園の選好構造を解明しようとした。175人の大学生・院生に対し、1公園につき1セット4枚の写真からなる合計8セットの写真を呈示し、8公園の選好順位データをえた。この175人 x 8公園の選好順位行列に対しMDPREF(選好データを分析するためのベクトル・モデル型ノンメトリックMDS)を適用し、2次元のジョイント空間を求めた。葛西臨海公園と上野恩賜公園が正の大きな値をとり、有栖川宮記念公園と和田堀公園が負の大きな値をとるジョイント空間の第1軸は、「調和がとれた自然環境」を表わす選好次元、同じく日比谷公園と上野恩賜公園が正の大きな値をとり、水元公園が負の大きな値をとるジョイント空間の第2軸は、「開放性」を表わす選好次元と解釈された。選好の個人差は、この二つの軸に対する各人の重みづけの違いによって生じているのである。This paper is concerned with a preference analysis of eight city parks with waterside landscape in and around Tokyo City (Fig.2). Eight sets of photographs,each of which consists of four landscape scenes for one park(see Appendix 2),were presented to 175 undergraduate and graduate students as the sample. Then they were asked to see the photographs to rank the parks in term of their preference. A preference ranking data-matrix thus obtained serves as the input for MDPREF (Chang and Carroll, 1968),a non-metric MDS algorithm applied to preference data,to represent the preference structure in a two一dimensional joint space. Interpreting the recovered joint space (Fig.3),based on external information or individual respondents' reasons for their evaluations,leads to a conclusion that the two dimensions of "harmonious natural environment" and "openness" underlie the respondents' preference judgements of city parks: for the former dimension,Arisugawanomiya Memorial Park and Wadabori Park are highly evaluated and Kasai Seaside Park and Ueno Park low evaluated; for the latter dimension,Mizumoto Park is highly evaluated and Hibiya Park and Ueno Park low evaluated. Inokashira Park and Ukima Park,in a sense,appear to lack distinguishing features since they are ambiguously evaluated for the both dimensions. These results suggest that the parks covered with green and/or those full of an open atmosphere are preferred while the parks impressing respondents artificially are less preferred., Sep. 1993, 49, 47-66, 66
  • Refereed, Geographical review of Japan, Series B., The Association of Japanese Geographers, 立地-配分モデルによるクリスタラー中心地理論の定式化の試み, ISHIZAKI Kenji, This paper reconstructs the marketing principle of Christaller's central place theory using the location-allocation model. According to the marketing principle, the system of central places is constructed in terms of the upper limit of the range by satisfying the following constraints :
    (a) All consumers must be supplied with all goods from central places.
    (b) The central places at a higher-level offer not only same order goods but also all the other goods of a lower-level (i. e., successively inclusive).
    In this way, Christaller's requirement organizes the system of central places which is based upon the condition of a minimum number of central places (Saey, 1973). Therefore, the marketing principle is formulated as the set-covering problem which minimizes the number of central places required to satisfy the demand for coverage subject to the maximum distance constraint. The model can be represented as a hierarchical programming (Daskin and Stern, 1981),
    miniZm=WΣxjmj+ΣjSim (1)
    subject to
    Σjaijmxjm-Sim=1 (2)
    xjm-xj(m-1)_??_0 (m=2, ……, L) (3)
    Sim_??_0 (4)
    where dij=the distance from demand node i to potential center site j; Rm=the range of good m, W=a very large positive weight;aijm=1 if the distance from i to j is less than or equal to Rm, 0 otherise; xjm=1 if good m is offered from node j, 0 otherwise; Sim=number of additional central places capable of serving node i with good m.
    The objective function (1) has two hierarchical objectives : the primary objective is to minimize the number of central places; the secondary objective is to minimize the extent of market overlap. Constraints (2) and (4) define the above constraint (a) in Christaller's theory. Constraint (3) insures that the hierarchy is successively inclusive (i. e., the above constraint (b)).
    The model is applied to a hypothetical lattice network (Fig. 5) which is composed of two parts : an inner network where the entry of central places is possible and all nodes must be served from central places; and an outer network where nodes are not potential center sites but demand nodes that do not have, to covered with all goods. To build the hierarchy, both the top-down method and the bottom-up method (Fig. 3) are applied. Results are summarized as follows :
    (1) As can be seen in Fig. 8 and Table 3, the system of central places generated by the bottom-up method is that of the K =3 system developed by Christaller. The solution result using the top-down method (Fig. 7 and Table 2), however, clearly does not fit Christaller's K =3 system. The system generated by the latter method reveals a complicated configuration of central places and has a number of hierarchical levels.
    (2) As compared with the result by the top-down method, we notice that the system built using the bottom-up method is characterized by a concentration of functions (Fig. 9) and, therefore, shows efficient hierarchical organization.
    Consequently, the above model is valid only if it is constructed by the bottom-up method. In order to generate the K=3 system by the top-down method, it is necessary to reinterpret Christaller's objective function., Oct. 1992, 65A, 10, 747-768, 768

The model is formulated with two objectives: (a) minimize the total population uncovered by each service, and (b) minimize the total cost of constructing arcs between centers. Some computational results indicate that the model is possible to derive the flexible system of central place hierarchy., 2015, 50, 50, 37-44, 44

The questionnairing was conducted on 109 households who had changed their residences within Tama City from 1990 through 1995. The results are summarized as follows: the decision to move is related with dissatisfaction with housing conditions of their former residences; movers could search for the new residences in the area not so distant from their former residences because newly constructed houses continue to be supplied near their former residences in Tama New Town being still in the building; moves between the owner - occupied houses exceed those between the owneroccupied house and the rented house since many householders are in their forties and fifties who incline to own their houses; wife's will is likely to be more esteemed in choosing the new residence, and many movers regard housing conditions as the principal choosing criterion while some take into account accessibility and amenity, too., 1999, 70, 5-15, 15

It appears that the distribution of stores in Setagaya ward of this study area is saturated as regards the number of stores and the spatial competitions are intensive through regression analysis between night-time/ day-time populations and the number of convenience stores in Tokyo 23 wards. The stores are classified into seven types of store merchandising and into five types of locational characteristics, applying factor analysis and cluster analysis to the data of individual store's goods from field survey and the measured demand data from trade area analysis using geographic information systems. Consequently, each convenience store firm possesses a specific type of store merchandising for particular market segmentation and adopts a various target market selections according to its marketing ability., 1998, 65, 45-67, 67

The perceptual and preference data on personal judgements of park-landscape scenes were collected through a questionnaire survey of a total of 121 undergraduate students. In order to get a stimulus configuration for an input to PREFMAP, a two-dimensional solution was sought by a non-metric MDS analysis of the perceptual data in terms of park similarity; the two dimensions were interpreted as the relaxed air produced by nature-environment and the perceived extent of urban parks, respectively (Fig.3) . A PREFMAP analysis -phase IV analysis or vector model- using this stimulus configuration revealed that perception of urban parks. that is to distinguish between them, was closely related to their preference judgement., 1994, 53, 57-70, 70

The model was tested on hypothetical spatial arrangements, from regular lattice assumed in central place theory to random arrangement. Furthermore, the model was applied to the hierarchical structure and distribution of Japanese cities restored from past literature and data. As a result of applying the model to numerical examples and real-world data, the conditions of spatial arrangement and hierarchical structure in which properties of small-world network and scale-free network appear have been clarified to some extent. Finally, in order to verify the network properties of current urban system in Japan, the inter-urban linkages measured from business-to-business transaction data were examined. The results represented a markedly scale-free network structure concentrated in Tokyo., kaken

  • Grant-in-Aid for Scientific Research (C), 2005, 2006, 17520544, A Study on the Application of Central Place Theory to the Occupied Area of East, Poland by Nazi Germany., SUGIURA Yoshio; HARAYAMA Michiko; ISHIZAKI Kenji, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Tokyo Metropolitan University, 3700000, 3700000, 1. Before 1937 when Nazi Germany occupied Poland, Upper Shlesia branch of the Reich Association for Area Research had drawn up a plan to reorganize central place networks crossing the border and covering even Polish territories. The central places were planned as the strategic stronghold keeping Polish and other races under German control. 2. It was not easy that central place theory was accepted by Nazi Germany as the settlement location model for the planning framework to reorganize settlements in the occupied area of East, Poland. In 1938 the study group on central places chaired by Christaller was founded in the Reich Association for Area Research, where the applicability of central place theory was discussed to the settlement relocation planning in the future occupied area of East. Of group members, leading disputants were Gottfried Feder who could publish Neue Stadt in no time, economist Friedrich Biilow, and geographer Walter Geisler: Feder seemed to support central place theory; Biilow criticized the theory since it was incompatible with Nazism in that it was constructed positing the liberalistic economy; Geisler disagreed with Christaller who had deduced the hexagonal structure of settlements on uniform space. To these criticisms, as a result Christaller proposed mixed central place theory while changing the tone of argument into pro-Nazism in the papers published in the latter half of 1930s through the first half of 1940s. 3. Actually there was an exemplar as a model for applying central place theory to the occupied area of East, Poland. It was the application to the planning to locate settlements in the IJsselmeerpolders, which was undertaken by technocrats concerned with national land planning in the Netherlands in the 1930s through 1940s. Making good use of their experience which they had accumulated in the occupied area of West, the Netherlands, Nazi Germany intended to plan the settlement relocation in the occupied area of East., kaken

The main motivation of Nazi Germany to apply central place theory to national land planning is due to Konrad Meyer's attention to the theory, who was a professor of agriculture in Berlin University and also the chief of the Reich Association for Area Research. In addition to it, after having finished his Ph. D. dissertation, Christaller got to be connected with volkisch geographers like Friedrich Metz in Freiburg University, and through this channel he was also gradually involved in area planning. 2. In Nazi Germany, national land planners pursued a hierarchically structured country not only to solve an imbalance of population distribution, but also to acquire raw materials and to supply food efficiently. Christaller's extended thesis on settlement system which had been presented at the 1938 IGC in Amsterdam met their needs in that his thesis took into account as that system element reclaimed settlement and industrial settlement as well as central place. 3. Although after Nazi German occupation of Poland in September, 1939, central place theory was going to be applied to spatial planning to reorganize settlements in the eastern occupied areas, the literature in Polish suggests that in advance of it, by the request of the Reich Association for Area Research geographers in Breslau University made a plan in 1937 to construct a central place network in terms of border defenses in Silesia bordered by Poland. 4. Because only citation analysis of relevant literature could not closely capture influences of central place theory upon plans on settlement arrangement proposed by other disciplines, a literature reading work in detail is indispensable in other disciplinary fields. 5. An investigation of Christaller's papers written in 1940s will reveal the process that after 1939 Nazi Germany had actually applied central place theory in occupied Poland., kaken

(1)対象地域における街路灯などの照明装置の分布,犯罪防止の掲示物の分布について現地調査を行ない,収集したデータをベクター型GISに空間データとして入力した.また,「数値地図2500」および「細密数値情報10mメッシュ土地利用」を用いて,対象地域内の土地利用構成をGIS上に取り込んだ.その結果,対象地域の中でも初期に開発された諏訪・永山地区では,街路樹の成長に伴って街路灯が遮られ夜間照明が十分ではないこと,公園などのオープンスペースでは夜間に暗闇が多く創出され,犯罪防止の掲示物もそうした暗闇が創出される場所によく見受けられこと,などが分かった. (2)LANDSAT TMによる観測波長帯のうち遠赤外線の波長帯であるBAND6のデータを用いて,RSによる衛星画像解析を行なった.解析結果に基づく対象地域内の光度分布と,(1)で得た空間データとの重ね合わせ分析の結果,光度分布と照明装置・犯罪防止の掲示物の分布との間には,ある程度の対応関係が認められた.すなわち,夜間の居住環境における暗闇の創出は,対象地域内における土地利用や照明装置のインフラストラクチャーなどの物的環境に起因していることが理解された. (3)ただし,夜間の居住環境に関する住民の意識調査については,満足しうるアンケート調査が実施困難であったため,調査結果が得られなかった.今後は,(1)および(2)で得た客観的な居住環境評価と住民の主観的な居住環境評価とを合わせた分析が必要と考えられる., kaken
  • 奨励研究(A), 1997, 1998, 09780125, 数理モデルによる線形中心地システムの空間分析に関する研究, 石崎 研二, 日本学術振興会, 科学研究費助成事業, 東京都立大学, 2500000, 2500000, 本研究は,海岸線や河川沿いに細長い平野部が存する地域などで,1次元上(線形)に展開する中心地システムを理論的・実証的に検証するものである.平成9年度につづき,線形中心地システムの理論的な分析として,立地ー配分モデルを用いた中心地理論のモデル化と仮想地域における数値実験を行なった.さらに,研究対象地域である福島県太平洋岸のJR常磐線沿線に赴き,資料の収集と現地調査を実施した.その結果,以下の知見が得られた. 1. 福島県太平洋岸の中心地システムについて,商業統計に基づくデータを収集・データベース化し,因子分析による都市的集落の階層抽出を試みた.その結果,対象地域における都市的集落は,ほぼ3つの階層に分類することが可能であり,Parr(1978)による一般階層モデルの適用の結果,上位中心地が2つの下位中心地を包摂する,K=2のシステムに類似していることが示唆された.これは,数値実験による需要分布が1次元上の場合の理論的な中心地システムに合致しており,理論と現実との間に一定の関係が認められた. 2. もうひとつの対象地域である徳島県吉野川流域で同様の分析を行った結果,同地域の中心地システムは階層および中心地の分布ともに,より複雑であることが分かった.これは,吉野川の水運と街道の関係が相互補完的であり,藍染・葉タバコの集散地である都市的集落や新旧街道沿いの集落の発達・衰退など,交通条件の変化が主な要因として考えられる.したがって,現実の中心地システムは,数値実験による理論的なシステムとは必ずしも合致せず,今後は,交通条件を加味したモデル構築の必要性があることが示唆された., kaken

Questionnaires were distribnted to the two types of sampled households which have recently changed residence within Tama New Town and those neighboring to them in order to obtain the data on reasons of residential change and evaluation of residential environment. The average image of the sampled households is characteristic of white-collar. class whose head of the household is in his forties and whose number of household members is four. The main reasons of residential change are attributed to the birth and growth of their children and dissatisfaction with residential environment. Moved households are much more dissatisfied with residence-relevant items such as the size of house and the plan of house than stayed-households. Spatial distribution of composite evaluation of residential environment is analyzed with GIS, so that it turns out that the evaluation depends on topography and accessibility to various, public and commercial facilities. Logit modeling on the decision to move or to stay reveals that the decision to move is well accounted for by residence-relevant variables rather than living-environment-relevant variables such as amenity, safety and convenience., kaken

I made various distribution maps of Zenpokoenhuns according to scale of each Zenpokoenhun, to the geographical condition where it had been located and to the time when it had been constructed. Then I examined the distribution maps based on a nationwide viewpoint. As a result, the burial mounds were made concentratedly in Western Japan at the beginning, to the west of Kinki, but gradually spread through the whole country. And I was able to clarify the local difference between the phase of diffusion of the tombs and diffusive situation in detail. Besides, I tried examination about the association between change of distribution of the tombs and the power of powerful families in every area. In addition, I constructed a "WebGIS database of the Zenpokoenhuns"., kaken

The first was that mountains and rivers used to be primary factors in deciding the location of the capitals,Dazaifu and other cities. Secondly, we clarified that after the constructions of capitals, out of the necessity of Li, attempted to keep the spiritual purity of the capitals and the shape of mountains surrounding the capitals. Thirdly, through the re-examination of historical records, we came to deny a common view that when the government selected the location of the new capitals, they tended to apply the Feng sui system to the surrounding mountains and rivers. To make our conclusions known to the public, we published a report in two volumes; one gathers historical documents and the other is a collection of research papers., kaken
  • Grant-in-Aid for Scientific Research (C), 2009, 2011, 21520800, Edgar Kant's Pioneering Central Place Study in Northern Europe, SUGIURA Yoshio; HARAYAMA Michiko; ISHIZAKI Kenji, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Tokyo Metropolitan University, 4420000, 3400000, 1020000, In 1935 Edgar Kant, an Estonian geographer in pre-World War II, firstly did research to test Christaller's central place theory in the world, which corresponds to the latter half of his Ph. D. thesis. Following Bobek(1935) who had criticized Christaller's methodology to measure the centrality using the number of telephones without taking into account the economic base of urban settlement, Kant classified central places in Estonia based on the industrial population. Soon after then, Kant's study on central places was applied to make a plan of territorial reorganization of municipalities in Estonia just independent of the Russian Empire. This applied work is also the first attempt to apply central place theory to the planning in the world, heralding Germany, the cradle of central place theory., kaken
