    Oxford, UK : Blackwell Publishing Ltd
    Papers in regional science 72 (1993), S. 0

    Notes: Spatial search is a highly complex decision problem, hi this paper, modeling approaches are developed which alleviate some of the difficulties encountered in analyzing spatial search. A search modeling framework is outlined which states the problem in a sufficiently detailed yet manageable format. Within the framework, an operational model is developed which generates the probability that a feasible search pattern will result in the lowest realized acquisition cost. Solution strategies for the model include Monte Carlo simulation and a pruning rule which can reduce the dimensionality of the problem. Computational experience with the Monte Carlo procedure and the pruning rule is also provided.

    PRICING POLICY REACTIONS TO AGGLOMERATION IN A MARKET WITH SPATIAL SEARCH (1996)

    Notes: . Price dispersion (variation) and agglomeration are common characteristics of spatial markets, in particular, markets with imperfect consumer information and search. However, pricing and location strategies in these markets are not well analyzed since spatial search is difficult to model without restricting the spatial dimension of the problem. This paper analyzes pricing and location strategies in a market with spatid search using a probabilistic modeling strategy that does not restrict search patterns in the plane. Specifically, the analysis considers the pricing strategy of an isolated firm in response to the agglomeration of competing firms. Results indicate that spatial and temporal price dispersion are effective responses to competitors'agglomeration. However, the relative effectiveness of these strategies varies with market conditions. In addition, agglomeration can have some counterintuitive effects. This paper also provides insights into existing theories of spatial search and spatial competition in spatially-restricted (linear and circular) markets.

    SOLUTION STRATEGIES FOR THE SINGLE FACILITY MINIMAX HUB LOCATION PROBLEM (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Papers in regional science 70 (1991), S. 0 
    Details
    ISSN: 1435-5957
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Economics
    Notes: In this paper, the single facility minimax hub location problem is considered. The problem involves siting a hub facility in order to minimize the most costly interaction between a set of fixed nodes. Several solution techniques are reviewed, including: discrete locational evaluation; Helly's Theorem; a graphical approach; linear programming feasibility; and Drezner's round trip location algorithm. A comparison of these approaches favors the Drezner algorithm. The minimax hub location problem and the Drezner solution strategy are illustrated through application to air passenger flows between U.S. Cities.

    Geographic representation in spatial analysis (2000)
    Springer
    Journal of geographical systems 2 (2000), S. 55-60 
    Details
    ISSN: 1435-5949

    Notes: Abstract. Spatial analysis mostly developed in an era when data was scarce and computational power was expensive. Consequently, traditional spatial analysis greatly simplifies its representations of geography. The rise of geographic information science (GISci) and the changing nature of scientific questions at the end of the 20th century suggest a comprehensive re-examination of geographic representation in spatial analysis. This paper reviews the potential for improved representations of geography in spatial analysis. Existing tools in spatial analysis and new tools available from GISci have tremendous potential for bringing more sophisticated representations of geography to the forefront of spatial analysis theory and application.

    Spatial search and spatial competition: a probability analysis of basic results from the spatially-restricted theory (1995)

    Notes: Abstract Existing analyses of the interactions between spatial search and spatial competition are limited since it has been difficult to incorporate the complex routing component of the behavior. This paper examines the interactions between spatial search behavior and spatial competition using a probabilistic modeling strategy that doesnot restrict routing. Experimental analyses examine basic hypotheses from optimal search theory and competitive location theory in the context of spatial search. While experimental results support several of these basic hypotheses, the experiments also generate some contradictions and additional insights.

    GIS Software for Measuring Space-Time Accessibility in Transportation Planning and Analysis (2000)
    Springer
    Geoinformatica 4 (2000), S. 141-159 
    Details
    ISSN: 1573-7624
    Keywords: transportation ; accessibility ; space-time ; user interfaces ; GIS design
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geography
    Notes: Abstract Transportation systems exist to improve individual accessibility. However, emerging applications of GIS in transportation (GIS-T) and intelligent transportation system (ITS) focus on throughput (the amount of system flow) rather than accessibility. Throughput is related but not equivalent to accessibility. Sensitive transportation planning requires rigorous, realistic and tractable accessibility measures. This paper reports on the development of GIS software that implement space-time accessibility measures (STAMs). The STAMs reflect the benefits that individuals receive from the transportation system. They are easily interpreted, particularly with respect to changes in accessibility. The STAMs also consider the locations and travel velocities dictated by the transportation system as well as individuals’ daily activity schedules. Tractable computational procedures allow calculation of the STAMs for detailed, urban-scale transportation networks. A prototype ArcInfo®-linked software system that runs on Windows NT® or Sun Solaris® platform implements the STAMs with user-friendly interfaces and project management tools.
