Using GIS for optimal locations of automated teller machines (ATMs) : the case of Stellenbosch

[摘要] ENGLISH ABSTRACT:Automated teller machines (ATMs) are a very important part of our daily lives. They arethe key to accessing our bank accounts. Where they are located can determine how easyor difficult it is to access our bank accounts. ATMs are primarily designed to servecustomers and should therefore be accessible and convenient to the customers. Hence, thequestion of where the ATMs should be located is a prime issue to both the customer andthe bank.A geographical information system (GIS) is a tool that can be used to assist in answeringquestions about locations. It provides a means of determining optimal locations for anyspatially referenced object. Against this backdrop, this study was undertaken to develop amethod with which GIS can be used to find optimal locations for ATMs, takingStellenbosch as a case study.Firstly, it was necessary to understand current factors affecting ATM locations, bothlocally and internationally. An extensive literature survey was conducted to gain anunderstanding of problems relating to locating ATMs. Interviews with bank officialswere conducted to help understand more fully the problems and the current proceduresused in locating ATMs. Obtaining the public's perception of ATMs was also paramountto this study. A household questionnaire survey was conducted in Stellenbosch toascertain how customers feel about the current location of ATMs in Stellenbosch.Secondly, GIS was considered and evaluated as a tool to find optimal locations forATMs. This involved discussing the capabilities of GIS and the various options thatbanks may have available. Thirdly, the ability of using GIS to find optimal sites wastested by applying GIS to Stellenbosch. Having done this, GIS was then used to findadditional ATM sites. The results provide a basis for banks to locate ATMs in general.Keywords: GIS, ATMs, location, optimal locations, location-allocation, models,MINDISTANCE, MAKCOVER, MAXATTEND, MINDISTPOWER.
