DESIGNING A COMMERCIAL LOCATION-BASED SYSTEM TO SERVE CUSTOMERS BASED ON GIS

Abstract. Finding the desired products and achieving them at the lowest possible cost has always been one of the concerns of in-person buyers. Finding stores containing the desired products is one of the most important services that can be provided to this part of the buyer community. It provided that the costs are minimal, as well as determining the order of visiting the stores and guiding the buyer by routing between store and buyer positions. Transportation is also one of the most important applications of spatial information systems in the field of optimal management of facilities. In this study, routing was performed by Algorithm A*, which was slightly different from the Dijkstra algorithm in terms of accuracy, but in terms of response time, recorded an average reduction of 70%.
