Analysis and improvement of the product delivery system of a beer producer in Ankara

We outline our analysis of the product delivery system of a major beer producer in Ankara, Turkey. We demonstrate a savings potential of up to 25% of distribution costs from the implementation of a number of suggested improvements, most notably that of reducing the number of weekly deliveries to a portion of the customers, and of constructing a geographical partitioning of the city that ensures a balanced distribution of the delivery workload over the days of the week. A geographic information system (GIS) is used to extract coordinate and distance information to be used in the partitioning and sequencing problem. A discussion of the difficulties involved in implementing a GIS project in Turkey is included.
