GIS-based spatial decision support system for grain logistics management
2010
Grain logistics is the important component of the social logistics, which can be attributed to frequent circulation and the
great quantity. At present time, there is no modern grain logistics distribution management system, and the logistics cost
is the high. Geographic Information Systems (GIS) have been widely used for spatial data manipulation and model
operations and provide effective decision support through its spatial database management capabilities and cartographic
visualization. In the present paper, a spatial decision support system (SDSS) is proposed to support policy makers and to
reduce the cost of grain logistics. The system is composed of two major components: grain logistics goods tracking
model and vehicle routing problem optimization model and also allows incorporation of data coming from external
sources. The proposed system is an effective tool to manage grain logistics in order to increase the speed of grain
logistics and reduce the grain circulation cost.
