The Early-Warning Model in the Monitoring of Logistics Transportation

According to related statistics, the transportation cost is a primary factor in the whole logistics cost, up to 50 percents. In order to reduce this cost and realize the accuracy and safety of the logistics, to monitor the throughout transportation process becomes very important to the logistics companies. In the latest studies and applications, vehicle tracking has been fulfilled by using GPS which is only restricted to vehicle locating, while the early-warning functions haven't been taken into consideration. This paper firstly introduces traditional technical means used to monitor logistics transportation procedures, and generalizes transportation risks into two types: delay risk and safety risk. In the second part, this paper illustrates the mechanism of the delay risk warning model. This model uses the origin, destination and transfer points, as well as the transportation time window and real time GPS data as the input parameters, to calculate the difference between the scheduled and the actual time, and provides a warning report if delay will happen. In the third part, this paper adopts GIS Spatial Analysis technology to design a set of "if...then..." rules to realize the safety early-warning model. Finally, the paper introduces a GIS-based route modeling software tool — StandardRoute, to support delay risk model and safety risk model discussed above and analyses the positive impact to the society and the economy.
