GROP: New Algorithm of Optimal Path for GIS-Based Logistics

The path planning problem has become the most important part in the field of the logistics to cut down the cost of the distribution. But for some special instance, for example, time and traffic jam, purely GIS canpsilat give a direct resolvent. Aiming at this problem, a new method, GROP, GIS and rules-based Optimal Path for logistics, was presented in this paper. Firstly, we institute rules for all special instances according to the actual situation and set weight to the rules. Secondly, we put GIS technology into the logistics system to help it solve the problem of path, and construct a network structure with weight. Experiments show that the algorithm is right, feasible and practical.
