Abstract
Generating and atracting movements is a phenomenon of need for distribution in a zone in a region. Movement distribution model has an important role to increase economic and regional growth. The model design strategy is determined based on alternative supply and demand generation and the atractionl of movement. The need for strategies to limit supply and demand is determined by restrictions on generation or atraction of movement. The method of limiting the generation or atraction of movement as a distribution system model solution is single constraint. Distribution system modeling with one limitation is based on gravity modeling. Distribution system simulation modeling is built the gravity algorithm. Distribution system starts from constructing generation models with variables that determine the generation of movement. The socio-demographic, infrastructure and freights vehicle are used in this variable modeling. The model was tested with statistical parameters with a test of determination and correlation test. Distribution system modeling is then accumulated in computational models of basic matrices that are defined based on the specified zone. The matrix iteration process in the model calibration will determine results of distribution system model with results of matrix convergence defined.
