Modeling the Goods Transportation Based on Queuing Theory and Simulation Modeling at Pars Service Port

pars service port has been development for import and export of refinery products and equipments and now is one of the most strategic ports in Pars Special Energy/Economic Zone.this port requires to make the best use of the port equipment to survive in the competition environment and achieve anunfailing income.hence a constant need of improvement of port equipment and machineryin felt. now this question pops up that what kind of strategyport management should use to ensure the port survival in competition markets.This article suggests a model for improving sulfur transportation in the inner region of the pars service port in this model we intend to study the trucks movement between the sulfur storage and jetty with a new look to queuing theory and modeling. thismodeling will show the trucks movement from the sulfur stowage area to jetty and tries to improve the trucks number to be used for sulfur transportation. using the load and unload time of a truck and time spent in queuing awaiting for their turn.The result of this model is going show that improvement of sulfur transportation between the sulfur storage area and jetty will reduce the trucks waiting time in the queuing and consequently improves the system efficiency. This article has tried to show a practical model of sulfur transportation between storage area and jetty with integrating subsystem of sulfur transportation in the port and emphasizing on the equipment details. With analyzing the model results the optimal number of the trucks need for transportation of sulfur would be calculated resulting an increase in capacity of sulfur transportation. Also another result of the model is analyzing sensitivity of the demand for sulfur loading that can be used for strategic planning the results of the simulation model is a 33% increase of the port performance.
