Simulation and Analysis of a Preemptive Transportation Model Using Flexsim Software

This paper presents a simulation model for a preemptive transportation system where vehicles can have tasks dynamically reassigned to optimize overall efficiency.The model, built using Flexsim software, includes 9 storage areas and 8 vehicles.Exponential distributions, validated with real logistics warehouse data, generate stochastic task arrivals.Recursive logic implements the preemption algorithm.Comparative analysis over a 10-hour duration shows that the preemptive mode increases average transport volume by 13 % and reduces vehicle travel distance by 13 % compared to a non-preemptive baseline.The results demonstrate the value of preemptive transportation in enhancing system responsiveness and operational efficiency.
