Research on Computational Experiments of Spare Parts Supply System Based on System Dynamic Model
To improve the spare parts supply system efficiency, reduce the spare parts supply cost, and achieve the spare parts supply accuracy, this paper, with the "operation-level to deport-level" support model as its research object, analyses the influence factors of spare parts support ability level of spare parts supply system.It also establishes the operation-level spare parts supply system dynamic model and system dynamic equation, and checks the model to ensure its validity.For the computational experiments, it takes the storage delay time, delivery delay time, supply and demand balance reaction time, supply and demand balance adjustment strength as the experimental factors, and the average inventory and average absolute value of the difference between supply and demand as the object.Experiments show shows that a larger delay time and a larger adjustment intensity of spare parts supply and demand will lead to a larger fluctuation of spare parts inventory level, and a larger time delay will increase the spare parts inventory level significantly.
