Abstract:

The factors affecting the allocation efficiency of support equipment in a logistic system are studied at the beginning. The definition of allocation efficiency is presented meanwhile. Basing on the multilevel network model of logistic systems, the forecasting methods for the number of support equipment and the utilization rate are given. The stochastic process of number of products to be repaired obeys Poisson process; the estimating model of the fill rate is developed by using the queue theory. Finally, an example is given to demonstrate the practicability of the presented estimate method.
