Adjusting order-up-to level through simulation optimization of complex logistics;

This paper discusses modeling and simulation of order-up-to levels of entities in CLs in an uncertain environment where periodic review policies are adopted.

The model of simulation and parameter optimization for inventory control is establised,with the time-varying and stochastic characteristics of goods demands are taken into account as well as the stochastic characteristics of the goods arrivals lead-time,under the cosumption that the enterprise take the strategy of controling its inventory with fixed order batch and reorder point.

Research on Order Point of Distribute Center Based on VMI;

At premise that satisfy the customer抯 need, according to the distribution or historic data of lead time and demands velocity, the optimal order point is determined by computer simulation.

In this paper,by means of continual check of fixed order quantity and fixed order point,we establish a inventory control model in grain logistics system.

Based on the analysis of the improvement research into EOQ model,it points out the significance of lead time,and introduces lead time into the order model with vendor-purchaser cooperation.

This paper will first reclassify the inventory by using the method ABC, then propose a (S, s) inventory order model with the function of the safe stock and the highest and lowest amount warning, based on the analysis to the current inventory condition of the third logistics M company, and a true problem happened to a third logistics company has been solved out by using this model.
