To clarify the direction of demand forecast and reduce the forecast deviation
a strategy considering dynamic customer demand is proposed for material distribution. Following the historical demand of the customers
a Poisson distribution is used to simulate the changes in demand
and a demand forecasting model is established to obtain the initial forecasted demand for the customers. Then a material distribution model with uncertain demand is constructed. To solve the distribution model
a genetic algorithm with adjustable forecasting demand(GAAFD)is designed. In the local search stage of GAAFD
a demand adjustment operator is introduced. This operator adjusts the initial forecasted demand with a certain probability to obey Poisson distribution of the demand changes so that the forecasted demand can be reduced
and it simultaneously adjusts the customers between vehicles. The customers are moved to the other lowest cargo vehicle and sequenced for the vehicle service. The lowest delivery
