| Abstract: | The deterministic dynamic vehicle allocation problem with homogeneous vehicle type is defined.And the network chart is used to depict the problem.The linear programming model is expressed.Owing to the shortcoming of the model,a particular linear function is devised to approximate the recourse functions from next time period to the end of the planning horizon through the use of the aproximation techniques.So the new-style model is formulated.And the problem by time and space is decomposed into a series of lo... |
