The Problem of On-line Leasing of DVD Products
Zhang Yun-yang · 2007
According to the relationship between the specific leasing time and period of customers,the probability distributions for them are justified.On the basis of the detailed analysis of leasing process,the formula representing the relationship between storing quantity and leasing period is given,and the probability distribution model for storing quantity is developed as well.The numerical solution is obtained with the data and parameters given in the instance.The keeping quantity with different period distribution and time span are analyzed.Aiming at the optimization problem with given orders,a 0-1 programming model with the restriction on current storing quantity is established and solved with the help of the software Lingo.When it comes to the optimization problem of keeping quantity with given orders,on the condition that the keeping quantity is not restricted,the daily demanding quantity that can maximize satisfaction degree of customers is obtained by making each order meet greedy strategy sufficiently,and the optimization strategy for storing quantity and distributing option satisfying given customer group can be gotten accordingly.
