Research On The Location Problem Of Distribution Center Based On Uncertainty Theory

The location problem of distribution center is the core problem in distribution centerprogramming. Because the construction of distribution center is a huge investment project,it is difficult to move once completed. If the site selection is improper, it can not only affectits own management pattern, but also play an decisive role in the network layout and thesuccess or failure. So, the study of location problem of distribution center is very necessarybefore investing in the construction of distribution center. In the paper, we study thelocation problem of distribution center via uncertainty theory. Its detailed contents are asfollows.1. We discuss the relation between the solution and parameter for Gao’s uncertain siteselection model. It gets the following conclusion: there is a increasing sequencek,1such that for every j {0,1,2,, k}, optimal solution satisfyingin the model is got in the same vertex.2. First, the expect model is presented by assuming that the uncertain demand in vertexhas uncertainty distribution based on minimizing cost. Then, its the equivalent model isgiven based on Hamiki’s results. Finally, some numerical examples is given in order toillustrate effectiveness of the model.3. In order to minimize total cost, assumed that the operating cost has uncertaintydistribution, an expect-variance-entropy model is constructed based on expect, varianceand entropy of uncertain variable. Then, its equivalent model is given based on Hamiki’sresults. Finally, some numerical examples are given in order to illustrate effectiveness ofthe model.4. In order to minimize total cost and maximize satisfaction degree of times, assumedthat the delivery time has uncertainty distribution, an uncertain model is presented. Then,its equivalent model is given based on Hamiki’s results. Finally, some numerical examplesare given in order to illustrate effectiveness of the model.
