Location-inventory system integrated design problem under stochastic demand The location-inventory distribution system design problem involving one supplier, candidate distribution centers and multiple retailers under normal distribution demand is studied in the background of building materials industry. Retailers adopt periodic reviewinventory policy, while distribution centers adopt continuous reviewinventory policy. Considering the trade-off between inventory cost, shipping cost and facility location cost, the integrated 2-echelon inventory control policies with incapacitated facility location model is presented.
