A continuous formulation for a location-inventoryproblem considering demand uncertainty
提出一个连续非线性选址-库存模型，最小化运输、库存、订货、安全库存和设施开设成本，并用启发式算法求解，数值实验验证了算法效率。
We propose a location-inventory model that can be applied to design large supply chain networks. We address a continuous non-linear formulation that minimizes transportation, inventory, order, safety stock and facility opening costs. We solve the non-linear model with an heuristic algorithm that relies on the fact that the model simplifies to a continuous linear program when two auxiliary variables are fixed. We show the efficiency of the algorithm with the computation of numerical experiments.
