The scenario based regret and Min-max regret approach for location-allocation model of distribution center, with uncertain parameters

The paper discusses about the location-allocation model for distribution centers under an uncertain environment while demands and transshipment costs change as model parameters. This may leads to large cost deviation in total cost of the model between designed optimal model and real optimal one. Scenario based robust optimization approaches including regret and Min-max regret are proposed based on the stochastic optimization. A Numerical example illustrates the proposed model and the results have been reported. Finally the comparison of results for mentioned approaches has been done for better explanation.
