A DEA efficiency analysis of operating units within electronic shopping stores

This chapter assesses the operating units within electronic shopping stores with regard to their productivity. The methodology used to measure the productivity is data envelopment analysis (DEA). Two different linear programming model formulations of the DEA model are used. In the first linear programming model, the weights are applied to the inputs, with the outputs remaining the same. In the second model, weights are applied to the inputs, but the outputs are different.
