Research on Evaluation of courier efficiency based on information entropy and data envelopment analysis.

Measuring the efficiency of couriers in the last kilometre and determining the key factors affecting the efficiency of couriers are of great significance to the courier industry in solving the last kilometre problem. According to the distribution process, the indexes affecting the delivery efficiency of couriers before, during and after dispatch are established, the weights of each index are determined by using information Entropy, and DEA model is established to calculate the delivery efficiency of couriers in express outlets. The differences of sorting, dispatching and service ability during the delivery process of couriers are analyzed, the improvement direction of couriers is defined, and the distribution areas and routes are re-divided. The result of optimization is brought into DEA evaluation model. The example shows that the distribution route and time after optimization are less than before, and the distribution efficiency of most couriers is significantly improved.
