Evaluating Shipping Efficiency in Chinese Port Cities: Four-Stage Bootstrap DEA Model

Comprehensive Efficiency Measurement of Port Logistics - Study based on DEA Two-stage Relative Evaluation

Port is an important node in logistics system. Aiming at lack of calculating and analysis for comprehensive efficiency in Port Logistics research, we bring DEA two-stage relative evaluation into this paper, and get production efficiency value and X-efficiency value. Based on these values, a formula for comprehensive efficiency measurement is proposed. Finally, this paper uses this model in maki...

Evaluating port efficiency in the Mediterranean

During the last years, there was rapid development in the world port industry which is considered to have resulted from the increase of universal trade. The key to the development of each port is its adaptability to the earliest developments and its resistance to the increasing competition. The influence zones of each port are characterised by instability, while each port authority aims at the ...

Cost efficiency in three stage network DEA-R processes

In many organizations and financial institutions, we don't always have acsses to inputs and outputs to evaluate the decision-making units (DMUs), but rather only a ratio of inputs to outputs ( or reverse) might be available. In DEA, cost efficiency determines input standards based on input costs. In multi-stage network DEA processes, in addition to input standards, cost efficiency would determi...
