As an application of digital concepts, unattended convenience stores are widely disseminated and considered one of the trends of future business development. It is an important consideration for the development of unattended convenience stores to determine the potential of operation efficiency and improve inefficient units. This paper establishes a bi-level DEA model with multi-followers and uses weak disposability technology to deal with undesirable intermediate measures, aiming to accurately evaluate the performance of the whole bi-level system of unattended convenience stores and each participant. Thus, extended Kuhn-Tucker conditions are applied to solve the proposed model. It is found that the benefit efficiency of the lower subsystem always belongs to the maximum and minimum benefit efficiency of all followers, and the benefit efficiency of the system is between the upper and lower benefit efficiency. Using a case study of unattended convenience stores in the Chengdu area, the validity and practicability of the model in the evaluation of benefit efficiency are shown and more explicit management opinions are provided.
