• An efficiency analysis problem of a hairdressing company is addressed in this paper. The service system has the characteristics of different trade area types, multiple workers with different levels, crisp facilities and expenses and customer relationship orientations. A specialized imprecise data envelopment analysis (IDEA) model is proposed so that the efficiencies of stores from different trade areas can be compared and all workers in different ranks are included. The analysis results exhibit that the inefficiency in resource utilization is largely caused by inefficient operation. Based on the measurement results, eight stores and two stores are aimed with high priority for improving the efficiencies in operation and scale, respectively. The regional manager agrees that IDEA is helpful in evaluating relative efficiency and detecting the reasons caused inefficiency. ()
