This necessity is so evident that the lack of an evaluation system is regarded as a symptom of the organization unhealthiness.

BCC input oriented covering model was used to rank the companies under study. Besides, a group of 36 companies were employed as the sample in the present case study of which 9 companies were found as efficient and the remaining 27 companies were regarded as
