The National Immunization Technical Advisory Group (NITAG) was established in Iran in 1982 and has made many important technical recommendations (e.g., regarding polio eradication, introduction of new vaccines, organizing special studies) that have contributed to a dramatic decline in vaccine preventable disease burden. The NITAG consists of experts from the Ministry of Health and Medical Education (MOHME), vaccine manufacturers, and medical universities with national Expanded Program of Immunization (EPI) staff serving as the secretariat. It is not completely independent from MOHME or EPI. It meets on a quarterly basis, and publishes national guidelines and immunization schedules that are updated regularly. Although primarily an advisory body, representation from MOHME members, including the EPI manager, ensures almost universal implementation of NITAG recommendations.

One of the primary concerns in measuring the relative efficiency of a telecommunication unit compared with other similar units is the uncertainty on input/output data In this paper, a bootstrapped robust data envelopment analysis (BRDEA) model is proposed to measure the efficiency of telecommunication companies The proposed method is capable of handling different issues such as the uncertainty in data or sampling errors The model is examined using some real data from a telecommunication company First, the data from 24 telecommunication companies are assumed with uncertainty and the efficiency of telecommunication companies are estimated using a robust DEA model. Then, the results of the efficiencies are corrected by a bootstrapping technique The results indicate that the BRDEA method considers the perturbation in data and sampling error with an adaptation of bootstrapped robust data envelopment analysis and could be more reliable for efficiency estimating strategies.
