Calculate of cost and revenue efficiency in projects with controllable and uncontrollable indicators in DEA and DEA-R: a (case study of Shiraz road construction projects)

This study was carried out to propose cost and revenue models for evaluating road and urban construction and development projects in Shiraz (Iran) using Data Envelopment Analysis (DEA) and DEA based ratio data, (DEA-R) techniques. Today, we are encountering controllable and uncontrollable data in some projects. In this research, cost and revenue efficiency models were proposed considering controllable and uncontrollable indicators.

In this research, cost and revenue efficiency model with controllable and uncontrollable indicators in DEA and DEA-R is presented, also by measuring cost and revenue efficiency with controllable and uncontrollable indicators to compare the results between these two models Been paid.

By comparing the results between cost and revenue efficiency models with controllable and uncontrollable indicators in DEA and DEA-R, it was concluded that it is not possible to make a logical comparison between them. But the proposed models can be important in order to use the input to output ratios. In some decision-making units, similar behavior may be present in DEA and DEA-R, but it is not a criterion for general comparison.

 In this paper, a model for measuring cost and revenue efficiency with controllable and uncontrollable indicators was presented, which can be an introduction to provide more models for measuring cost and revenue efficiency under real conditions.
