چکیده:
Undoubtedly, each organization thinks to evaluate its controlled units’ performance to use its resources optimally that data envelopment analysis is one of the most applied method of evaluating performance. This is non-parametric method in field of research in operations measuring the attributed relationship between inputs and outputs to various units and also their performances. Since various models have been developed using data envelopment analysis in past years to be used, selecting a proper model to evaluate and measure efficiency of studied units is so important step. In this research, DEA is proposed and CCR linear planning model and LINGO software were used to analyze efficiency of coloring lines in Mehr cam Pars co. of Iran Khodro industrial group. It was tried in this research to proposed efficiency of coloring production units, advantages, and disadvantages of their ranking, and having some suggestions to increase units’ efficiency which are in lower levels..

In this research, DEA is proposed and CCR linear planning model and LINGO software were used to analyze efficiency of coloring lines in Mehr cam Pars co.
Introduction Production units are needed to assess the criteria taken into account the fact that the input variables to produce the same unit of output is the ranking criteria and that it is possible to show measure the view the performance of units.
Among the different models available in two basic models of DEA, the analog standard fixed and variable CCR andvariables and criterions evaluating efficiency Ranking productive units BCC are very versatile and easier computer programs available, most of these models are taken and modeling.
In between BCC and CCR model should be noted, if constantIn recent years, due to economic sanctions and reduced foreign substances also reduce the cost of expensive resources and the obligation to remain in a competitive market for the products of manufacturing main target is to improve the efficiency In the meantime the important role in helping plays organizations.
DEA efficiency analysis is an appropriate method to evaluate multifaceted similar units (DMU) is based on multiple inputs and outputs.
In evaluating the performance of products, given that inputs per unit of output than intended constant returns to scale, input-based cover CCR model that is provided by experts in the project has been investigated.
It should also be noted that production managers can according to your desired input and output variables in the model considered appropriate factors and to assess the efficiency of their units.
