Abstract: (1530 Views)
In this study, in order to evaluate the performance of accepted petrochemical companies in Exchange, the scientific method of Data Envelopment Analysis (DEA) was used, which was the common method for evaluation of production and service units. In this method, the efficiency of each unit was maximized, and this led to this fact that input and output weights were varied from one unit to the other and it does not provide the possibility to compare units on a common basis. Moreover; in order to solve it, DEA approach with a common set of weight was used and also principle component analysis was applied. Firstly, by using input-oriented CCR and then Carrillo & Jorge model, which is one of the DEA models with a common set of weights, the efficiency of 20 petrochemical companies, was measured. Calculations were done with SPSS and LINGO software. Eventually, it was indicated that, by deletion of correlation among indexes in CSW-PCA method, the only Khark company reached the highest efficiency.
Keywords: Data Envelopment Analysis, Input-oriented CCR, Petrochemical Companies, Common Set of Weights.
