Evaluation of Water and Wastewater Companies of Sistan and Baluchestan Province Using Russell Modified Model Based on DEA
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 2
Abstract
Undoubtedly, skilled and expert human work force is the biggest asset and the corner stone of progress in every Service Company and organization. Reinforcing and creating modern skills in work force in order to increase efficiency of the organization have always been in managers and experts’ mind both in profit and nonprofit organization. Therefore, performance evaluation of the organizations is a good strategy to optimize the workforce. It means that the goal of performance evaluation must be improving and upgrading personnel’s capabilities of an organization. So, the study of service companies and organizations has a great importance and many models and methods have been proposed to performance evaluation so far. One of the best criteria for performance evaluation is data envelopment analysis (DEA) model. These models use efficiency of decision making units (DMU) to obtain the amount of advances and retreats of those units in different periods of time. In this research, performance of 15 Water and Wastewater Companies (WWCs) of different cities in Sistan and Baluchestan province has been evaluated in two time periods led to March 2012 and 2013. These 15 cities have been selected randomly from 37 cities. First, input and output indicators were determined and by using Russell modified model, performance of the companies was evaluated in each time period, and then by using productivity index of Malmquist, productivity of companies was calculated in time, and consequently, the performance of WWCs of Sistan and Baluchestan province was evaluated. Keywords: data envelopment analysis (DEA), Russell modified model, Malmquist productivity index, performance evaluation
