Abstract: 
Measuring is one of the basic elements of productivity cycle and acts as a control ‎system for other elements in the cycle. In this article, for measuring productivity and ‎evaluating operation of organizations, a comprehensive model has been designed by ‎using Data Envelopment Analysis models (DEA) that is very accurate and true. The ‎Captioned model has been called "Dynamic Productivity Model" due to the fact that ‎time is considered as a decision making unit in this model‏.‏‎
‎ In this research monthly tangible inputs and outputs have been used, CCR-BCC, ‎BCC-CCR, CCR and BCC have been tested based on data of a big company and CCR ‎has been considered suitable for executing dynamic model‏.‏‎
‎ Evaluating operation by dynamic model is an efficient tool for the managers in order ‎to distinguish the degree of deviation from efficiency in operation in the previous ‎periods, and before facing with new situation, through studying the reason of ‎deviation, they can make necessary planning for improving the efficiency. Also in this ‎research it is possible to compare uncongenial units that are one of the limits of DEA ‎model and also it is possible to evaluate operation of unique organization‏.‏
