摘要：
A P-stage network is studied in different time periods here which contains ratio data. Thus a method is given to evaluate the technical efficiency in each time period and overall efficiency after several desired time periods. Also, the efficiency of each stage of such a structure is evaluated in each time period and after several time periods. It has been shown that overall efficiency scores and the efficiency of each process obtained after several desired time periods are not less than to overall efficiency scores and the efficiency of each process in each time period. In addition, a unit becomes efficient after several periods of time if it is efficient in at least one period of time.
