An Algorithm for the Calculation of Progress or Regress via TOPSIS and Malmquist Productivity Index

In this paper, the TOPSIS method is used for two times t and t + 1. In order to calculate the progress or regress via Malmquist index, the positive and negative ideal and negative ideals at time t and t +1 are calculated first, then we consider the distance all of the possible alternatives among by positive ideal and negative ideal at time periods of t and t + 1. Then we calculate the distance of all the Aj for the positive ideal and negative ideal for the other time period. Then we use the Malmquist productivity index to calculate the progress or regress of all Aj.
