Then the data were collected using databases and expert opinions and finally, mathematical modeling of dynamic locating was performed to maximize the desirability of selecting the counters offices of Civil Registration in Mashhad and the model was solved by the CPLEX solver with the branch and cut algorithm.

While identifying the indicators of desirability of candidate points, the location of offices in urban areas, the time of reopening and closing, and relevant time period were determined. Activity timing and locating offices, covering 80% of the population and suitable geographical distribution with 39 offices were performed, and optimal value of the objective function was achieved in terms of the indicators considered by the stakeholders and maximum desirability.
