A Desirable Model for Optimizing the Policy of Service to Customers with Simulation Queue and MCDM Approach

Todays, Post Corporation is played an important role to decrease the traffic mass, air pollution and speedup the works. These organizations are classified as a service organization dealing with costumers and staffs. Every days, these organization is faced with large amount of people which standed in queues.Analysis of queuing systems and decrease the UNFAVORABLE effects of expect is, one of the most noticeable subjects in practical mathematic and operation research. This research is followed above trend. Moreover it is helped to post corporation to decrease their problem providing reasonable services to costumers. First, the problem is defined. Next, system of office queuing is recognized.Finally the total office is chosen in Alborz province for starting special study and determining the way of giving service presentation to costumers as well.As a result, a mathematic model is exhibited based on queuing system structure. The results are shown with Enterprise Dynamic simulation software. The most important advantage of this software is, helped to optimize the system and to predict the function. At the end of study, 4 patterns are also proposed based on experts view. Moreover, three indexes are chosen for evaluation. After all, sequence of models is done based on Topsis Procedure.
