These, attracted customers are termed as encouraged arrivals. In this paper, we developed a multi-server Feedback Markovian queuing model with encouraged arrivals, customer impatience, and retention of impatient customers. The stationary system size probabilities are obtained recursively. Also, we presented the necessary measures of performance and gave numerical illustrations. Some particular, and special cases of the model are discussed. Keywords: Encouraged Arrivals, Stochastic Models, Queuing Theory, Reneging, Impatience, Feedback. MSC: 60K25, 68M20, 90B22. 1. INTRODUCTION AND LITERATURE SURVEY In today’s era of cut throat competition, companies compete not only with local markets but also with the big global players.

In order to ensure sustainable growth, firms release various offers and discounts to retain old customers and to engage new ones. The discounts and offers attract customers towards the particular firm. Those, attracted customers are termed as encouraged 334 . Som and S.
