Queueing theory has grown tremendously over the years with diverse areas of applications, such as business, industry, bank, communication, and hospital etc. The present paper analyses a queueing model where an arriving customer may join the queue with some pre-assumed probability or balk with complementary probability. In addition, if the customer finds the service dissatisfactory, may take feedback. Balking and feedback affect the queue economically; either it causes loss in customer or provides services again. So, studying these parameters is of paramount importance in this competitive market. Further, we have considered inter-arrival time and service time to be exponentially distributed. After constructing the infinitesimal generator matrix, we have obtained the steady-state probabilities using Matrix-Geometric Approach. Various measurable indicators have been evaluated with the assistance of Maple software and based on these measures; we have presented an expected cost and profit analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
