In this paper, queuing model with heterogeneous arrival, single vacation and breakdown under Neutrosophic hypersoft environment is analyzed. Customer’s arriving in a varied arrival rate is referred to be heterogeneous arrival. Server may become unavailable once for a random period of time is single vacation queuing system. Server may fail at times while serving customers is termed as breakdown. The basic parameters of the model are considered neutrosophic. Here, the steady state equations of the described model are derived. And performance measures and mean system size are calculated.
