A queueing-inventory model for different classes of customers with selected service using gwcr eye shape fuzzy number

This paper consider a fuzzy queueing – inventory model with different classes of customers and the services of customers are considered to be selected.. The steady state probability distribution and the other performance measures are derived by using the inventory level state transitions equations. The eye shape fuzzy number is defined and its properties are given. Our proposed model have been considered in fuzzy environment. The parameters involved in this model are represented by eye shape fuzzy number. The total cost is defuzzified by the Generalised weighted canonical representation(GWCR) of eye shape fuzzy number. Then by using the MATLAB software the global optimum total cost are found.
