Abstract
In this paper, we consider a two-commodity stochastic s , S perishable inventory system of the multiqueue Jackson network at a service facility with reneging and jockeying of the customers. The waiting room capacity of the first queue is M / M / 1 / ∞ and the second queue is M / M / 1 / C 2 , where C 2 < ∞ . In this network, different queues have different service rates. Service times are exponentially distributed. Customers join the system at a rate of λ i ; i = 1,2 using a Poisson process. We assumed that some customers maybe impatient due to the long waiting time in the queue and can leave the system without service or may switch from the longest queue to the shortest queue to reduce the waiting time. If the inventory levels of the items from the warehouse i at any time reaches below or reorder level s i , an order Q i = S i − s i > 0 ; i = 1,2 units is placed to bring the inventory level up to S i . The joint probability distribution of...Keywords
