Abstract: We deal with a two component demand rate inventory system that is composed of two arrival patterns of customers known as homogeneous and non-homogeneous arrival patterns. The homogeneous arrival pattern occurs at zero inventory and the arriving customer compulsorily enters into an infinite orbit. But at the time of positive inventory, the non-homogeneous arrival pattern occurs at a rate which depends on the present stock level (PSL). We set a classical retrial policy (CRP) for an orbital demand and (s, Q) ordering policy to fix for any reorder. In this model, Laplace-Stieltjes transform (LST) is used to investigate the waiting time of a retrial demand under the stability condition and all the necessary system characteristics are measured using a matrix-geometric approach and further the sufficient numerical tabulations and illustrations are detailed to explore the suitability of the proposed model.

Keywords: stock-dependent; retrial queue; waiting time; lead time.
