Developing a closed-form cost expression for an (R,s,nQ) policy where the demand process is compound generalized Erlang.

Abstract

We derive a closed-form cost expression for an (R,s,nQ) inventory control policy where all replenishment orders have a constant lead-time, unfilled demand is backlogged and inter-arrival times of order requests are generalized Erlang distributedInventory control; Compound renewal process; Generalized Erlang distribution;
