We consider an infinite horizon, continuous review inventory model
with deterministic stationary demand where the shelf life of the items
is uncertain. The initial life times of the incoming items from the supplier
is a discrete random variable. When the age of the items reaches
the initial shelf-life, a quality control test for which the outcome is
random is applied. According to the result of this test, it is possible
to use the items to satisfy demand for an additional time period. In
this environment, our objective is to investigate the supplier flexibility
which is modeled by including a return policy and the initial shelf life
information received before ordering decisions. Several scenarios are
constructed and compared using Renewal Theory.
