Abstract :
The majority of the studies on the integrated vendor-buyer inventory problem
assume that the shipments are equal. In this paper, shipments are considered to be nonequal.
Both demand and delivery times are also assumed to be stochastic. Moreover,
unsatised demand can be backordered and lost, and a service level constraint is considered.
The objective is to minimize both buyer and vendor costs at the same time. The problem
is solved by an exact heuristic algorithm. To validate performance of the algorithm, the
results are compared with those of the LINGO solver. Finally, a set of numerical problems
are applied to compare the results in the integrated and independent forms.
