This paper deals with the determination of production-shipment policy for an integrated vendor-buyer system. The inventory model contains two decision variables: the replenishment lot size and the number of deliveries. This paper solves the inventory model considering two cases: 1) the replenishment lot size as continuous variable and the number of shipments as discrete variable, and 2) the rep...

Lot-size problems has drawn a great deal of attention in OR/Operations Management research literature. In their purest form, lot-size problems focus on the trade-off between set-up and inventory costs in generalized production environments. Single item lot-size problems are successfully treated through specialized Dynamic Programming algorithms [10, 12], while multi item problems prove harder t...

BACKGROUND Traditional Lot Quality Assurance Sampling (LQAS) designs assume observations are collected using simple random sampling. Alternatively, randomly sampling clusters of observations and then individuals within clusters reduces costs but decreases the precision of the classifications. In this paper, we develop a general framework for designing the cluster(C)-LQAS system and illustrate t...
