Inventory record inaccuracy deteriorates supply chain performance because it leads to ineffective replenishment decisions. Conducting cycle counts (i.e., periodic inventory auditing) is a common approach to correct inventory records. It is not clear, however, how inaccuracy at different locations affects supply chain performance and how an effective cycle-count program for a multi-stage supply ...

The multi-stage lot-sizing problem with production capacities (MLSP-PC) deals with a supply chain that consists of a manufacturer with stationary production capacity and intermediaries (distribution centers or wholesalers) and a retailer to face deterministic demand. An optimal supply chain plan for the MLSP-PC specifies when and how many units each organization of the supply chain has to produ...

in this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. single supplier via a flexible flow line production system (ffl) produces several items and delivers them directly to an assembly facility. based on basic period (bp) strategy, a new mixed zero-one nonlinear programming model has been develope...

An important observation in supply chain management, known as the bullwhip eeect, suggests that demand variability increases as one moves up a supply chain. In this paper we quantify this eeect for simple, two-stage, supply chains consisting of a single retailer and a single manufacturer. Our model includes two of the factors commonly assumed to cause the bullwhip eeect: demand forecasting and ...
