Keywords: Assemble-to-order (ATO) Inventory Stochastic program Optimal policy Multi-dimensional newsvendor model a b s t r a c t In this paper we introduce a multi-stage stochastic program that provides a lower bound on the long-run average inventory cost of a general class of assemble-to-order (ATO) inventory systems. The stochastic program also motivates a replenishment policy for these syste...

The rapid improvement in the clinical manifestations of thiamine deficiency with thiamine supplementation is well known. To study this process in more detail, we rendered rats thiamine deficient either by dietary deprivation alone (DD) or, in addition, by daily pyrithiamine administration (DD + PT). We observed the cerebral metabolic and histological responses of these rats after 1 or 7 days of...

In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...

CPFR (Collaborative Planning Forecasting and Replenishment) has emerged as the latest business practice aiming to ensure that there is always enough quantity to meet consumer demand, while maintaining optimum levels of stock across the supply chain. The essence of CPFR is about utilizing technology capabilities and information sharing to support trading partner interaction and collaboration in ...

Local groundwater in coastal aquifers in Shenzhen has experienced heavy pumping since the 1980’s when Shenzhen began to expand very quickly from a fishing village to a modern city but lacked a public water supply. Meanwhile, large-scale land reclamation was carried out to meet the needs of various urbanization projects. In this paper we analyzed groundwater from a coastal aquifer system in Shen...

In this paper, an incentive scheme based on crashing lead time is proposed to coordinate a supplier-retailer supply chain (SC). In the investigated SC, the supplier applies a lot-for-lot replenishment policy to replenish its stock and determines the replenishment multiplier. Moreover, the transportation lead time is considered under the control of the supplier. The retailer as downstream member...

BACKGROUND Most groundwater conservation and management efforts focus on protecting groundwater for drinking water and for other human uses with little understanding or focus on the ecosystems that depend on groundwater. However, groundwater plays an integral role in sustaining certain types of aquatic, terrestrial and coastal ecosystems, and their associated landscapes. Our aim was to illumina...

Keywords: Climate impacts Groundwater hydrology Infiltration Water supply Isotopes s u m m a r y High elevation groundwater basins in the western United States are facing changes in the amount and timing of snowmelt due to climate change. The objective of this study is to examine seasonal variability in a high elevation aquifer (Martis Valley Watershed near Truckee, CA) by analyzing (1) tritium...
