Certain inventory items are living organisms, for example livestock, and are therefore capable of growing during the replenishment cycle. These items often serve as various saleable food items downstream in supply chains. The purpose of this paper is to develop a lot sizing model for growing items if the supplier of the items offers incremental quantity discounts. A mathematical model is derive...

The purpose of this article is to model and solve an integrated location, routing and inventory problem (LRIP) in cash-in-transit (CIT) sector. In real operation of cash transportation, to decrease total cost and to reduce risk of robbery of such high-value commodity. There must be substantial variation, making problem difficult to formulate. In this paper, to better fit real life applications ...

Recent studies have shown that environmental energy harvesting technologies have the potential to provide perpetual operation to rechargeable sensor networks. However, due to the large variations of the ambient energy source, such networks could only support low-rate data services and their performance is influenced by numerous unpredictable environmental factors. In order to bridge this gap to...

We propose a robust optimization approach to address a multi-period, inventory control problem under ambiguous demands, that is, only limited information of the demand distributions such as mean, support and some measures of deviations. Our framework extends to correlated demands and is developed around a factor-based model, which has the ability to incorporate business factors as well as time ...

Multiple synaptic vesicle (SV) retrieval modes exist in central nerve terminals to maintain a continual supply of SVs for neurotransmission. Two such modes are clathrin-mediated endocytosis (CME), which is dominant during mild neuronal activity, and activity-dependent bulk endocytosis (ADBE), which is dominant during intense neuronal activity. However, little is known about how activation of th...

This paper focuses on stock replenishment and shipment scheduling with deteriorating item for vendor-managed inventory systems. In consideration that demand process follows a typical Poisson process, hybrid replenishment and dispatching model with correction for VMI is proposed, and a combined solving approach named OSJCA is presented. As approximation of expected dispatching number per repleni...

This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...
