This paper analyses a discrete-time (s, S) queueing inventory model with service time and back-order in inventory. The arrival of customers is assumed to be the Bernoulli process. Service follows geometric distribution. As soon as level reaches pre-assigned due demands, an order for replenishment placed. Replenishment also When reduces zero or non-replenishment items, maximum k are allowed syst...

Abstract The peculiarity of renewable sources is their replenishment. To ensure energy security and correctly use land resources, it possible to biogas plants, which are sources. However, efficient these installations turns out be a difficult task that requires comprehensive assessment the parameters operation. In example under consideration, such are: choice power heating equipment installatio...

AIMS Glycosaminoglycan (GAG) layer replenishment is a cornerstone in the therapy of interstitial cystitis (IC). During the last years intravesical GAG layer replenishment has proven to be an effective treatment for overactive bladder (OAB), radiation cystitis, and recurrent urinary tract infections (UTIs). METHODS Examination of different substances available for intravesical GAG replenishmen...

For many industries (e.g., apparel retailing) managing demand through price adjustments is often the only tool left to companies once the replenishment decisions are made. A significant amount of demand uncertainty can be resolved using the early sales information. In this study, a Bayesian approach is used to summarize sales information and pricing history in an efficient way which then feeds ...

This contribution is concerned with the value of RFID for retail store operations, particularly the use of the technology to automate shelf replenishment decisions. We construct and test an inventory control policy based on RFID data with case-level tagging. Our model incorporates RFID hardware capable of detecting bidirectional product movements between a store's backroom and the sales floor. ...

To review clinical manifestations and genetic features of the autoinflammatory diseases, a group of rare, genetically defined diseases which have been newly grouped into a coherent whole. We performed a literature review using the keywords 'periodic fever syndrome', 'autoinflammatory disease' and 'therapy'. All relevant original and review articles in English were reviewed. A case report of eac...

This study presents a new integrated production–inventory policy under a finite planning horizon and a linear trend in demand. We assume that the vendor makes a single product and supplies it to a buyer with a non-periodic and just-in-time (JIT) replenishment policy in a supply chain environment. The objective is to minimize the joint total costs incurred by the vendor and the buyer. In this st...

Although vesicle replenishment is critical in maintaining exo-endocytosis recycling, the underlying mechanisms are not well understood. Previous studies have shown that both rapid and slow endocytosis recycle into a very large recycling pool instead of within the readily releasable pool (RRP), and the time course of RRP replenishment is slowed down by more intense stimulation. This finding cont...
