In this paper, we consider the pricing and lot-sizing problem for a product subject to general rate of deterioration and partial backordering. We use impatience functions to model backlogging of demand. We show that even when lost sale and backorder costs are present, the problem is well posed in the reduced space. We provide an iterative procedure for solving the overall problem. We describe s...

We consider an M/M/1 queueing system with inventory under the (r,Q) policy and with lost sales, in which demands occur according to a Poisson process and service times are exponentially distributed. All arriving customers during stockout are lost. We derive the stationary distributions of the joint queue length (number of customers in the system) and on-hand inventory when lead times are random...

eXecutive summary Statistics show that on average, consumers are hesitant to try new dairy products, making it challenging for producers to introduce new offerings successfully. Helping turn this around, the intelligent shelf solution provides eye-catching digital graphic displays right next to products, which increases awareness of new products and encourages consumers to try them. The solutio...

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...

A 5-kbp region upstream of the are-ben-cat genes was cloned from Acinetobacter sp. strain ADP1, extending the supraoperonic cluster of catabolic genes to 30 kbp. Four open reading frames, salA, salR, salE, and salD, were identified from the nucleotide sequence. Reverse transcription-PCR studies suggested that these open reading frames are organized into two convergent transcription units, salAR...

We establish two previously undocumented patterns in the purchase selections of individual investors and confirm a related pattern. These patterns hinge on investors’ previous experience with a stock. We demonstrate that investors prefer to: (1) repurchase stocks they previously sold for a gain rather than stocks they previously sold for a loss, (2) repurchase stocks that have lost value subseq...

This paper develops a model for the closed-loop supply chain network design with disruption risk. By considering supply disruption, two factors including extra inventory and lateral transshipment are used as resilience strategies. The main purpose is to reduce the supply chain costs due to the location decisions, quantity of products between different levels and lost sale. Disruption in a suppl...

one of the traditions relied on by shī‘a jurists in jurisprudence and especially in the discourse on judgment and testimonies is the tradition or the story of imam ‘alī’s (a.s.) lost coat of mail. the coat of mail being found in the market while it had been put on sale by someone, the imam’s going to the judge, filing a lawsuit against that person, and providing evident proofs in the court hear...

In this paper we examine heterogeneity in the simultaneous space-time impact of foreclosures on neighborhood property values. The heterogeneity arises from foreclosed properties that experienced different types of foreclosure outcomes. We find that for foreclosures that are not observed to have concluded with a market sale, the negative price impacts begin while the foreclosing household still ...
