In this paper we propose a new discrete time discrete state inventory model for perishable items of a single product. Items in stock are assumed to belong to one of a finite number of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre-perishable quality. By the end of each epoch, items in each inventory class either stay in ...

In this paper we analyze the optimal joint decisions of when, how and howmuch to replenish customers with products of varying ages. We discuss the main features of the problem arising in the joint replenishment and delivery of perishable products, and we model them under general assumptions. We then solve the problem by means of an exact branch-and-cut algorithm, and we test its performance on ...

This paper studies a perishable inventory model, which assumes that each perishable item has finite lifetime, and only one item is consumed each time. The lifetimes of perishable items are independent random variables with the general distribution and so are the consumption internal. Under this assumption, by using backward equations and limit distribution of Markov skeleton processes, this pap...

Persediaan adalah sumber daya menganggur yang menunggu untuk diproses lebih lanjut. bahan baku memiliki waktu penggunaan terbatas. Keterbatasan ini disebabkan pertimbangan kerusakan barang. Produk perishable produk dengan beberapa ciri khusus membuat persediaannya berbeda jenis lainnya. Untuk industri pengolahan makanan, kadaluarsa merupakan masalah harus diperhatikan. Selain berdampak pada kes...

Qishta is a popular Middle Eastern coagulated cream product, prepared using a traditional heating and skimming process. This study in Lebanon aimed to assess the microbiological and chemical profile of the product. Samples selected from 31 different manufacturers and outlets were analysed using standard methods. The plate counts for the various microorganisms were either of borderline acceptabi...

Abstract Assume that customers are price sensitive, changes in the price of perishable products will bring changes in demand, and business can adjust the perishable products' price to influence the market demand, a perishable products multi-stage pricing model considering cancelations and no-shows is proposed, and the optimal pricing, the optimal expected revenue with the products' initial quan...

In this study, a two echelons supply chain system in which a supplier is producing perishable product and distribute it to multiple customers is considered. By allowing lateral transshipment mechanism, it is also possible to deliver products to some customers in some periods in bulk, then customers using their own vehicle to transship goods between each other seeking further reduction in the ov...

In this work, we investigate the value of information when the decision-maker knows whether a perishable product will be in high, moderate or low demand before placing his order. We derive optimality conditions for the probability of the baseline scenario under symmetric distributions and analyze the impact of the cost parameters on simulation experiments. Our results provide managers with deep...
