In this paper, we studied single-server models of queuing-inventory systems (QIS) with
catastrophes in the warehouse part and negative customers (n-customers) in service facility …

A queueing-inventory system where the server is subject to breakdown is examined. The
products in inventory are provided by production. Two different types of customers are …

This article discusses a finite-source stock-dependent stochastic inventory system with
multiple servers and a retrial facility. The system can store a maximum of S items, and the …

Models of double-source queuing-inventory systems are studied in the presence of a finite
buffer for waiting in the queue of consumer customers, where instant destruction of inventory …

We study a production-inventory system with two customer classes with different priorities
which are admitted to the system following a flexible admission control scheme. The …

We discuss two queueing-inventory systems with catastrophes in the warehouse.
Catastrophes occur according to the Poisson process and instantly destroy all items in the …

Abstract Three-dimensional (3D) food printing is an emerging trend in additive
manufacturing and rapid prototyping. Based on a real-world scenario originating from 3D …

A hybrid replenishment policy in double sources queuing-inventory system with MAP flow of
consumer customers is proposed. The service time of the consumer customer has a phase …

The use of individual calving pens in modern farming is widely recognized as a good
practice for promoting good animal welfare during parturition. However, determining the …

A model of a single-server queuing-inventory system (QIS) with a limited waiting buffer for
consumer customers (c-customers) and catastrophes has been developed. When a …
