Abstract Throughout its history, Operational Research has evolved to include methods,
models and algorithms that have been applied to a wide range of contexts. This …

Retailers are increasingly promising a maximum fulfillment time window for fulfilling
customer orders. Motivated by such guarantees, we consider an infinite-horizon periodic …

Fixed costs of ordering items or setting up a production process arise in many real‐life
scenarios. In their presence, the most widely used ordering policy in the stochastic inventory …

Prior research on inventory control has been wide ranging, yet the environmental
implications of an (s, S) inventory policy remain uninvestigated. This paper seeks to bridge …

In the digital age, operations can be improved by a wise use of information and
technological tools. During the COVID-19 pandemic, governments faced various choices of …

In this article, we investigate the dynamic control problem of a production-inventory system.
Here, demands arrive at the production unit according to a Poisson process and are …

This paper aims to find dynamic inventory policies for retailers that have limited knowledge
about future demand and sequentially observe the unprecedented demand data. We …

We consider continuous-review, single-product inventory systems with a constant
replenishment rate, Lévy demand, general inventory holding cost, and general lost-sales …

We consider a periodic review single‐item inventory model under stochastic demand. Every
m periods, in the regular order period, fixed order costs are K. In the periods in‐between, the …

This paper studies production-and-order strategies under three production systems in which
the supplier's production quantity is constrained by the upfront preparations of capacity due …
