Modelling and analysis of inventory management systems in healthcare: A review and reflections

E Saha, PK Ray - Computers & Industrial Engineering, 2019 - Elsevier
Inventory management in a healthcare system needs to be compatible with its operations
and critical characteristics ensuring minimization of inventory-related cost as well as …

Adaptive inventory replenishment using structured reinforcement learning by exploiting a policy structure

H Park, DG Choi, D Min - International Journal of Production Economics, 2023 - Elsevier
We consider an inventory replenishment problem with unknown and non-stationary
demand. We design a structured reinforcement learning algorithm that efficiently adapts the …

Dual sourcing under non-stationary demand and partial observability

H Yee, HE van Staden, RN Boute - European Journal of Operational …, 2024 - Elsevier
We study dual sourcing under stochastic and non-stationary demand. The non-stationarity is
modeled through Markov-modulated changes in the underlying demand distribution. The …

Optimal trade execution in illiquid markets

E Bayraktar, M Ludkovski - Mathematical Finance: An …, 2011 - Wiley Online Library
We study optimal trade execution strategies in financial markets with discrete order flow. The
agent has a finite liquidation horizon and must minimize price impact given a random …

[HTML][HTML] Optimal control of production-inventory systems with correlated demand inter-arrival and processing times

NM Dizbin, B Tan - International Journal of Production Economics, 2020 - Elsevier
We consider the production control problem of a production-inventory system with correlated
demand inter-arrival and processing times that are modeled as Markovian Arrival …

Stock out analysis: An empirical study on forecasting, re-order point and safety stock level at PT Combiphar, Indonesia

C Mekel, SPD Anantadjaya… - RIBER: Review of …, 2014 - papers.ssrn.com
Inventory is one of the most important assets in the companies, especially in manufacturing
company. In the event of problems related to inventory, the company's business processes …

Bayesian quickest detection in sensor arrays

M Ludkovski - Sequential Analysis, 2012 - Taylor & Francis
We study Bayesian quickest detection problems with sensor arrays. An underlying signal is
assumed to gradually propagate through a network of several sensors, triggering a cascade …

Structural results for average‐cost inventory models with Markov‐modulated demand and partial information

H Avci, K Gokbayrak, E Nadar - Production and Operations …, 2020 - journals.sagepub.com
We consider a discrete‐time infinite‐horizon inventory system with non‐stationary demand,
full backlogging, and deterministic replenishment lead time. Demand arrives according to a …

A hidden Markov model to detect on-shelf out-of-stocks using point-of-sale data

R Montoya, C Gonzalez - Manufacturing & Service …, 2019 - pubsonline.informs.org
We propose a hidden Markov model (HMM) approach to identifying on-shelf out-of-stock
(OOS) by detecting changes in sales patterns resulting from unobserved states of the shelf …

[HTML][HTML] Data-driven control of a production system by using marking-dependent threshold policy

S Khayyati, B Tan - International Journal of Production Economics, 2020 - Elsevier
As increasingly more shop-floor data becomes available, the performance of a production
system can be improved by developing effective data-driven control methods that utilize this …
