We study an inventory system with multiple supply sources and expediting options. The replenishment lead times from each supply source are stochastic, representing congestion and disruption. We construct a family of smart ordering and expediting policies that utilize real-time supply...

We consider the setting of a firm operating multiple warehouses and multiple stores where each warehouse is endowed with an initial non-replenishable inventory. There is a finite selling horizon and, at the beginning of each period, the firm needs to decide for each store how many units of...

We review the recent developments in dynamic inventory models with financial flow considerations. The focus is on the literature that introduces cash flow dynamics into the classic inventory models that do not explicitly consider the interactions between physical (or material) and financial...

We apply Multi-Agent Deep Reinforcement Learning (MADRL) to inventory management problems with multiple echelons and evaluate MADRL's performance to minimize the overall costs of a supply chain. We also examine whether the upfront-only information-sharing mechanism used in MADRL helps alleviate...

This chapter summarizes recent development on simple heuristics for optimal inventory policies of multi-echelon inventory systems. These simple heuristics are based on solving a sequence of single-stage inventory problems whose parameters are obtained from the original system data. We mainly...

Agents attempt to maximize expected profits earned by selling multiple units of a perishable product where their revenue streams are affected by the prices they quote as well as the distribution of other prices quoted in the market by other agents. We propose a model which captures this...

Operations Management endeavors to identify polices that improve real-world operating systems. However, these systems often consist of actors that do not behave fully rationally and to improve performance managers must predict how such boundedly-rational actors will behave. Approaches to this...

We estimate the effect of violent political conflicts on firm inventory purchase decisions using monthly data of 431 clients of a multinational beverage supplier in Mozambique. Firms decrease inventory purchases by up to 19% in response to conflicts occurring within a 10km radius. Small firms...

Problem definition: Supply chain complexity from multiple sources inhibits the accuracy of inventory recording that is critical for maintaining and improving operational efficiency. Using a proprietary panel data set comprising inventory, sales, and product attribute information, we explore how...
