Taylor Approximation of Inventory Policies for One-Warehouse, Multi-Retailer Systems with Demand Feature Information

Huang, Jingkai; Shang, Kevin; Yang, Yi; Zhou, Weihua - 2022

Motivated by Fresh Hema, we consider a distribution system in which retailers replenish perishable goods from a warehouse, which, in turn, replenishes from an outside source. Demand at each retailer depends on exogenous features and a random shock, and unfulfilled demand is lost. The objective...

Managing a Hybrid RDC-DC Inventory System

Wang, Tong; Yan, Xiaoyue; Yang, Chaolin - 2022

In this paper, we study a hybrid RDC-DC serial inventory system where the RDC replenishes its stock from an outside supplier, while the DC faces random demand and replenishes its stock from the RDC. However, unlike in the traditional serial system, the DC itself can replenish its inventory from...

Integrated procurement-production inventory model in supply chain : a systematic review

Utama, Dana Marsetiya; Santoso, Imam; Hendrawan, Yusuf; … - In: Operations research perspectives 9 (2022), pp. 1-21

Inventory affects the production process and supply chain activities. Integrated decision inventory improves performance and optimizes supply chain activities. However, its disadvantage is the Integrated Procurement Production (IPP) inventory model, which manages the raw material inventory in...

An opaque selling scheme to reduce shortage and wastage in perishable inventory systems

Sasanuma, Katsunobu; Hibiki, Akira; Sexton, Thomas R. - In: Operations research perspectives 9 (2022), pp. 1-12

Effective management of perishable inventory systems is often strewn with challenges, especially when a strong trade-off relationship exists between shortage and wastage of perishables: A smaller inventory increases the chance to lose sales (leading to higher expected shortage cost), while a...

Optimal Ordering Policy for TwoProduct Inventory Models with Fixed Ordering Costs

Li, Yu; Sethi, Suresh - 2022

We study the problem of finding an optimal ordering policy that minimizes the present value of the costs incurred over the infinite horizon in a continuous-time two-products inventory model with fixed setup costs, unit production costs, and linear holding and backlog costs. We first consider a...

Optimal Dual-Sourcing Policies for Backlogging and Lost-sales Inventory Systems with Uncertain Lead Times and Order Tracking

Song, Jing-Sheng Jeannette; Xiao, Li; Zhang, Hanqin - 2022

This paper studies how companies use order-tracking information to more effectively execute their dual-sourcing strategies. We consider dual-sourcing inventory systems under either backlogging or lost-sales assumptions. The normal source consists of a two-stage tandem queue with Erlang...

Distributionally Robust Inventory Management with Advance Purchase Contracts

Xue, Yilin; Li, Yongzhen; Rujeerapaiboon, Napat - 2022

We propose a distributionally robust inventory model for finding an optimal ordering policy that attains the minimum worst-case expected total cost. In a classical stochastic setting, this problem is typically addressed by dynamic programming and is solved by the famous base-stock policy. This...
