The German Armed Forces provide an operation contingent to support the North Atlantic Treaty Organization (NATO) Response Force (NRF). To fulfill a mission, NRF operates number of technical systems, mostly vehicles. Each system is composed several parts which might fail over time, and it can only be used again in mission if all broken are replaced. For short deployments (e.g., one month), troop...

O objetivo deste estudo é desenvolver uma solução para o problema de distribuição proposto pelos jogos matemáticos 2017-2018, organizado conjuntamente pela Federação Francesa Jogos Matemáticos e Empresa Modelagem Matemática. Conhecido na literatura como um produção-estoque-distribuição-roteamento (PIDRP), este otimização combinatória NP-difícil, ainda pouco explorado literatura. Esta pesquisa b...

We study a perishable inventory system that requires to maintain a fresh and large quantity of inventory at all times. For example, certain pharmaceuticals are kept for emergency preparedness and response operations. We aim to maximize the profit by optimizing the joint problem of the ordering and issuing policies while maintaining a minimum amount of perishable inventory. First, we consider a ...

A firm is considered that manages its internal manufacturing operations according to a just-in-time system, but maintains an inventory of finished goods as a buffer against random demands from external customers. The finished goods inventory may be analysed by the methods of classical inventory theory in order to characterize the trade-off between inventory costs and schedule stability. A model...

Solving the Inventory Location-Routing Problem can been seen as an approach to optimize both a supply chain design and its operations costs. Assumptions consider that vehicles might visit more than one retailer per route and that inventory management decisions are included for a multi-depot, multi-retailer system with storage capacity over a discrete time planning horizon. The problem is to det...

In this paper, we study a logistics network design problem with vendor managed inventory in which the company is in charge of managing inventory for its downstream warehouses and retailers, and can choose whether to satisfy each retailer’s demand. The problem incorporates the location, transportation, pricing, and warehouse-retailer echelon inventory replenishment decisions. Traditionally, thes...

This paper considers a problem of integrated decision-making for job scheduling and delivery batching wherein different inventory holding costs between production and delivery stages are allowed. In the problem, jobs are processed on a facility at a production stage and then delivered at the subsequent delivery stage by a capacitated vehicle. The objective is to find the coordinated schedule of...

In this paper, we study the distribution network design problem integrating transportation and infinite horizon multiechelon inventory cost function. We consider the trade-off between inventory cost, direct shipment cost, and facility location cost in such a system. The problem is to determine how many warehouses to set up, where to locate them, how to serve the retailers using these warehouses...
