Purpose This study focuses on a specific method of meat production that involves carcass purchase and by packing facilities with novel two-stage model simultaneously considers location-routing inventory-production operating decisions. The considered problem aims to reduce variable fixed transportation costs, inventory holding cost the opening cold storage facilities. Design/methodology/approach...

We study a supply chain consisting of production-inventory systems at several locations which are coupled by common supplier. Demand customers arrives each production system according to Poisson process and is lost if the local inventory depleted ("lost sales"). To satisfy customer's demand server needs raw material from associated inventory. The supplier manufactures replenish inventories, con...

We present a time decomposition for inventory routing problems. The methodology is based on valuing inventory with a concave piecewise linear function and then combining solutions to single-period subproblems using dynamic programming techniques. Computational experiments show that the resulting value function accurately captures the inventory’s value, and solving the multi-period problem as a ...

The single-vehicle cyclic inventory routing problem (SV-CIRP) is concerned with a repeated distribution of a product from a single depot to a selected subset of retailers having stable demands. The objective is to determine the subset of retailers to cyclically replenish, the quantities to be delivered to each, and to design the vehicle routes so that the expected total distribution and invento...

This paper focuses on optimizing the long- and short-term planning of perishable product supply chain network (PPSCN). It addresses integration strategic location, tactical inventory, operational routing decisions. Additionally, it takes into consideration specific characteristics products, including their shelf life, inventory management, transportation damages. The main objective is to minimi...

Dell’s supply chain for desktops involves Asian vendors shipping components by sea to several U.S. plants. While suppliers are responsible for shipping enough inventory, Dell can re-route and expedite their shipments while in transit and also transfer on-hand inventory in order to balance supply across sites. This paper describes the development, implementation and impact of the process and opt...

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...
