Article
This paper introduces the Two-Echelon Inventory-Routing Problem with Fleet Management. This problem arises under a two-echelon vendor-managed inventory system when a company must make vehicle routing and inventory management decisions, while renting a fleet subject to short- and mid-term agreements. Different chemical products are transported conta...

O tratamento de efluentes domésticos e industriais é um processo complexo que ocorre empregando-se uma combinação de intervenções químicas, físicas e biológicas. Já a inteligência artificial (IA) consiste de diferentes métodos computacionais que visam simular os processos cognitivos dos seres humanos tais como a aprendizagem, o reconhecimento de pa...

This paper introduces the Two-Echelon Production-Routing Problem. This problem is motivated from the petrochemical industry, enlarging the supply chain integration by taking into account production, inventory, and routing decisions in a two-echelon vendor-managed inventory system. We describe, model, and design a branch-and-cut (B&C) to solve the p...

In the Brazilian judiciary, the Electoral Registry Offices (EROs) are responsible for managing the Brazilian electoral districts. Moreover, not only do they organize elections in their district, but they are also responsible for managing the registration of electors and supervising the political parties. Brazil has a multi-party system with more th...
Article
In this paper, we address multiple container loading problems, consisting of placing rectangular boxes, orthogonally and without overlapping, inside containers in order to optimize a given objective function, generally maximizing the value of the packed boxes or minimizing the number of containers required to pack all available boxes. Four techniqu...
Article
This paper explores how the consideration of two important practical aspects related to transportation in the forestry industry, wood moisture content and seasonal limitations on the maximal truck’s payload, may lead to savings in procurement costs. To this end, it proposes a multi-period mathematical formu- lation that decides on the location of p...

This paper describes a variant of the Periodic Capacitated Arc Routing Problem for inspections in a railroad network. Inspections are performed by vehicles over a time horizon on which some stretches need evaluation more frequently than others due to its use. Each car can evaluate one stretch per day without being attached to a depot; at each day,...
Article
This paper considers a dynamic scheduling problem where the set of jobs to perform is modified by the arrival of events (customer orders) requiring the execution of a new job or the cancellation of a previously ordered one once the production has begun. To tackle this dynamic context, we propose an online approach that reconsiders the actual schedu...

In warehouse operations management, picking is one of the most expensive and time-consuming activities; its impact can be seen in the final product delivered to clients, affecting logistic Key Performance Indicators and level of service. On the other hand, changes in picking policy and quality control are challenging to implement in a real-world co...
Article
This paper deals with a dynamic scheduling problem where a production schedule must be adapted to cope with the arrival of new orders. The problem encompasses several identical parallel machines with sequence-dependent setup times and a release date for each job. The problem’s goal is to minimize both the makespan and the total tardiness of the job...

The management of communication within a project can be considered as important as any other system within an organization because communication transmits and connects ideas, concepts, experiences and information on a project. This article describes an investigation of the problems in communication encountered by project managers in companies of di...
Chapter
Despite recent advances in both heuristic and implicit enumeration methods, exploring the whole solution space for large scaled problems remains, in most of practical cases, intractable. Indeed, enumeration and heuristic methods share their ability to thoroughly explore limited regions of the solution space. However, for different reasons they both...

The Canadian forestry industry plays an important role for the country's economy. In order to overcome economic challenges, and continue evolving its results, the rational use of resources in forestry products supply chain is required. We propose in this paper a mixed integer programming model describing the wood fibre network procurement of the su...
Article
This paper proposes a hybrid algorithm to tackle a real-world problem arising in the context of pulp and paper production. This situation is modelled as a production problem where one has to decide which wood will be used by each available processing unit (wood cooker) in order to minimize the variance of wood densities within each cooker for each...

This paper analyzes the role of the state as an agent of influence to the qualities’ strategies of Brazilian software companies. From the data collected between the years 1995-2009, we conducted a quantitative and descriptive longitudinal study on 2,229 software companies. From the perspective of Agency Theory and of Transaction Cost Theory, there...
Article
Managing a portfolio of customers of telecommunications equipment has several challenges, including the sales of the equipment itself, winning the contract for maintenance, but it is also to maintain the agreed level of service for this contract and give the customer required value to post-sale management. The primary objective of this paper is two...

Para atender a este propósito, foi realizada...
Article
We introduce a variable depth search branching, an extension to the local branching for solving Mixed- Integer Programs. Two strategies are assessed, a best improvement strategy and a first improvement strategy. The extensive computational assessment evidences a significant improvement over the local branching for both strategies.
Article
Kraft pulp, the raw material in paper manufacturing, is obtained by exposing pieces of wood to a cooking process. The parameters of this process (temperatures, times, chemicals, etc.) depend strongly on the density of the different woods in the cooker and have an influence oil the quality Of the pulp that is obtained. In order to optimize both the...
