1. Heuristics for the optimized deployment of small cells in next-generation networks
Abstract Heterogeneous Networks (HetNets) have been introduced as an alternative means of improving the overall network capacity. However, HetNets increase the complexity and cost of transport due to the large number of smallcells (SCs) that have to be connected, and hence, it is essential to investigate the best way to plan the joint deployment of radio and

2. MATHEMATICAL MODELLING AND SOLUTION APPROACHES FOR PRODUCTION PLANNING IN A CHEMICAL INDUSTRY
ABSTRACT This paper addresses a lot sizing problem in a Brazilian chemical industry where a product can be produced by more than one process, which can use different parallel machines and may even consume a wide range of raw materials. Moreover, most of the products are liquids and the inventories must be kept in a restricted number of storage tanks with a l

3. MULTI-VEHICLE COVERING TOUR PROBLEM: BUILDING ROUTES FOR URBAN PATROLLING
ABSTRACT In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to

4. Metaheurística para o Problema de Planejamento de Redes de Transmissão de Energia Elétrica com Redimensionamento / Metaheuristics for the transmission expansion planning problem with redesign
At times, the electrical load in dierent areas varies, claiming the construction of new electric generators and the expansion of the electrical transmission network. In this dissertation we focus on the transmission expansion planning problem, assuming that new generators are built to meet the new demands. This expansion requires large investments, which nee

5. Simulação multiagentes aplicada ao planejamento da produção florestal sustentável / Multi-agent simulation applied to the planning of the sustainable forest production
O presente trabalho objetivou avaliar a aplicação do paradigma da Inteligência Artificial Distribuída em problemas de manejo florestal. Para isso, foram desenvolvidos dois Sistemas Multiagentes: um para o planejamento de longo prazo de um empreendimento florestal (i) e outro para seqüenciamento da colheita no intervalo de um ano (ii). Para o SMA i, fora

6. Heuristic for solving capacitor allocation problems in electric energy radial distribution networks
The goal of the capacitor allocation problem in radial distribution networks is to minimize technical losses with consequential positive impacts on economic and environmental areas. The main objective is to define the size and location of the capacitors while considering load variations in a given horizon. The mathematical formulation for this planning probl

7. Uma abordagem multi-agente para competição de agentes negociadores em gerenciamento de cadeias de suprimento. / A multi-agent approach to negotiating agents of competition in supply chain management.
This work aimed to design a computational approach to supply chain management problem in the scenario Trading Agent Competition for Supply Chain (TAC-SCM) when disturbances on manufacturing process are considered. Simulations have shown that the decentralized approach based on smart products is promising in terms of robustness of the system of control and pl

8. Integrated planning of optical networks - optimization and protection in virtual and physical topologies / Planejamento integrado de redes óticas - otimizção e proteção nas topologias virtual e física
This work aims to design integrated optical networking, which in the literature, due to complexity, is divided into Virtual Topology Design (VTD) and Physical Topology Design (PTD). Linear programming and heuristics are proposed to maximize the utilization of the network, so that for future demands, the same network may remain able to meet the requests, with

9. HEURISTICS FOR DATA WAREHOUSE REQUIREMENTS ELICITATION USING PERFORMANCE INDICATORS / HEURÍSTICAS PARA IDENTIFICAÇÃO DE REQUISITOS DE DATA WAREHOUSE A PARTIR DE INDICADORES DE DESEMPENHO
Organizations need to change and evolve, but for that it is necessary to make the right decisions. For this decision, companies are using Information Technology (IT) as a fundamental part to support their decisions. An essential IT component to improve the process of decision making is the data warehouse. In order to fulfill its role well, the data warehouse

10. Propose one method of resource levelling developed using the principles of the theory of constraints to operational planning. / Proposição de um método de nivelamento de recursos a partir de princípios da teoria das restrições para o planejamento operacional.
The planning process of construction of vertical housings used in Brazil have shown lacks, mainly when confronting the scheduling guiding the decision-making to invest, concerning the risk of the enterprise, versus the results obtained during the execution control. The discrepancies observed between the expected results regarding scheduling and those observe

12. Hybrid heuristic strategies for planning and scheduling forest harvest and transportation activities in short term / Estrategias hibridas para um problema de planejamento e escalonamento de atividades florestais em curto prazo
This thesis aimed at studying and solving a planning and scheduling problem stemming from forest harvest and wood transportation activities. Our approach treated a real problem faced by large pulp and paper companies in Brazil. It consists in planning, for a short-term horizon, the harvesting operations in different forest areas and the transportation of the
