1. ASSESSING COMPETITION IN BRAZIL’S ELECTRICITY MARKET IF BID-BASED DISPATCH WERE ADOPTED
RESUMO Simuladores de mercado, considerando características estruturais, são ferramentas úteis para a realização de análise concorrencial ex-ante de mudanças fundamentais no mercado, tais como: liberalização de mercado, fusões e aquisições, desinvestimentos e reformas regulatórias. Nesse artigo, simulações Cournot-Nash são utilizadas para ava

2. THE USE OF SIMULATION TO MODEL THE DISPATCH OF INBOUND CONTAINERS IN PORT TERMINALS
ABSTRACT This paper describes a study of the dispatch planning/scheduling process for inbound containers handled with a reach stacker. Client container pickup is scheduled at least one day in advance for one of six two-hour time windows (six five-container-high stacks per time window) on a given day. A buffer area is available for the containers to be moved

3. Proposal for a Monitoring and Dispatch System for Distributed Micro-Generation of Renewable Energy in Virtual Energy Centers
ABSTRACT The creation and updating of ANEEL (National Electricity Regulatory Agency) regulatory resolution on distributed generation provided a new business environment for the electricity sector, as well as enabling consumers to generate energy. In this context, distributed microgeneration plants management is a challenge, mainly for electric power distribu

4. The impact of payload truck factor use in mine performance reports for an open pit copper mine in Brazil
Abstract This article aims to evaluate the use of a truck factor for off-highway trucks in open pit mine operations, thus reducing error on material movement and mine production data entry. This method is current for a copper mine located in South East Pará, Brazil. With a dispatch system, the truck factor is calculated using three data inputs called measur

5. BALANCING AMBULANCE CREW WORKLOADS VIA A TIERED DISPATCH POLICY
ABSTRACT Emergency Medical Services (EMS) system’s mission is to provide timely and effective treatment to anyone in need of urgent medical care throughout their jurisdiction. The default dispatch policy is to send the nearest ambulance to all medical emergencies and it is widely accepted by many EMS providers. However, sending nearest ambulance is not alw

6. DAILY SCHEDULING OF SMALL HYDRO POWER PLANTS DISPATCH WITH MODIFIED PARTICLES SWARM OPTIMIZATION
This paper presents a new approach for short-term hydro power scheduling of reservoirs using an algorithm-based Particle Swarm Optimization (PSO). PSO is a population-based algorithm designed to find good solutions to optimization problems, its characteristics have encouraged its adoption to tackle a variety of problems in different fields. In this paper the

7. Desenvolvimento de modelos e algoritmos sequenciais e paralelos para o planejamento da expansão de sistemas de transmissão de energia elétrica / Development of mathematical models, sequential and parallel algorithms for transmission expansion planning
The main objective of this study is to propose a new methodology to deal with the long-term transmission system expansion planning with multiple generation dispatch scenarios problem (TEP-MDG). With the methodology proposed in this thesis we aim to build expansion plans with minimum investment cost and also capable of meeting the new demands of modern electr

8. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

9. Despacho online para o problema dinâmico de roteamento de veículos
The allocation of vehicles for a specific customers demand is subject to a combinatorial explosion of possibilities by the exponential increase of alternatives according to growth of the problem size. When environmental changes are considered, such as the advent of new customers, the Vehicle Routing Problem becomes dynamic and even more complex and unpredict

11. Gerenciamento da oferta e da demanda em micro-sistemas de energia via otimização por enxames de partículas
Intelligent micro-grids, which integrate distributed energy resources with loads, are among the current major tendencies for electric power distribution systems. Distributed resources promote important changes in the operation and management of the distribution system, since they require that the control and the intelligence of the system must be distributed
