1. Using ELECTRE TRI to support maintenance of water distribution networks
Problems encountered in the context of the maintenance management of water supply are evidenced by the lack of decision support models which gives a manager overview of the system. This paper, therefore, develops a model that uses, in its framework, the multicriteria outranking method ELECTRE TRI. The objective is to sort the areas of water flow measurement

2. MODELO HIDRÁULICO BASEADO NO MÉTODO DAS CARACTERÍSTICAS E ALGORITMOS GENÉTICOS PARA OTIMIZAÇÃO DA OPERAÇÃO DE REDES DE ABASTECIMENTO DE ÁGUA E DE ESTAÇÕES DE BOMBEAMENTO
A hydraulic model was developed for simulation of water supply networks using the Method of Characteristics (MOC), introducing new features to the CALHIDREDMT model, proposed by Righetto (1994). The model uses the concept of pseudo-transient, using a fictitious value for the wave celerity. Simulations were performed in networks equipped with reservoirs, tank

3. Real-time optimization of water supply system operation / Otimização energética em tempo real da operação de sistemas de abastecimento de água
This work presents a computational model for real-time optimization of water-distribution networks operation. An integrated software tool has been developed which is composed of three main modules: (i) a hydraulic simulator that performs the extended period simulation of the system (EPANET); (ii) a short-term demand-forecasting model, based on the moving Fou

4. Otimização dos custos de energia elétrica na programação do armazenamento e distribuição de água em redes urbanas / Minimization of the electrical energy cost in water distribution networks
The problem focused in this study consists of reducing the eletrical energy cost necessary to the operation of hydraulic pumps. The hydraulic pumps are used to catch water from artesians wells or Water Treatment Station to supply tanks which are located in districts in a city, from which the population will be supplied by gravitational force. As the cost of

5. Operação otimizada do sistema adutor metropolitano utilizando algoritmos genéticos: estudo de caso - SAM Leste da Região Metropolitana de São Paulo (R.M.S.P.). / Optimized operation of metropolitan mains system using genetic algorithms: case study - East Metropolitan Mains System of Metropolitan Region of São Paulo (M.R.S.P.).
This work presentss an evaluation of optimization of real time operation of a complex water supply system. Genetic Algorithm associated with a SCADA system and a network hydraulic simulation model was applied. Observed historic consumptions were used as a perfect water demand forecast model. Case study is the optimization of a multiobjective function (energy
