Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to develop an efficient optimization model to determine storage strategies for water supply purpose in multi-reservoir systems. The specific goals in designing a multi-reservoir system for water supply purpose is to optimize the reservoir sizes and configurations to satisfy demands for water supply at the minimum cost. Four models are developed to optimize the configuration of multi-reservoir systems for water supply purposes. These models apply optimal control theory (OCT) and penalty successive linear programming (PSLP) as the most promising techniques to optimize large and complex water resources systems. Three of these models are based on the OCT. They have, however, different approaches to join the cost function to other objectives. The fourth model employs a new composite optimization algorithm, which is introduced in this study. This is called PSLP-OCT model and consists of two OCT and PSLP modules. These two modules interactively share their results during the optimization iterations. Multi-objective programming methods are implemented in the four models in order to consider the two non-commensurate objectives of minimizing cost and water deficit. The weighting and epsilon constraint methods are used as the most suitable generating techniques to incorporate the problem objectives. The comparative performances of the design models on several case studies showed that the design models based on the OCT algorithm fail to design the multi-reservoir system optimally. However, The PSLP-OCT performance indicated that it is a very promising optimization method to design multi-reservoir systems regardless of their size. The PSLP-OCT model is the first model of its type that applies the proposed composite algorithm and incorporates multi-objective programming into the multi-reservoir design problems. Due to the inherent characteristics of the optimal control theory, the control variables in the OCT, module is not sensitive to the initial solution. The model structure is adapted such that the PSLP module is independent of the design period length. Therefore, using large hydrologic data does not affect its problem dimension.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides essential background knowledge on the development of model-based real-world solutions in the field of control and decision making for water systems. It presents system engineering methods for modelling surface water and groundwater resources as well as water transportation systems (rivers, channels and pipelines). The models in turn provide information on both the water quantity (flow rates, water levels) of surface water and groundwater and on water quality. In addition, methods for modelling and predicting water demand are described. Sample applications of the models are presented, such as a water allocation decision support system for semi-arid regions, a multiple-criteria control model for run-of-river hydropower plants, and a supply network simulation for public services.

Available in PDF, EPUB and Kindle. Book excerpt: Water supply system planning is concerned about the design of water supply infrastructure for distributing water from sources to users. Population growth, economic development and diminishing freshwater supplies are posing growing challenges for water supply system planning in many urban areas. Besides the need to exploit alternative water sources to the conventional surface and groundwater supplies, such as reclaimed water, a systematic point of view has to be taken for the efficient management of all potential water resources, so that issues of water supply, storage, treatment and reuse are not considered separately, but rather in the context of their interactions. The focus of this dissertation is to develop mathematical models and optimization algorithms for water supply system planning, where the interaction of different system components is explicitly considered. A deterministic nonlinear programming model is proposed at first to decide pipe and pump sizes in a regional water supply system for satisfying given potable and non-potable user demands over a certain planning horizon. A branch-and-bound algorithm based on the reformulation-linearization technique is then developed for solving the model to global optimality. To handle uncertainty in the planning process, a stochastic programming (SP) model and a robust optimization (RO) model are successively proposed to deal with random water supply and demand and the risk of facility failure, respectively. Both models attempt to make the decision of building some additional treatment and recharge facilities for recycling wastewater on-the-site. While the objective of the SP model is to minimize the total system design and expected operation cost, the RO model tries to achieve a favorable trade-off between system cost and system robustness, where the system robustness is defined in terms of meeting given user demands against the worst-case failure mode. The Benders decomposition method is then applied for solving both models by exploiting their special structure.

Book excerpt: The increasing pressure from energy and environmental protection has made the research for sustainable electrical energy urgent. The integration of high-proportion renewable energy resources offers significant achievements for decreased carbon emissions and increased economic costs. This calls for new concepts of modelling, monitoring, planning, optimization, control, etc. Due to the complexity of electrical energy systems (EES), it is challenging to design effective and smart solutions. The emerging digital technologies may provide promising solutions owing to the successful development of artificial intelligence, blockchain, edge computing, 5g/6g, etc. Moreover, digital technologies facilitate the integration of cyber and physical systems, which further benefits the intelligent detection, coordination, and management of EESs. There are many challenges that require further research and development on policy, architecture, modelling, planning, operation, optimization, and control for sustainable EESs.

This book was released on 2019-09-20 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization is considered as a decision-making process for getting the most out of available resources for the best attainable results. Many real-world problems are multi-objective or multi-attribute problems that naturally involve several competing objectives that need to be optimized simultaneously, while respecting some constraints or involving selection among feasible discrete alternatives. In this Reprint of the Special Issue, 19 research papers co-authored by 88 researchers from 14 different countries explore aspects of multi-objective or multi-attribute modeling and optimization in crisp or uncertain environments by suggesting multiple-attribute decision-making (MADM) and multi-objective decision-making (MODM) approaches. The papers elaborate upon the approaches of state-of-the-art case studies in selected areas of applications related to sustainable development decision aiding in engineering and management, including construction, transportation, infrastructure development, production, and organization management.
