Every morning, water suppliers need to define their pump schedules for the next 24 h drinking production. Plans must be designed in such a way that is always available and amount of unused pumped into network reduced. Therefore, operators accurately estimate day’s consumption profile. In real-life applications with standard profiles, some expert system or vector autoregressive models are used. Still, recent years, significant improvements time series prediction have been achieved through special deep learning algorithms called long short-term memory (LSTM) networks. This paper investigates applicability LSTM demand optimal control compares LSTMs against other methods currently used by suppliers. It shown outperform since they can easily integrate additional information like day week national holidays. Furthermore, online- transfer-learning capabilities investigated. only couple days training data achieve reasonable results. As focus on real-world application LSTMs, from two different distribution plants benchmarking. Finally, it significantly operation.

When solving constrained multiobjective optimization problems, an important issue is how to balance convergence, diversity, and feasibility simultaneously. To address this issue, paper proposes a parameter-free constraint handling technique, two-archive evolutionary algorithm, for optimization. It maintains two collaborative archives simultaneously: one, denoted as the convergence-oriented archive (CA), driving force push population toward Pareto front; other diversity-oriented (DA), mainly tends maintain diversity. In particular, complement behavior of CA provide much diversified information possible, DA aims at exploring areas under-exploited by including infeasible regions. leverage complementary effects both archives, we develop restricted mating selection mechanism that adaptively chooses appropriate parents from them according their evolution status. Comprehensive experiments on series benchmark problems real-world case study fully demonstrate competitiveness our proposed in comparison five state-of-the-art optimizers.

Constrained multiobjective optimization problems (CMOPs) are challenging because of the difficulty in handling both multiple objectives and constraints. While some evolutionary algorithms have demonstrated high performance on most CMOPs, they exhibit bad convergence or diversity CMOPs with small feasible regions. To remedy this issue, article proposes a coevolutionary framework for constrained optimization, which solves complex CMOP assisted by simple helper problem. The proposed evolves one population to solve original another problem derived from one. two populations evolved same optimizer separately, assistance solving is achieved sharing useful information between populations. In experiments, compared several state-of-the-art tailored CMOPs. High competitiveness applying it 47 benchmark vehicle routing time windows.

Handling constrained multiobjective optimization problems (CMOPs) is extremely challenging, since multiple conflicting objectives subject to various constraints require be simultaneously optimized. To deal with CMOPs, numerous evolutionary algorithms (CMOEAs) have been proposed in recent years, and they achieved promising performance. However, there has few literature on the systematic review of related studies currently. This article provides a comprehensive survey for optimization. We first large number CMOEAs through categorization analyze their advantages drawbacks each category. Then, we summarize benchmark test investigate performance different constraint handling techniques (CHTs) algorithms, followed by some emerging representative applications CMOEAs. Finally, discuss new challenges point out directions future research field

Model Predictive Control (MPC) has recently gained increasing interest in the adaptive management of water resources systems due to its capability incorporating disturbance forecasts into real-time optimal control problems. Yet, related literature is scattered with heterogeneous applications, case-specific problem settings, and results that are hardly generalized transferable across systems. Here, we systematically review 149 peer-reviewed journal articles published over last 25 years on MPC applied reservoirs, open channels, urban networks identify common trends challenges research practice. The three consider inter-connected, multi-purpose multi-scale dynamical affected by multiple hydro-climatic uncertainties evolving socioeconomic factors. Our first identifies four main currently limiting most applications domain: (i) lack systematic benchmarking respect other methods; (ii) assessment impact model-based control; (iii) limited analysis diverse forecast types, resolutions, prediction horizons; (iv) under-consideration multi-objective nature We then argue future should focus addressing these as key priorities for developments.
