The gravitational search algorithm (GSA) is a population-based meta-heuristic optimization algorithm which finds the optimal solution by the law of gravity and attraction between objects. However, as the number of iterations increases, the increase of the quality of the agents makes GSA fall into the local optimal solution more easily, which greatly reduces the exploration capability of the algorithm. Although the chaotic gravitational search algorithm (CGSA) uses chaotic maps for improving diversity to solve this problem, it still has problems with the balance of exploration and exploitation. This paper proposes the balance adjustment based chaotic gravitational search algorithm (BA-CGSA), which introduces the sine randomness function and the balance mechanism to solve the above problem. 30 benchmark functions of IEEE CEC 2014 are adopted to evaluate the performance of the proposed algorithm in terms of exploration and exploitation. Meanwhile, a real engineering design problem is used to illustrate the ability of the algorithm to solve practical application problems. The experimental results demonstrate its good performance in continuous optimization problems. (C) 2019 Elsevier B.V. All rights reserved.

Recent social conditions have caused to rise of raw material prices in the manufacturing industry. In addition, efforts to realize a decarbonized society are gaining momentum worldwide. Therefore, the manufacturing industry is required to reduce manufacturing costs and energy consumption by improving production efficiency. The objective of this study is to equalize machine utilization rates to reduce product retention on the production line which causes lower production efficiency. To deal with this, this study aims to develop a production scheduling system. For this purpose, we propose and implement the system that optimizes production schedules by considering the start time of job processing and the processing order of jobs using the production line simulation. Experiments have shown that the proposed system can produce production schedules with shorter product retention time than those used in real factories.

With the increasing demand for electricity and the awareness of environmental protection, requirements for economic efficiency and controlling environmental impact of the power system are increasing. However, traditional power system scheduling usually focuses on ensuring the stability of the power supply, which neglects the optimization of cost and emissions. Therefore, combined economic and emission dispatch (CEED) problem is proposed to overcome this challenge. Due to nonlinear and nonconvex objective functions and narrow feasible regions, the optimization of multi-objective CEED problem encounters many difficulties. A dueling double deep Q network-assisted cooperative dual-population coevolutionary algorithm (D3QN-CDCA) is developed to solve multi-objective CEED problems. The proposed algorithm utilizes D3QN to select operators dynamically and adaptively for two populations of coevolutionary algorithm, thus enhancing its adaptability to different practical constrained multi-objective problems and satisfying search needs of different iteration stages. The introduction of D3QN is to overcome the inherent overestimation of DQN and improve the learning efficiency of the network. To comprehensively evaluate its performance, we tested D3QN-CDCA on benchmark function sets and applied it to CEED problems in comparison with other competitive algorithms. Results demonstrate that D3QN-CDCA outperforms existing methods with an average IGD+ ranking of 1.4286 and an average HV ranking of 1.321 in benchmark function sets. Meanwhile, the proposed algorithm achieves an average improvement of 23.86 % in 6unit, 23.12 % in 11-unit and 13.51 % in 14-unit CEED problems. The improvement in solution quality demonstrates the effectiveness of D3QN-CDCA in solving high-dimensional multi-objective optimization problems, particularly in CEED, highlighting its potential for real-world energy management applications.

This paper explores the set-membership estimation (SME) of T-S fuzzy complex networks (TSFCNs) under unknown but bounded process and measurement noises. To facilitate digital transmission, a dynamic coding-decoding mechanism is integrated into each communication channel between nodes. It employs a dynamic auxiliary variable to adjust the coding interval. Meanwhile, under a directed communication topology, a fuzzy estimator is designed for each node. This estimator utilizes relative measurement outputs from the node itself and its neighbors to determine an ellipsoidal set that encapsulates the system state at each instant. Furthermore, two optimization problems are formulated to establish sufficient conditions for the desired estimators, ensuring that specified performance requirements are satisfied. Finally, numerical simulations are provided to validate the effectiveness of the SME method for TSFCNs.

In practical printed circuit boards (PCB) drilling production systems, multiple spindle processing capabilities and uncertainties are commonplace. This paper addresses predictive-reactive scheduling, considering parallel batch processor lot-sizing and scheduling with sequence-dependent setup times in a dynamic environment. We propose a predictive scheduling algorithm named S-AGAIG to balance machine spindle utilization and order tardiness in steps. Multiple splitting solutions are first formed by using a split heuristic algorithm to size the sub -lots of orders. Then the adaptive genetic algorithm with iterated greedy search is applied to select the solutions and scheduling. Furthermore, we present a schedule repair strategy based on sub -lot co-processing considering the impact of critical sub -lots, and construct a scheduling stability metric for rescheduling. In 36 sets of case experiments encompassing diverse load and machine type configurations, S-AGAIG showcases a 21.27% enhancement in average tardiness performance when compared to its closest rival. Across 28 cases involving varying disturbances, the framework demonstrates exceptional robustness.

Energy consumption is a critical concern within the electric vehicle (EV) industry. Despite its substantial impact, drivetrain losses have been inadequately addressed in some studies. This paper introduces drivetrain losses as a nonlinear function of velocity, incorporating them into the comprehensive energy consumption model. Considering the influence of traffic congestion on vehicle speed, our proposed model integrates drivetrain losses, aerodynamic losses, tire losses, kinetic energy losses, and potential energy losses. The objective is to optimize routing with the aim of minimizing energy consumption. To tackle this problem, we present a dedicated adaptive large neighborhood search algorithm. Our numerical experiments reveal key findings: (1) Drivetrain losses represent a higher percentage of total energy consumption compared to aerodynamic and tire losses;(2) Drivetrain losses influenced by traffic congestion constitute a significant share, ranging between 63.82% and 72.08% of total energy consumption;(3) Energy consumption experiences notable increases under the impact of traffic congestion.

Efficient and Robust Sparse Linear Discriminant Analysis for Data Classification

Sparse linear discriminant analysis (LDA) is a popular machine learning method that improves the accuracy of data classification by introducing sparsity. However, its performance often degrades seriously when encountering noise. To address this issue, this paper proposes a new method called efficient and robust sparse linear discriminant analysis (ERSLDA). The core idea is to characterize the local pixel corruptions by integrating L-p-norm (0< p< 1), and to describe the global structured sparsity by enforcing L-2,L-p-norm (0< p< 1), thereby improving the ability of feature selection. Compared with existing L-1-norm and L-2,L-1-norm, the involved L-p-norm and L-2,L-p-norm can bring higher robustness and better accuracy. Moreover, an additional matrix with Frobenius norm is embedded to represent Gaussian noise, which further enhances the robustness in different scenarios. In algorithms, an iterative optimization scheme is developed based on the alternating direction method of multipliers (ADMM) to solve the proposed ERSLDA, and the resulting subproblems can be calculated efficiently. Extensive numerical comparisons are performed with nine state-of-the-art LDA-based methods on seven benchmark image datasets. The experimental results validate that the proposed method is efficient for data classification and robust to noise.

Multidisciplinary design optimization approaches have been successfully applied to many flight vehicle design problems in academia and are now becoming more common in industry. Typically, the vehicle design is optimized given a constrained trajectory, or the trajectory is optimized given a fixed vehicle design;however, simultaneous vehicle/trajectory optimization is very challenging. Certain applications, even for conceptual design, demand higher fidelity in the vehicle model and/or trajectory solver, which is possible given sufficient computational resources. This paper describes missile conceptual design optimization methods and software tools under development for more than a decade at the Johns Hopkins University Applied Physics Laboratory. These methods are applied to the problem of simultaneous vehicle and trajectory design optimization to demonstrate how that coupling drives performance for a hypothetical boost-glide hypersonic vehicle.

The structural deformation measuring of coal mine roadways is an effective method to prevent dynamic disasters and avoid loss of civilian life and property. Previous studies on structural deformation early warning, however, failed on multisource uncertain data integration, dynamic adaptability, and limiting the updating ability of models. To address the above issues, this article proposes a structural deformation warning method for coal mine roadway surrounding rock based on evidential reasoning. The evidential reasoning theory is used to construct the models for predicting the deformation value and evaluating the stability level of the surrounding rock through multiple-source data fusion. Moreover, the online optimization mechanism is proposed to improve the performance of the evidence reasoning (ER)-based models. The proposed deformation warning method is evaluated on real coal mine roadway surrounding rock data. Experiment results demonstrate that the proposed method model performs well in deformation prediction with the advantage of dynamic updating and the roadway surrounding stability evaluation.
