Distributed scheduling with assembly machines has been an attractive research field in sustainable supply chains and multi-factory manufacturing systems. This paper investigates a distributed blocking flow shop scheduling problem with an assembly machine (DABFSP) with the total assembly completion time criterion, and proposes an effective discrete monarch butterfly optimization algorithm (EDMBO). First, a constructive heuristic combining the largest processing time rule and the earliest start assembly rule is provided to find a promising sequence. On this basis, an efficient initialization method is introduced to generate an initial population with high quality and diversity. Afterward, a global search procedure is presented, which integrates four kinds of improved operators and expands the solution space in a good direction. Then, according to different problem-specific characteristics, we present four targeted and flexible variable neighborhood search methods based on the critical job and critical factory to exploit the solution space. Finally, statistically significant numerical experiments are carried out with state-of-the-art optimization methods based on 1710 benchmark instances. The experimental results and detailed analysis demonstrate that the EDMBO is superior to preferred algorithms for addressing the DABFSP.

The aim of the study was to propose a new metaheuristic algorithm that combines parts of the well-known artificial bee colony (ABC) optimization with elements from the recent monarchbutterflyoptimization (MBO) algorithm. The idea is to improve the balance between the characteristics of exploration and exploitation in those algorithms in order to address the issues of trapping in local optimal solution, slow convergence, and low accuracy in numerical optimization problems. This article introduces a new hybrid approach by modifying the butterfly adjusting operator in MBO algorithm and uses that as a mutation operator to replace employee phase of the ABC algorithm. The new algorithm is called Hybrid ABC/MBO (HAM). The HAM algorithm is basically employed to boost the exploration versus exploitation balance of the original algorithms, by increasing the diversity of the ABC search process using a modified operator from MBO algorithm. The resultant design contains three components: The first and third component implements global search, while the second one performs local search. The proposed algorithm was evaluated using 13 benchmark functions and compared with the performance of nine metaheuristic methods from swarm intelligence and evolutionary computing: ABC, MBO, ACO, PSO, GA, DE, ES, PBIL, and STUDGA. The experimental results show that the HAM algorithm is clearly superior to the standard ABC and MBO algorithms, as well as to other well-known algorithms, in terms of achieving the best optimal value and convergence speed. The proposed HAM algorithm is a promising metaheuristic technique to be added to the repertory of optimization techniques at the disposal of researchers. The next step is to look into application fields for HAM.

This paper presents an improved non-iterative random vector functional link network hybrid model with better input-output representation, improved generalization for nonlinear dynamic system identification. The modified random vector functional link network model uses random weights between the input layer and hidden or enhancement layer neurons whose outputs are obtained by using two suitably weighted activation functions and additionally it provides a weighted direct link between the trigonometric functions based exponentially expanded the inputs and the output node. This novel architecture provides a direct link of inputs and its nonlinear expanded version in a higher dimensional space to the output node along with a randomized version of the hidden layer operating with an optimized added activation function to handle the chaotic nature of the non-linear dynamic systems. Also the weights and the parameters associated with the summed activation functions are optimized using an efficient modified sine cosine algorithm based monarchbutterflyalgorithm with levy distribution optimizationalgorithm with better exploitation and exploration capabilities in order to improve overall identification accuracy. To authenticate the efficiency of the proposed model, five benchmark dynamic plants are examined;the achieved outputs are compared with recognized methods like extreme learning machine, conventional random vector functional link network, and enhanced random vector functional link network with single activation function and least mean square. The method proposed here exhibits improved performance accuracy which is superior to the considered models. The proposed model is also compared with some iterative existing methods and found suitable by taking into consideration the merits of non-iterative approach,

This paper proposes a stochastic economic dispatch (SED) model for hydro-thermal-wind-photovoltaic power system (HTWPPS) considering mixed coal-blending combustion (MCBC) to improve the operational efficiencies of thermal power units (TPUs) with deep peak-regulating operation (DPRO). Firstly, the rations for different types of coal can be acquired by meeting the operational requirements of boilers. Three functions including the cost of coal consumption, polluting gas emission, and the life loss cost for TPUs could be obtained by fitting coal quality. Besides, they would be strictly piecewise linearized, respectively. Consequently, the objective function involving the above three kinds of costs as well as the cost of oil injection can be presented. Secondly, there is a two-stage framework for reducing the coupling of HTWPPS and improving the solving efficiency. In the first stage, the monarchbutterflyoptimization (MBO) algorithm is employed for obtaining the power outputs of hydro-power units (HPUs) taking the minimum water consumption as the objective. In the second stage, the load curve can be updated according to the results from the first stage. Besides, the Latin Hypercube Sampling method and the backward scene reduction technique are utilized to acquire a set of scenarios of wind power. In this way, the SED model considering MCBC can be achieved. The case studies have been carried out on a simplified provincial power system in China with the help of MATPOWER and CPLEX. The results show that the proposed model can effectively increase the economic and environmental benefits for TPUs.
