In this study, a new parameter control scheme is proposed for the differential evolution algorithm. The developed linear bias reduction scheme controls the Lehmer mean parameter value depending on the optimization stage, allowing the algorithm to improve the exploration properties at the beginning of the search and speed up the exploitation at the end of the search. As a basic algorithm, the L-SHADE approach is considered, as well as its modifications, namely the jSO and DISH algorithms. The experiments are performed on the CEC 2017 and 2020 bound-constrained benchmark problems, and the performed statistical comparison of the results demonstrates that the linear bias reduction allows significant improvement of the differential evolution performance for various types of optimization problems.

Modularity is widely used in system analysis and design such as complex engineering products and their organization, and modularity is also the key to solving optimization problems efficiently via problem decomposition. We first discover modularity in a system and then leverage this knowledge to improve the performance of the system. In this chapter, we tackle both problems with the alliance of organizational theory and evolutionary computation. First, we cluster the dependency structure matrix (DSM) of a system using a simple genetic algorithm (GA) and an information theoretic-based metric. Then we design a better GA through the decomposition of the optimization problem using the proposed DSM clustering method.

We consider two storage/production systems in which items are produced continuously over time with fixed rate. In the first system items have infinite lifetime, while in the second system the lifetime of the items are finite and fixed. The inventory level distributions and other important functionals associated with these storage systems are derived. This derivation is accomplished by an analogy existing between the storage systems and certain queueing systems and a finite dam model. Optimization problems connected with these systems are also considered.

A typical modern optimization technique is usually either heuristic or metaheuristic. This technique has managed to solve some optimization problems in the research area of science, engineering, and industry. However, implementation strategy of metaheuristic for accuracy improvement on convolution neural networks (CNN), a famous deep learning method, is still rarely investigated. Deep learning relates to a type of machine learning technique, where its aim is to move closer to the goal of artificial intelligence of creating a machine that could successfully perform any intellectual tasks that can be carried out by a human. In this paper, we propose the implementation strategy of three popular metaheuristic approaches, that is, simulated annealing, differential evolution, and harmony search, to optimize CNN. The performances of these metaheuristic methods in optimizing CNN on classifying MNIST and CIFAR dataset were evaluated and compared. Furthermore, the proposed methods are also compared with the original CNN. Although the proposed methods show an increase in the computation time, their accuracy has also been improved (up to 7.14 percent).

AbstractChange in the semi-natural vegetation of the hills and uplands of the UK is a relatively slow process. Whilst exogenous influences, such as climate and air quality, can influence the rate of change, the principal means whereby more rapid change can occur is through the actions of man in managing such resources to meet a range of objectives. Burning and grazing by large herbivores are the two most important management practices adopted and their interaction is central to the maintenance of vegetation in its current state and to its direction of change. This paper reviews how vegetation change associated with grazing occurs, how it can be measured, what the critical levels of grazing are for the most abundant species and what the implications of grazing are for nutrient supply for animal production systems.


The article considers modern approaches to improvement of production processes at the enterprise, practical application of production development methods, issues of realization of production technologies in industry. A necessary condition for development of production is disclosed - increasing the efficiency of using technological potential through realization of the potential for strengthening its control systems. The article is devoted to studying the variability of application of adaptive methods for improvement of processes, technologies, and systems. Also, the effectiveness of development methods is determined by the example of their adaptation to the practice of the economic entity. Solutions to increase the competitiveness of enterprises cover the sphere of production, development of organizational systems of management, and "Kaizen" system. Analysis of practice and modern approaches to increase competitiveness is carried out in the context of implementation of solutions by domestic producers. In the course of the research it is determined that to solve tasks, it is necessary to develop the technological process of manufacturing product, as well as elements of the production system in part maintenance and operation of equipment. It is proved that the implementation of production development program will increase the utilization of production capacities, reduce the cost of production, change the indicator of time maintenance of production machines and equipment, and reduce used production area.

The paper reveals the current problems of production systems, their lack of readiness to function in the conditions of application and development of NBIC technologies. The methodological basis of the research consists of fundamental works and modern scientific and practical developments of national and foreign scientists on the problems of creation and functioning of production, technological and socio-economic systems in the conditions of development using NBIC technologies. The research was carried out using such general scientific and special methods as: historical-dialectical and abstract-logical; comparative-analytical and system analysis; synthesis of scientific approaches. The authors prove the need to create a new system paradigm. The new paradigm of production systems that realize the potential of NBIC technologies is based on a concept that finds its concrete expression, firstly, in the initial or original concepts, and secondly, in the system of basic principles, laws, or sufficiently plausible hypotheses. It is these elements that make up the conceptual core of the paradigm, and efforts should be directed to their search and justification when forming a new paradigm. The paper analyzes the main methods and tools for implementing a new approach to the design of production systems.
