摘要：
This paper is concerned with the dynamic characteristics of a class of Nicholson???s blowflies system with patch structure and multiple pairs of distinct timevarying delays. We aim to find the influence of the distinct time-varying delays in the same reproductive function on its asymptotic behavior. First, we derive the global existence, positiveness and uniform persistence of solutions for the addressed system. Then, by employing the theory of functional differential equations, the fluctuation lemma and the technique of differential inequalities, we build up some new delaydependent criteria for the global attractivity of the positive equilibrium point vector, which does not possess the same components. In addition, we exam the effectiveness and feasibility of the theoretical achievements by some numerical simulations.
摘要：
One of the most important challenges facing the optimal management of power resources for industrial cus-tomers is considering the latest available technologies for this purpose. In this regard, this article investigates the most important technologies and methods available in this field and tries to maintain the energy effi-ciency at a suitable level by presenting a knowledge-oriented approach. One of the most important technolo-gies used in this field is demand response, which provides an opportunity for consumers to provide an appropriate response to energy at various price rates by reducing or changing electricity consumption in peak load. In addition, the emergence of different renewable energy sources such as solar and wind in recent years has created a suitable opportunity for the participation of the majority of industrial and household con-sumers and as a result has increased social awareness in this field. The above items are investigated and dis-cussed one by one in this paper and the impact of each of them on meeting the needs of industrial customers is assessed. In the end, it is tried to present a model to show how to optimally use these resources in schedul-ing from the social, economic and technical point of view.& COPY; 2022 The Authors.
