With more and renewable energy connected to the power system, system gradually presents characteristics of low inertia risk frequency instability becomes prominent. Therefore, nadir has become one limiting factors carrying capacity. In this paper, firstly, based on swing equation, dynamic response after loss was analysed. Secondly, quantitative analysis time with resources carried out, higher p...

The present study introduced a novel hierarchical hub set covering problem with capacity constraints. This study showed the significance of fixed charge costs for locating facilities, assigning hub links and designing a productivity network. The proposed model employs mixed integer programming to locate facilities and establish links between nodes according to the travel time between an origin-...

<p style='text-indent:20px;'>In recent years, numerous studies have been conducted regarding inventory control of deteriorating items. However, due to the complexity solution methods, various real assumptions such as discrete variables and capacity constraints were neglected. In this study, we presented a multi-item model for items with limited carrier capacity. The proposed research cons...

The consequences of imposing a sign constraint on the standard Hopfield architecture associative memory model, trained using perceptron like learning rules, is examined. Such learning rules have been shown to have capacity of at most half of their unconstrained versions. This paper reports experimental investigations into the consequences of constraining the sign of the network weights in terms...

The problem considered in this paper is whether the capacity of a discrete time Gaussian channel is increased by feedback or not. It is well known that the capacity of a white Gaussian channel under the average power constraint is not changed by feedback. In the previous paper [7] we gave some sufficient conditions under which the capacity of a non-white Gaussian channel is increased by feedbac...

Information capacity is determined for a Gaussian communication channel when the constraint is given in terms of a covariance which is different from that of the channel noise. AMS (M)S) subject classifications (1970): Primary, 94A15, 60G35

Given a set of n items with weights wi, i = 1, . . . , n, the bin packing (BP) problem consists of finding the minimum number of bins of capacity C necessary to pack the items, without violating the capacity constraint. This formulation also entails another problem (DBP), in which we seek to minimize the capacity of a fixed number m of identical bins, so that all items fit in the m bins without...

This paper explores the relationship between constrained capacity and supply chain performance. Six capacity constraint levels are studied under different inventory policies and information sharing strategies. The results suggest that an increment of production capacity, used in industry as local approach to manage increasing incoming orders, does not necessarily imply an improvement in custome...
