Optimal Decision-Making Dealing with Enemy Sabotages Using the Maximum Flow Interdiction Problem in Multi-Period Dynamic Networks in Fuzzy Conditions [PDF]

open access: yesآینده‌پژوهی دفاعی, 2022
For a long time, one of the most important problems in wars has been the enemy's operations to destroy facilities and communication networks. The destruction of bridges and roads, air, missile, or artillery attacks, and the countless cyber-attacks in ...

On the maximum capacity augmentation algorithm for the maximum flow problem

open access: yesDiscrete Applied Mathematics, 1993
The subject of this paper is two variants of the classical path- augmentation algorithm for maximum capacitated flow problem. The main point of the paper is that both algorithms have polynomial bounds even when the capacities have real values. The first bound is \(O(m^ 2\log m)\) flow augmentations and \(O(m^ 3\log m)\) operations.

Coordinator MPC for maximizing plant throughput [PDF]

open access: yesModeling, Identification and Control, 2008
In many cases economic optimal operation is the same as maximum plant throughput, which is the same as maximum flow through the bottleneck(s). This insight may greatly simplify implementation. In this paper, we consider the case where the bottlenecks may

Inverse Generalized Maximum Flow Problems

open access: yesMathematics, 2019
A natural extension of maximum flow problems is called the generalized maximum flow problem taking into account the gain and loss factors for arcs. This paper investigates an inverse problem corresponding to this problem. It is to increase arc capacities

Solving Robust Variants of Integer Flow Problems with Uncertain Arc Capacities

open access: yesPromet (Zagreb), 2021
This paper deals with robust optimization and network flows. Several robust variants of integer flow problems are considered. They assume uncertainty of network arc capacities as well as of arc unit costs (where applicable).

Flows in Generalized Nets with Related Arcs

open access: yesМоделирование и анализ информационных систем, 2015
The problem of finding the maximum flow in nets of a special form is considered. In such nets the arcs are related in such a way that the total flow passing through the related arcs does not exceed the minimum throughput of these arcs.

Playing with the Maximum-Flow Problem

open access: yesEPiC Series in Computing, 2018
In the traditional maximum-flow problem, the goal is to transfer maximum flow in a network by directing, in each vertex in the network, incoming flow into outgoing edges. The problem has been extensively used in order to optimize the performance of networks in numerous application areas.

Heat transportation enrichment and elliptic cylindrical solution of time-dependent flow

open access: yesCase Studies in Thermal Engineering, 2021
The main focus of this article is to examine the effects of heat transfer for a compressible time-dependent laminar flow pass the two distinctly positioned elliptic cylinders. The Mac number is chosen below 0.3 to keep the flow laminar. The heat transfer

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.
