Modeling disruption propagation in a complex Supply Chain

2016 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM), 2016
A methodology to ascertain the impact of disruption downstream of the point of disruption is proposed. Two parameters were defined to quantify the extent of disruption in any node in the Supply Chain (SC), including the end customer. A complex SC network consisting of two sub-nets is discussed as an illustration of the methodology. Two experiments were

Situational awareness on disruption management: A system information propagation approach

Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics, 2011
Emergencies and disruption events bring new challenges to disruption management, a new analysis method is presented in this paper to search the solution, through the analysis of situational awareness, reasons of trend and changes of disruption events in different stages get the impact to whole supply chain become clear, this paper also provides the ...

Collaborative response to disruption propagation (CRDP) in cyber-physical systems and complex networks

Decision Support Systems, 2019
Abstract Disruptive events, such as natural disasters and manmade coordinated attacks, have inspired greater interests in the concept of disruption propagation and disruption response in cyber-physical systems (CPSs) and complex networks. Due to the high interconnectedness and complex interactions within and between CPSs, disruptions are not isolated

Quantifying disruptions propagation in a supply chain

2015 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM), 2015
Today's supply chain (SC) is highly complex and inter-connected so disruption at one company can propagate to other companies in an unexpected manner. However, most approaches in the area of risk management provide only static analysis of the SC risk but not the propagation of disruption through the SC network.

Disruption-Tolerant Routing with Scoped Propagation of Control Information

2007 IEEE International Conference on Communications, 2007
We consider the problem of routing messages through a network with episodic connectivity without a priori knowledge of node schedules or locations. We present Steward assisted routing (StAR), an efficient loop-free routing framework that can operate in networks that are well-connected as well as in networks that exhibit intermittent connectivity; the ...

Robust production control against propagation of disruptions

CIRP Annals, 2011
In hierarchical production control systems, planning decides on capacities and operations so as to meet demand, while scheduling should guarantee the execution of production plans even in face of uncertainties. The management practice advocates rolling horizon approaches despite the danger of plan nervousness.

Electromagnetic wave propagation in disrupted coal seams

SEG Technical Program Expanded Abstracts 1988, 1988
Abstract It is of economic importance to locate zones of geological disturbance in longwall coal panels prior to the start of mining operations. This can be done with electromagnetic (EM) longwall attenuation tomography in which the amplitude of a single frequency wave in the 300 kHz range is measured over a number of raypaths.

Disruption of alpha oscillation propagation in patients with schizophrenia

Clinical Neurophysiology
Propagation of electroencephalogram (EEG) oscillations, often referred to as traveling waves, reflects the role of brain oscillations in neural information transmission. This propagation can be distorted by brain disorders such as schizophrenia that features disconnection of neural information transmission (i.e., disconnection syndrome).
