This article considers the problem of risk-optimal allocation security measures when actuators an uncertain control system are under attack. We consider adversary injecting false data into actuator channels. The attack impact is characterized by maximum performance loss caused a stealthy with bounded energy. Since random variable, due to uncertainty, we use Conditional Value-at-Risk (CVaR) char...

In this paper, a new methodology based on system modelling and optimization is developed to determine forest fire risk, and subsequent resource allocation, over a regional area. A forest fuel moisture model and a propagation model are developed, in order to determine the dynamic risk assessment. The objective of resource allocation is twofold. In the preventive phase means and crews are re-allo...

In addressing questions surrounding the comparison of different popula-tions' health, the first issue to be raised is whether devoting scarce analytical resources on attempting to answer them is worthwhile. A second issue is whether these questions are capable of being answered satisfactorily. Only after that does it seem important to try to address more direct questions of how best to do this....

A ‘robust decision maker’ suspects that his model is misspecified and makes decisions that work well over a restricted range of specification errors around a base or ‘reference’ model. In the context of a discrete time linear-quadratic permanent income model, Hansen, Sargent and Tallarini (1997) (HST) used a single parameter – taken from a version of Jacobson and Whittle’s ‘risk-sensitivity’ co...

BACKGROUND Meta-analysis of registries (comparative effectiveness research) shows that primary angioplasty and fibrinolysis have equivalent real-world survival. Yet, randomized, controlled trials consistently find primary angioplasty superior. Can unequal allocation of higher-risk patients in registries have masked primary angioplasty benefit? METHODS AND RESULTS First, we constructed a model...

Power networks are among the most important infrastructures that without them, industrial, economic and social procedures will halt. Therefore, they should be planned for the most difficult conditions to provide services with minimum disruption. Power substations are of great importance to a power network, because any disruption in their components can produce extensive problems through the net...
