Natural or man-made crises and disasters often bring large scale financial, environmental and human losses and can result in widespread damage to the information infrastructure. This affects the responding agencies’ ability to communicate, with restrictions on the sharing of information making it difficult for them to provide emergency services to the population. Emergency ad hoc communication ...

The OSIRIS project addresses the disaster management workflow in the phases of risk monitoring and crisis management. Risk monitoring allows the continuous observation of endangered areas combined with sensor deployment strategies. The crisis management focuses on particular events and the support by sensor networks. Four complementary live demonstrations will validate the OSIRIS approach. Thes...

This paper presents an architecture of a discrete-event and agent-based crisis response simulation model. In multi-agent systems as a computational organisation, agents are modelled and implemented separately from the environmental model. We follow this perspective and propose an architecture in which the crisis environment is modelled using discrete events and entities, and the crisis response...

We study the dynamics of correlation and variance in systems under the load of environmental factors. A universal effect in ensembles of similar systems under load of similar factors is described: in crisis, typically, even before obvious symptoms of crisis appear, correlation increases, and, at the same time, variance (and volatility) increases too. After the crisis achieves its bottom, it can...

In crisis, decisions must be made in human perceptual timeframes under pressure to respond to dynamic uncertain conditions. To be effective management must have access to real time environmental data in a form that can be immediately understood and acted upon. The emerging computing model of Dynamic Data-Driven Application Systems (DDDAS) fits well in crisis situations where rapid decision-maki...

This paper presents a crisis response simulation model architecture combining a discrete-event simulation (DES) environment for a crisis scenario with an agent-based model of the response organization. In multi-agent systems (MAS) as a computational organization, agents are modeled and implemented separately from the environmental model. We follow this perspective and submit an architecture in ...

Environmental protection has a key role in the context of crisis management. It is not just about development of the industry of environmental protection and implementation of new ways of management in innovative solutions in solving problems. Important area of improvement is also revision of environmental legislation aiming at simplification and reduction of costs of procedures for the busines...

The importance of aquaculture in the fishery sector is increasing. The growth of aquaculture complements the stagnant growth of extractive fisheries. Many countries are now entering this emerging economic activity. This positive feature has some serious drawbacks when the country has no local institutions to ensure the environmental sustainability of aquaculture. The Chilean salmon farming indu...

introduction small and medium-sized enterprises (smes) bring a broad range of benefits beyond growth of national income, providing important opportunities for employment, and are a key source of an outlet for entrepreneurial creativity and ideas. however, it is estimated that smes are responsible around 60 percent of carbon dioxide emissions and 70 percent of all pollution globally. therefore, ...

Our country, Iran, is in the category of waterless and survived countries because of lack of climate downfalls to its unsuitable local to temporal transmittance. Environmental concerns mainly after 1960s that have boon seriously proposed in universal politics, created a variety of assessments. In the late decades, environmental change such as: climate change, has caused chief challenges for the...
