Transportation project prioritization uses performance measures that are related to the transportation asset, its operations, and its environment. However, in the state of practice, evaluation does not consider directly the likelihood of natural or man-made threats, the infrastructure resilience, or the consequences of the infrastructure damage in the event that the threat occurs. Thus, during ...

Purpose In any information security risk assessment, vulnerabilities are usually identified by information-gathering techniques. However, vulnerability identification errors wrongly identified or unidentified vulnerabilities can occur as uncertain data are used. Furthermore, businesses’ security needs are not considered sufficiently. Hence, security functions may not protect business assets suf...

Managing risk has become a critical component of supply chain management. The implications of supply chain failures can be costly and lead to significant customer delivery delays. Though, different types of supply chain vulnerability management methodologies have been proposed for managing supply risk, most offer only point-based solutions that deal with a limited set of risks. This research ai...

Quantitative and qualitative monitoring and evaluation of risk management programs will play an important role in the development of Tehran metropolitan railway transport. Considering the tectonic studies, seismic zones, land degradation and faults in north and south of Tehran, the development of underground railway lines, the assessment of the vulnerability of subway stations and the escalatio...

Agriculture is a sector easily affected by meteorological conditions. Crop yield reduction, even regional conflicts, may occur during a drought. It is extremely important to improve the state of our knowledge on agricultural drought risk. This study has proposed a new method (vulnerability surfaces) for assessing vulnerability quantitatively and continuously by including the environmental varia...

sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

This study analyses the specific risks that organic farmers must manage. Due to the special features of management of their productive system, and due to the specific characteristics of their cultivations, they must face different risks than conventional farmers. Even if the Spanish farmers rely on the insurance system to manage their risks, today organic farmers do not have specific insurance ...

Risk assessments for natural hazards are becoming more widely used and accepted. Using an extended definition of risk, it becomes obvious that performant procedures for vulnerability assessments are vital for the success of the risk concept. However, there are large gaps in knowledge about vulnerability. To alleviate the situation, a conceptual extension of the scope of existing and new models ...

In the past 25 years, rising of the Caspian Sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. The main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. The goal of this study is to introduce a proper setback line for th...
