The purpose of response phase after a disaster is to reduce mortality by accessing affected areas in order to transport relief items and search and rescue activities as soon as possible. Debris caused by the disaster blocks the roads and prevents emergency aid teams to access the disaster affected regions. Deciding which roads to clean in order to transport relief items is crucial to diminish the negative effect of a disaster on human health. In this paper we developed a mixed integer mathematical model for the debris clearance problem considering multi-depot and multi-vehicle. The aim of our model is to minimize the maximum walk of the vehicles. For decreasing the computational time, we developed a two-phase heuristic based on simulated annealing. Validity and applicability of the proposed model and solution algorithm is tested and analysed in a region of Tehran, Iran. The results of this experiment underlie the importance of multi-depot and considering a comprehensive plan for the debris removal problem in the response phase.

Dams as one of the most important energy infrastructure have a significant role in water supply of the region, province or country. Also in terms of energy, they are hydro electrical-water power stations that produce electrical energy from the potential energy in the water behind the dam. Therefore, from the perspective of emergency management, identifying any degradation (cracks, break, etc.) in the body of the dam is very important. Because ultimately, these damages can lead to a break of the dam and the break dam caused a very big emergency for the region. This paper attempts to design a warning image system using synthetic aperture radar (SAR), in order to detect any degradation in the body of the dam and thus guarantee the performance continuation of the dam. System designed unlike warning optical system capable to imaging in any weather (fog, dust, etc.) and compares the taken image and saved image from healthy dam, to extract the degradation area in the desired dam.

This paper proposes a scheduling based vehicle routing methodology for disaster damages and relief assessment teams. Relief assessment teams are dispatched in disaster area in order to assess the relief demand. In this process, time is very sensitive so these teams are supposed to collect the information of relief demand as soon as possible. In this paper a maximum completion time is proposed as objective function. This objective function is used instead of usual sum of arrival time to show its better performance. This problem is solved using particle swarm optimization which is a Meta heuristic optimization algorithm. The result of proposed model is compared with sum of arrival time. These results show that the proposed model leads to a less completion time of assessment process rather than sum of arrival time. This model is solved in two randomly generated networks for evaluating its performance. The results show 10 percent improvement in small network and 16.9 percent in a big (real size) network.

Natural hazard risk assessment helps decision makers for planning and prioritizing disaster management strategies. This paper focuses on the prediction of different scenarios and assessing the risk of soil liquefaction. The vulnerability of the elements due to soil liquefaction was determined. The Gorgan state (1600 km2), Golestan Province, Iran was considered as a case study for assessing the vulnerability due to this phenomenon. Soil deposits map, ground water depth, and the earthquake acceleration map (based on the occurred historical earthquake points) have been prepared for this study. An empirical liquefaction model as a function of the three studied variables was used to model the liquefaction in four hazard classes using the ArcGIS software. Possible scenarios were determined considering the potential of superposing the peak rate of the ground acceleration and water depth. The area of liquefied zones was estimated using the geographical information systems (GIS). In this study , the collection of data and digital maps using ArcGIS software base as well as three-parameter model SWM, soil liquefaction hazard zonation map of the area south of Gorgan in Golestan province in Slvlhay30Ï30 were prepared . According to the results of without risk to very high risk potential that the area most studied in class is without risk. Aq Qala city limits because of the proximity to the center -discharge is too high earthquake hazard class, and because Gorganrood the scope of this town passes increases the probability of liquefaction.

One of the most important issues that the country is faced with, is resistive economic, which seeks retrofit and restoration of old and inefficient infrastructures and institutions of the country. One of the ways to achieve this plan, is to ignore the economy which is based on incomes of selling raw materials and natural resources. And this will be possible only through developing knowledge and technology. Thus, we need public attitude to knowledge based economy and implementation of knowledge management in our organizations.
In this study, the effect of the knowledge management processes on resistive economy has been studied in Ansar Bank. Data were collected through a questionnaire with 34 questions which is asked among 84 experts and staff of Ansar bank that were familiar with knowledge management and resistive economy. The model is presented by using structural equation modeling (PLS) and has been tested and interpreted by Smart PLS software. Test results show that knowledge management has a significant and positive impact on the resistive economy, and the Organization by investment in knowledge management can indirectly help the country achieves resistive economic.

Tabriz fault is one of the active and dangerous fault in the North West of Iran. The fault crosses the north of the city and put crossing towns at risk. The majority of marginal inhabitants of the city are settled there. Their buildings do not resist the slightest shake. Analysis of seismic data using polynomial regression for predicting future earthquake's magnitude and risks can be helpful to reduce disaster results. First of all input data are extracted and normalized. At the second step, model is obtained. In the third step, the magnitude of earthquake for the test data is predicated. In the fourth step, the performance of predicting earthquake magnitude is evaluated. At last, to estimate the magnitude of earthquakes using other attributes a formula is obtained that can be used to estimate the coefficients of each of the independent variables.

In the world today, because of many social and military unrests and different kinds of critical points and military bases, the issue of potential and actual threats are very important in the strategic plan of the most of countries. Attacking critical infrastructures and industries is one of the very operative aggressive tools for debilitating countries as military targets. Therefore critical infrastructure security and vulnerability reduction are described in article one and two of the legislative plan of passive defense organization in our country. So, recognizing the general vulnerability indexes of industrial complexes is the main purpose of this paper. In order to reach this purpose content analysis method and numerical taxonomy system are used in this research. The general vulnerability concept is classified in three dimensions of special planning, structural aspect of industrial complexes and the ability of detection of them from the adversary point of view. This article will be ended in identification of vulnerability indexes through description of these dimension and effective components on vulnerability.

Nowadays existing urban network problems and resolving them is nation wide problems so that one of the most important and most expensive units in urban services companies is events system. In urban networks infrastructure during events, access to spatial data and suitable descriptive and relevant to the current situation at the event site is essential. National Iranian Gas Company by having more than 17,000 km of gas pipelines, it has one of the largest collection spatial and attribute data. During incidence of events in many cases need to cut off gas in part that damaged, so identify the nearest valves to event site is of the most important factors. In this study, it was shown that Volunteered data can be many help to identify the nearest valves to event site and using Volunteered Geographic Information environments and native people information could be a faster and less costly way to update the maps and expedite the process of servicing in Gas urban network, while occurrence of problems such as Gas pipes leakage, pipes rupture and in general while events occurrence. People by observing such events, their information shared on this system and of course the relevant authorities after becoming aware, can do necessary action. After modeling and design of the proposed system, its implementation was done in the frameworks and softwares cited in article. Finally, according to the questioning results from people, about 83 percent of participants in the inquiry were satisfied with the designed system. Also, questioning results from seven water organization experts, five of them were satisfied with designing such a system.
