Undoubtedly, all governments which was created in Iran for keeping their stability against the strange forces and opponents and in order to cope with inner conflicts and some problems that made them worry about military troops and their needs for recognizing military troops. When the king Abbas felt betrayal from Ghezlbash army, created a new military troops namely Gholaman. He prepared a Shahsavan army which protects Safavi Government against Ghezelbash’s commander's rebellion, as well as empowerd them against the strangers and that was more effective than Ghezelbash’s guerrilla forces. The main aim of current research is investigation of Functional and applicable military and Entezami troops amends from Iran’s government in Safavieh era. Moreover, to what extent Safavie government felt the power of military troops for keeping its’ kingdom and power? Eventually, results elucidate that, the composition of Safavie government from the starting point was based on tribal form and was out of the latest version of equipment, education and cohesion. The army men preferred the tribal benefits to national one. The military troop’s duty was in both fields of Nezami and Entezami. Kings needed the teaching military science, updating the equipment. Number of kings for example King Abbas achieved some success and the other ones was not able to attain this goal due to their monetary problems and tribal functions and the other parameters.

With the increase in population of cities and progress of technology, people demand toward a comfortable life has also increased. Traffic jams in big cities and shortage of parking lots have made necessary the need for use of underground spaces more than ever. The use of underground metro trains as a fast and safe vehicle could be appropriate alternative for passengers. However, movement of trains with appropriate speed in between stations produces vibrations that may sometimes be disturbing for people living in the region. These vibrations which are one of the most serious concerns related to region close to transportation systems could cause vibration of structures and hazardous noises inside buildings. In addition to hazard to human, these vibrations could affect old buildings and equipments. They could cause fatigue in the materials of ground and structure, create differential settlement, crack in walls, resonance and other difficulties. Therefore, in designing new rail road, evaluation of vibrations due to movement of trains is one of the important parameter in selecting the route and the type of rail system. In this research the vibrations in the ground surface due to passage of metro trains in city of Ahvaz metro under construction were evaluated.
By performing dynamic analysis on each station along the metro line and also using empirical method, the vibrations due to passage of train on the surface of ground were predicted and the regions that have high vibration potential are identified. Also the effects of different parameters on these vibrations were evaluated. The results show that in general the levels of vibrations in the northeast part of the route are higher than the southwest part. One of the most important factors responsible for this observation is the shallow depth of the rock and also soil profile in the northeast part of the route. Also the results show that utilization of new methods for damping vibrations cause a considerable decrease in the level of vibrations.

Nowadays، the performance of critical assets in the industrial and urban sites depends on network-based systems. With respect to this fact that an infrastructure (as a complex system) consists of several assets، it is clear that assets play a vital role in daily performance of the urban systems. This study developed a novel model to analyze the interdependency of critical assets in an industrial system. The most famous conventional method regarding the interdependency of the assets (Leontief) were considered، which suffer from some weaknesses. However، the new model was extended with new abilities. In the proposed model، the assets were classified into two states: resource and demander. The objective of this model is to estimate the interaction of assets using an innovative Operation Research (OR) framework in order to simulate the mechanism of dependency of assets. To obtain the criticality of assets، a new term entitled by “centrality” was introduced to select and to rank the assets. A notional example was provided to illustrate the application of the proposed model.

In recent years, intensive research and development has been done in the area of construction Projects Risk Management (PRM). It is widely recognized as one of the most critical procedures and capability areas in the field of project management (Klemetti, 2006). Failures in risk management in construction are often seen as spectacular structural collapses or serious accidents, however, the project risk management covers a wider field than that of human and structural safety.
A significant number of construction failures and collapses occur during the construction phase and in most of the cases these failures involve the temporary structures and equipment which are used during the construction process (Mehdizadeh et al., 2013). However, failure of projects is not limited to these kinds of accidents and collapses. Cost overruns are not uncommon, especially in complex projects. Also the problem of delay is a global phenomenon and a project is considered 'successful' if it is completed on time, within budget and to the specified quality standards. After examining more than 1,000 site-based projects from over 100 different manufacturing sites around the world by IPA (© Independent Project Analysis), the study found that, on average, only 37 percent of the projects at a site meet the success criteria, including schedule, safety, operability and final cost of the project (IPA, 2011).
