A pavement management system (PMS) is a set of tools that aid the decision makers in finding optimum strategies for maintaining pavements in a serviceable condition over a given period of time. A frame work for pavement management system for Iran was proposed by Tabatabaee et al. with the support of Transportation Research Institute of Ministry of Road and Transportation. In the proposed frame work, two horizons of development, short and long term, have been envisaged for more rapid and efficient utilization of the system within the technical and administrative divisions of the Ministry. This thesis describes the software package developed based on the proposed frame work for the... 

Iran is a country with bright cultural and historical background, and rich natural resources. It is also one of the important oil and gas exporters with a special geographical situation. The world energy needs are increasing rapidly and that requires higher oil production. On the other hand, oil is Iran’s most important source of revenue and the country is highly dependent on oil export. Islamic republic of Iran’s (I.R.I) 1404 program is visioning the country to be the first producer of material in the region, the second producer of oil in OPEC, and the third producer of gas in the world. Although critical conditions can slow down the process to achieve the vision, implementing this vision... 

As aircraft fleets get older, the challenge of Flight Safety gets greater. This Thesis focus on management strategies and principles to keep long-life fleet safe and effective into old age. But the safety and efficacy are not the only ones who are considered at long-life fleet. Here the question arises why the aircraft prior to exposure to the effects of rising life expectancy, are not replaced by other aircraft.The reason is the high cost of the replacement. Aircraft are expensive to design and manufacture. In commercial aviation, extreme competition and miniscule profit force pressures to delay replacement of older aircraft with expensive new types. But in Military aircraft reason for... 

In contrast to traditional Networks where a designer can specify an action plan for each agent, in a network with strategic agents, every agent acts selfishly and chooses his strategy privately so as to maximize his own objective. In this dissertation, we study problems arising in the design of static and dynamic networks with strategic agents. We consider two classes of design problems. In the first class, the designer utilizes her control over decisions and resources in the system to incentivize the agents via monetary incentive mechanisms to reveal their private information that is crucial for the efficient operation of the system. In this class of problems, we address two main challenges...
