According to authorities and statistical figures, Iran is seriously facing insufficient housing crisis. Studies show that through an increase of 1.5 million units in annual housing construction capacity, this crisis will be overcome in 5 years. Although successful execution of such a big project is not unprecedented in the world, housing experts believe fulfillment of this plan through traditional method of construction in the country is impossible. The country's capacity of industrialized construction which is known as the remedy, is only limited to 2-3% of total construction. Thus development of this approach through financial, legal, ... supports of investment in prefabrication... 

Statistics is an essential part of decision making and management in all organizations if the needed information is correct and updated. Due to lack of suitable information systems, it needs rework and spend extra time to gather information. Information Technology is used to summarize organizational information. It supports management of organization to make decision for strategic planning, tactical planning and operational programming by creation, storage, retrieve and distribute correct information to managers. For implementing these systems, there are many solutions. Selecting each one depends on conditions and potentials. Implementing integrated systems is expensive task therefore large... 

To deliver gas in time to different consumers like as industrial, commercial and domestic users is one of the most important parts in gas industry. So it is very important to utilize these projects in the specified time. There are huge harms for client, contractors and consumers when there is a delay in project utilization. To identify effective parameters on delays to remove them in future is an essential factor. In this research, all delay causes for TPGC (Tehran Province Gas Company) projects are analyzed and some solutions to remove these delays are presented. 10 hypotheses in relation of gas delivery have been assumed as delay causes. Then some questions have been discussed in relation... 

This research represents findings about obstacles in using value engineering in construction projects of khorasan razavi province via collection of information and views of experts of value engineering.The research shows that the value engineering in the majority of the projects is not practiced and majority of the projects are not benefited from this technique. Many experts believe that lack of required culture and motivation to save up and lack of organisational position for this technique are the main factors for non-progressive use of assessment engineering.The absence of proper understanding of the objectives and place of the value engineering is also an effective factor of on its...

In recent decades many countries have attempted to measure and formulate customer satisfaction index (CSI), as an important factor in micro and macro-economic level. In developed country CSI has the same value of GNP. Customer Satisfaction Index model actually represents the relationship between primary factors of satisfaction and satisfaction results in the macro level for a country and includes all business aspects. In many countries, industrial companies have a wide range of products and providing Customer Satisfaction Index model for this aspect which can be a base of presenting national customer satisfaction index model. Accordingly, the main goal of this study is providing an Iranian...

Iran with the second largest gas reserves in the world makes the importance of Kish Island more vital. Kish gas field, with a capacity of 67 trillion cubic meters gas, is one of the main hubs of Iran gas production. One of the uses of natural gas is to produce petrochemical goods such as Methanol. In this thesis the focus is on economical evaluation of producing Methanol for amount of 5,000 tons per day from Kish gas field. As a result, the required feed has been estimated about 150 million cubic feet per day and the net capital investment calculated to be 941 million US dollars. The initial estimate of Direct Permanent Investment (DPI) was calculated to be $590.8 million. Having considered...
