This thesis deals with the development of a hypothetical micronized powder factory and trying to test and engage in this hypothetical development of the following plant, it considers following factors:
1-Domestic & International market
2-Plant location
3-Plant design & development
a.machinery
b.technology & equipment
c.human resource
d.environment
e.packing
4-raw material
5-shipping & transport
To evaluate above factors the UNIDO methodology is used in this research work. The UNIDO methods are using a process by which feasibility studies of production facilities or plant are base on. After reviewing a variety of factors, ranging from financial... 

The methodology proposed by UNIDO , to investigate feasibility study of industrial project, is a useful tool in pre-investment decision making. In this work feasibility of investing on "Gas To Liquid" GTL Plant of Asalouye is investigated. Having gathered required information, including gas field potential, required technology and machineries, cost of investments , required manpower to run the UNIDO methodology is used to investigate the investment, the result of the work shows that the project is feasible and it would have internal rate of return of 24% ( by sale cost= 81 $ per barrel of GTL product)  

In competitive environment of quick market changes, developing an interoperable manufacturing system is a necessity. Process planning as a connection link between design and manufacturing, has never been able to integrate these up/down stream activities and in spite of employing computer systems, CAPP’s information has been managed in an isolated manner. To realize interoperability, the exchange of part and product data must be independent of their platforms. There are two basic approaches for this purpose: i) Utilizing interface and ii) Utilizing neutral formats. STEP (Standard for the Exchange of Product data) plays a significant role as a neutral data model to integrate design,... 

Nowadays, because of high volume and growth of data in industrial organizations and productive factories, registration and storing of data have forgotten manual and tradition styles for which using automation and mechanized machinery and systems has been a necessary task. In order to reach to this revolution, need to some tools, facilities and methods which can fulfill this requirement is felt strongly. Therefore, high volume of data is considered as an advantage because based on precise analysis it is possible to make logical management decisions with less risk. During last years, statistical and numerical methods and simulation were used to discover knowledge and information when one of... 

Lean Management is a set of procedures and processes that ensures firms’ survival in today’s world. Due to the global spread of lean management principles and rapid change of customer requirement in today’s markets, familiarity with these principles and deploying them seems crucial for firms that want to survive. In this research, Lean Management is implemented in a manufacturing company of heating and cooling devices. This process consists of two main processes. In the Business Renewal Process, the firm envisions its future and evaluates itself in nine keys of development based on lean principles. Diagnosis results indicates firm’s relative superiority in Customer Focus and Lean... 

The tourism industry, as the world's largest industry, plays a significant role in the economic status of developing and developed countries, and has been among the fastest growing sectors in other industries in recent decades.The important role of the tourism industry in economic development has begun since the 19th century, but it has quickly traveled its course as a global industrial one.This rapid growth will enable us to exploit the potential of this industry with the growth of technology and knowledge.Designing a platform with the ability to link up the supply and demand among existing individuals as potential sources of resources to reduce the cost and facilitate tourism with a cheap... 

Today, due to the development of information technology and fierce competition among manufacturers, the need to reduce the production costs and increase the variety are strongly felt. Each process in the cloud manufacturing is first considered as a service product development, and then, specializing each of these services, provides us a lower cost, along with a higher accuracy, and quality.The modern world is the world full of uncertainty. The uncertainty, which causes the manufacturers to develop products that consume a large quantity of, fixed costs. That is why utilizing such a perspective can reduce investment risk in a new product development. Combining the production services by... 

Assurance about projects and industrial plans success always had been one of the most important concerns of investors. Car manufacturing industry is not excluded. In this project the painting line in zagrosskhodro company using electro deposition method is reviewed , analyzed, and investment feasibility study of such method is investigated . All aspect of investment including financial and economic aspect is reviewed by UNIDO methodology.
The outcome is described here briefly.
1- Production volume in this plan in complete capacity is equal to 40000 bodies in a year.
2- The primary fixed investment capital is 132,187,912,140 Rls.
3- Sum of fixed expenses of production is ... 

Considering the significant role of process plans in computer-aided manufacturing, a lot of researches have been conducted to fulfill the gap between the different aspects of process planning systems. However, there is still a wide gap for process planning systems to completely fulfill the requirements. In this research an expert system for turning operation is proposed. The system is capable of suggesting appropriate machining parameters with the aid of an inference engine. The proposed system has an integrated data structure based on ISO 10303 (STEP) standard for both geometric design data and machining parameters. In this system, geometric design data is stored in a database with a data... 

A flexible manufacturing system (FMS) is a manufacturing system in which there is the capability of handling the variations in product's features which is the result of ever-changing customer demands. The flexibility attributes to utilize the resources in a more effective manner. On the other hand, the control of such systems would become more complicated. FMS needs CNC machines and robots and other resources for establishing the flexibility and enhancing the efficiency of the whole system. Also it needs to integrate the resources to reach flexibility. In order to reach this goal, an integrator framework is proposed in which the machining data of CNC machine is received through a STEP-NC... 

Telecommunication Company of Iran (TCI), as a government owned company that provides fixed, mobile and Internet services. It is in the process of privatization. In order to be survived in competitive environment, it is required to be an agile and dynamic organization. Also it should be seriously sensitive in profit margin. To be a dynamic company, the management of the company is expecting to introduce a new and modern service named Advanced Communication Services (ACS). This service consists of Video on Demand (VOD), live and archive television programs, tell-learning and e- shopping. For TCI, it's crucial to find a right and precise answer to the challenging question "Will ACS be a... 

In this thesis, we have studied systems called Ruthenates, which are common in possessing Ru element in their chemical compounds. Ruthenates are a group of transition metal oxides which have attracted so attention, especially in last years duo to their rich phase diagram which shows different orbital, charge and spin orderings.They cover a vast range of materials properties, from a Superconductor to Mott Hubbard insulator, from a paramagnetic metal to an antiferromanetic insulator. In these systems, substituting a covalent atom with structure base, leads to a vast variety changing, not only in electronic properties but also in magnetic and structural ones: Although Sr"RuO£ is a...
