One of the applicable techniques which are used for modeling and solving optimization problems is response surface methodology (RSM). Response surface methodology is a collection of tools for fitting a surface to a set of data and determines optimal levels, this method used of a regression model for optimization problems Some real world problems include determining optimum values of input variables in order to obtain the desired levels of output variable (response surface variable). In this paper considering the Importance of four factors: Cooling Time, Pressure of injection, injection Speed and Heater temperature as the independent input variables for the variables of effective input factors and the response surface quantity and qualitative variable (Twin and Concurrently) in relation between input variables and response surface variables with the nonlinear regression model. Response variables would be crisp and fuzzy, for this Reason has been used of bi-level programming and fuzzy dual response surface methodology. Then the optimal value of each parameter is obtained by Meta-Heuristics algorithm (NSGA-II).

Nanotechnology policy making in different countries is performed using various programs. Each country according to its own characteristics and uses of various actors is endeavored critical to the development of this critical field of application. In Iran a special committee of nanotechnology as the key responsible to policy making in this area was formed in 2003 and two years later, Nanotechnology Development Plan has been formulated. This research using Network Analysis Approach is aimed to focus on Nanotechnology Strategic Plan in order to find that to which extent decision making in this area is based on optimal and efficient networking between involved programs and actors in the field. Research findings are showed that there is a relatively significant distribution and balance of power among actors and programs and also an network of communications and co-operations have been formed. Finally, in some of sections, there are centers of power in the network that these arose from the circumstances and needs of the country and have been formed based on purposeful policy making.

There are too many different reasons for organizational project failures. Non-supportive management, Internal resistance, and situational changes an be mentioned as some of the most important reasons. IS projects obey the same rules. Because of their considerable effect on quality and quantity of organizational output, this article tries to propose some solutions to minimize the probability of such failures in Iranian organizations. InformaticS Services Corporation, ISC, as the largest ebanking company in Iran has been chosen as case of study. Vensim software V9 applied to simulate the real situation available in ISC. By testing different solutions, it has been conducted that the most effective ones are: continuous training, estabishing sustainable management systems via process clarification and procedure deployment, helping to ameliorate contactors' financial condition, and clear written contractual relations instead of verbal agreements in all phases of the projects. The major difference of this writting compared to other articles is its concentration on project gap.

Nowadays in most of the organizations such as project-based organizations, outsourcing the projects and transferring the activities are followed by concentrating in core capabilities, reducing size, achieving the best performance and controlling and transparency of costs. Since each of the project of outsourcing commit the responsibility of performing each part project activities to a contractor, for a specific period of time and determined costs, this outsourcing process is a project. Therefore, despite its numerous advantages, in some situation it fails, that the most important reason for this failure is lack of using appropriate methods and techniques of management in risk assessment. As a result, the purpose of this paper is presenting a risk assessment model in outsourcing process using the Analytic hierarchy process and PROMETHEE methods in fuzzy environment.

In today's dynamic and competitive markets, industries and services need approaches that could help to overcome environmental challenges and products and services to offer its customers that without wasting the. Such a tool can be achieved with lean manufacturing practice. The study of literature in the supply chain, lean production models of 14 main factor was identified in the form of a questionnaire, experts and managers in the automotive supply chain was studied. ISM method specified sequence and the relationship of these factors and then path analysis technique is confirmed. In this regard were the five factors. The first level involves the wastes and customer satisfaction, the second level includes resource control and continuous improvement, the third level includes: material structure flow, supplier development and supplier selection, the fourth level includes: training and empowering, relationships with customers, relation with suppliers and structure information flow, the fifth such management behavior, staff skills and management practices are. This factor helps managers in the implementation of lean manufacturing to improve production methods and approaching the start of each factor.

The purpose of this paper is to study the relationship knowledge sharing in organization on success of talent management system with consider to social capital in petroleum industry. Main question in this article is that how can implement TM and knowledge sharing by using their relationship, Result has shown that it happens via social capital. For this purpose, 3 questionnaires for evaluating TM, knowledge sharing and SC between 174 person of human resource managers and experts in staff divisions of Iranian national petroleum company and its affiliated branches located in Tehran by using randomized classification method. 62 people with sample formula have selected. Among them, 57 were returned, which 35% of the population is formed. Analysis of data via structural equation model (SEM) has shown that mediator role of SC on the relationship between TM and knowledge sharing variables have supported. It means that focus on social capital and employ it from organizations can affect success of implementing TM and knowledge sharing variables in organizations.

Software development companies face with high environmental change due to the high level of competition for personalized products, reducing production time and high speed of emerging technologies. These organizations need to increase their agility by using agile software development methodology in order to adapt business processes with rapid changes and survive in competitive environment. Successful application of this methodology empower firms in providing value-added products specially in the analysis phase which analysts have to determine customers needs and the software architecture. At first step a comprehensive set of practical factors of evaluating and improving the success of analysis phase in agile methodology is provided. For this purpose through deeply exploring the broad literature the most significance factors were identified. Then the most influential factors have been determined for assessing the success of analysis phase in agile methodology while the software is matured. Following the analysis of survey data, it is suggested that these factors are classified as individual- customer, individual-analyst, interpersonal, organizational, managerial, technological and procedural.

The main objective of this study is investigating the survey of relevance of momentum and liquidity market state on short-term (6 and 12 months), medium- term (24 months) and long- term (60 months). Statistical sample is 270 firms that accepted during years 82- 85 in Tehran Stock Exchange and they are still working till end of Year 91. Hypothesis test results showed that liquidity market state as a factor for Separation of markets effects on excess returns in different period of times. So that the Momentum in Sets companies with high liquidity in 6 months formation and 6 & 12 months holding periods were positive and Momentum in Sets companies with low liquidity in 24 & 60 months holding periods were negative. Also, there is no significant difference between the profitability of momentum strategy in Sets companies with high and low liquidity.

Manufacturers in the current area of the necessary flexibility in a competitive environment have produced sensible understanding. Many reasons can be effective in the productivity of flexible manufacturing systems. One reason to select the dispatching rules is concerned. The selection between these rules have also largely depended on several criteria by considering their interactions that are difficult to make decisions in this regard. Also, due to the natural nature of this uncertainty by considering various angles, using traditional methods that involve certain concepts are not useful in examining these issues and not be effective. Thus, the concepts of uncertainty that the most effective tools and their use are essential and inevitable. Thus, this study tries to review, evaluate and select the dispatching rules, in which an analysis network process with respect to model characteristics with interval- valued form is provided to give a mean by a group of the decision makers in the industry that can be taken appropriate decisions in various situations. Finally, the suitable ranking for this selection is proposed.

Up to now lots of researches have been done about Total Quality Management in Iranian organizations but most of them have not been relyed on the perviouse researches. Disregarding the perviouse results of researches causes that the study of barriers and challenges of Iranian organization have been faced with some difficulties. The purpose of the present study is investigating the level of implementation of total quality management practices in Iranian governmental organizations with Meta analysis method so the results of 19 papers within 1381 to 1388 have been analysed. The results of the Meta analysis show the descending trend of top management and leadership, human resource management, strategic planning, structure and organizational culture and process management in Iranian governmental organizations while the trend of customer principel is increasing through these years. The results of this research show that Iranian governmental organizations should pay more attention to implement the total quality management practices in order to provide appropriate context for new managerial approaches.
